Intro 00:05

Welcome to Bad at Goodbyes.

On today’s show we consider the Beard’s Mallee.


Species Information 02:05

The Mariana Crow is a critically endangered avian in the Corvus family native to the western Pacific Ocean, to the island of Rota, in the United States Commonwealth of the Northern Mariana Islands.

The Mariana Crow is considered a small crow, measuring approximately 15 inches in length, and weighing roughly half a pound, with a wingspan up to 40 inches. Its anatomy is typical of the Corvus (crow) family, warm blooded with a sturdy build, strong legs, and a large brain size in relation to its body mass.

The Mariana Crow’s plumage is predominantly black, with suggestions of different colored sheen across its body: a slight greenish gloss on the head; a deep blue gloss on its back, wings, and tail and dull green-ish sheen on its lower belly. The base of the feathers are a light grayish color, sometimes appearing almost white on the neck.

Their wings are broad and powerful, allowing for agile flight and maneuverability.

The Mariana Crow’s black legs are strong and adapted for perching and walking. Each foot has four toes – three facing forward and one backward – equipped with sharp claws for gripping branches and prey.

Their beak is black and proportionally large, with a slightly hooked tip designed for foraging and manipulating food.

Their eyes are large and dark, and are set on the sides of the head, providing a wide field of vision for spotting food and potential threats. Their vision is particularly keen, allowing them to detect subtle movements and discern fine details in their environment aiding in hunting and foraging for food, spotting predators, and navigating their habitat.

They possess excellent hearing, enabling them to locate prey, such as insects hidden beneath leaves or in crevices.

While their sense of smell is not as well-developed as their sight and hearing, Mariana Crows may use olfactory cues to detect the scent of carrion or rotting fruit, for finding potential food sources.

They are opportunistic omnivores, consuming a range of foods, based on seasonality and availability.

Their diet includes a variety of invertebrates, like insects, spiders, and larvae, which they extract from crevices and foliage. Reflecting their island home, hermit crabs make up a substantial portion of their diet and they also hunt small vertebrates like gecko.

Mariana Crow also occasionally consume plants, feeding on fruits and seeds, again based on seasonality and lack of abundance of other foodstuffs.

Mariana Crow, like other corvus species, are highly social, highly intelligent beings.

They are very vocal communicators. They employ locational calls which are a high-pitched caw used while perching, foraging, or flying to announce and triangulate location with other crows. 

Mated crows use a more nasally locational call only with one another, for example when a mate is arriving at the nest or when the two are collaborating during nest building. Breeding pairs caw in a unique way specific only to their partner.

Both adult and young will “monologue” which is a series of quiet guttural and squalling sounds usually made at the nest, often accompanied by playful behaviors like ripping leaves or hammering branches. 

Mariana Crow have also been recorded making alarm calls, a series of sharp, rapid caws used to signal danger.

Mariana Crow form small family groups, generally consisting of a breeding pair and their most recent offspring, who all stay together until the young mature and disperse, these juveniles leave to seek their own mate and begin their own new family group.

The breeding season usually begins in August, but can occur throughout the year. Both parents play an active role in building the nest which is a sturdy structure made of various natural materials, including twigs, rootlets, vines, and fibers. Mariana Crow are territorial and will defend their nesting area vocally, physically, and with trickery.

In her field notes, Dr. Sarah Faegre, who has studied the Mariana Crow for over ten years, describes being cawed at, divebombed, and pecked by parents protecting their nest. She also recounts observing a fledgling fall, nearly right at her feet, and hop off awkwardly into the forest. Worried for the fledglings safely, she quickly followed, led on a winding path deeper into the woods, as the bird scrambled along the forest floor. As she got close the crow suddenly spread to full wingspan and took flight. It was in fact an adult male crow that had convincingly mimicked the physical behavior of a fledgling, to lead Dr. Faegre away from the actual nest.

So though the Mariana Crow have a range of strategies to protect their young, on average one clutch per year fails. Usually due to weather damaging the nest and eggs, or a successful predator, like the monitor lizard eating the eggs or small chicks. When a nesting attempt fails, the breeding pair will quickly rebuild and mate again. Pairs may nest multiple times each year based on initial nest failures.

The female typically incubates the eggs, usually between one and four per clutch, while the male provides protection and forges for food. Mariana Crow chicks are altricial, meaning they hatch helpless, born with closed eyes, very few feathers, and are unable to feed themselves. Both parents then share the responsibility of feeding and protecting and nurturing the young chicks. This biparental care is exhibited by the Mariana Crow throughout all stages of offspring rearing.

The chicks start to develop feathers within a few days of hatching, but it takes several weeks for their full plumage to come in, and a bit more than a month before they leave the nest at all. They are still not strong flyers at this point and continue to rely on their parents for food. They gradually learn social behaviors, speech, and how to forage for themselves under the guidance of their parents. This rearing period, during which the initial breeding pair does not breed again and the family flocks together while the young mature and learn, can last multiple years.

Young crows have been observed interacting with objects in a playful and exploratory manner like manipulating twigs and seeds, tearing leaves, hammering on branches, and repeatedly placing and removing objects from hollows. These behaviors do not seem to be related to feeding, but rather appear to be a form of exploration and play.

Relatedly, Mariana Crow demonstrate cultural transmission of generational knowledge. Adult crow have been observed teaching their young how to extract hermit crab from their shells. Adult crow do this in a consistent sequence: placing the shell, pecking at specific structural weaknesses in the shell, and skillful crab extraction, that includes snipping a weak bit of the crab abdomen and shaking from its shell. Young crow learn this by observing and then mimicking their parents, initially displaying errors in sequence and targeting. Adults will repeat their demonstration, over many months, until the young have mastered the process. Observations of captive crow have shown that this is not innate behavior, it is learned and transmitted, from parent to young, across generations.

Mariana Crow also have an unusually altruistic relationship with young who have disabilities. For example, breeding pairs have been observed extending their care for fledglings with birth abnormalities – like crossed bills or missing toes – who otherwise would struggle to feed or walk. The breeding pair were observed forgoing mating cycles for multiple years in order to nurture these young to independence.

Mariana Crow can live up to 25 years in the wild.

The earliest fossils we’ve found for the Corvid family date to the middle Miocene period, roughly 17 million years ago.

In the dream, I walk the streets at night, in the dream I am unworried by the late hour, by the darkness. I am, as ever, thinking about doors closing, and things I wish I’d said. A streetlamp flickers like the end of a flimstrip. And then, in the dream, a caw from the charcoal shadows. I do not look, I know not to catch the crow gaze with my own. But I slow my steps and deliver my whisper. I say “Please tell your mistress I seek her.”

A low rustle and then the game, to follow the crow caw in the blackness, 20 feet ahead to right, I follow, its voicing then around the next corner, I follow. And the city is getting less concrete now and I feel the brush of leaves in a deepening dark. And perhaps I’m learning crow song, at least getting better at guessing crow intention, I draw closer through full woods now and then into a place with little light, warm and black and undefined but for a bridge of dim constellations. I have imagined this path, this journey, my whole life.

I hear a far off fluttering of wing and offer my own foolish caw, a kind of thanks. And then step to the starlit bridge, to finally plead my case. In the dream.

The Mariana Crow is native to the island of Rota, in the Commonwealth of the Northern Mariana Islands located in the western Pacific Ocean, approximately 1500 miles east of the Philippines. 

The island’s bioregion is classified as tropical rainforest, characterized by lush vegetation, high biodiversity, and a warm, humid climate. Rota’s landscape is diverse, featuring rugged limestone cliffs along the coast, rolling hills in the interior, and dense forests covering much of the island. These limestone forests are their nesting site and provide foraging opportunities for the Mariana Crow.

Rota’s climate is tropical, with high temperatures reaching into the 90s °F in the summer. Winter lows rarely dip below 75 degrees. The island receives an average annual rainfall of roughly 90 inches, mainly during the wet season from July to November.

The Mariana Crow, shares its island with Rufous Fantail, Beach Morning Glory, Island Blind Snake, Swordgrass, White-throated Ground Dove, Sword Fern, Yoga Tree, Monarch Fern, Paipai, Micronesian Starling, Perfume Tree, Monitor Lizard, False Elder, Micronesian Gecko, Fruit Bat, Fig Trees and many many others.

Historically, the Mariana Crow population on nearby Guam was decimated by the human introduction of the Brown Tree Snake, an invasive predator. These snakes are not currently present on Rota, and rigorous efforts are in place to insure the snake does not migrate to the island (they have been known to hide in airplane wheelwell, accidentally hitching a ride throughout the Micronesian islands).

In the early 2000s predation by feral cats, introduced to Rota by humans, posed a threat. But recent cat control programs and human educational outreach has successfully reduced that risk.

In the mid-2010s, scientists observed the emergence of a possibly infectious syndrome known as AEX causing inflammation, anemia, and pneumonia in the Crow, leading to long illness and sometimes death. Research into the disease is ongoing.

Local human activities continue to negatively impact the Mariana Crow population. Agricultural and urban development contribute to habitat loss and degradation, and there is past evidence of crow persecution. Biologists use this term persecution to describe deliberate and targeted acts by humans to harm native species. With the Mariana Crow, for example, scientists found a breeding pair dead beneath their nest. Killed by gunshot.

And lastly typhoons, with destructive winds and torrential rain, cause nest failures, increase adult bird mortality, and can shorten breeding seasons. Human induced climate change is expected to further exacerbate the frequency and impact of these extreme weather events.

I love when I can close these episodes with a bit of good news.

Conservation of the Mariana Crow has been ongoing since the 1990s, to middling success, until, in the early 2010s researcher Dr Sarah Faegre made a breakthrough observation. She and her team found unusually high fledgling mortality rates. So, the crows were breeding successfully, young were hatching successfully, and juveniles were successfully growing into adults and forming new breeding pairs. But there was a significant drop-off with the 1-2 year olds, so the very young fledglings were not surviving into their early adulthood.

Based on that information Faegre and her team devised a totally wild conservation plan. They started stealing eggs!

You’ll recall that when a breeding pair of Mariana Crow loses a nest, like to predation or weather damage, they quickly breed again, renest, lay another round of eggs and try for a second brood. That behavior proved true in the case of egg removal. So the biologists carefully monitor wild nests and early in the breeding season collect a limited number of eggs (I believe it is up to 15 per year). The collected eggs are incubated and hatched and the chicks are hand-reared in captivity. Once past that critical 1-2 year mark, they are released back into their natural habitat. Meanwhile, our original breeding pair will have hatched another clutch of eggs, some of which will likely survive into adulthood too.

To date, 85 Mariana Crow from this captive-rear-and-release program have been reintroduced to the wild, with 61 individuals surviving. And thriving: the released crow have begun breeding themselves, producing four fledglings so far.

Nevertheless the Mariana Crow was added to the IUCN red list of critically endangered species in 1994, and their population is in decline.

Our most recent counts estimate that less than 250 Mariana Crow remain in the wild.

Intro 00:05

Welcome to Bad at Goodbyes.

On today’s show we consider the Beard’s Mallee.


Species Information 02:05

The Beard’s Mallee is a critically endangered eucalyptus tree native to Western Australia, near Shark Bay, roughly 350 miles north of Perth.

Beard’s Mallee is a small flowering evergreen eucalyptus tree that typically grows to heights of 10 to 16 feet. Its shape is directly influenced by a particular fire adaptation. The tree grows a lignotuber, which is a woody swelling at the root crown, at the top of the root system and at the base of the trunk, just below or at the soil surface.

