Yellow-legged

November 19, 2024

Inside the front section of my local newspaper was a USA Today article on the recovery efforts for a nearly extinct frog. The High Sierra lakes in Yosemite National Park have been biologically upset for over 100 years by the stocking of non-native fish. The rainbow, golden, brown, brook, and cutthroat trout, along with Atlantic salmon and grayling, were originally carried in buckets to these fishless lakes. After World War II, a generation of pilots who were adept in aerial bombing sped up the process in all but 20% of the smallest mountain lakes. While these lakes contained no fish, they were bursting with life. Within a few years of stocking the frog populations that had flourished were gone. The National Park Service ended fish stocking in the 1990’s out of concern for the native species. In 1992, Roland Knapp, a research biologist from the University of California, Santa Barbara, got permission to use gill nets to remove the fish from a small number of lakes. The frogs began to make a comeback, but in the early 2000’s research showed the arrival of amphibian chytrid fungus. The Sierra Nevada yellow-legged frog was added to the endangered species list in 2014.

When I looked online, the Sierra Nevada yellow-legged frog (Rana sierrae), also known as the Sierra Nevada Mountain yellow-legged frog, is a true frog endemic to the Sierra Nevada of California and Nevada in the US. The yellow-legged was formerly considered the southern mountain yellow-legged frog (Rana muscosa) until a 2007 study elevated the more central and northern populations to full species status and restricting the latter to the southern Sierra Nevada and southern California. Both mountain frogs are similar in appearance but are separated by differences in mitochondrial DNA. The yellow-legged grow up to 1.5 to 3.5 inches (3.8 to 8.9 cm) long and females tend to be larger than males. The frogs have brown backs, often with dark spots or bands, and yellow legs and underbellies. Considerable variance exists in species coloration and yellow-legged frogs can also be grey, red, or greenish brown with dark splotches. Tadpoles appear black or brown and require one to four years to fully develop. These frogs hibernate during the winter, staying submerged in the mud and may only be active around three months a year depending on the weather. Studies showed 92.5% of the yellow-legged populations have gone extinct and are estimated to have declined by over 90% over their range. They are considered an endangered and vulnerable species by the IUCN.

In 2006, Yosemite National Park and the Yosemite Conservancy began a project to introduce frogs into lakes without fish. In 2007, a project was started to restore frog habitat by removing non-native fish from remote sites. Once the site is fishless, lakes are inhabited by native species, including the yellow-legged frog. The ecological effects of their loss have been significant as the yellow-legged were a keystone species and important for nutrient and energy cycling in the aquatic and terrestrial ecosystems. A 2016 survey in Yosemite indicated a sevenfold increase in their numbers reported, but recent studies discovered amphibian chytrid fungus is contributing to the decline of the Sierra yellow-legged frog. Chytrid fungus leads to a usually fatal disease (Chytridiomycosis). Chytrid fungus lives on keratin which is found on the external mouthparts of tad poles and the outer skin layer of adults. Fungus growth on adults disrupts the ability to breathe through skin (osmoregulate). The species also suffers from habitat fragmentation as populations have become separated.

THOUGHTS: Stocking fish in the High Sierra’s began as early as the California Gold Rush in 1849. The fishless lakes seemed like a waste to the miners hiking into the backwoods. Stocking fish did provide food, but it nearly destroyed the delicate habitat of the high mountains. While introducing an invasive species may seem like a good idea, it is rarely the case. Life in fragile environments is especially vulnerable. Act for all. Change is coming and it starts with you.

Siamese

November 13, 2024

Today’s MSN browser featured a report on a crocodile thought to be extinct in the wild a generation ago that is making a comeback. The animals are being bred in captivity and reintroduced to their natural habitat. The conservation effort began in 2012 and last June the crocodiles laid 106 eggs and produced 60 hatchlings. There are about 1,000 of the crocodiles in the wild, including 400 in Cambodia. The species was nearly killed off by habitat destruction, poaching, and crossbreeding. Ironically, the hunters who captured, bred, and killed the crocodiles to sell their skins helped them bounce back. These captured crocs are the source of purebred, fertile crocodiles that were pulled from a population of 1.5 million (mostly hybrids) being bred for leather. After the females lay eggs, the eggs are incubated at the Phnom Tamao Wildlife Rescue Centre, allowing the crocodiles to develop before they are brought to a national park in the Cardamom Mountains. According to Pablo Sinovas of Fauna & Flora, only one in 20 crocodiles born in the wild survives, but if they are bred captively and not released until they reach 1 meter in length, “their chances of survival increase exponentially.”

