摘要

We investigated the impact of environmental temperature on elevational distributions of a high-mountainous lizard, Takydromus hsuehshanensis, by examining the thermal sensitivity of its locomotor performance. Its sprint speed was measured at 9 body temperatures after 2 wk of acclimation at 2 different temperatures. The same measurements were performed on a closely related species, T. formosanus, which lives at lower elevations. The results indicated that (1) T. hsuehshanensis was capable of maintaining normal locomotor performance within a body temperature range which approximates summer temperatures of lowland areas; (2) T. formosanus was able to run significantly faster than T. hsuehshanensis within a certain range of body temperatures; (3) these 2 species did not differ in their thermal sensitivities of the locomotor performance; and (4) temperature acclimation treatments did not affect the locomotor performance of these 2 species. We concluded that locomotor performance is not a crucial factor limiting the distribution of T. hsuehshanensis in lowland areas.