Lignotubers are packed with dormant buds from which new stems may sprout, and starch reserves that can support a period of growth in the absence of photosynthesis.

When a plant with a lignotuber experiences damage to its above-ground parts, in the case of the Beard’s that is usual fire, then the lignotuber activates. The dormant buds within it are stimulated to sprout, producing new shoots and leaves, allowing the plant to quickly recover and resume growth and photosynthesis. The stored nutrient reserves support that initial growth until there is ample foliage for new food production.

The tree’s bark is smooth, colored pale gray, creamy-white, and sometimes presenting a soft pinkish hue.

The light green leaves of the Beard’s Mallee are narrow, curving and longer than they are wide, tapering to a point at the ends, generally measuring between 3 to 5 inches long and a quarter to a half-inch wide.

In late winter, early spring (August to October in the Southern Hemisphere), the Beard’s Mallee produces unusual capped buds, that look a little like a chess pawn that hang downward in an umbel inflorescence. Inflorescence just means a cluster of flowers, umbel describes how the stalks of that cluster grow from a single central point, resembling an umbrella.

The buds shed their cap revealing gorgeous creamy-white flowers that look a little like a fringed lampshade. The flowers are bisexual, meaning both female and male sex organs are present in a single flower, the fringe are stamen, the male pollen-producing organ. And at the center of the flower is the female organ, the pistil, and the nectaries, the nectar producing organs.

Honeyeaters, a diverse family of small bird found in Australia, drink this nectar using their long, thin bills and brush-tipped tongues. As they move from flower to flower in search of nectar, they inadvertently transfer pollen, facilitating the Beard’s reproduction.

Once fertilized, the tree develops small, brown, cup-shaped woody fruit. These mature over several months, reaching full ripeness by late summer or early autumn (February to April). They measure roughly a half inch in both length and width and once mature, these seed capsules remain on the tree. The capsules are serotinous, meaning they are fire-adapted to open in response to the presence of high heat. And so imagine, wildfire, the branches burn, the seed capsules fall, roll, are carried by fire and wind, and then open, releasing the protected seeds. This is advantageous as it ensures that seeds are released into spaces now cleared of competing vegetation, providing optimal conditions for possible germination and successful growth.

And of course after a fire, the parent plant is often able to regrow, relying on the dormant shoots and stored nutrients in its lignotuber.

I am forever-awed by the accidental iterations of evolution, like it is not surprising that a complexity of pressures over millions of years results in a being, like the Beard’s Mallee with such intriguing adaptations, but it is still totally amazing. And as I learn more and more doing this show I feel a deepening astonishment at the extraordinary confluence of factors and the tangled interdependencies that lead to life. What a gift, like even in this late moment, what a gift it is to live on our planet.

The Beard’s Mallee is native to a small region of Western Australia, specifically the sandplains between the Kalbarri National Park and north to Shark Bay. This area is considered part of the Southwest Australia Ecoregion, which is a recognized biodiversity hotspot.

This ecoregion is characterized by a Mediterranean climate, with hot, dry summers and cool, wet winters. Summer temperatures can soar to 100+ °F highs, while winter lows dip into the 40s. The annual rainfall is low, averaging 14 inches, primarily concentrated in the winter months.

The Beard’s Mallee’s habitat is a vast expanse of sandy plains, dotted with low, rolling hills and occasional rocky outcrops. The soil is predominantly nutrient-poor sand, often with a reddish or yellowish hue. Vegetation is sparse, with scattered low growing shrubs, and small trees spotting the arid landscape.

It shares this home with Yuna Mallee, Sceptre Banksia, Emu, Acacia, Malleefowl, Northern Sandplain Mallee, Bearded Dragon, Broom Bush, Grevillea, Sand Goanna, Grey Kangaroo, Ashby’s Banksia, Brushtail Possum and many, many others.


————

In the dream, an aftermath. In the dream, an ashen aftermath, a barren expanse of green burnt black, limbs and trunks, fire-licked, smoke-taste on my lips, and a sadness, an orange-lit sky. 

There is a thing humans say, one door closes, another opens. That every ending is also a beginning. In my own life, I have found that hard to place faith in. But here, in this dream, I can smell the truth of it. Of flame aching seedpods releasing their gift. Of shoots sprouting up from the ash. Terrifying change is also a promising.

And so I speak a small prayer into the char, to remember this scent, this trust, when I wake. From the dream.

————


Beard’s Mallee faces a range of anthropogenic threats. Historical transformation of land for agriculture and grazing reduced its habitat. And today, human-introduced, non-native domesticated goats that pasture in its range cause significant damage to the tree, especially young seedlings and mature individuals resprouting after fires.

Human development and encroachment continue to be an issue; one subpopulation of Beard’s Mallee was destroyed by road construction.

And human induced-climate change is an immediate threat. Global warming is increasing drought length in this already arid place, resulting in more severe and frequent wildfires.

Fire is a historic part of the Beard’s Mallee ecosystem and plays a critical role in its reproduction, but more frequent and more intense fires can destroy maturing plants before they have a chance to produce seeds, can stunt regrowth and regeneration by exhausting nutrient stores. And increased fire severity can cause the seed capsules to open too early, affecting the seeds viability.

The Beard’s Mallee is legally protected under the Australian Environment Protection and Biodiversity Conservation Act of 1999. And several conservation efforts are underway to protect the species and its habitat. Including identifying and safeguarding its ecoregion and restoring its degraded habitats, controlling invasive weeds, managing grazing pressures, and implementing fire protocols to promote natural regeneration.

There are offsite conservation efforts in place which involve the collection and storage of seeds in seed banks. Research is also ongoing to better understand the species’ ecology, genetic diversity, and potential response to future climate change threats.

Nevertheless the Beard’s Mallee was added to the IUCN red list of critically endangered species in 2019, and their population is in decline.

Most recent counts estimate that less than 250 Beard’s Mallee remain in the wild.

Intro 00:05

Welcome to Bad at Goodbyes.

On today’s show we consider The Rusty Patched Bumble Bee.


Species Information 02:05

The Rusty Patched Bumble Bee, is a critically endangered insect, native to North America, mainly in the midwestern United States.


The Rusty Patched Bumble Bee is a medium-sized bee, with six legs, two pairs of wings, a pair of antennae, and a three-part body consisting of a head, thorax, and abdomen. The reddish-brown patch of fur located on the second abdominal segment of worker and males inspires the bees common name.

Rusty Patched Bumble Bees range in size from 1/4 to 3/4 of an inch.

They have five eyes: two large compound eyes, situated on either side of the head, and three simple eyes arranged in a triangle on the top of their head.

A compound eye is composed of numerous light-sensitive units, each a separate visual receptor, with its own lens, cornea, and photoreceptor cells. That results in a kind of mosaic, kaleidoscopic seeing adapted for motion detection, light sensitivity and a wide field of vision.

The bee’s three simple eyes are thought to be used for light detection and lateral orientation.

The Rusty Patched Bumble Bee, is covered in dense fur that aids in thermoregulation, helping the coldblooded insect maintain a stable body temperature. Their fur is electrostatically charged, which aids in pollen collection, the charged hairs attracting pollen. And some hair on the bee is adapted for sensory input, detect vibrations, airflow, and even electrical fields.

Historically, Rusty Patched Bumble Bees thrived in a variety of habitats across Eastern and Midwestern North America, including prairies, woodlands, marshes, farmlands, and even urban residential parks and gardens. Places with a temperate climate, diverse and abundant flowers, as well as safe nesting sites near their food source.

Their historical range extended from Quebec and Maine in the north and east, to Minnesota to the west and to Georgia in the south. Today its population and range is fractured, and much smaller, with the largest concentrations of bees found in Indiana, Ohio, and Illinois.

Rusty Patched Bumble Bees live in colonies and are eusocial, meaning they demonstrate an advanced and complex social structure that includes cooperative care of young, overlapping generations within a colony of adults, and a division of labor into reproductive and nonreproductive groups. For the Rusty Patched Bumble Bee, those groupings typically involve one egg-laying queen, many non-reproductive female workers, and a caste of reproductive males (called drones) and females (called gynes).

The queen, of course, is responsible for initial reproduction and colony management, workers gather pollen and nectar and protect and maintain the nest, and the drones and gynes are responsible for expanding the colony and the next generation of bees.

A colony can include as many as 1000 individuals with a single queen and her colony typically sharing one nest, usually found 1 to 4 feet underground, often in the abandoned burrows of small mammals such as chipmunks, squirrels, mice, and voles. 

The nest consists of a cluster of irregularly shaped wax cells, are used to store pollen, nectar, and to rear developing young. Bumblebees do not make honey, and so unlike the rigid hexagonal combs of honeybee hives, bumble bee nests are less structured, not perfectly uniform, and the overall shape of the nest varies based on the hole it’s in.

The Rusty Patched Bumble Bee has a seasonal, annual life cycle. In the spring, a queen emerges from hibernation and starts a new colony, building the nest, laying eggs, and raising the first batch of worker bees. These workers then take over the tasks of foraging for food, caring for the young, and maintaining the nest.

Through the year, the colony grows as the queen continues to lay eggs and raise workers. In late summer, new gynes and drones are born. These reproductive bees leave the nest forever to mate and launch new colonies. 

Bumblebees mate sexually, the drone inserting his reproductive organs into the gynes abdomen. The gyne stores the sperm in her body and uses it to fertilize eggs throughout her life. This single mating event is sufficient for her to produce all the offspring she needs to establish and maintain a new colony. The drones, having fulfilled their reproductive role, typically die shortly after mating. While the new queen finds a safe place to hibernate for the winter. The following spring, the cycle begins again with the new queens emerging from hibernation to establish their own colonies.

Rusty Patched Bumble Bees typically live a year, or less.

Rusty Patched Bumble Bees primarily communicate through pheromones, chemical signals conveying information. Queens use pheromones to control worker behavior, while workers use them to mark visited flowers and signal the nest’s location.

Tactile communication through antennae sensing and physical interaction has been observed. Buzzing and vibrations also convey information, with louder buzzes thought to indicate excitement and threat.

Unlike honeybees, bumblebees cannot communicate the precise location of food sources but can indicate general direction and quality. As such workers tend to forage nearby, within a few square miles of the nest.

Rusty Patched Bumble Bees rely on pollen and nectar for all their nutrients. Pollen supplies lipids and proteins while nectar provides carbohydrates. They quickly starve without nectar and so often seek out flowers with high sugar content. Pollen is equally important, providing the bees with all the amino acids they need to survive. It also provides organic compounds that aid the bees in hormone production, communication, and disease protection. Different flowers offer different pollen types, each with varying protein and lipid ratios. And so the Rusty Patched Bumble Bees have a diverse diet, feeding on numerous species, including nightshade, milkweed, clover, bleeding heart, sunflower, willow, asters, and peas. They also play a crucial role in pollinating many important crops like tomatoes, currants, cranberries, blueberries, peppers, and squashes.


————

In the dream, the flowers sing and speak and dance and draw me to them uncanny and it is pleasure and purpose to feel petal against skin, pollen in my hair, to drink from their sweet basket. To be held and nourished and trusted, I want for little else in my life. Except of course to fly. In the dream, to fly.

