Many species might be left vulnerable in the face of climate change, unable to adapt their physiologies to respond to rapid global warming. According to a team of international researchers, species evolve heat tolerance more slowly than cold tolerance, and the level of heat they can adapt to has limits.

One of the world’s 7,000 languages vanishes every other week, and half – including scores of indigenous North American languages -- might not survive the 21st century, experts say. To preserve as much linguistic diversity as possible in the face of this threat, 9IÖÆ×÷³§Ãâ·Ñ scientists are proposing to borrow a leaf from conservation biology.

Ecosystems are a complex web of interactions. These ecological networks are being reorganized by extinctions and colonization events caused by human impacts, such as climate change and habitat destruction. In a paper published this week in Nature Ecology & Evolution, researchers from 9IÖÆ×÷³§Ãâ·Ñ and University of British Columbia have developed a new theory to understand how complex ecological networks will reorganize in the future.
