Most studies on how rising temperatures will impact terrestrial ectotherms have focused on
single populations or multiple sympatric species. Addressing the thermal and energetic
implications of climatic variation on multiple allopatric populations of a species will help us
better understand how a species may be impacted by altered climates. We used eight years
of thermal and behavioral data collected from four populations of Pacific rattlesnakes
(Crotalus oreganus) living in climatically distinct habitat types (inland and coastal) to …