————


Rusty Patched Bumble Bee behavior and activity is influenced by air temperature and weather. They do not fly in rainy, foggy, or freezing conditions, though they are able to tolerate colder temperatures compared to other pollinators due to their thick, furry bodies. They tend to be most active around dawn and dusk.

Rusty Patched Bumble Bees are generally docile and less aggressive compared to honeybees, or wasps, and only defend the territory immediately surrounding their nests and only when provoked by predators or other disturbances.

Researchers have observed evidence of play in bumblebees, seeming to interact with objects just for the fun of it. Scientists at Queen Mary University in London placed a group of 45 bumblebees in a container where they could follow a straight path to a tasty sugar solution, or take a detour to a space filled with small wooden balls. The bees repeatedly chose to go out of their way to roll the balls around seeming to play, sometimes for 30 seconds or more. There was no obvious incentive for the bumblebee’s to even go to the wooden balls, let alone roll them about. But the behavior was even repeated after initial curiosity was satisfied. The researchers can offer no other explanation other than that the bees somehow found the game rewarding.

Human encroachment leading to habitat degradation and loss pose a major threat to the Rusty Patched Bumble Bee. The conversion of prairies and grasslands across the u.s. into monoculture farms, and sprawling suburbs has drastically reduced their natural habitat. 

Other invasive farming practices like the widespread use of pesticides disrupts their foraging and reproduction. And the industrial agriculture practice of importing other pollinators leads to the spread of disease, pathogens and parasites that weaken bee populations and make them more susceptible to other threats.

Human induced climate change compounds existing and presents additional challenges. Rising temperatures, altered precipitation patterns, and extreme weather events can affect the availability of flowering plants, nesting sites, and foraging opportunities.

It is hard to overstate the fundamental and vital role that bumblebee play in their native ecosystem. In the course of their own pollen gathering, they also spread pollen, fertilizing flowers and trees, contributing to the reproduction and diversity of local plant species, ensuring the growth and longterm health and viability of plantlife in their ecosystem. This, in turn, supports other wildlife that depends on those plants for food and shelter. Bumblebee species loss has a substantive ripple effect throughout its habitat.

With many of the species we discuss on our show, it can feel like there is little immediate day-to-day impact we can have on that species’ wellbeing. Though in the case of the Rusty Patched Bumble Bee, for many of us, some relatively small efforts can help encourage their rebound. Maintaining a garden, even just adding a flowering tree or shrub to our yards, can make a difference. At the most basic, Rusty Patched Bumble Bees need nectar and pollen to survive, and plants native to their habitat like asters, milkweed, and local wildflowers are excellent sources of food. We can avoid planting invasive and non-native plants and also create untouched areas in our yards, leaving sections unmowed and brushy which can help provide safe nesting sites. While of course avoiding pesticides and chemical fertilizers that harm bees and other pollinators. And lastly, when possible we can try to avoid purchasing produce grown using the monoculture and industrial farming techniques that have undermined the bee’s habitat, that overuse pesticides, and spread disease.

The Rusty Patched Bumble Bee population is currently in decline and was added to the IUCN Red List of Critically endangered species in 2014.

Though we do not have precise individual counts, it is estimated that the Rusty Patched Bumble Bee population has declined by 92% in the last 40 years.

In a moment I would like to perform some music, in hopes of opening a space to be in contemplation of the other lives with whom we share this earth. But first I want to try to clarify a nuanced idea. This music is not like for the Rusty Patched Bumble Bee, I don’t think of the Rusty Patched Bumble Bee as like a vessel from which I extract meaning or put meaning upon. It is a living being who’s wisdom and desire is unknowable to me. And so I want this music to express my very human awe, and be a means to consider my own relationship to other life, in particular as that life nears extinction. I will sit in this space of sound, awe, contemplation, reflection. I warmly invite you to join me.

Rough Transcript

Intro 00:05

Welcome to Bad at Goodbyes.

On today’s show we consider the Giant Quiver Tree.


Species Information 02:05

The Giant Quiver Tree, is a large, succulent tree native to the southwestern African continent, specifically the arid northwest of the country of South Africa and the rugged mountains of southern Namibia.

Appearance

It is characterized by a distinctive dichotomous branching pattern, meaning each branch repeatedly divides into two equal branches, a kind of upward symmetry. Mature specimens can reach heights of 50 feet with a trunk diameter ranging from 3 to 6 feet at the base, gradually narrowing towards the top. The trunk is covered in a fissured golden white bark.

The Giant Quiver Tree has adapted for frequent drought and maximum sun exposure. Its branches are made of a fiber that is soft and penetrable, in which it stores water. In response to extremes in its climate, the can shed its leaves and branches if deemed detrimental to its survival. Those fallen hollow branches lend the Quiver Tree its name, as indigenous people would use them to store arrows.

The leaves of Giant Quiver Tree are pale green, wide, and curved, arranged in a rosette pattern at the ends of branches. A rosette is a circular arrangement of leaves radiating outwards from a central point. This arrangement maximizes sunlight exposure for each leaf. The leaves themselves have a waxy surface, an adaptation that minimizes water loss in the dry environment.

The Giant Quiver is in the aloedendron family, a genus that includes aloe vera, which may be familiar, and it too is a succulent, a term that refers to the plant’s ability to store water in its thick, fleshy leaves, its branches and trunk. The Giant Quiver Tree produces vibrant yellow flowers that hang in clusters below the leafy rosettes.

The Giant Quiver Tree reproduces sexually. It is a monoecious species, each tree produces both male and female flowers, though the giant quiver, unlike some monoecious species, cannot self-pollinate. Pollination is primarily facilitated by birds, particularly sugarbirds, drawn to the yellow flowers and their nectar. After successful pollination, seeds develop within capsules and are dispersed by wind and by gravity. Those seeds germinate most successfully when temperatures remain between 60-75°F and with some precipitation. The fertilized seeds are viable for 2-5 years. During times of drought, the Quiver will pause its reproductive cycle by not growing flowers at all.

The oldest living Giant Quiver Trees are estimated to be 450 years old. Fossil record suggests that tree aloe species, like the Giant Quiver, diverged around 18 million years ago, a distinct species since the Miocene period.


————

In the dream, reaching, a slow skyward stretching, a contented aged sunbather, in a green bonnet. In the dream, gregarious, have a little more dear, rest awhile here with me. The fox burrowed sweetly among the folds of her skirt, the sugarbird leaned against her golden shoulder. Steady and open armed for as long as memory, perennial means lasting or existing for an apparently infinite time; and it so does seem. So it does seem until the shy rain, until the long drought, and the aching thirst, and then time is finite and this is goodnight. In the dream, this is goodnight.

————


Its natural habitat is primarily concentrated in a narrow band along the border between Namibia and South Africa, specifically in the Northern Cape province of South Africa and the southern regions of Namibia.

This is an extreme habitat marked by low rainfall, high temperatures, and intense sunlight. Average annual rainfall ranges from half of an inch to 2 inches, with most precipitation occurring during the summer months in the form of short, intense thunderstorms. Temperatures can fluctuate dramatically, with scorching daytime highs reaching up to 120°F in the summer, and nighttime lows dropping below freezing during the winter.

The Giant Quiver typically grows on rocky slopes, hillsides, and dry riverbeds, sometimes forming small, isolated populations or often instances of a single solitary tree. But, in the Quiver Tree Forest in Namibia, hundreds of these trees stand together, their tall, branching forms creating an uncanny silhouette and a kind of microhabitat where patches of hardy vegetation and animal life can thrive on the forest floor.

The Giant Quiver is one of the few large perennial plants that tolerates the extreme conditions of the region. As such, it is an important source of shelter, nectar, food and moisture, especially for birds.

It shares its habitat with a richness of biodiversity: Starling, adder, mouse, Sunbird, grasses, black scorpion, fox, mongoose, praying mantis, Falcon, tortoise, grasshopper, shrubs, hyaena, Ostrich, Nightjar, Leopard, Lark, bat, Zebra, and many many others.

As for threats to The Giant Quiver Tree: it is being illegally harvested; though protected and barred from international trade, there is still a demand for this tree in the black market, particularly among collectors of rare and exotic plants. So, it is sometimes poached from its native habitat.

Human encroachment, driven by mining, is resulting in ongoing habitat loss. The development of the mines themselves and surrounding infrastructure has secondary impacts such as windblown sand dumps and new water use in an already water-scarce region.

And human-induced climate change has resulted in extreme droughts over the last 20 years resulting in both individual tree deaths and reduced reproduction across the population. Changing weather and precipitation patterns, and increasing temperatures continue to pressure an already challenged population.

Ten years ago scientists attempted to model future climate change effects on the remaining Giant Quiver habitat and population. They used two climate prediction models estimating outward to 2080, a “best case scenario” in which greenhouse gas emissions were substantially reduced in the early part of our century, and a “worst case scenario” in which emissions continued at 2014 levels. In the worst case scenario all of the Giant Quiver’s native habit would be rendered uninhabitable by heat and drought by 2080 leading to total extinction in the wild. In the best case scenario, only 8% of the Giant Quiver’s population would survive, roughly 600 trees.

Most of the Giant Quiver’s current habitat and the tree itself is protected by Richtersveld Transfrontier Park with active management, and regular monitoring of the tree and its ecosystem.

The Giant Quiver Tree was placed on the Critically Endangered Red List in 2022, their population is currently in decline.

Our most recent counts estimate that less than 7000 Giant Quiver Tree remain in the wild.

Rough Transcript

Intro 00:05

Welcome to Bad at Goodbyes.

On today’s show we consider the Axolotl.


Species Information 02:05

The Axolotl is a critically endangered amphibian native to southern North America, in Mexico, Mexico City.

Adults can range in size from 6 to 18 inches in length, with an average size of 9 inches. Their bodies are cylindrical and elongated, with a broad, flat head. Wild axolotls are typically a mottled brown or black color with gold speckles.

One of their most distinctive features is the three pairs of feathery external gills stalks that protrude from the sides of their head. These gills allow them to breathe underwater while their underdeveloped lungs, which are also functional, allow them to take occasional gulps of air at the surface.

They have barely visible vestigial teeth. The primary method of feeding is by suction.

They have four short, underdeveloped legs with four toes on their front feet and five toes on their hind feet; these digits are long and thin. Their tail is long and narrow with a fin that extends from behind their head to the tip of that tail. This is an anatomy built for speed and when threatened, the axolotl can swim up to 10 miles per hour.

The axolotl has a highly specialized adaptation: it does not heal by scarring and is capable of the regeneration of entire lost appendages regrowing limbs in a matter of months. And can even regenerate more complex structures, such as parts of their central nervous system, and tissues of the eye and heart and brain.

Axolotls have relatively simple eyes compared to other animals. They do not have eyelids, meaning their eyes are constantly exposed, making them sensitive to light and primarily adapted for detecting movement and changes in light intensity rather than forming sharp images.

Instead they rely on other senses, like their lateral line system which is a network, common to many salamander, of specialized sense receptors along their head and body, that is highly attuned to vibration, specifically water movement; they can sense changes in water currents. Their lateral line receptors also can perceive low-frequency sound. And sense the weak electrical fields generated by other organisms.

And so, between their eyes, ears, sense of smell and lateral line system, the Axolotl is able to navigate, hunt, communicate, mate, and escape predation in the dim murkiest waters of its habitat.

The axolotl is native only to the freshwater of Lake Xochimilco and and previously Lake Chalco both in Mexico City. Lake Chalco no longer exists, having been drained as a flood control measure over the first 70 years or so of the 20th century.

