Over time, humans have contributed to the loss of native species and have introduced non-native species throughout Europe. A new analysis shows how European freshwater fish have changed profoundly since 1840. At the continental scale, the contemporary fauna holds net 11 more species today as exoti...

This paper studies the impact of climate change and habitat loss on extinction threshold of species. When global biodiversity is gradually being altered by human activities, species respond differently to such alterations in response to habitat destruction and habitation fragmentation. This alteration of ...
Squids are shrinking, birds are migrating and lizards are getting blown away by hurricanes. The signs are everywhere; animals are changing because of climate change. We asked biologist Thor Hanson to walk us through three animal adaptation experiments.Re
