Behavior of the terrestrial nocturnal lizards Goniurosaurus kuroiwae kuroiwae and Eublepharis macularius (Reptilia: Eublepharidae) in a thigmothermal gradient

1.Two eublepharid gecko species were tested for their thermal preferences in a thigmothermal gradient.2.Goniurosaurus kuroiwae kuroiwae from a humid subtropical Oriental forest selected a lower body temperature (Tp; average 16.6 °C) than Eublepharis macularius from an arid Palaearctic area (25.8 °C).3.Both the locations of animals along the gradient and the Tp were significantly more variable among G. k. kuroiwae than among E. macularius.4.There were no significant differences in Tp and in its variance between photophase and scotophase in either species.