When I looked online, I found the Siamese crocodile (Crocodylus siamensis), also known as the Singapore small-grain and soft-belly crocodile, is a medium-sized freshwater crocodile native to Indonesia (Borneo and possibly Java), Brunei, East Malaysia, Laos, Cambodia, Myanmar, Thailand, and Vietnam. The animal is medium-sized, with a relatively broad, smooth snout and an elevated, bony crest behind each eye. It is generally olive green but can range to a dark green. Immature crocodiles measure 4 to 5 feet (1.2 to 1.5 m) and weigh from 13 to 26 pounds (6 to 12 kg). Adults can grow to a length of 7 to 10 feet (2.1 to 3 m) and weigh from 88 to 265 pounds (40 to 120 kg). Adults have a bite force of 466 to 1,029 pounds per foot (2,073 to 4,577 N). Large males can reach over 13 feet (4 m) and weigh 770 pounds (350 kg). The species is critically endangered and already extinct in many regions.

The Siamese crocodile is critically endangered on the International Union for Conservation of Nature (IUCN) Red List and is listed on Appendix I of Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). In Cambodia, Fauna and Flora International and the Government of Cambodia’s Forestry Administration have established the Cambodian Crocodile Conservation Programme for the protection and recovery of Siamese crocodiles. This program works with a network of indigenous villages who are helping to protect key sites such as Veal Veng Marsh (Veal Veng District), the Tatai River (Thmar Bang District), and the Araeng River. The Araeng is thought to have the second largest population of Siamese crocodiles in the world but is being threatened by proposed construction of a massive dam. The Siamese take advantage of the increase in water levels during the Monsoon season (June to November) to move out of the river and onto large lakes and other local bodies of water, returning to their original habitat once water levels receding back to their usual levels. Since 2012, approximately 50 purebred Siamese crocodiles have been released into community-protected areas to reinforce the depleted wild populations.

THOUGHTS: Conservationists are also trying to protect Siamese crocodile’s habitat as 32% of the Cambodia’s tree cover was lost from 2001 to 2023 due to climate change and deforestation. Sean Pang stated, “Policymakers must recognize that addressing both climate and land use change is crucial for protecting the fate of South-east Asia’s trees, and likely for much of the region’s biodiversity.” The world’s natural resources are at peril without a combined effort by government, conservationist, and the local population. Act for all. Change is coming and it starts with you.

Mud Tracks

November 06, 2024

We have received heavy rain over the last two days, and I tried to keep the kids out of the side yard. I monitor them when I do let them out to make sure they are not mischievous (Loki is a digger and Zena is a roller) and end up covered in mud. Today the rain stopped, and I decided to brave our walk site at the lake. A portion of the walk is on a paved parking lot, but the majority covers packed dirt tracks that lead out to the end of two spits. We were the only ones there when we arrived to begin our walk. We walked to the end of the first spit and while it was wet, we were able to pick our way through the puddles without getting our paws muddy. As we were coming off the spit two 4-wheel drive pickups pulled out onto the other spit and began to cut mud tracks through the vegetation. As we walked around the paved lot on the trail the trucks moved to the area we had just left. This had a wider area that had been torn up by previous off-road activity. It did not take long for one of the trucks to get stuck axel deep in the mud. This was obviously why they had come in the first place. After extricating the truck, they drove to the boat ramp and took selfies of the mud covered truck to share with their friends. Teenagers in pickups are not the only ones that leave mud tracks.

