Effects of body temperature on initial bite force in three species of rock- and crevice-dwelling lizards from Mexico

Bite force can be an important aspect of a lizard’s organismal performance, and is likely to subject influence by ambient conditions including individual’s thermal environment. We examined the effects body temperature (T b ) on initial bite rock- crevice-dwelling individuals three species lizards: Abronia graminea (Anguidae), Barisia imbricata Xenosaurus fractus (Xenosauridae) from Mexico. In B. X. one site (Xochititan, Puebla) was greatest at intermediate T . contrast, second (Tlatlauquitepec, showed weak tendency for increase with Initial in A. not affected Taking our results together, we infer that or lizards often, but always, related
