In the midst of yet another shitty news cycle, it's nice to hear that great things can still happen.

Earlier this year, the state of Wyoming said "yeah" to allowing a maximum of 22 grizzly bears, once sheltered as a protected species, to be hunted. Yesterday, U.S. District Court Judge Dana Christensen said "nah" to hunters gearing up to shoot at grizzly bears that call the Greater Yellowstone Ecosystem home.

From Earther:

In his order, Christensen made clear that the case “is not about the ethics of hunting, and it is not about solving human- or livestock-grizzly conflicts as a practical philosophical manner.”

Instead, the case was about whether the decision to de-list this segment of the Lower 48 grizzly population was scientifically sound. (Grizzly bears as a whole still enjoy endangered species protections across the Lower 48.) Christensen felt that it wasn’t, writing that FWS “failed to consider how reduced protections in the Greater Yellowstone Ecosystem would impact the other grizzly populations.”

The ruling drew heavily on a case the federal agency lost last year, when its decision to de-list Western Great Lakes region gray wolves was vacated in court for failing to consider species-wide impacts.

In the United States, there's only around 1,800 grizzly bears roaming Montana, Wyoming, Washington, Idaho and Montana. That's far from what I or any ecologist (of which I am not) would call a recovered species. Earther points out that while the Yellowstone grizzly population has rebounded in recent years, it's still isolated from other populations. Read the rest

The little pink-edged ferns above are Azolla filiculoides, and they're smaller than a fingernail. Scientists just made it the first fern to get its genome sequenced because of its potential for fertilizing and even cooling the planet. Fifty million years ago, it was so abundant as ocean blooms that it helped cool the earth's atmosphere. Via Quartz:

This great Azolla boom was so successful that it lasted for 800,000 years, and is now known to paleobotanists as the “Azolla event.” Green plants suck up carbon dioxide; Azolla is particularly good at doing so. Over that period, researchers believe it sequestered about 10 trillion tons of carbon dioxide from the Earth’s atmosphere, or well over 200 times the total amount of carbon dioxide humans currently release into the atmosphere every year.

During the Azolla boom, global temperatures plummeted, suggesting the diminutive fern “played a key role in transitioning Earth from a hot house to the cool place it is today,” Fay-Wei Li, a plant evolutionary biologist at Cornell University, said in a press release. As Yale’s E360 pointed out, scientists have wondered for years if Azolla could be harnessed to cool the planet again.

As Earth's human population expands, it's harder for other mammals to avoid people during the daytime. As a result, some mammals are becoming increasingly nocturnal. Nobody knows how that shift will affect individual species and even entire ecosystems. In a new paper in the journal Science, University of California, Berkeley wildlife ecologist Kaitlyn Gaynor and her colleagues examined data on how 62 species across the world spend their days and night. From Scientific American:

For example, leopards in the Central African nation of Gabon are 46 percent nocturnal in areas without bushmeat hunting, but 93 percent nocturnal where the practice is common. In Poland wild boars go from 48 percent nocturnal in natural forests to 90 percent nocturnal in urban areas. Even activities people consider relatively innocuous, such as hiking and wildlife viewing, strongly affected animals’ daily rhythms. Brown bears in Alaska live 33 percent of the day nocturnally when humans stay away, but that number goes up to 76 percent for bears exposed to wildlife-viewing tourism. “We think that we're leaving no trace often when we’re outdoors, but we can be having lasting consequences on animal behavior,” Gaynor says...

Perhaps even more alarming is the cascade of effects that could occur in the wider ecosystem as animals switch from day to night. “Patterns of competition and predator–prey interactions might change with the nocturnal behavioral changes,” Gaynor says. If one species—say a top predator—starts hunting at night and goes after different types of prey, it will likely have innumerable trickle-down consequences for everything along the food chain.

What follows is the most mind-altering first chapter I've read in a long time, from biomechanist Katy Bowman’s latest book Movement Matters: Essays on movement science, movement ecology, and the nature of movement. 

These items —an electronic car unlocker and a tea bag— are convenient. But what I’ve realized is, when we say or think “convenience,” it’s not as much about saving time as it is about reducing movement. We can grasp sedentary behaviour as it related to exercise because it’s easy to see the difference between exercising one hour a day and not exercising one hour a day. My work, in the past, has been about challenging people to also be able to see the difference between exercising one hour a day and not exercising the other twenty-three. More subtle still—and what I’m asking you to do now—is to see how the choice to move is presented to you every moment of the day, but how most often we select the most sedentary choice without even realizing it. 

