TL;DR: This review applies classical models of thermal adaptation to predict variation in body temperature within and among populations of mammals and birds and relates these predictions to observations generated by comparative and experimental studies.

TL;DR: Review of published ecological studies using path analysis suggests that path analysis is often misused and collinearity is a moderate to severe problem in a majority of the analyses, suggesting that path coefficients may often mislead ecologists about the relative importance of ecological processes.

TL;DR: Analysis of the causes of latitudinal and thermal clines in the body size of the eastern fence lizard shows that life‐history traits of S. undulatus were more strongly related to latitude than they were to temperature, indicating that both abiotic and biotic factors should be considered as causes of Bergmann's clines.

TL;DR: A reciprocal transplant experiment is used to uncover the relative importance of population-specific (genetic) and environmental sources of variation in individual growth rates between two populations of the fence lizard, Sceloporus undulates, and suggests that the thermal biophysical environment may have reduced growth rates of Nebraska lizards transplanted to New Jersey.

TL;DR: This work tested a specific prediction of this hypothesis by comparing the thermal dependence of sprint speed of nocturnal geckos versus diurnal lizards, and found that optimal temperatures and performance breadths for sprinting of several gecko families do not differ substantially from those of diurnalLizards from other families.