Lake Xochimilco persists, but only as a remnant of its ancient self, existing mainly as canals and a few developed and urbanized bodies of water in the middle of the Parque Ecológico de Xochimilco which includes playgrounds, soccer fields and spaces for wedding receptions.

Summer temps in their habit average in the low 80s °F and winter lows in the mid 40s °F. The region experiences moderate annual rainfall, averaging around 27 inches, with the majority falling between June and October.

The region is historically characterized by chinampas, an ancient agricultural technique that involved interweaving reeds and mud to create artificial islands, raised beds of fertile soil, floating gardens used to cultivate crops. They were first constructed at Xochimilco at least 600 years ago. This land has been shaped by our species for a long time.


————

In the dream, I visit. New York to Mexico City, and in the dream, because it is a dream, I am there suddenly, without the long journey and any of the trifling complexities that keep us apart. Our days together are unworried, talking and cooking small meals, we stoll revolucion, we sing in the evenings, we walk in the park. We walk in Parque Xochimilco, never knowing how close we were, how close we are, to something so precious. In the dream.

————


The actual lake bed Xochimilco is primarily composed of volcanic rock and sediment, with varying depths and a mix of submerged vegetation and open water areas that support aquatic plants, like: Water lilies, Elodea, Duckweed, and common Reeds and Rushes. As well as fauna like frog and heron and squirrel and snail and egret and fish like the Charales and the Mexclapique, alongside introduced species like tilapia and carp. A variety of invertebrates: insects, crustaceans, and mollusks live in and near the waters.

Axolotls are carnivorous and their diet mainly consists of small invertebrates, like mosquito larvae, water fleas and brine shrimp; Mollusks like snail and small clams; and small fish.

Axolotls are ambush predators, meaning they lie in wait for their prey rather than actively chasing it. They use their specialized senses to detect, and their suction feeding, to capture their prey. Once detected, they create a suction force that draws the prey into their mouth along with water. Their mouths are lined with small, backward-facing teeth that help prevent the prey from escaping. So after capturing the prey, they close their mouths and swallow it whole. They cannot chew, so they rely on digestive enzymes to break down the food in their stomachs.

They typically hunt at night when their prey is more active. They are opportunistic feeders and will consume any available food within their size range.

Axolotls are solitary and do not exhibit complex social structures. However, they do coexist peacefully in groups as long as there’s enough space and food. While occasional interspecies interactions occur, they are brief and mainly related to courtship and mating.

During breeding season, axolotls use pheromones to attract mates and communicate. During courtship, males perform a dance by vigorously fanning their tail to waft pheromones towards the prospective female. And females have been observed performing subtle body movements that seem to indicate receptivity. The male then deposits small, cone-shaped packets of sperm on the bottom of the lake. The female intakes that sperm into her reproductive organ and her eggs are fertilized internally.

Within 1-3 days after mating, the female lays hundreds of eggs, attaching them to aquatic plants or other lake bottom surfaces. The eggs hatch within two to three weeks, and the young, though vulnerable, are capable of surviving on their own. They primarily absorb their yolk sacs and develop their external gills, starting to swim and explore their environment. After a few days, they will begin to actively seek food and will gradually start to develop their limbs. By around 6-8 weeks of age, they will resemble miniature versions of adult axolotls. They reach reproductive adulthood after about one year. 

Most amphibian begin their lives as aquatic animals, unable to live on dry land: tadpoles. To reach adulthood, they go through metamorphosis, in which they lose their gills and leave the water, generally only returning to breed. Axolotl are unusual, they rarely metamorphose, retain certain larval characteristics, including keeping their gills into their reproductive adulthood and live their entire lives underwater.

The estimated average lifespan of the axolotl is 6 years.

Human encroachment, due to development and urbanization has substantially shrunk the axolotls native habitat.

And what remains is threatened by multiple stressors. Pollution, stemming from agricultural runoff and untreated wastewater, has degraded water quality. The introduction of non-native species, the tilapia and carp, has disrupted the ecosystem, creating new competition for resources and the larger fish prey upon axolotl eggs and larvae.

The small size of the wild population has also resulted in a loss of genetic diversity, a genetic bottleneck, that makes the species more susceptible to disease and less adaptable to environmental changes, such as the effects of human induced climate change.

The axolotl is protected by the Mexican government, who prohibit the capture, possession, or trade of wild axolotls without proper permits.

Conservation efforts are focused on captive breeding programs, habitat restoration, and public awareness campaigns. Researchers are also exploring the potential of reintroducing captive-bred individuals into suitable habitats, both within and outside of Lake Xochimilco, a strategy called translocation.

The Axolotl was added to the IUCN Red List of Critically endangered species in 2020 and its population is currently in decline.

It is estimated that less than 1000 Axolotl remain in the wild.

Rough Transcript

Intro 00:05

Welcome to Bad at Goodbyes.

On today’s show we consider the Underground Orchid.



Species Information 02:05

The Underground Orchid is a critically endangered flowering plant, native to Western Australia. 

The Underground Orchid is a species of extraordinary adaptation, a flower that lives mostly underground. It lacks chlorophyll, does not photosynthesize, and therefore has no leaves or green coloration. Its main body is a horizontal underground stem called a rhizome, that stores water and nutrients, that generally measures 2 to 5 inches long. Leaf-like structures, called bracts, and clusters of tiny 1/8 inch flowers sprout from the rhizome at or just above ground-level. The cream, purple and pink-ish leaf-like bracts cup and curve over the red flower clusters, looking a bit like a tulip half-buried in the earth. What appear to be flower petal are in fact the leaf-like bracts, and what appear to be stamen, are in fact the whole flowers, themselves.

Since it does not photosynthesize, the Underground Orchid relies on a complex of symbiotic relationships with a fungus and the broom honey myrtle shrub. The fungus colonizes the orchid’s roots, acting as a conduit for essential nutrients and in return, the orchid provides the fungus with a suitable habitat. This same fungus also forms a relationship with the roots of the broom honey myrtle shrub, assisting the shrub in nutrient and water uptake. The shrub, in turn, provides the fungus with carbohydrates produced through photosynthesis, and the underground orchid indirectly benefiting from the broom honey myrtle’s photosynthetic output via the fungus.

The Underground Orchid reproduces both sexually and via asexual vegetative propagation. Its sexual reproduction involves flowering, then pollination, likely facilitated by small underground or surface insects like ants and termites), and then once fertilized, seeds are produced in fleshy fruits which take several months to mature. The exact mechanism of seed dispersal remains unknown, but the fossil record suggests that small mammals like bandicoots or potoroos may have contributed to seed dispersal through consumption of the fruits.

The Underground Orchid also reproduces asexually through the extension of the rhizome, growing new off-shoots, effectively cloning the parent plant. These cloned offspring cannot fertilize each other or the parent, so though short-term survival can occur through this means it is not a viable longterm population growth strategy.

The Underground Orchid is native to Western Australia in the Corrigin area east of Perth. This is a semi-arid bushland with hot, dry summers and mild, wet winters. The landscape consists of plains and hills with sandy or sandy-loam soils. Annual rainfall is less than 15 inches per year on average, with most of the rain falling during the cooler months. The orchid exclusively grows within thickets of broom honey myrtle, often interspersed with scattered Eucalyptus and Acacia trees. These thickets provide the shade and microclimate necessary for both the orchid and the myrtle’s success.

The Underground Orchid has developed several adaptations for its low-rainfall habitat. First, obviously, it mostly grows underground, shielding it from harsh sun and drying winds. The absence of leaves minimizes water loss. And the orchid’s flowering and seed production coincide with periods of higher rainfall.

The orchid shares its habitat with: Scrub-heath shrubs, Malleefowl, Gum trees, Berry saltbush, wallaby, cockatoo, skinks, Eucalyptus, possum, Acacia, lichen, snakes, geckos, kangaroos, of course the broom honey myrtle shrub and many many more.

In the dream, in the dark, the ever cool dark, in the dream our hands entwined, an intimacy, a giving, taking, holding and waiting and reaching and growing in concert harmony and dissonance, a crescendo a blossoming on a tiny dirt stage. fruiting in that sharp first light. In the dream.

————




Due to its highly specialized adaptations, the limited availability of suitable habitat poses a significant threat to the Underground Orchid population. Its intertwined reliance on fungi and thriving thickets of broom honey myrtle challenges its spread and growth even in a stable habitat. But of course human encroachment and human induced climate change are pressuring the orchid’s native ecosystem. 

A warming climate is reducing rainfall in the region, affecting the broom honey myrtle by decreasing its biomass and its leaf litter fall. This impacts soil nutrient cycling, moisture retention, and critical fungal activity. 

Local human development and agricultural practices risk chemical spray drift and are changing drainage patterns, reducing water availability and compacting and eroding the soil. Rising salinity in the watertable, also caused by agriculture, reduces fresh water availability for these plants

Human-introduced invasive species, such as rabbits and fast growing weeds, further threaten the orchid. While the exact impact of weeds is uncertain, they likely compete with the orchid, honey myrtle and its associated fungus for soil moisture and nutrients. And weeds increase the risk of fire, which is particularly detrimental to the orchid during its flowering period.

The Underground Orchid is protected by the Australian Department of Environment and Conservation who are monitoring and surveying plant numbers and impact of threats, including early intervention into any wildfires which may threaten the species. Two habitat sites have been set aside as nature reserves.

The Underground Orchid was placed on the Critically Endangered Red List in 2020, their population is currently in decline.

Our most recent counts estimate that less than 9 Underground Orchid remain in the wild.

Welcome to Bad at Goodbyes.

On today’s show we consider the Sumatran Rhinoceros.



Species Information 02:05

The Sumatran Rhinoceros is a critically endangered mammal native to Southeast Asia, specifically Indonesia.

The Sumatran Rhino is of course a rhinoceros, a species that the fossil record suggests originated 55 million years ago. Then believed to have arrived in Asia about 20 million years ago and then the Sumatran Rhino diverged from its immediate ancestor the long extinct ice age era Wooly Rhino in the Miocene period. So, as a unique species the Sumatran Rhino is roughly 9 million years old. For context, modern humans, homosapiens are only 300,000 years old.

An adult Sumatran Rhinoceros typically stands about 5 feet high, with a head to tail length of about 9 feet. Their weight averages roughly fifteen hundred pounds. The body is stocky and robust, characterized by a long head, a short neck, a thick torso, and a rounded rear with a thin short tail covered in bristly hairs that ends in a thick tuft.

They have short, stout, well-muscled legs, each ending in three toes. Each toe is tipped with a broad, hoof-like nail.

They have a long muzzle. Their eyes are small and dark, surrounded by wrinkly skin. Their ears are relatively large and fringed with hair, they can move and turn and perk them up, aiding in detecting sounds. Their nose is broad with nostrils spread far to each side of the face. They have a prehensile upper lip, prehensile means adapted for holding, seizing, grasping, that they use to grab vegetation. They are herbivores, so they pull greenery into their mouths and then their premolars and molars are specialized for grinding vegetation. They have two horns. The frontmost horn is significantly larger, typically 10 to 30 inches in length. The second horn is smaller, rarely exceeding 4 inches. Both horns are made of keratin, the same protein that makes up human nails and hair.

Though we think of rhinos as having a kind of specialized armored skin, theirs is the same as other mammals, just thicker. It’s primarily composed of three layers: the epidermis, dermis, and hypodermis.

