Losing a large number of individuals is a tragedy, but what happens when we lose an entire whale culture? What do we lose when we lose a way of life? Every culture, whale or otherwise, is its own solution to the problems of the environment in which it lives. With its extirpation, we lose the traditional knowledge of what it means to be a Caribbean whale and how to exploit the deep sea riches around the islands efficiently. And that cannot be recovered.
From deities to data - "For thousands of years humans believed that authority came from the gods. Then, during the modern era, humanism gradually shifted authority from deities to people... Now, a fresh shift is taking place. Just as divine authority was legitimised by religious mythologies, and human authority was legitimised by humanist ideologies, so high-tech gurus and Silicon Valley prophets are creating a new universal narrative that legitimises the authority of algorithms and Big Data."

The moment I realize I have skunks living in my yard, I become obsessed with them. Within a few weeks, I have the skunk skull on my desk, a stack of articles on skunks, and a copy of The Biology of the Striped Skunk, by B. J. Verts—the definitive textbook on the animal, published in 1967. (In fact, it’s the only textbook on the striped skunk.) I’m waiting for a bottle of skunk essence to arrive in the mail...[more inside]

In his follow-up to Sapiens, Yuval Noah Harari envisions what a 'useless class' of humans might look like as AI advances and spreads - "I'm aware that these kinds of forecasts have been around for at least 200 years, from the beginning of the Industrial Revolution, and they never came true so far. It's basically the boy who cried wolf, but in the original story of the boy who cried wolf, in the end, the wolf actually comes, and I think that is true this time." [more inside]
"While crows and ravens get most of the attention, smaller members of the corvid family like jays and nutcrackers are out in the world busily building and rebuilding forests. Not on purpose, of course, but through a behavior charmingly called “scatter hoarding,” which basically involves stashing seeds around in various places for later devourment." And this allows the trees - oaks, chestnuts, beeches, hickories - to "borrow the wings of birds." [more inside]
"When Hadza want to find honey, they shout and whistle a special tune. If a honeyguide is around, it’ll fly into the camp, chattering and fanning out its feathers. The Hadza, now on the hunt, chase it, grabbing their axes and torches and shouting “Wait!” They follow the honeyguide until it lands near its payload spot, pinpoint the correct tree, smoke out the bees, hack it open, and free the sweet combs from the nest. The honeyguide stays and watches. It’s one of those stories that sounds like a fable—until you get to the end, where the lesson normally goes. Then it becomes a bit more confusing."

"Don't look at them directly,” Rie Henriksen whispers, “otherwise they get suspicious.” The neuroscientist is referring to a dozen or so chickens loitering just a few metres away in the car park of a scenic observation point for Opaekaa Falls on the island of Kauai, Hawaii. As the two try to act casual by their rented car, a jet-black hen with splashes of iridescent green feathers pecks its way along a trail of bird feed up to a device called a goal trap. Wright tugs at a string looped around his big toe and a spring-loaded net snaps over the bird. After a moment of stunned silence, the hen erupts into squawking fury. Biologists see in the feral animals an improbable experiment in evolution: what happens when chickens go wild?[more inside]
The whale is so big, the frogs are so bright, the Hall of Biodiversity an astonishing swarm of life. The planetarium space show tells a story, but it holds your attention by engulfing your senses with an experience. And then maybe this excitement inspires a little girl to go home and learn the names of the constellations and all the planets and their moons, and the night sky is no longer spooky darkness, but a beautiful realm full of things she can name. The museum today teaches you about science, but it makes you care by getting you to fall in love.
Argentine ants altering California's ecosystems as homeowners give them shelter The Kentucky woman found herself waging war on a freezer full of Argentine ants. Thousands of them had set up shop inside the appliance's insulation, and a steady stream of tiny bodies poured out of the cracks to forage in the kitchen. "There was a fortress within the freezer walls," said Cliggett, who set out baits but still spent nearly an hour a day wiping up the fallen soldiers' carcasses.
Jack Gilbert, a Microbial Ecologist at Argonne and an Assistant Professor in the Department of Ecology and Evolution at the University of Chicago, gave a free public lecture at Argonne. In recent years, scientists have discovered that our bodies teem with microbial life, which outnumber our cells 10 to one. In his talk, Gilbert explored how your microbial world influences your health, probing where that microbial world comes from, and highlighting the ways in which your lifestyle, diet and medical treatment can influence your microbiome.
GrowUp: the future of food - "The new concept of commercial aquaponics, argue Hofman and Webster, has a much-reduced environmental impact. Companion farming fish and crops dates back to the Aztecs, but it took until the 2010s, in Chicago, to move it indoors at any scale. In the UK, only eco-smallholdings have so far attempted it, and the only European aquaponics farms of note use purpose-built greenhouses. GrowUp's model, by contrast, is to fit out empty urban buildings, use no chemicals, employ LED lights, source 100 per cent renewable energy and, crucially, be based within five miles of its customer base in a dense urban area."