When I looked online, I found one of the more famous mud tracks is located at Racetrack Playa in Death Valley. Racetrack playa is approximately 3 miles (4.8 km) long and 1.2 miles (1.9 km) wide and is located at a height of 3708 feet in a north-south valley east of the Panamint Range within Death Valley National Park. The playa receives only 3 inches of annual precipitation and is bounded on all sides by north-south ranges rising 1500 to 2000 feet (457 to 610 m). The surface of the playa is mainly dried clay and provides a hard, smooth, and level pavement. The sailing stones, also called sliding or walking rocks, move and inscribe long tracks along a smooth valley floor without animal intervention. The movement of the rocks occurs when large, thin sheets of ice floating on a brief winter pond break up in the sun. Rocks weighing up to 705.5 pounds (320 kg) travel across the playa and leave mud tracks. Stones with rough bottoms leave straight striated tracks, while those with smooth bottoms tend to wander. The mud trails differ in both direction and length. Rocks that start next to each other may travel parallel for a time and then one abruptly changes direction to the left, right, or even back to the direction from which it came. This phenomenon has been documented since 1948 and is not unique to Racetrack Playa. Tracks in the mud have been observed around the world.

Traditionally, these rocks were considered to be pushed by wind over a wet and slippery playa surface but observations from 2014 called this assumption into question and several aspects of the mud tracks remain a mystery. A thorough system was put up to investigate the rock movement that included a weather station near the playa, time-lapse cameras centered on the southeast corner, and 15 GPS-equipped boulders on the surface. The researchers went to the location for maintenance and data retrieval 5-8 times per year and from November to March of each year the time-lapse camera recorded hourly conditions. Interwoof GPS loggers were also installed in limestone blocks northeast of natural stones and captured GPS and temperature data every 60 minutes. The GPS trackers began recording constantly at one-second intervals after being triggered. The shape of the shallow lake named Ontario Lacus on Saturn’s moon Titan has been compared to that of Racetrack Playa.

THOUGHTS: Despite the signs and barriers forbidding driving on the surface and making mud tracks posted along parts of the playa, park rangers still find new tire tracks on it every couple of years. The walking rocks will not slide if the surface is defaced. Destruction of such natural wonders takes decades to repair. Act for all. Change is coming and it starts with you.

House Finch

November 05, 2024

Melissa received a window box bird feeder as a gift from our son and family earlier this year. The feeder has suction cups on the back that allow it to attach directly to the glass. I placed the feeder in the bay window in the breakfast nook that serves as her home office so she can enjoy the bird activity while working. I fill the two sections of the feeder with different seeds to make it more attractive to the small birds willing to approach the window. One side has always had black sunflower seed (Helianthus annuus). I have varied the seed on the other side, but it currently has cracked safflower seed (Carthamus tinctorius). This feeder has become a preference for the eastern bluebirds (Sialia sialis), the sparrows (Genus, Zonotrichia), and purple finches (Haemorhous purpureus) that frequent our back yard. On Sunday I noticed what seemed to be a new species at the feeder. This was similar to the finches I have been watching but somehow seemed different. When I checked my bird ID this turned out to be a house finch.

When I looked online, I found the house finch (Haemorhous mexicanus) is a North American bird in the finch family. The species is native to Mexico and southwestern US but has been introduced to the eastern part of North America and Hawaii and is now found year-round throughout the US and most of Mexico. The house finch is a moderate-sized bird at 5 to 6 inches (12.5 to 15 cm) long, with a wingspan of 8 to 10 inches (20 to 25 cm). Body mass can vary from 9⁄16 to 15⁄16 ounces (16 to 27 g) with an average weight of 3⁄4 ounces (21 g). Adults have a long, square-tipped brown tail and are a brown or dull-brown color across the back with some shading into deep gray on the wing feathers. Breast and belly feathers may be streaked, and the flanks usually are. Most adult males have reddish heads, necks, and shoulders, and the color can extend to the belly and down the back as well. Male coloration varies in intensity with the seasons as it is derived from a diet of berries and fruits. Adult females have brown upperparts and streaked underparts. There are around 40 million house finches across North America, making it the second-most populous finch behind the American goldfinch.

The house finch and purple finch are closely related species and can be hard to identify. The main difference between the two species is the amount of red on the bird and the pattern on the face. They have similar body shapes, but the bill of the purple finch is a bit bigger, more conical, and deeper, while that of the House Finch has a more rounded shape. Both species get along with other small birds except during breeding season when they become protective of their territory. The other big difference comes with habitat. The house finch prefers a wide range of arid, open, and semi-open habitats, and will live in oak-juniper woodlands, open coniferous forests, and shrubby, and desert habitats from sea level to more than 11,000 feet, the house finch avoids dense forest of the purple finch. A small flock of house finch in Long Island, NY, escaped captivity in 1939 and has become the common bird of the eastern US and southern Canada. Their population has grown and expanded to millions of birds that thrive in urban and suburban places, preferring parks and urban settings with conifers and ornamental trees. Their songs are similar, but the purple finch sings a more melodious and “warbling” song, while the house finch incorporates chattering and trilled sounds.