The outermost layer, the epidermis, provides a waterproof barrier and creates skin tone. In the Sumatran Rhinoceros, the epidermis is quite thick and covered in a sparse coat of bristly hair. This hair, though not nearly as thick as like the fur coat of other mammals, still provides some insulation and protection from the elements.

The dermis, the thick layer beneath the epidermis, contains tough connective tissue, hair follicles, sweat glands, and blood vessels that help regulate body temperature. This layer gives the skin its strength and flexibility.

The deepest layer, the hypodermis, is made mostly of fat and connective tissue. It acts as an insulator, conserving body heat.

Across all three layers the skin of the Sumatran Rhinoceros is adapted to a substantive thickness, three times what would be expected of a mammal of its size. It is believed that this adaptation is in response to now extinct predators, and to the density of the forest in its native habitat protecting it from puncture on branch or volcanic rocks.

Sumatran Rhinos are native to Southeast Asia, specifically the Indonesian islands of Sumatra and Borneo. Historically, they were found in a wider range, including China, Myanmar, Thailand, and Malaysia.

They are adapted to diverse terrains, ranging from lowland swamps and coastal areas to mountainous rainforests characterized by high biodiversity with ample precipitation and vegetation.

The climate is tropical, characterized by high humidity, abundant rainfall, and warm temperatures in the 80s year round. This region receives over 200 inches of rain on average.

Plant life includes dipterocarp trees, palms, Torchwood trees, Laurels, ferns, and orchids. Fauna includes fire-tufted barbet, tiger, tapir, graceful pitta, elephant, gibbon, Sumatran treepie and many many more.

The Sumatran Rhino shares its rainforest home with a remarkable and expansive biodiversity.

The Sumatran Rhino itself is a primarily solitary animal, living independently except for mothers with their calves, and brief in heterosexual pairs during the mating season. They establish home ranges, with males (called bulls) having territories up to 20 square miles, while females (called cows) occupy smaller ranges of 4 to 6 square miles. These ranges are spaced out for females with little overlap and interaction, but often do overlap for males.

Sumatran Rhinos are most active during dawn and dusk, primarily for feeding. During the day, they retreat to mud baths; scientists have named this behavior wallowing. It plays a vital role in regulating their body temperature and protecting their skin from parasites and insects. If no natural mud holes are available, they create new mudholes or deepen existing puddles with their feet and horns.

Research suggests that Sumatran Rhinos rotate between a few preferred wallows, using each for several weeks before moving on. They typically wallow in the middle of the day for two to four hours, and then venture out again to forage.

Sumatran Rhinos are herbivores with a diverse diet. Their preferred food sources include small trees, shrubs, and herbs. They are considered browsers, meaning they prefer foliage, rather than grazing on grasses like some other herbivores.

They are generalist herbivores and will sample a wide array of plants, but most feeding on leaves and twigs from saplings and small trees.

Using their prehensile upper lip, Sumatran Rhinos will grasp and pull vegetation into their mouths. They have specialized adaptations in their digestive tract to even break down woody branch fibers.

Although they have never been observed mating in the wild, Sumatran Rhinos are considered to be polyandrous, meaning the female will mate with several males during the breeding season. Females will indicate their fertility by vocalizing, scent marking, and raising their tails near males. Males will nudge the females and if she is receptive, they will mate. 

Pregnancy lasts 15 to 16 months, one of the longest among mammals. They birthing a single, reddish-haired approx 100 lbs calf. The new calf is entirely reliant on its mother who singularly provides food and protection for the first year and half of life and continues to nurture their offspring until they reach independence at roughly 3 years old.

Females reach sexual maturity around 6 to 7 years old, and males reach sexual maturity around 10 years old. Females give birth only once every 3 to 4 years, seeing their young to independence before mating again.

It is estimated that the Sumatran Rhino can live up to 45 years in the wild.

Though they are generally solitary animals, they demonstrate intricate social behaviors and communication within their species. They use a variety of vocalizations, including whistles, eeps, and whale-calls, so-named by scientists because it sounds a bit like a higher pitched whale song.

Let me drop the music out for a second and share a brief recording of Delilah, a 3 year old sumatran rhino calf at the Sumatran Rhino Sanctuary in Indonesia, she’s singing.

In that recording, Delilah is receiving a bath from her human caretakers, an event they report that she seems to truly relish; it’s hard not to imagine that she sings in her delight?



————

In the dream I bask in unspecified pleasure, it is barely containable, it is big and childlike, in the dream I am a child, and yet in the dream I still know that not all children have the privilege of joy and I so hold a bit of my wishings for you, that you too may have once known, or one day might know an abundant heartbloooming celebration that has no cause, no origin but that I am and I live, we are and we live and we sing it, in our own tongue for ourselves when we need, and for anyone willing to listen. In the dream.

————



Scientists believe vocalizations may serve to attract potential mates, warn others of danger and establish territorial boundaries.

They also mark territory by scraping the soil with their feet and leaving excrement. Scent marking through urine and dung also provides other rhino information about that individual’s sex, reproductive status, and individual identity.

They also communicate at a distance by bending saplings that they do not eat into distinct patterns. Scientists believe these are landmarks, to indicate a junction in a trail.

When in proximity, Sumatran Rhino appear to use body language like posture, facial expression, and ear movement to convey intentions and emotions.

This diversity and complexity of communication is significant because they are not aggressive about defending their territory; though often males will have ranges that overlap with other males they have never been observed fighting, they use non-violent behaviors to resolve resource and reproductive disputes.

In their interactions in the wild with other species, Sumatran Rhinos exhibit shyness and predator avoidance, particularly from tigers who occasionally prey on their young. Their keen sense of smell and hearing detect threats and help them evade encounters.

They share their habitat peacefully with other large herbivores like elephants and tapirs, with whom they may indirectly communicate through scent marking and vocalizations to avoid competition for resources.

The Sumatran Rhinoceros play a pivotal role in sustaining their ecosystem through habitat modification, nutrient cycling, and seed dispersal, which supports overall biodiversity and ecosystem resilience.

As they range for food they create and maintain trails, forging corridors through inhospitable terrain. These trails are used by generations of rhino and also by elephant, deer, boar, and wild dog.

Their ability to dig for water leads to the creation of new waterholes, helping other fauna in their habitat by creating additional access to underground water supply.

Their wallowing behavior also contributes to nutrient cycling. When they roll about in the mud, the rhinos extract enriched sections of fertile soil that coats their skin and they carry these essential nutrients to other areas stimulating plant growth there.

Additionally, they act as seed dispersal agents. Which I love considering. We’ve discussed plant reproduction adapted for wind and water and gravity seed dispersals. Now, rhino dispersal. Their substantial daily dietary intake results in a lot of nutrient-rich dung containing a diverse array of seeds facilitating the propagation of plant species over considerable distances.

All of which directly and indirectly supports both flora and fauna in their habitat. I feel like we are learning this again and again each week: Everyone is vital in every ecosystem.

Threats to the Sumatran Rhino include immediate human encroachment on their habitat, the long term effects of human induced climate change, historical overhunting, and current poaching.

Human encroachment includes forest conversion into commodities and plantations, road development, and natural resource collection, like logging and fishing, all of which reduce the rhino available habitat and increase competition for the resources therein.

Human induced climate change is affecting weather patterns in Sumatra, including unfamiliar shifts in the jet stream El Nino, resulting in decreased rainfall, increased wildfires, and increased risk of extreme damaging weather events.

Historical overhunting has led to a dire population bottleneck, resulting in inbreeding which affects the longterm genetic viability of the species.

Poaching is driven by the demand for the supposed medicinal properties of rhino horns and their male reproductive organs. Petty narcissistic idiot human men, think they will become better sexual partners though ingesting rhino parts, and there is lucrative international blackmarket trade in this foolish cruelty.

Fortunately the Sumatran Rhinos habitat falls within three Indonesian Protected Reserves: Bukit Barisan National Park, Gunung Leuser National Park, and Way Kambas National Park the last of which also houses the Sumatran Rhino Sanctuary. The Rhino has been legally protected internationally since the mid-1970s and Rhino Protection Units have been established by Indonesia’s Ministry of Environment and Forestry to actively combat poaching.

Captive breeding and release programs have been explored since the early 1980s with low success, though the Cincinnati zoo welcomed surviving calves in 2000 and 2013.

The Sumatran Rhinoceros was added to the IUCN Red List of Critically endangered species in 2019 and its population is currently in decline.

It is estimated that less than 50 Sumatran Rhinoceros remain in the wild.

Rough Transcript

Intro 00:05

Welcome to Bad at Goodbyes.

On today’s show we consider the Jellyfish Tree.



Species Information 02:05

The Jellyfish Tree is a critically endangered tropical tree native to the Seychelles Islands, in the Indian Ocean, roughly 900 miles east of the African continent.

The Jellyfish Tree is a small tree, typically reaching heights of roughly 40 feet. Its trunk is slender, with dark, fissured bark. Branches are numerous and spreading, resulting in a dense, rounded crown of foliage. Its vibrant green leaves, that grow up to 3 inches in length, are glossy and leathery in texture, with wavy, slightly scalloped edges.

The Jellyfish Tree is andromonoecious, meaning male and bisexual flowers present on the same individual. These small, white blossoms measure about a half-inch in diameter, grow in downward hanging clusters and feature many long, thin stamens. Stamen are the pollen-producing male reproductive organ. So, the upside down cupped flowers have numerous stamens that radiate down and outwards, which do, in fact, resemble the tentacles of a jellyfish.

These flowers are primarily pollinated by the wind, though insects like flies and small bees may also play a role. The tree’s copious pollen production seems adapted for wind pollination, but the presence of some nectar in the flowers suggests an adaptation to attract insect pollinators.

The Jellyfish Tree has a relatively long reproductive cycle. Flowering and pollen-release typically occur in the late dry season, roughly September, October, November. After successful pollination, fruit development is gradual, with mature fruit appearing between 6-9 months later, late in the following spring, early summer.

The small, round roughly 1 inch fruits begin as green and gradually turn reddish-brown. When the fruit dries, its outer layer dehisces, meaning it splits open, at the top, into a kind of umbrella shape, a jellyfish-ish shape. So the fruit opens, and inside, the seeds are held within a network of fibers, and this structure aids in wind dispersal, like how an umbrella catches big gusts. The seeds have papery wings and when blown from the opened fruit, disperse widely. This dispersal process can take days or even weeks, depending on wind conditions and the distance the seeds travel.

In the wild, Jellyfish Tree seeds have very low germination rates. Scientists suspect they need very specific conditions, possibly involving high humidity, or particular soil microorganisms to successfully germinate.

The germination process is basically the awakening of a dormant seed into a new plant. For that process to begin, certain environmental conditions need to be met. These conditions vary from species to species, but a quick overview in general we’re looking for presence of water, optimal temperature, presence of oxygen, presence or absence of light, and soil conditions like depth, acidity, or nutrient content. So in the case of the jellyfish tree, scientists are uncertain what specific conditions are critical to triggering germination, though they suspect humidity likely plays a role.

Once initiated, germination begins with imbibition, where the seed soaks up water, swelling the seed, weakening the seed coat, and activating internal enzymes. Those enzymes break down stored food reserves within the seed, transforming them into usable energy for rapidly growing cells. The internal pressure from the growing cells causes the weakened seed coat to rupture. The radicle pushes through this opening, emerging into the soil. Radicle is the name given to the first part of a seedling to emerge from the seed, like the first embryonic root.

