Niche tracking and rapid establishment of distributional equilibrium in the house sparrow show potential responsiveness of species to climate change. [PDF]

open access: yes, 2012
The ability of species to respond to novel future climates is determined in part by their physiological capacity to tolerate climate change and the degree to which they have reached and continue to maintain distributional equilibrium with the environment.
