Abstract:We studied thermal tolerance, body temperature, and thermal dependence of locomotor performance of hatchling red eared slider turtles ( Trachemys scripta elegans ). Two thermal environments, one with and the other without thermal gradients, were designed to study diel variation in body temperature (Tb) . Turtles were obtained from a pet shop in Hangzhou, with body mass, carapace length and carapace width being 9 5 ± 0 2 (7 7~11 1) g, 35 6 ± 0 2 (32 7~37 4) mm and 35 3 ± 0 2 (33 6~36 9) mm,...