No matter from which direction the radicle emerges, it will grow downward. This adaptation is called geotropism, plant growth in response to gravity. This is so amazing. So a quick simplified explanation of this. Within the cells of the radicle are starch-filled statoliths and the hormone auxin which inhibits cell growth. The statoliths are heavy, starch filled and due to gravity sink to the bottom, displacing the auxin. The auxin accumulates on the upper side, prohibiting growth and so as the root cells grow and divide, they do so downwardly (away from the auxin).

This downard growth is critical in ensuring access to the water and soil nutrients necessary for survival. It also anchors the young seedling in the ground.

With the first roots established, the stem begins to grow upwards emerging from the soil. The first leaves soon follow initiating food production, photosynthesis. Food that powers further growth and gradual maturation.

After a few years, it reaches the sapling stage, a phase marked by strengthening of root, trunk, and branches. And eventually with time and the right conditions, the sapling grows into a mature Jellyfish Tree, ready to produce flowers and the seeds that will continue the reproductive cycle. This entire process, from seed dispersal to a mature tree capable of reproduction, can take decades.



————

In the dream, I am, as ever, a disappointing student. In the dream when I study in the shade of the deep green teachers, the lighteaters, the breatheworkers, my attention wanes. At first I am cherishing the slow language of wind carrying seed, and feeling inspired to open to our earths’ forces, inviting them to affect my path, and then I’m thinking about lunchtime. At first I marvel and imagine modeling a striving downward growth, a rooting, holding firm in place, and then I’m wondering about who might want to kiss me. And though I repeatedly fail my lessons, worrying about money, cranky when the train is stalled, my teachers persevere, remain encouraging with their foliage shimmering. And so I will, once again, commit to my studies and promise to be a better listener, in my days and in the dream.

Based on genetic studies scientists estimate that the Jellyfish Tree diverged from its closest relatives during the Late Cretaceous period, around 60 million years ago. But the Jellyfish Tree has leathery, waxy leaves, that reduce water transpiration, suggesting it is drought tolerant, which is curious, because it lives on a wet island. Scientists hypothesize these adaptations evolved when the Seychelles islands were still a part of the mainland of the ancient supercontinent Gondwana which would make the Jellyfish Tree over 150 million years old as a species.

Let’s take a quick tangent into prehistoric plate tectonics. This is a simplified timeline of how the Seychelles formed:

Around 170 million years ago, Gondwana, the giant supercontinent, which encompassed modern-day South America, Africa, India, Antarctica, and Australia, began to split apart. The Indian subcontinent drifted away from Africa, and a fragment of continental crust broke off from it. This fragment eventually became the Seychelles microcontinent.

The Seychelles microcontinent, including the granite that forms the islands’ bedrock, continued to drift northward with the Indian subcontinent. But then approximately 65 million years ago, the Seychelles microcontinent separated from India as the Indian Plate continued to move northward. The Seychelles remained, now isolated in the middle of the Indian Ocean.

Over tens of millions of years, the granite bedrock of the Seychelles was eroded and shaped by weathering and wave action leading to the formation of the diverse landscapes, beaches, and unique granite rock formations seen on the islands today. 

These rock formations are the Jellyfish Trees’ contemporary home.

The Jellyfish Tree is solely found in a roughly 25 square mile area, on Mahé island in the Seychelles, in the western Indian Ocean, all populations growing less than two miles from the coast.

This area is the Seychelles’ Granitic Islands Ecoregion, which is characterized by lush, tropical forests, tall granite peaks, and expansive beaches. The climate is tropical, with warm temperatures year-round. Summer highs typically reach the mid-90s, while winter lows rarely dip below 75°F. Annual rainfall is abundant, averaging 110 inches of precipitation, with the wettest months occurring from December to February.

The Jellyfish Tree has adapted to a specific niche within this ecoregion. It clings to crevices and cracks on exposed granite slopes and inselbergs. Inselbergs are isolated hills, ridges, or small mountains that rise abruptly from otherwise flat plains, so like a single extrusion popping out from a flat landscape. These areas are characterized by shallow soils, intense sunlight, and occasional strong winds. 

The Jellyfish tree shares this habitat with Flying fox, pitcher plant, Stilt palm, Tiger Chameleon, magpie robin, Bamboo, scops owl, palm frog, Kestrel, Blue Pigeon, Brush-footed Butterfly, Tree fern, Vanilla orchid, and many more.

Soon after the arrival of first settlers on Mahé in the late 1700s, the forests of the island were exploited for timber and cleared for agriculture and plantations. By the late 1800s the viable habitat for native plants was greatly reduced with few patches of native forests remaining. Additionally the anthropogenic (meaning human-caused) introduction of alien species has impacted native forests over the last 150 years. Competition for resources like sunlight and soil-nutrient has restricted native species to less hospitable environs like the granite outcrops where we find the Jellyfish Tree today.

Since the early 20th Century, the species was thought to be extinct in the wild, until a stand of native trees were ‘rediscovered’ in the 1970s.

Today, habitat loss and invasive species continue to threaten the Jellyfish tree, deforestation for agriculture and development, and non-native plants that outcompete the Jellyfish tree for essential resources, hindering its growth and ability to reproduce. 

Additionally, human induced climate change, with rising temperatures, increased wildfires, altered weather patterns, and potential sea level rise pose further threat.

Jellyfish Tree propagation programs are ongoing at the Kew Royal Botanic Gardens, Biodiversity Center Mahé, Royal Botanic Garden of Edinburgh. Three of the known native populations of the jellyfish tree are within the Morne Seychellois National Park, but the tree itself is not legally protected.

The Jellyfish Tree was added to the IUCN Red List of Critically Endangered species in 1998, and their population is in decline.

Our most recent counts estimate that less than 90 Jellyfish Tree remain in the wild.

Intro 00:05

Welcome to Bad at Goodbyes.

On today’s show we consider the Red Wolf.



Species Information 02:05

The Red Wolf is a critically endangered mammal native to southeastern North America, specifically the coast of North Carolina.

The Red Wolf is a medium-sized canid with a slender build, measuring roughly 5 feet in length and averaging roughly 60lbs. They stand roughly 2 feet tall, measured at the shoulder.

They have a long, narrow muzzle and a wide head with large, pointed ears. Their legs are long and slender, with large paws, four toes on each hind paws. Four toes on the front paws plus a dewclaw, which is a vestigial toe located slightly above the paw, that aids in traction and gripping prey. It has a digitigrade stance, meaning it walks on its toes, an adaptation that contributes to highly-agile movement.

The coat of a Red Wolf is a mix of colors, primarily brown, beige, and grayish black, with a red tinge often highlighting the ears, head, and legs. This coloration helps the wolf blend into its habitat. The fur is medium-length, providing insulation and protection from the elements. In winter, the reddish hues become more prominent.

They have a medium-size black nose, and their sense of smell is exceptional, allowing them to detect prey over long distances, identify pack members, and interpret scent markings left by other wolves.

Red Wolves typically have yellow or amber-colored eyes. Their vision, while not as specialized as their sense of smell, is well-adapted for both daytime and nighttime hunting. They possess good low-light vision and a wide field of view, enabling them to detect movement in potential prey.

They have large ears, in relation to their head size, and their hearing is acute, capable of picking up faint sounds from prey or other wolves.

Red Wolves are highly social animals, living in packs that typically consist of a breeding pair and their offspring from multiple generations. Within the pack, there is a defined hierarchy, with the breeding pair holding the dominant position, leading the pack in hunting, defending territory, and raising young. The social dynamics of Red Wolf packs are complex. Cooperation and coordination are essential and individual wolves take on different roles throughout their lifespan. 

Communication within the pack includes a range of vocalizations, body postures, and scent marking. Howling serves as a long-distance communication tool, used for territorial displays, rallying pack members, and maintaining social bonds. Other vocalizations include barks, whimpers, and growls, each conveying information about the wolf’s emotional state or intentions.

Red Wolf also rely on nonverbal communication, like nuzzling and licking each other’s faces as a sign of affection and greeting. This is particularly common between breeding pairs and between parents and pups.

Similar to domestic dogs, Red Wolf will wag their tail to express happiness and excitement.

And though subtle, Red Wolf also communicate through facial expressions such as ear position, twitching their noses, baring teeth, and narrowing eyes.

Play behavior has been observed in both young and adults, which is thought to reinforce social bonds, establish hierarchy and to help young wolf practice important skills.

Red Wolves are monogamous, forming strong pair bonds that often last a lifetime. Courtship behaviors involve play, grooming, and scent marking. Mating and birthing typically occurs once a year, mating between January and March, with a gestation period of about two months, so birthing in April or May.

Den are carefully selected by the breeding pair, often in secluded areas like hollow logs, burrows, or dense vegetation, providing a safe haven for new pups, protection from predators and the elements. The female gives birth to a litter of 3 to 6 pups, although larger litters of up to 12 have been recorded. Newborn pups are blind and deaf, relying on their parents for nourishment.

Both parents play an active role in raising the pups, with the male often bringing food back to the den while the female nurses and cares for the young. Packs are alloparental, meaning other packmembers, usually older siblings from previous litters, also contribute to pup rearing, providing protection, grooming, and play. As pups grow, they begin to explore their surroundings and learn essential skills like hunting and social interaction from the adults.

Red Wolves reach sexual maturity around 1-2 years old, but they continue to develop physically and socially for several years. In this extended period of development they learn essential skills for survival, like hunting strategy, and complex communication and social interaction.

On average, in the wild, Red Wolf live about 8 years. 

Red Wolves are opportunistic carnivores, meaning their diet adapts to the available prey in their environment. Their primary food source is white-tailed deer. They also consume smaller mammals like rabbits, rodents, and raccoons. They are adaptable feeders, and their diet will vary seasonally depending on the availability of prey. They may also scavenge carrion or consume fruits and berries when other food sources are scarce.

Red Wolves employ a combination of stealth, speed, and endurance to capture prey. They often hunt at dawn and dusk, taking advantage of low light conditions to stalk their prey undetected. Working cooperatively as a pack, they can successfully hunt larger animals like the white-tailed deer, which a lone wolf would be unable to subdue. Once a kill is made, the wolves will consume the most nutritious parts first, such as the organs and muscle tissue. The Red Wolf occupies a top position in its food chain.

Historically, the Red Wolf’s native habitat once encompassed a vast area of the southeastern United States, stretching from Texas to Pennsylvania. Today they are restricted to roughly 250 square miles on the North Carolina coast, within the Alligator River National Wildlife Refuge, roughly 150 miles east of Raleigh.

This is the Mid-Atlantic Coastal Plain bioregion, a landscape characterized by low-lying terrain and abundant waterways including brackish marshes, hardwood swamps, evergreen shrub bogs, and pocosin wetlands. Pocosins, unique to the southeastern US coast, are shrub-covered wetlands perched atop sandy rises, forming a “swamp-on-a-hill.”

It’s a humid subtropical climate, with four distinct seasons, with hot summers and relatively mild winters. Summer highs reach the 90s °F, winter lows dip to just around freezing. The area receives 55 inches of annual rainfall resulting in lush greenery.