Our daily life is composed of a lot of seemingly innocuous ways we’ve outsourced our body’s work. One of the reasons I’ve begun focusing just as much on non-exercisey movements as I do on exercise-type movements is that I feel that the ten thousand outsourcing a day during the 23/24ths of your time hold the most potential for radical change. Be on the lookout for these things. To avoid the movements necessary to walk around to all the car doors, or just to avoid turning your wrist, or to avoid gathering your tea strainer and dumping the leaves and cleaning the strainer (in your dishwasher?), you have accepted a handful of garbage, plastic (future landfill), and a battery.

In 1997, ecologists Daniel Janzen and Winnie Hallwachs convinced a Costa Rican orange juice maker to to dump their waste peels in a clear-cut abandoned pasture that was in a national park. Twenty years later, the enriched soil nourishes tropical forest again, according to a new report. Read the rest

This mysteriously "tattooed" fish was caught near Lopez Jaena in the Misamis Occidental province of the Philippines. Some locals considered the fish a warning from the depths. They're actually right, as the likely non-magical explanation is that the fish was caught in a printed plastic bag floating in the ocean and the pattern transferred to the animal's scales over time. (Mysterious Universe)

UPDATE:

According to ABS-CBN, "Zosimo Tano who caught the fish, clarified... that the print on the fish's body came from his shirt, which he used to cover the fish."

Between April and July, Iran's salty Lake Urmia changed from a bright green color to a blood red. NASA's Aqua satellite captured the image above and reported on the science behind the strange transformation. According to NASA, the periodic color change is caused by micro algae producing carotenoids that help with photosynthesis and act as antioxidants and Halobacteriaceae, a bacteria in very salty water that releases "a red pigment called bacteriorhodopsin that absorbs light and converts it into energy for the bacteria." From NASA:

The color changes have become common in the spring and early summer due to seasonal precipitation and climate patterns. Spring is the wettest season in northwestern Iran, with rainfall usually peaking in April. Snow on nearby mountains within the watershed also melts in the spring. The combination of rain and snowmelt sends a surge of fresh water into Lake Urmia in April and May. By July, the influx of fresh water has tapered off and lake levels begin to drop.

The fresh water in the spring drives salinity levels down, but the lake generally becomes saltier as summer heat and dryness take hold. That’s when the microorganisms show their colors, too. Careful sampling of the water would be required to determine which organisms transformed the lake in 2016, but scientists say there are likely two main groups of organisms involved: a family of algae called Dunaliella and an archaic family of bacteria known as Halobacteriaceae.

While Lake Urmia has shifted from green to red and back several times in recent years, trends suggest that a red Urmia could become increasingly common.

The Monarch butterfly is headed to rapid extinction in the eastern US, reports Scott K. Johnson, because its complex ecosystem continues to collapse.

…humans are responsible. The life cycle of the monarch is tightly linked with the milkweed plant. Females lay almost all of their eggs on these plants, and the larvae happily munch on them when they hatch. Milkweed tends to pop up in areas where the soil has been disturbed, like farm fields.

As with other weeds, farmers have long tried to keep milkweed from growing amidst (and competing with) their crops. But the introduction of genetically modified corn and soybeans that could survive being sprayed by the herbicide glyphosate (better known by its original trade name “Roundup”) suddenly gave farmers a more effective way to clear plants like milkweed.

These are the "walking palm trees" of Ecuador. Each year, they could walk as much as 20 meters. Slower than the Ents from Lord of the Rings but, well, real.

“As the soil erodes, the tree grows new, long roots that find new and more solid ground, sometimes up to 20m,” Peter Vrsansky, a palaeobiologist from the Earth Science Institute of the Slovak Academy of Sciences Bratislava, tells the BBC. “Then, slowly, as the roots settle in the new soil and the tree bends patiently toward the new roots, the old roots slowly lift into the air. The whole process for the tree to relocate to a new place with better sunlight and more solid ground can take a couple of years.”

Tragically, the incredible Sumaco Biosphere Reserve where they live is being chopped down.

“This [cutting] is a shame, as Ecuador is one of the world countries with the highest partition of protected areas," Vransky says, But the trees can’t walk fast enough to escape the chainsaw and the machetes backed by current legislation." Read the rest
