SAN FRANCISCO (March 16, 2021) - Over the course of Earth s history, several mass extinction events have destroyed ecosystems, including one that famously wiped out the dinosaurs. But none were as devastating as The Great Dying, which took place 252 million years ago during the end of the Permian period. A new study, published today in
Proceedings of the Royal Society B, shows in detail how life recovered in comparison to two smaller extinction events. The international study team composed of researchers from the China University of Geosciences, the California Academy of Sciences, the University of Bristol, Missouri University of Science and Technology, and the Chinese Academy of Sciences showed for the first time that the end-Permian mass ....

Not just CO2: Rising temperatures also alter photosynthesis in a changing climate

CHAMPAIGN, Ill. Agricultural scientists who study climate change often focus on how increasing atmospheric carbon dioxide levels will affect crop yields. But rising temperatures are likely to complicate the picture, researchers report in a new review of the topic.
Published in the
Journal of Experimental Botany, the review explores how higher temperatures influence plant growth and viability despite the greater availability of atmospheric CO2, a key component of photosynthesis. ....

Researchers discover intact plant fossils beneath Greenland's ice sheet for the first time

For the first time ever, researchers have found fossils under Greenland s ice sheet that are so large and well preserved that they can be seen with the naked eye. The fossils reveal several million years of details about climate and plant life in Greenland according to the UCPH researcher behind the discovery. ....

Study shows how varying climate conditions impact vulnerable species

New findings on the diet of Arctic foxes, determined by the condition of their teeth, show how varying climate conditions in the Arctic affect the animals that live there.
In a study published in
Polar Biology, Peter Ungar, Distinguished Professor of anthropology at the University of Arkansas, and several co-authors analyzed tooth breakage and wear - both gross and micro - of Arctic foxes from Russia s Yamal Peninsula.
Studying the effect of varying climate conditions within this region helps scientists understand the impact of climate change on vulnerable animals and could explain future responses and adaptation, given the warming trend and thawing in Arctic areas. The researchers study is the first to combine dental proxies for short-term, or seasonal, and long-term, or lifetime, diet to better understand how resource depletion affects species differently in different locations within the Arctic. ....

University of Utah scientists plumb the depths of the world's tallest geyser

When Steamboat Geyser, the world s tallest, started erupting again in 2018 in Yellowstone National Park after decades of relative silence, it raised a few tantalizing scientific questions. Why is it so tall? Why is it erupting again now? And what can we learn about it before it goes quiet again?
The University of Utah has been studying the geology and seismology of Yellowstone and its unique features for decades, so U scientists were ready to jump at the opportunity to get an unprecedented look at the workings of Steamboat Geyser. Their findings provide a picture of the depth of the geyser as well as a redefinition of a long-assumed relationship between the geyser and a nearb ....