THOUGHTS: Another similarity between the house finch and purple finch is they are both attracted to bird feeders. This explains why I have seen both species (and probably not realized it until now) in our backyard. Neither species is rare, but the house seems more urban and the purple more forest. Nature tells us that when the same species spend enough time separated and/or refusing to interact they grow apart and eventually become distinct. While humans have not yet reached that point as a species, it is a good lesson to be learned. Act for all. Change is coming and it starts with you.

Beetle

October 30, 2024

Hidden in the back of the front section in yesterday’s newspaper was a USA Today article about Hawaii’s attempts to stop an invasive insect.  According to the Hawaii Invasive Species Council, the invader “jeopardizes the economy, the entire ecosystem, agriculture and food security.”  This species feeds by biting and boring into emerging palm fronds, creating holes in the top of the tree.  While they prefer to feed on coconut, royal, date, and fan palms, they will also feed on hala, taro, banana, pineapple, and sugarcane if the palm trees are unavailable.  The insects are nocturnal and can fly up to two miles if they are looking for food.  The insect attacks a palm at the base of the fronds (leaves) where they are attached to the trunk, bore through the base of the fronds into the center of the crown (the palm heart), and feed on the undeveloped white fronds.  Attacks cause a reduction in leaf area on the damaged fronds and results in a reduction in the number of nuts produced.  Newly planted palms can have their growth point destroyed resulting in the palms death and even mature palms may die after extremely heavy attacks by the coconut rhinoceros beetle.

When I looked online, I found the coconut rhinoceros beetle (Oryctes rhinoceros), also known as Asiatic rhinoceros beetle, is a large species of beetle belonging to the subfamily Dynastinae.  This dynastid beetle has a length of 1.4 to 2 inches (3.5 to 5 cm) and is a dark brown to black color.  The head has a horn which is more prominently developed in males and in larger specimens. The first segment of the thorax (pronotum) has a large central depression with two humps at the hind margin and the tibia of the foreleg has three large teeth.  Male beetles can be reliably distinguished from females as the tip of the abdomen is rounded, shiny, and hairless.  In females the tip is more pointed and densely covered with hair.  The larvae are C-shaped white grubs typical of other scarab beetles.  The beetle breeds in decaying palm trunks or other organic matter (sawdust or compost heaps).  The native distribution of this beetle covers most parts of tropical Asia, but human activity accidentally introduced the beetle to a large number of tropical islands throughout the Pacific.   The beetle has most recently invaded Guam, Hawaii, the Solomon Islands, and Vanuatu.

A virus disease of coconut rhinoceros beetle (Oryctes rhinoceros nudivirus) has turned out to be the most effective natural control agent.  This virus was discovered by Alois Huger in Malaysia in 1963 and was later found to occur naturally in other countries within the native range of the beetle.  The introduced beetle populations in the Pacific and in the Maldives were found to be virus-free.  The virus was introduced into the virus-free populations and caused a significant decline in the beetle population.  The virus mainly effects the adult population and spreads easily, reducing their life span and the fertility of females.  During replanting of palms more breeding sites become available and transmission of the virus is often interrupted, and outbreaks still occur.  There is also evidence of resistance to the virus in some coconut rhinoceros beetle populations.  A fungus (Metarhizium majus) is also effective in controlling the beetles in breeding sites, but it does not spread well by itself.  The fungus does have the advantage that it survives for some time outside its host (as conidia).

THOUGHTS: Use of a virus to control the coconut rhinoceros beetle population is common, and natural biological controls include predators, parasitoids, pathogens, and competitors.  Biological control can have side-effects on biodiversity through attacks on non-target species by any of these mechanisms, especially when a new species is introduced without an understanding of the possible consequences.  Viruses being transmitted to other species (and humans) may cause greater harm than the original problem.  Alexander Pope’s proverbial phrase in 1711 was, “To err is human”.  Even without forgiveness, this is more than an adage.  Act for all.  Change is coming and it starts with you.

