Studies Shed Light On Why Species Stay or Go in Response to Climate Change

ScienceDaily (Aug. 17, 2012) — Two new studies by scientists at UC Berkeley provide a clearer picture of why some species move in response to climate change, and where they go.

“One study, published online Aug. 6, in the journal Global Change Biology, finds that changes in precipitation have been underappreciated as a factor in driving bird species out of their normal range.

…study's findings challenge the conventional reliance on temperature as the only climate-related force impacting where species live.

‘Temperature did not explain the majority of these shifts,' said Tingley... 'Only when we included precipitation as an explanatory variable did our models adequately explain the movement patterns we observed.’”
