Morphological, sprint performance, survival, and thermal ecological data for tree lizards used in this study.

Raw measurements of morphology (body size, hind limb length, and mass), estimates of maximal sprint speed (on two substrates), thermal data (body temperature and preferred temperatures in a laboratory gradient), and field survival data (absolute and relative fitness) on the adult tree lizards (Urosaurus ornatus) included in our study. Data are divided into three tabs-one tab for each sex (male/female) for the main dataset, and a third tab that includes thermal preference data for the supplementary materials (Text S1). Tabs also include columns indicating the habitat type (boulder/tree) and population (two per habitat) surveyed, and individual lizard identifiers, that we used. The final tab (labeled 'Variable KEY') provides further description of the data (with variable units, when applicable).
