Projecting dispersal corridors for climate-change-driven range shifts

Cities, farms reroute animals seeking cooler climes

In spite of considerable human development, the southeastern United States region could provide some of the Western Hemisphere's more heavily used thoroughfares for mammals, birds and amphibians on their way to cooler environments in a warming world, according to new research published in the journal Ecology Letters (link to paper).

The region is among half a dozen areas that could experience heavier traffic compared with the average species-movement across the Western Hemisphere in response to a warming climate. The estimate in southeastern states, for example, is up to 2.5 times the average amount of movement across North and South America.

Other areas that could see pronounced animal movements are northeastern North America, including around the Great Lakes and north into Canada; southeastern Brazil, home to both the species-rich Atlantic Forest and major cities such as Sao Paulo with its ...
