Do pandas eat meat? New footage from China shows a person munching on flesh. Among other things, pandas are famous for their diet. The giant, round panda, native to south-central China, is a folivore, although belonging to the order of carnivores. Bamboo shoots and leaves make up 99% of their vegetarian diet. Since they typically spend 10 to 16 hours a day foraging, they need at least two different species of bamboo to satisfy their hunger. However, their digestive system is typical of a carnivore and the rest of the 1% of their diet includes eggs, forage in farmland for kidney beans, pumpkin, etc. But can they eat meat? According to recent images from a nature reserve in Shaanxi province (northwest China), probably yes. A giant panda was filmed holding and nibbling at the bones of a dead animal. The video was shared by CCTV Video News Agency.

The recording, shared on YouTube by CCTV Video News Agency, was captured as part of a field survey of the population. Researchers were studying the habitats of pandas in Foping National Nature Reserve in Hanzhong City. Ranger Li Shuiping counted the number of pandas with his team. As no bamboo forest was spotted on this great mountain slope, they became curious about what the giant panda was chewing.

They saw several eaten bones, probably from an animal carcass, scattered around the adult panda. After awhile, the panda was seen dropping the bone, turning around, and heading back into the woods.

The researchers took fecal samples from the panda and studied them. They found that the feces were different from the usual bamboo diet and that there were about twenty pieces of animal bone residue.

According to Li, this was the second time they had seen a giant panda gnawing meat in the Qinling Mountains. The last time they recorded a similar video, it was also in winter.

Li Sheng, a researcher at Peking University and an expert at the International Union for Conservation of Nature, mentioned that earlier recordings showed wild giant pandas eating meat in other nature reserves in different provinces of China. . Since their ancestors were omnivorous and giant pandas were forced to change their bamboo diet to adapt to climate change and habitat, they still retain the digestive tract of a carnivore.

Research records show that giant pandas sometimes treat themselves to something special, mostly from animal remains. However, what the behavior or what the complementary animal food source means for wild giant pandas is yet to be further investigated.

The Foping Reserve, part of UNESCO’s Man and the Biosphere Program, has the highest density of panda populations in the country.

]]> How La Niña and climate change can enable our current parade of atmospheric rivers. Tue, 30 Nov 2021 03:18:11 +0000

La Niña plays a role in allowing our current parade of atmospheric rivers across the Pacific and there could be a link to climate change as well.

Faron Anslow, head of climate analysis and monitoring at the Pacific Climate Impacts Consortium, explains, “The global source of almost all atmospheric rivers here and around the world are the tropics.”

“The water evaporates from the warm ocean there and rises due to the thunderstorm activity and eventually this water vapor moves north and gets carried away in the storm tracks which then bring the water in British Columbia “

“With this next storm coming, it looks like this water has come from close to the Philippines and that has been a feature that has been with us for a good part of the year.

The next atmospheric river will impact the south coast of British Columbia on Tuesday and Wednesday.

“For reasons we’re not entirely clear on yet, water vapor has been dragged into storms repeatedly for months now.”

Located off the coast of the Philippines is an area of ​​the Pacific Ocean called the Indo-Pacific Hot Water Pool. A scientific article calls this region the “steam engine” of the world. “

“This is a region of the planet with the warmest ocean temperatures in the world and because of that it is able to withstand what we call really deep convection where there are thunderstorms that go from the surface to the top. to the stratosphere, ”Anslow said.

According to a peer-reviewed scientific article in Science Advances, this Indo-Pacific warm water basin has grown and warmed over the past century due to climate change.

“Research shows that the warmest ocean temperatures in this region are increasing. So basically, as entire regions heat up, the areas that reach that critical threshold for convection get wider and wider to the north and south, ”Anslow said.

“My guess is that the expansion makes it a bit easier for these storms to pick up that moisture and push it across the Pacific Ocean to us.”

In addition, La Niña, which is happening now, is also increasing the moisture export from the Indo-Pacific warm water basin.

“The La Niña model is for warmer than normal ocean temperatures in this warm pool area,” Anslow said.

“So the Niña in this case enhances that hot pool effect and allows all that moisture to be exported. “

Clearly shown in this upcoming atmospheric river.

“This current storm has a very clear wet trail that stretches from British Columbia all the way to quite close to the Philippines, so all the way across the Pacific Ocean for over 10,000 km.”

Strange ‘eggshell’ exoplanets could have ultra-smooth surfaces Mon, 29 Nov 2021 11:30:52 +0000

Weird, newly theorized “eggshell planets” may possess ultra-thin outer layers with ultra-smooth surfaces unlike those seen in any world to date, a new study reports.

Astronomers may have already detected at least three eggshell planets, the scientists noted.
