Accounting for multiple climate components when estimating climate change exposure and velocity
Christopher P. Nadeau, Angela K. Fuller
2015, Methods in Ecology and Evolution (6) 697-705
The effect of anthropogenic climate change on organisms will likely be related to climate change exposure and velocity at local and regional scales. However, common methods to estimate climate change exposure and velocity ignore important components of climate that are known to affect the ecology and evolution...

Bird species turnover is related to changing predation risk along a vegetation gradient
Joseph A. LaManna, Amy B. Hemenway, Vanna Boccadori, Thomas E. Martin
2015, Ecology (96) 1670-1680
Turnover in animal species along vegetation gradients is often assumed to reflect adaptive habitat preferences that are narrower than the full gradient. Specifically, animals may decline in abundance where their reproductive success is low, and these poor-quality locations differ among species. Yet habitat use does not always appear adaptive. The...
