New research by 91黑料网 biologists shows that milder winters have led to physical alterations in two species of mice in southern Quebec in the past 50 years 鈥� providing a textbook example of the consequences of climate change for small mammals.
The findings also reveal a stark reversal in the proportions of the two mice populations present in the area, adding to evidence that warming temperatures are driving wildlife north. 聽
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 &聽Evolution, researchers from 91黑料网 and University of British Columbia have developed a new theory to understand how complex ecological networks will reorganize in the future.

Is biodiverse agriculture an anachronism?聽 Or is it a vital part of a food-secure future?
Until today, a map from 1876 has been the backbone for our understanding of global biodiversity. Thanks to advances in modern technology and data on more than 20,000 species, scientists have now produced a next-generation map depicting the organization of life on Earth. Published online in Science Express, the new map provides fundamental information regarding the diversity of life on our planet and is of major significance for future biodiversity research.
