Temperate reptile populations are under strong selective pressure to minimize the costs of extreme winter temperatures. For high latitude and high elevation snake populations, this has often favored communal overwintering behavior, wherein large numbers of conspecifics aggregate at optimal sites given the limited availability of such features in the environment. Timber Rattlesnakes (Crotalus horridus) are distributed across a wide latitudinal gradient in North America, and therefore represent ideal models for exploring how variable winter selective regimes might favor different strategies. Here, we leverage a unique intermediate population of C. horridus from central Georgia, USA, that exhibits both communal …
