The ban of the cave bear
At 3.5 meters long and with a shoulder height of 1.7 meters, the cave bear was one of the giants of the Ice Age. Yet few appear to have survived until the last glacial maximum 24,000 to 19,000 years ago. Researchers have conducted analyses to find out what likely caused the extinction of these large herbivores. It is believed that the renewed cooling of the climate and hunting by humans -- added to the bears purely vegetarian diet -- increased the pressure on this megafauna species.

Bats as barometer of climate change
Bats spend every night hard at work for local farmers, consuming over half of their own weight in insects, many of which are harmful agricultural pests, such as the noctuid moths, corn earworm and fall armyworm. And now they are arriving earlier in the season, and some of them are reluctant to leave. It seems the bats know more about climate change than we had realized.

New research reveals plant wonderland inside China's caves
Over five years (2009-2014) researchers have delved into the depths of some of China's most unexplored and unknown caves in the largest ever study on cave floras. Surveying over 60 caves in the Guangxi, Guizhou and Yunnan regions, they were able to assess the vascular plant diversity of cave flora in more detail than ever before.