The world's coral is suddenly and rapidly starting to die - "This is only the third time we've seen what we would refer to as a global bleaching event. [The prior events] were in 1998 and 2010, and those were pretty much one year events. We're looking at a similar spatial scale of bleaching across the globe, but spanning across at least 2 years. So that means a lot of these corals are being put under really prolonged stress, or are being hit 2 years in a row." Can 'manually breeding supercorals capable of living in increasingly inhospitable waters' help in time? (via/via)

Why Poor Places Are More Diverse : a lesson from ecosystem ecology.
According to Wired, "Paired with AI and VR, Google Earth will change the world". But just after its tenth birthday, Google Earth is already changing the world even without AI or VR, simply by giving scientists tools to map the world's problems (NYT). Google Earth Engine has become an emerging tool in environmental monitoring, conservation, water resources, regional planning, epidemiology, forestry, agriculture, climate science, and many other fields:
In 2007, not long after taking the job at Google, Askay flew to Brazil, helping an indigenous tribe, the Surui, map deforestation in their area of the Amazon, and this gave rise to a wider project called Google Earth Engine. With Earth Engine, outside developers and companies [and scientists] can use Google’s enormous network of data centers to run sweeping calculations on the company’s satellite imagery and other environmental data, a digital catalog that dates back more than 40 years.[more inside]
Raimondi had recently found himself undergoing an unexpected and not entirely desirable career shift: He had been thrust into the role of sea star detective. Though he is a marine biologist who divides his time between analyzing data and conducting research trips along the Pacific Coast, Raimondi is not entirely ill suited to the part. There is a private-investigator quality to his round, inquiring face, active eyes, and urgent, impatient voice.
It's common to frame ecology as a science that gets practiced in wild, untraveled areas. But cities have an ecology all their own, and the design of a given city contributes to the diversity of animals that make their homes there. Rats are particularly good at navigating cities, but other species might have a tougher time getting around.
The Flow Hive, the 12 million dollar Indiegogo campaign is a brand new way of keeping bees. But did we need a brand new way? And if we did, is this the right one?

Chris Crowe has a girlfriend. She stands a leggy 5 feet tall, weighs a trim 11 pounds, and sports a set of wings like you’ve never seen. Walnut the white-naped crane is the most genetically distinct endangered crane on the block — which means she needs to have been making babies, like, yesterday. Walnut was raised by humans at a zoo, and as a result, she recognizes and trusts humans — and is deeply hostile to other cranes. How hostile? She killed the two male cranes that her former keepers attempted to pair with her. "I like to jokingly tell people that Walnut ‘allegedly’ killed two male cranes," Crowe says. "It’s not like she was tried and convicted. We don’t know her side of the story."
"In July 1960, Jane Goodall boarded a boat, and after a few hours motoring over the warm, deep waters of Lake Tanganyika, she stepped onto the pebbly beach at Gombe. Last summer, almost exactly 54 years later, Jane Goodall was standing on the same beach. The vast lake was still warm, the beach beneath her clear plastic sandals still pebbly. But nearly everything else in sight was different."
If other horses are the equivalent of feral dogs, then the Przewalski’s horse is a wolf. In its native Mongolia, where it goes by the name takhi, it is known as the father of horses. Mongolians regard the takhi as spiritual, holy animals, and for millennia they largely left them alone... The trouble all began in the late 19th century, when the Western world finally took note of the takhi. Nikolai Przewalski, a Polish-born explorer serving as a colonel in the Russian army, “discovered” the horses during an 1878 expedition to the Mongolian-Chinese frontier. Naturally, Przewalski named the horse after himself, and when he returned to the West, word quickly spread among zoos, adventurers, and curio collectors about the mysterious wild horses.