The Red Wolf shares this habitat with Barred Owl, fetterbush, scarab beetles, Black Bear, swamp lily, Common Yellowthroat, White-tailed Deer, bald cypress trees, Water Moccasin, Green Heron, American Goldfinch, River Otter, Resurrection Fern, Iris, Bald Eagle, Opossum, Swallowtail Butterfly, Rose Pogonia, Prairie Warbler, Eastern Box Turtle, Monarch Butterfly, Brown-headed Nuthatch, Wax Myrtle, Raccoon, Carnivorous Pitcher Plants, Great Egret, Eastern Cottontail Rabbit, American Alligator, Spanish Moss, Yellow Fringed Orchid, Fireflies, Marbled Salamander, and many many more.

In the dream, there are no guns, in the dream there are no men with guns, that is all, that is the whole dream. A narrow dirt trail, through thick green woods, trod by generations of the pack. The long lingering scent of family.

And no smell of man, or of gunsmoke. That’s all, a forest path and no men with guns, in the dream.

————



The historic decline of the Red Wolf population stems from multiple overlapping anthropogenic activities, anthropogenic, simply means human-caused. 

Human encroachment is a major factor in the loss and degradation of their habitat. Extensive land clearing, throughout the Southeastern US, for agriculture, logging, and development has drastically reduced the forests and wetlands of the Red Wolf’s native environment.

From the late 18th through the early 20th century, private and government-sponsored predator control programs resulted in the widespread killing of Red Wolf. Wolves are often perceived as a threat to livestock and game animals, leading to their sanctioned slaughter via trapping and individual and organized hunts with firearms.

Relatedly, the overhunting of white-tailed deer, for food and sport, the Red Wolf’s primary prey, has also contributed to their decline.

Today, Human-induced climate change poses an imminent threat. Their current habitat rests just 3 feet above sea level and federal climate scientists forecast 2-7 foot sea level rise in this area of the North Carolina coast by the end of this century.

But currently the leading cause of death and population decline amongst wild Red Wolves are vehicle strikes and gunshots. Negligent human drivers running them over with their cars and trunks. And cowardly small minded human landowners with easy access to underregulated firearms illegally shooting them.

The Red Wolf was first listed as “threatened with extinction” under the Endangered Species Preservation Act in 1967. With the passage of the Endangered Species Act of 1973, the Red Wolf’s status was elevated to “endangered,” granting it even stronger legal protection.

At that time, the U.S. Fish and Wildlife Service initiated a captive breeding program. Over 400 canids were captured from the remaining wild population. But only 14 were deemed pure Red Wolf and formed the foundation of the captive breeding program. Despite these efforts, the Red Wolf was declared extinct in the wild by 1980.

But in 1987, the Fish and Wildlife Service reintroduced a small group of captive-bred Red Wolf to the Alligator River National Wildlife Refuge. The animals began to establish territories, form packs, and successfully reproduce in their native habitat. This is a substantive conservation accomplishment, the Red Wolf was rewilded.

Throughout the 1990s, the Red Wolf population at Alligator River Refuge steadily grew and by the mid-2010s, the Red Wolf population had reached an estimated 120 individuals. 

In the last decade though, the wild population of Red Wolf has been in decline, due to, as mentioned before, poaching and vehicle strikes. To address these issues, the Fish and Wildlife Service has intensified law enforcement efforts, installed wildlife crossing signs and fencing to reduce road mortality, and increased public outreach and education programs.

The Fish and Wildlife Service continues to maintain the captive breeding program, systematically studying, tracking and reintroducing Red Wolf into the wild. I would like to share with you a few highlights from the Fish and Wildlife Service’s June 2024 Red Wolf Recovery Program Update. I found this report oddly moving, so I compiled five entries and will read them to you now, pretty much verbatim.

I should note that the Red Wolf wild population is all tagged by numbers, so the following numbers refer to specific individual wolves.

  • In January 2024, four of the wild Red Wolf pups (2499M, 2500M, 2502F and 2503F) born into the Milltail family group on Alligator River National Wildlife Refuge in Spring 2023 were captured, fitted with orange collars with orange reflective material, and re-released. 
  • In February 2024, a wild female Red Wolf (2359F) was captured by private trappers and handed over to Red Wolf Recovery Program biologists. To try and create a new breeding pair, she was placed in an acclimation pen in Pocosin Lakes National Wildlife Refuge with a male (2443M) born in at the Endangered Wolf Center as part of the Red Wolf Captive Program. They did not have a litter, so 2359F was released in June 2024. For now, 2443M will remain in the pen and future attempts will be made to pair him with a wild female and release them if successful.
  • On February 25, 2024, an adult wild female Red Wolf (2538F) was captured on private lands and added to the known population. She is estimated to be 7 years old. 
  • On April 8, 2024, a wild female Red Wolf (2280F) was captured after exhibiting uncharacteristic behavior for her, such as being visible close to open farm field roads, acting very lethargic, and appearing to have vision issues. She was diagnosed with an untreatable cancerous mass on her brain and the decision was then made to humanely euthanize her.
  • Last December, a wild female Red Wolf (2413F) was captured by Red Wolf Recovery Program biologists and placed in an acclimation pen with a male (2444M), born at the Endangered Wolf Center to try to encourage a new breeding pair. This was successful and this April the new pair had a litter of 5 pups in the acclimation pen and they were all released in late May 2024. The family group moved a few miles away from the acclimation pen and settled in; 2444M appeared to be transitioning well into the wild and as a new father. Tragically, his life in the wild was cut way too short and he was a vehicle strike mortality on Highway 64 on June 5. Monitoring of 2413F and the pups will continue, and feasible management actions will be taken to assist with survival of the pups, if possible, after the loss of their father.


Though there are many reasons to celebrate the Red Wolf conservation program as a profound and frankly species-saving success, nevertheless the species has been considered Critically Endangered on the IUCN Red List since 1996 and their population is currently in decline.

Most recent counts estimate that less than 20 Red Wolf remain in the wild.

Rough Transcript

Intro 00:05

Welcome to Bad at Goodbyes.

On today’s show we consider the Chinese Swamp Cypress.



Species Information 02:05

The Chinese Swamp Cypress is a critically endangered conifer native to southeast Asia, specifically south and southeastern China, Laos, and southern Vietnam.

The Chinese Swamp Cypress is a deciduous conifer that reaches 65-100 feet in height with a trunk diameter averaging 2 feet to 4 feet, though a recently discovered stand in Laos had individuals whose trunks ranged from 6 to 11 feet in diameter and reached heights over 150 feet.

It generally grows in a pyramidal, or cone shape, like a classic christmas tree with spreading lower branches and upward pointed but drooping branches at the top giving the tree a kind of softened silhouette. The bark is thick, grayish-brown, and as it ages the bark presents vertical fissures revealing a rich red color from the cambium. The cambium is the cellular layer right beneath the bark, these are actively growing cells that differentiate into new bark or new sapwood.

Quick simplified cross section of a tree trunk:
The outer bark, which I think we all know (and love) is the tree’s protective layer. It keeps out excess moisture during heavy rain, and holds in moisture during dry spells. It insulates the tree against cold and heat, and protects against insects.

The second layer is the inner bark, which moves nutrients throughout the tree.

Then the cambium, which as mentioned, is the growing layer. It responds to hormones to either become new bark or new sapwood.

And then next, sapwood is the tree’s pipeline for moving water from the tree’s roots up to the branches and leaves. As cambium cells become new outer rings of sapwood, inner ring cells become heartwood.

So then the last layer is the heartwood, the sturdy central core of the tree. These cells are technically dead, but they do not decay and remain stable and strong as long as the outer layers of the trunk are intact.

So with the Chinese Swamp Cypress, as the tree ages its bark layers split, or fissure, in rough vertical lines, so we can see that red cambium layer beneath.

The root system of the Chinese Swamp Cypress grows pneumatophores, (commonly called Cypress knees) which are these woody structures that grow upward, vertically from the roots, extending above the ground in various shapes, ranging from small knobs to tall, pointed projections. Scientist are uncertain of the specific role these growths play, though there are three leading proposed hypotheses:

One, that cypress knees facilitate the exchange of gasses, primarily oxygen, between the tree’s roots and the atmosphere.

Two, the knees may act as anchors, providing additional support for the tree in soft, swampy soil.

Three, that cypress knees help trap and accumulate sediment around the base of the tree, so protecting the roots from erosion and creating a more nutrient-rich environment.

In the Chinese Swamp Cypress these knees can extend as far as 20 feet from the base of the trunk.

The branchlet system of the Chinese Swamp Cypress is dimorphic. Um, two terms to unpack from that sentence. Branchlet, picture a tree, its trunk, the branches that sprout from the trunk, and then twigs, stems, little bits that sprout from the branches are called branchlets. And then the other term, dimorphic, just means taking two forms. So the branchlet system is dimorphic, a single branch will have some branchlets that grow long slender needle-like leaves, and other branchlets that grow small, wider, overlapping scale-like leaves.

The Chinese Swamp Cypress is deciduous, meaning it sheds its leaves annually, this is unusual for conifers, and is particularly specialized in the Chinese Swamp Cypress based on the branchlet system. The needle-like leaves will transform into a really beautiful deep reddish-brown color in autumn and shed in the winter, while the smaller scale-like branchlets persist throughout the year.

The Chinese Swamp Cypress is monecious, it has both male and female reproductive organs flower on the same individual. Its flowers are inconspicuous, which is a botanical term for flowers that do not have showy bright colors or strong fragrances, they’re not adapted to attract pollinators like birds or insects. The Chinese Swamp Cypress is wind-pollinated. Male cones hang downward in tassel-like clusters and produce large amounts of light and powdery pollen, easily carried by the wind. The female cones, that bud in a 1in pear shape, have sticky scales that capture the pollen grains as they blow by.

Once fertilized, the female cones develop into seeds, gradually maturing, expanding and hardening into woody structures. Unlike many other conifers, the mature cones of the Chinese Swamp Cypress disintegrate, breaking apart to release the ripened seeds. These winged seeds are then carried, again by the wind, to new soil, where they have the potential to germinate, root, sprout and grow into new saplings.



————

In the dream, I am myself, um, sadly, I want to dream mysteriously, as other, expansively, and yet in this dream I am me, hairless thin skinned mammal more than halfway through projected lifespan, unlikely to reproduce. But, joyfully in the dream I somehow have a slower sense of time. Without impatience, without the phantom vibrate of my phone, I can watch the long windings of the wind and the pollen on it and the coneflower fertilized, green growing brown, woodening, and the months are passing easy now, without regret. And then the slow disintegration of cone to reveal fluttering seeds. Another journey on the wind, many scattered to the stream, many snack for spotted Wren, many fall on stone. Yet one into a soft soaked silt embrace; a kind of hopefulness I think. The kind worth waiting for, in the dream.

————



The Chinese Swamp Cypress is native to the subtropical and tropical regions of south and southeastern China and Laos and Vietnam. These are moist lowland and swamp biomes characterized by warm temperatures, high humidity, and abundant rainfall.

The tree grows in and along the banks of slow-moving rivers, in flood deltas, and in swampland. These are wetlands, interspersed with patches of drier land with terrain that is generally flat or gently sloping; the water table is close to the surface. Soils are nutrient-rich, composed of loose clay and silt deposits and organic matter accumulated over time. Well-adapted to these waterlogged conditions, Chinese Swamp Cypress have been observed thriving in waters even up to two feet deep.

The climate of this region is characterized by hot, humid summers with temperatures reaching the 90s, and mild winters with temperatures rarely falling below 45 degrees. Annual rainfall is high, averaging roughly 70 inches per year, with the majority falling during the monsoon season, from May to mid-October.

