Ancient climate change has left a strong imprint on modern ecosystems

This item was filled under Climate
As Earth’s climate cycles between warm and cool periods, species often must move to stay within suitable conditions. Scientists have now mapped how fast species have had to migrate in the past to keep up with changing climate. They found that small-ranged species – which constitute much of Earth’s biodiversity – are concentrated in regions where little migration has been required. Predicted climate change will drastically increase the required migration rates in many of these locations, putting their unique faunas at risk....
