A species of mouse deer called the silver-backed chevrotain was thought to be lost to science after 30 years of no sightings, but a video camera in a Vietnam forest captured one as it foraged for food.
From The Guardian:
The pictures of the rabbit-sized animal, also known as the silver-backed chevrotain, are the first to be taken in the wild and come nearly 30 years after the last confirmed sighting.
“We had no idea what to expect, so I was surprised and overjoyed when we checked the camera traps and saw photographs of a chevrotain with silver flanks,” said An Nguyen, a scientist and expedition team leader at Global Wildlife Conservation (GWC).

As a kid in the '70s, watching the annual monarch butterfly migration in Californa was a thing to see! Not so much any more.
From KTLA 5 in LA:

Researchers with an environmental group have labeled as “disturbingly low” the number of western monarch butterflies that migrate along the California coast.
A recent count by the Xerces Society recorded fewer than 30,000 butterflies, which it said is an 86 percent decline since 2017.
By comparison, the group in 1981 counted more than 1 million western monarchs wintering in California, the San Francisco Chronicle reported.
The Xerces Society conducts annual Thanksgiving and New Year’s counts and was not certain what caused the numbers to drop. It said there is no substantial evidence of a delayed migration and butterflies are not being reported in other parts of the country.
A 2017 study by Washington State University researchers found the species likely will go extinct in the next few decades if nothing is done to save it.
Scientists say the butterflies are threatened by pesticides, herbicides and destruction along their migratory route. They also have noted climate change impacts.
A life-size animatronic Tyrannosaurus Rex at a Colorado dinosaur theme park went down in flames yesterday. Zach Reynolds, co-owner of Royal Gorge Dinosaur Experience, says it was probably caused by an electrical malfunction.
Although the 24-foot-tall T-Rex is a big loss to the park, Reynold's had a sense of humor about it when he joked, “We knew he had a temper, but today he blew his top.” He added, "it made for some spectacular imagery along the way."
The good sport hopes a new dinosaur will take its place by this summer.

The last male white Rhino in the world has died at 45 years of age.
The rhino, named Sudan, had been suffering from age-related ill-health for some time, according to AFP.
During the 1970s and 1980s the white rhino was damn near wiped out in Africa, thanks to the high demand of its horn for use in dagger handles in parts of Yemen and as a medicinal ingredient in China. Sudan's death all but cinches the death of the white rhino sub-species. Early in the new millennium, the species was nearly obliterated in the wild, as the few remaining white rhinos, numbering perhaps 20 to 30, were killed in the crossfire of the First Congo War, among other conflicts, in the Democratic Republic of Congo and Rwanda.
With Sudan's passing, you'd think that the fate of the white rhino would be cinched. And you'd be right--theoretically.
While there are no more male specimens of the species, thanks to us, a few females remain. It's hoped that it may still be possible to use Sudan's genetic material to keep the species going:

"Sudan was the last northern white rhino that was born in the wild. His death is a cruel symbol of human disregard for nature and it saddened everyone who knew him," said Jan Stejskal, Director of International Projects at the Dvur Kralove Zoo.
"But we should not give up. We must take advantage of the unique situation in which cellular technologies are utilized for conservation of critically endangered species.

This is the Yangtze giant softshell turtle, one of the most endangered species on Earth. There are two at China's Suzhou Zoo and one in the wild in Vietnam's lake Dong Mo. Conservationists really need to find a fourth to aid their efforts to rebuild the species. National Geographic spoke with Aimin Wang, director of the China division of the Wildlife Conservation Society, about the group's efforts to find another elusive Yangtze turtle:

What would it mean for the species if one were to be found?
It increases our opportunity [for successful breeding] quite a bit. The male in China is quite old, but the female is young. The turtles are bred using artificial insemination. The last four attempts with the breeding pair in China were unsuccessful. We just tried for a fifth time and got high-quality sperm. We won't know for another month if our results were successful.
Why are these turtles so important to save?
This is a flagship species, and for biodiversity, they're quite important. They serve as an important [indicator of environmental health]. If we can help them survive, that means our ecological system is quite good. If they disappear, that means our ecological system is quite bad.
Pangolin scales, like rhinoceros horns, are just made of keratin, but that doesn't stop traditional medicine practitioners from claiming they cure cancer and what-not. It's why pangolins are the most trafficked animals in the world. China stopped a shipment worth around $2 million that required killing around 7,500 of the cure little anteaters. Read the rest
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.

Species that lack significant levels of genetic diversity have a big problem. And it's not just about ending up with tiger and kiwi bird versions of Cletus the Slack-Jawed Yokel. Beyond the risk of inbreeding, genetic diversity supplies the tools that help a species adapt to change. If there's not enough of it, then the species is more likely to die out when subjected to stressful conditions ... like, say, climate change. Read the rest
By this point in your lives, most of you are by no doubt aware of the massive slaughter of buffalo that happened in the United States in the late 19th century. Across the plains, thousands of buffalo were killed every week during a brief period where the hides of these animals could fetch upwards of $10 a pop. (The Bureau of Labor Statistics inflation calculator only goes back to 1913, so it's hard for me to say what that's worth today. But we know from the context that even when the value of buffalo hides dropped to $1 each, the business of killing and skinning buffalo was still considered a damned fine living.)
You might think that the business ended there, with dead, skinned buffalo left to rot on the prairie. And you're sort of right. But, in a story at Bloomberg News, Tim Heffernan explains that, a few years later, those dead buffalo created another boom and bust industry—the bone collection business.

Animal bones were useful things in the 19th century. Dried and charred, they produced a substance called bone black. When coarsely crushed, it could filter impurities out of sugar-cane juice, leaving a clear liquid that evaporated to produce pure white sugar -- a lucrative industry. Bone black also made a useful pigment for paints, dyes and cosmetics, and acted as a dry lubricant for iron and steel forgings.
... And so the homesteaders gathered the buffalo bones. It was easy work: Children could do it. Carted to town, a ton of bones fetched a few dollars.
It's October 25, 2011, and another subspecies of the Javan rhinoceros has gone extinct. There's only one subspecies left, and it's down to 50 individuals. Read the rest