Tiger Moth

October 22, 2024

Our enclosed porch serves as a greenhouse for both Melissa’s succulents and a rack during late winter for my vegetable seedlings.  The area is also used to store Melissa’s supplies and the seeds I use to feed the birds.  When I started feeding birds several years ago, I set the bags on the floor.  This worked for several months, but as the weather got colder the rodents that thrived in the tall grass of the lot behind our house were more intent on seeking food and shelter.  While I never saw a house mouse (Mus musculus) or brown rat (Rattus norvegicus), I did have several instances of “something” chewing through the seed bags and spilling the contents onto the floor.  I now have a large 20 gallon (76 l) tub for the larger bags and 3 smaller 5 gallon (15 l) buckets to hold the daily dispersal.  The containers are large enough to contain the seed and have a lid which keeps out the (hopefully) mice.  While cleaning behind the “supplies” behind the feed buckets I found more evidence of mice, but again no actual critters.  What I did find beneath several of the buckets was a brightly colored moth.  When I checked my phone identification it said this was a harnessed tiger moth.

When I looked online, I found the harnessed tiger moth (Apantesis phalerata) is a species of moth within the Erebidae family, first described by Thaddeus William Harris in 1841.  The harnessed tiger moth’s subfamily (Arctiinae) has about 11,000 species of tiger moths divided globally across three tribes.  The harnessed tiger moth is indigenous to North America, with a geographical distribution from Ontario, Quebec, and Maine in the north, to the west in South Dakota, and stretching south to Florida and Texas.  The adult moth has a wingspan ranging from 1.2 to 1.7 inches (30 to 42 mm), and their distinctive black and orange wing patterns earned them the name “tiger” moth.  The tiger moth has a grooved exoskeletal structure (tymbals) on the posterior three segments of the thorax (metathorax) which they use to produce high frequency cicada (superfamily, Cicadoidea) like clicks.  The clicks are a defensive mechanism against predation and for communication during mating.  The lifespan of a harnessed tiger moth ranges from 5 to 10 days after mating.  The moth’s activity period varies regionally, being active from April to September in the southern parts of its range, and from May to August in the northern areas.  My tiger moth was active (at least alive) in mid-October. 

The harnessed tiger moth uses its vibrant colors to serve as a visual deterrent, signaling to potential predators that they are distasteful.  Despite their warning colors, harnessed tiger moths are preyed upon by bats, which rely on echolocation (not sight) to hunt.  This tiger moth is not poisonous, but adults do secrete a liquid to ward off predators that can cause allergic reactions in humans.  The furry body of the caterpillar can also cause rashes and irritation if touched with bare hands.  There are many spiritual meanings attached to the various species of tiger moth and different types of tiger moths hold different gravity in various cultures worldwide.  White-colored tiger moths are seen as a sign of peace and innocence as white is often considered the color of peace. 

THOUGHTS: Two common spiritual meanings are attached to all tiger moth species around their attraction to light.  Some believe spotting a tiger moth is an indication that the person must leave the dark and start embracing the light in their soul.  For other cultures this is a warning that means not to be easily lured by charming deals or things and think rationally before making decisions.  Human decisions are fraught with a similar dichotomy of good and bad.  Roman Emperor Marcus Aurelius, in his Meditations said, “You have power over your mind – not outside events.”  Nietzsche takes the same perspective, affirming the agency of the individual goes beyond good and evil and declares what is “good” and “bad” by what is serving and hindering their own goals.  There are not absolutes, only your reaction to events.  Act for all.  Change is coming and it starts with you.

Habitat

October 03, 2024

Melissa and I have been trying to revamp the furniture in our living room since the day we moved into her house in Arkansas.  Knowing we had a house full of furniture in Arkansas, we donated most of our furniture to the Conference Center where I had been working.  While our Kansas furniture was in good shape, it was the first furniture I purchased 20 years earlier and I was ready for a change.  When we moved to Arkansas the furniture was not much newer and was a style neither of us liked.  We tried buying an inexpensive living room set two years ago, but it turned out to be inexpensive.  Over the weekend Melissa visited a friend in northwest Arkansas and was impressed with the style and utility of the furniture she had.  Needless to say, we went shopping over the weekend and came away with a sofa and chair as a replacement.  That left one question, what are we going to do with the items we no longer need?  We decided on repurpose by donating to Habitat for Humanity.

