Evolution, ecosystems may buffer some species against climate change

[Source: ScienceDaily] - Although ecologists expect many species will be harmed by climate change, some species could be buffered by their potential to evolve or by changes in their surrounding ecosystems.

Researchers at the University of Wisconsin-Madison and the University of Arizona are using a common agricultural insect pest to understand how ecological and evolutionary factors drive population shifts in the face of a changing environment.

A study appearing March 6 in the journal Science shows that both ecological interactions within a food web and the potential for rapid evolutionary adaptation play critical roles in determining how populations of the legume-loving pea aphid fare during increasing bouts of hot weather, one aspect of predicted climate change.