The Chinese Swamp Cypress is a keystone species in this wetland environment, providing essential habitat and resources for a variety of life. Its foliage offers shelter and nesting sites for birds, while the submerged roots provide refuge for fish and other aquatic creatures. The cypress knees, which rise above the waterline, create microhabitats for organisms like algae and invertebrates. Its trunk, knees, and extensive root system stabilize the soil, preventing erosion. Its annual needle-fall contributes to nutrient cycling in the ecosystem.

It shares its habitat with Japanese Cedar, White-winged Duck, Hydrangea, short-tailed scimitar babbler, giant muntjac, Spotted Wren Babbler, Chinese Tupelo, red pine, fig, Wild boar, Annamite striped rabbit, Box-Leaved Holly, Japanese Winterberry, the recently described bovine mammal Saola, Cinnamon Fern, Red-collared Woodpecker, water gum, Magnolia, crested argus and many many more.

We have fossil record of the Chinese Swamp Cypress’s genus dating from the Cretaceous period, roughly 100 million years ago. Meaning dinosaurs grazed its branches and it survived the K–Pg extinction event, the asteroid impact and resultant climate upheaval 66 million years ago, which wiped out three-quarters of Earth’s plant and animal species including all non-avian dinosaurs. The Cypress survived.

It’s estimated that the oldest currently living wild specimen is over 650 years old.

Historically the Chinese Swamp Cypress has suffered severe population decline due to over-harvesting. The

The tree’s water-resistant, decay-resistant, scented wood has been extensively logged for building houses, furniture, boats. Today, though it is protected, it is still being illegally poached and is highly sought-after on luxury timbre black markets.

Human encroachment, both historically and currently, have profoundly diminished the tree’s native habitat: so things like agricultural expansion, urbanization, infrastructure projects. And, the resultant pollution contaminates surface and groundwater, affecting the tree’s growth and overall health.

Human induced climate change also poses a growing risk. Increasing temperatures and specifically changes in rainfall patterns are disrupting the wetland ecosystems the cypress thrives in.

The entire known population of Chinese Swamp Cypress in Laos is within the protected Nakai–Nam Theun National Park. The trees in Vietnam are protected in the Earal and Trap Kso nature reserves. There appear to be no remaining wild plants in China.

The Chinese Swamp Cypress was added to the IUCN Red List of Critically Endangered species in 2010 and its population is currently in decline.

It is estimated that less than 400 Chinese Swamp Cypress remain in the wild.

Intro 00:05

Welcome to Bad at Goodbyes.

On today’s show we consider the Sinai Baton Blue Butterfly.



Species Information 02:05

The Sinai Baton Blue, is one of the world’s smallest butterflies, roughly the size of a thumbnail. Like look at your thumbnail and imagine a butterfly, it’s so tiny.

Its body is long and cylindrical, approximately a quarter inch in length, with a wingspan roughly three quarters of an inch wide.

It has a segmented body divided into three main sections: the head, thorax, and abdomen.

Two antennae are attached at the top of the head. These antennae are sense organs tuned to the smell of flowers, nectar, and to the pheromones of potential mates. They’re also thought to aid the butterfly in balance and directionality. Flying things have a different relationship to up and down compared to like walking beings. And so the antennae help the butterfly locate itself in space.

The butterfly has two compound eyes on the sides of its head. Compound eyes are made up of many small ommatidia, which are these clusters of photoreceptor cells that are pointed in slightly different directions. This allows the butterfly to see forwards, backwards, above and below themselves all at the same time, as well as interpret color and ultraviolet light. Their brain stitches all of this information together into a kind of fractured composite image of the world.

At the front underside of the head is the proboscis, the butterfly’s like mouth, mouthpart. It is a small wire-like structure that uncurls outward to drink liquids like water and nectar, like a straw.

The thorax is the middle section of the butterfly’s body, with six legs attached to the underside. These legs are for walking and climbing and balancing, and also for tasting. Butterfly feet, called tarsus, have specialized receptors that pickup chemical information from the surfaces they land on, like leaves and petals, which helps them identify potential food sources and promising host plants for their young.

In the dream colors, enormous. In the dream colors, enormous, kaleidoscopic, psychedelic, savory, and sweet. Magenta, Mauve, Blush, Primrose, Pinks, Pale, Antique, Cream, Candle, Whites, Kelly, Ecru, Emerald, Seafoam, Greens. And also all the new colors I now can see beyond and between the colors I’ve known. Color I can smell on the wind, color I can taste as I brush against it. In my language there is no name for the flavor of flower-petal against fingertip. There is no word for the taste of greenleaf on skin. Our earth holds a secret world of stunning abundance, much that I can never know. And so instead I dream. I dream.

————



Most butterfly, including the Sinai Baton Blue have four wings, two upper wings, and two lower hindwings, that are all attached to very strong thorax muscles that flap the wings in conjunction. 

The wings are covered in tiny, thread, or hairlike color scales. These scales, unique to butterflies and moths, present in three types: pigmented, diffractive, and androconia. Pigment scales hold colored chemicals that absorb some colors and reflect others. Diffractive scales, diffract light, like a prism resulting in iridescent and metallic colors. And the androconia scales produce pheromones, used for communication.

On the Sinai Baton Blue, the upper side of the wings, the dorsal side, displays a vibrant blue hue, diffractive scales. The ventral side, which is the underside, of the wings presents a complex pattern of white and brown and orange markings, with a series of black spots.

Those patterns are adapted to work as camouflage in the native habitat. And the then bright reflective side can be flashed open to surprise predators, or as a showy display to attract mates.

Butterfly wings also play an important role in thermoregulation. Butterfly are cold blooded, and will close their wings to retain body heat or in the sun, open their wings to direct warming light onto their thorax. And of course, butterfly use their wings to fly. 

All butterfly wings are, of course, like totally remarkable, and for me, the Sinai Baton Blue is a special case because it is so small, the tiny details in its patterning, the striking richness of its dorsal wing coloring, that it can like fly at all. So little and so so amazing.

Okay and the third segment of the butterfly’s body, the abdomen, holds vital organs. Its digestive tract, its respiratory system and its reproductive organs. Digestive tract processes nectar and expels waste. Butterfly breathe through spiracles which are these tiny holes, mostly clustered on the abdomen, that connect to tubes that spread oxygen throughout the body.

The Sinai Baton Blue reproduces sexually, there are female butterfly and male. Those reproductive organs are clustered near the tip of the abdomen.

Sinai Baton Blues have not been observed demonstrating courtship ritual, males simply attempt to mate upon finding a willing female. Females signal unwillingness by curling their abdomen, spreading wings, or flying away. But if the female is willing, the pair position themselves in a tail-to-tail orientation, with their abdomens joining at the tips.

The male possesses a specialized organ that transfers a sperm packet (called a spermatophore) to the female. The spermatophore contains genetic information (in the sperm) and nutrients that the female can use to nourish herself and the developing eggs. After copulation, which for the Sinai Baton Blue takes about an hour, the butterfly separate and the fertilized eggs gestate for about a day within the female’s abdomen before they are laid.

Sinai Baton Blue are extremely selective when it comes to laying their eggs. They exclusively lay 20-30 eggs on the budding flower clusters of Sinai Thyme plants. That’s T H Y M E, like the herb. Just want to underline that: They only lay eggs on the flowering buds of this specific plant, the Sinai Thyme.

Scientists have also observed a preference for flower clusters that haven’t already been used by other butterfly, and the mothers also seem to assess the developmental stage of the plant favoring those with more flower clusters, just starting to bud. So, very specific needs.

The eggs typically hatch within 3-7 days, depending on environmental conditions. The newly hatched larvae are tiny, less than a 16th of an inch, with a dark brown head and pale body. They eat their way out of the egg and begin to feed on the thyme buds. Larvae have only ever been observed feeding on Sinai Thyme. And they were never observed even moving between Sinai thyme plants, they come into adulthood, through stages of growth, molting, and metamorphosis on the same individual plant they were hatched on.

Sinai Baton Blue larvae have a highly specialized symbiotic relationship with two species of local ants: L. obtusa and M. niloticum. The larvae possess two organs singularity adapted to nurturing and communication with these ant species. One is a nectary organ, which secretes sugary droplets, a reward, for the ants, and the other tentacular organ, which releases signals of alert or danger, communicating with the ants when the larvae is threatened. So the Baton Blue larvae provides food for the ants, and the ants will come when called to provide protection for the larvae when it is threatened by predators.

After about 21 days of feeding and growing on Sinai Thyme buds, the larvae descend to the base of the plant and form pupae, entering a dormant stage that lasts through the winter. They later emerge in late spring, ready for reproduction, as fully adult butterflies.

That process from slow-inching larvae to sleeping pupa to flying butterfly is totally like miraculous and we’ve already covered a lot of awe-making material with the Sinai Blue, so I’m going to save the details of that that growth and transformation process which is similar across butterfly species, for a future episode. So, for now we’re just going to go with larvae goes in – It’s autumn, it’s winter, it’s spring, butterfly comes out.

Butterfly comes out at the roots of the Sinai thyme where it hatched, will spend its adulthood feeding on the nectar from the flowers of the Sinai Thyme, spreading the plants pollen, helping the thyme reproduce, and then before the end of its short roughly 6 day adult life, the Sinai Baton Blue will reproduce, laying eggs in the same patch of Thyme where it was born.

The Sinai Baton Blue butterfly is exclusively found on the slopes of Mount Sinai, in a roughly 5 sq mile, high-altitude region of the Saint Katherine Protectorate, a National Park, in south of the Sinai Peninsula, Egypt, roughly 200 miles SE of Cairo. This is a temperate arid biome characterized by mountainous terrain with deep valleys and steep slopes, with peaks reaching over 7000 feet above sea level.

Summer temperatures reach highs in the mid 90s °F with winter lows in the teens. The region sees less than 5 inches of precipitation, annually. Though in the winters, the mountains are blanketed in snow. That snow melts seeping into the ground and providing the area with almost all its water for the dry spring, summer and autumn months.

The Sinai Baton Blue shares its habitat with Nubian Ibex, Rosemary, Field Cricket, Sinai Primrose, Rock Hyrax, Horsemint, Red Fox, Sinai Agama Lizard, Sage, Mountain Hawthorn, Golden Spiny Mouse, Wild Fig, and of course Sinai Thyme.

The major threats to the Sinai Baton Blue butterfly are not to the immediate population itself but to their singular habitat, specifically their host plant the Sinai Thyme. It’s estimated that human induced climate change will result in 3-4 degree temperature rise in this region, leading to an additional month of drought each year, a reduction of viable habitat for the Sinai Thyme and loss of available resources for the butterfly, its larvae and its symbiotic ant partners.

The Sinai Thyme is also threatened with overgrazing by domesticated livestock, goats and sheep, and by overharvesting for medicinal purposes.

Fortunately the Sinai Baton Blue’s entire, albeit small, habitat falls within the Saint Katherine Protectorate, an Egyptian national park. And in 2009 a Saint Catherine-based two-pronged conservation and education program was initiated to reach out to both itinerant shepherds and local schoolchildren. To discourage overfeeding and inspire wilderness protection in future generations.

Nevertheless, the Sinai Baton Blue butterfly was added to the IUCN red list of critically endangered species in 2010, and their population is in decline.

Our most recent counts estimate that less than 2000 Sinai Baton Blue Butterfly remain in the wild.