When I looked online, I found Habitat for Humanity International, also referred to as Habitat for Humanity or Habitat, is a US non-governmental, and tax-exempt 501(C)(3) Christian nonprofit which seeks to build affordable housing.  It was founded in 1976 by Millard and Linda Fuller.  The operational headquarters are located in Americus, Georgia, and the administrative headquarters are located in Atlanta.  In 2023, Habitat for Humanity operated in more than 70 countries and works to help build and improve homes for low-income or disadvantaged families.  Homes are built using volunteer labor, including the practice of sweat equity from the future homeowners, along with paid contractors for certain construction or infrastructure activities.  Habitat makes no profit from the home sales and instead operates with financial support from individuals, philanthropic foundations, corporations, government entities, and mass media companies.  While Melissa and I have worked on several houses, it is probably better known that President Jimmy Carter and Rosaland worked many more volunteer hours building Habitat houses.

Along with building houses, Habitat ReStores accept small and large donations of new or gently used furniture, appliances, housewares, and building materials.  The sale proceeds then help Habitat’s work in the local community and around the world.  Items can be donated in person, and many Habitat ReStores offer free pickup of large items.  We were able to donate 2 sofas, 1 recliner, and a love seat to our local ReStore.  I made an appointment, and they picked up the items this morning.  Unfortunately, 1 recliner did not make the cut (worn).  The EPA estimates that 9 million tons of furniture are tossed every single year, or roughly 5% of everything brought to landfills.  Most of the furniture going to the land fill was made within the last 10 to 15 years, according to Ashlee Piper, sustainability expert and author.  Part of the problem is that today’s fast furniture is more challenging to repair because of its materials.  Unlike grandma’s, these pieces are not meant to last a lifetime.

THOUGHTS:  While in Berkeley I was living across the street from the Cal dorms.  The students obviously did not know about Habitat and each spring term as they were kicked out for the summer their fast furniture ended up in my building’s dumpster, allowing me to upgrade every year.  The price or where the item of furniture was made can be a red flag for new items.  Shopping locally can increase your odds of something being made with a thoughtful production process, rather than something where the emphasis is put on producing goods as cheaply as possible.  There are often good finds in secondhand stores (like Habitat) that with some minor repairs or refurbishing will make the piece feel fresh.  We are not all blessed with an overflowing dumpster.  Act for all.  Change is coming and it starts with you.

Sea Robins

September 30, 2024

David Kingsley, the Rudy J. and Daphne Donohue Munzer Professor in the department of developmental biology at Stanford University’s School of Medicine, first came across an odd looking fish in 2016 when he stopped into a small public aquarium in Woods Hole, Massachusetts.  “The fish on display completely spun my head around because they had the body of a fish, the wings of a bird, and multiple legs like a crab,” Kingsley said.  Kingsley and his colleagues decided to study the fish in the lab and found differences between the sea robin species and the genetics responsible for their unusual traits.  The findings of the study team’s new research show how evolution leads to complex adaptations in specific environments, such as the ability of sea robins to be able to “taste” prey using their highly sensitive appendages.  According to their research, some types of the bottom-dwelling ocean fish use taste bud-covered legs to sense and dig up prey along the seafloor.  Sea robins are so adept at rooting out prey on the ocean floor with their leglike appendages that other fish follow them around hoping to snag some of the freshly uncovered prey themselves.

When I looked online, I found sea robins (order, Triglidae), commonly known as gurnards, are a family of bottom-feeding scorpaeniform ray-finned fish.  Triglidae is one of the five largest orders of bony fishes and is divided into 3 subfamilies and 8 genera that include 125 species distributed in temperate and tropical seas worldwide.  Most species are around 12 to 16 inches (30 to 40 cm) in length with the females typically being larger than the males.  They have an unusually solid skull, and many species possess armored plates on their bodies.  Another distinctive feature is the presence of a “drumming muscle” that makes sounds by beating against the swim bladder.  Sea robins have three “walking rays” on each side of their body that are derived from the supportive structures in the pectoral fins (fin-rays).  During development, the fin-rays separate from the rest of the pectoral fin and develop into walking rays.  These walking rays have specialized muscle divisions and unique anatomy that differ from typical fin-rays to allow them to be used as supportive structures during underwater locomotion.  The rays are used for locomotion and prey detection on the seafloor via tasting (chemoreception) and are highly sensitive to the amino acids in marine invertebrates.

