TL;DR: Focal species analyses show that some tropical forest lizards were already experiencing stressful body temperatures in summer when studied several decades ago, and simulations suggest that warming will not only further depress their physiological performance in summer, but will also enable warm-adapted, open-habitat competitors and predators to invade forests.

TL;DR: A sample analysis of the thermal biology of three Anolis lizards in Puerto Rico demonstrates the utility of the new protocol and its superiority to previous methods of evaluating temperature regulation.

TL;DR: A null model is developed that quantifies the impact of regulatory behaviors on body temperature and on performance of ectotherms and supports the alternative view that behavior has diverse—and sometimes conflicting—effects on the directions and rates at which other traits evolve.

TL;DR: Hypothetical performance curves of ectotherms as function of body temperature suggest that the categories "specialist" and "generalist" are not discrete but are endpoints on a continuum.

TL;DR: It is found that evolutionary divergence overcomes niche conservatism: closely relatedspecies are no more ecologically similar than expected by random divergence and some distantly related species are Ecologically similar, leading to a community in which the relationship between ecological similarity and phylogenetic relatedness is very weak.