That's right - it's time for Mammal March Madness! "Battle outcome is a function of the two species' attributes within the battle environment. Attributes considered in calculating battle outcome include temperament, weaponry, armor, body mass, fight style, and other fun facts that are relevant to the outcome. These are one on one- head to head combat situations- um except for the mythical mammals that have multiple heads. Some random error has been introduced into calculating battle outcome & the amount of that error is scaled to the disparity in rankings between combatants. Early rounds, the battle occurs in the better-ranked species' habitat (home court advantage). BUT once we get to the ELITE EIGHT, battle location will be random: forest, semi-arid desert, intertidal zone, or snowy tundra."

In this paper, we examine a first-year torque and angular acceleration problem to address a possible use of the forelimbs of Tyrannosaurus rex. A 1/40th-scale model is brought to the classroom to introduce the students to the quandary: given that the forelimbs of T. rex were too short to reach its mouth, what function did the forelimbs serve? This issue crosses several scientific disciplines including paleontology, ecology, and physics, making it a great starting point for thinking “outside the box..." Lipkin and Carpenter have suggested that the forelimbs were used to hold a struggling victim (which had not been dispatched with the first bite) while the final, lethal bite was applied. If that is the case, then the forelimbs must be capable of large angular accelerations α in order to grab the animal attempting to escape. The concepts of the typical first-year physics course are sufficient to test this hypothesis... Naturally, student love solving any problem related to Tyrannosaurus rex.

New GM technique injects mosquitoes with a gene that results in mostly male offspring, eventually leading to a population crash. Previous efforts to tackle the disease, that kills more than 1 million people each year – most of whom are African children – have included bed nets to protect people and insecticides to kill the mosquito species most responsible for the transmission of malaria (Anopheles gambiae). The new technique by a team at Imperial College London involves injecting mosquitoes with a gene that causes the vast majority of their offspring to be male, leading to an eventual dramatic decline in population within six generations as females disappear. “You have a short-term benefit because males don’t bite humans [and transmit malaria],” Andrea Crisanti, one of the authors of the new research, which was published in the journal Nature Communications on Tuesday, told the Guardian. “But in the long term you will eventually eradicate or substantially reduce mosquitoes. This could make a substantial contribution to eradicating malaria, combined with other tools such as insecticides.”
These new mosquitoes are now set to be used in Brazil, having been approved for use by the Brazilian government with a factory for their production now opened.[more inside]

Last November, after five years of remarkable negotiations that unfolded far from the Delta, representatives from the U.S. and Mexico agreed to a complex, multi-part water deal that will give them desperately needed flexibility for weathering the drought. More surprisingly, the two nations will join the team of environmental organizations to release a flood of more than 105,000 acre-feet of water – 3.8 million big-rig tankers' worth – into the Delta's ancient floodplain, and chase it with a smaller, permanent annual flow to sustain the ecosystem.For High Country News, Matt Jenkins describes the most ambitious water sharing plan ever created between Mexico and the United States (single page print version). For much more about this project and the water issues surrounding it, there's Eli Rabett's roundup of John Fleck's blogposts about this. (Or read the tl;dr version by Alex Harrowell.)
It is the unlikeliest of times to pull off a deal like this. Rather than hoarding all the water for themselves in this drought –– the river supplies some 35 million people –– the West's largest water agencies have pledged to send some all the way to the sea. That move is, to some extent, a long-overdue acknowledgment that the U.S. bears responsibility for the impacts its dams have caused beyond its borders. And after years of fruitless court fights in the U.S. by environmental groups, the Mexican government finally insisted that water for the Delta be a cornerstone of the broader deal.
Humans have co-evolved with the resident microbes that call us "home", known as the microbiota, consisting of trillions of cells that colonize our bodies. The microbiota carry out many beneficial functions, such as producing vitamins, aiding in digestion, and protecting against invading microbes, but disruption from antibiotics or delivery by Caesarian section may have consequences for human health. Recently, antibiotic use has been linked with obesity and asthma. Using both human studies and experimentally observed mice, we are beginning to understand how antibiotics may lead to the disappearance of microbes and to identify key microbes that impact our health.[more inside]