While all sea robins have leglike appendages, only some have the macroscopic sensory organs that allow them to taste the environment.  Research revealed digging sea robins depend on a regulatory gene called tbx3a not only to develop their specialized fin adaptations but also to form the papillae that cause them to dig. Tbx3 also plays a role in limb development in humans, chickens, mice, and other fish species.  The fish grew legs using the same genes that contribute to the growth of our limbs and then repurposed these legs to find prey using the same genes our tongues use to taste food.  Sea robins stand out among other walking fishes because their pectoral fins (walking fin rays) are highly jointed and their skeletal and muscular anatomy showcase unique modifications that enable the sea robins to walk. 

THOUGHTS:  Sea robins have firm white flesh that holds together in cooking, making them well-suited to soups and stews such as the French bouillabaisse.  They were often caught in British waters as a bycatch and discarded, but as other species became less sustainable and more expensive, they became more popular.  Sea robins (gurnards) are used as bait by lobster fishers but are also now appearing in fish markets in the US.  As desirable species are overfished or become scarce humans turn to the “next one up” to meet our food needs.  We need to find ways to make fishing sustainable, or even the rough (trash) fish will be in short supply.  Act for all.  Change is coming and it starts with you.

Moo Deng

September 28, 2024

Moo Deng is a pygmy hippopotamus living in Khao Kheow Open Zoo in Si Racha, Chonburi province, Thailand, born on 10 July 2024.  Her name was chosen through a public poll with over 20,000 people voting for “Moo Deng”, translating to “bouncy pig”.  The zoo posted images of her on its Facebook page and Moo Deng quickly became a fan favorite for her playful and energetic romps.  Her popularity led the zoo to sell clothing and other merchandise featuring designs based on her likeness.  Other companies produced merchandise, including a cake shop (Vetmon Café) which created a realistic cake shaped like her.  Moo Deng’s viral popularity resulted in a doubling of daily visitors in early September.  The zoo is in the process of copyrighting and trademarking “Moo Deng the hippo” to raise funds for the zoo and plans to launch a livestream to allow fans to watch Moo Deng over the Internet.

When I looked online, I found Moo Deng is a pygmy hippopotamus (Choeropsis liberiensis) or pygmy hippo, a small hippopotamid native to the forests and swamps of West Africa.  The pygmy is one of only two extant species in the family Hippopotamidae, the other being the larger common or Nile hippopotamus (Hippopotamus amphibius).  The pygmy hippo was unknown outside West Africa until the 19th century and is a reclusive and nocturnal forest creature difficult to study in the wild.  Like the common hippo, the pygmy hippo displays terrestrial adaptations but is semiaquatic and relies on water to keep its skin moist and its body temperature cool.  Mating and birth may occur in water or on land.  The pygmy is herbivorous and feeds on ferns, broad-leaved plants, grasses, and fruits it finds in the forests.  Current pygmy populations are primarily in Liberia, with small groups in Sierra Leone, Guinea, and Ivory Coast.  It has been extirpated (eradicated) from Nigeria.  Pygmy hippos are primarily threatened by loss of habitat, as forests are logged and converted to farmland.  The Pygmy are also vulnerable to poaching, hunting for bushmeat, natural predators, war, and are illegally hunted for food in Liberia.  The species breed well in captivity and the vast majority of research is derived from zoo specimens.  A 2015 assessment by the International Union for Conservation of Nature estimated that fewer than 2,500 pygmy hippos remain in the wild.

As a viral sensation Moo Deng has prompted a makeup trend popular with beauty influencers.  Moo Deng makeup is in line with what beauty enthusiasts look for, super dewy skin and lots of blush.  The trend is perfect for fall as the skin will be hydrated and glass-like as the drier months approach.  The trend started with influencers trying to recreate her iconic look by achieving the baby pygmy’s glass-like skin with the prettiest shade of blush.  Before applying makeup, you need to ensure the base is nice and dewy to capture the baby hippo’s glistening skin.  The trend incorporates lots of grey hues to represent Moo Deng’s skin color.  An element common among influencers’ is the heavily flushed cheeks.  Any blush shade will do, as long as it has a great color payoff.  Grey eyeshadow or lip gloss, followed by a particular shade of blush create the final makeup look.

THOUGHTS:  While Moo Deng may create viral views, sales, and makeup, she is at risk.  Some visitors harassed Moo Deng by splashing her with water and throwing objects to wake her up, forcing the zoo to install security cameras around her enclosure.  The zoo also implemented a 5-minute time limit for visitors to accommodate the high volume of visitors.  While most marvel at the wonder of nature, there are others who find pleasure in destruction.  Whether it is throwing objects at Moo Deng or toppling 100,000 year old rock formations the seconds of fame being sought are not worth the cost.  “Influence” comes with responsibility.  Act for all.  Change is coming and it starts with you.

Euphorbia Ingens

September 27, 2024

Melissa was working on her succulents over the weekend and called me out to see what was going on with her plants.  We had placed two tables in the flower bed on the north side of the house that we have yet to figure out what to do with.  Melissa decided in the short run this would be a good place to put some of her hardier cacti to take advantage of the outside.  Although these plants are visible through the porch windows, Melissa does not get out to physically check on them more than once a week.  As with most cacti and succulents, a good rule of thumb is to leave them alone and let them thrive on their own.  One of the plants has been growing particularly well over the last two years and is over 3 feet (1 m) tall.  The third section of the plant had developed greenish-yellow buds along its ridges which appeared to be ready to bloom.  When I asked, she told me this was a Euphorbia ingens (I sometimes think she uses the scientific names just to throw me off).   

When I looked online, I found the candelabra tree (Euphorbia ingens), or naboom, is a species of flowering plant in the family Euphorbiaceae native to dry and semi-savanna areas of southern Africa.  This tree is a tall succulent with green round-like branches resembling a balloon that grows to 19.5 to 26 feet (6 to 8m) tall.  The trunk of the candelabra is thick, and the stems have 5 ridges each and are 1-1/3 to 3 inches (3.5 to 7.5 cm) thick.  The segmented stems are dark-green and young sprouts have paired spines 3/16 to 5/64 inches (0.5 to 2 mm) long.  The plant blooms from autumn to winter and the small greenish yellow flowers sit on the ridges of the topmost segment.  A red, round, three-lobed capsule fruit turns purple when ripe.  The plant’s flowers are attractive for butterflies, bees and other insects, which pollinate them when gathering pollen and nectar.  The seeds are edible for birds, who also like to make their nests in the branches of these trees.  The light and solid wood of the main trunk is used in door, plank, and boat production.  The milky latex sap of the tree is highly poisonous and can cause blindness, severe skin irritation, and poisoning (when ingested) in humans and other animals.  The plant has few pests due to the toxic sap.

Euphorbia ingens grows well both indoors and outdoors and has become a popular choice for rock gardens and indoor houseplant collections due to its stately appearance and low maintenance.  In their natural environment, these succulents can grow up to 40 feet (12 m) tall, but they usually top out around 8 to 10 feet (2.5 to 3 m) tall when grown indoors.  Still, even this would take a high ceiling to accommodate a mature plant.  When grown indoors or in containers, it is extremely uncommon for this species of euphorbia to produce blooms.  Since Melissa’s plant has budded, we are waiting to see if it will break into full bloom.

THOUGHTS:  The buds on the Euphorbia ingens are only the latest of Melissa’s accomplishments.  Over the last two years she has repeatedly shown me the flowers that have bloomed on many of the succulents and cacti that are under her care.  In my case, with the exception of the ground cherry (Physalis angulate) that I did not plant and the red burgundy okra (Abelmoschus esculentus) I do not like to eat, I have often struggled with production of my plants (pole beans are another exception).  Melissa’s mom was a prolific gardener whose secret was to spend hours tending her flowers.  The same it true with Melissa who spends hours with her succulents.  I am willing to plant, water, and harvest.  Perhaps there is a lesson there.  When we are willing to put in the work, we can achieve most tasks.  That is true for gardening.  That is also true for creating positive human interaction.  Do the work.  Act for all.  Change is coming and it starts with you.
