Thermal relations of the neotropical frog, Hyla labialis (Anura: Hylidae) /

Abstract

The heliothermic frog, Hyla la- bialis, in Bogota, Colombia, was found to have daily activity patterns primarily con- trolled by temperature; overcast skies re- duced activities. Ambient temperatures af- fected body temperatures, which were main- tained within broad limits. Activity range for body temperatures of H. labialis varied from 11 to 28°C with a mean of 18°C. Body temperatures of most frogs, however, ranged from 13 to 22 °C. Mean body tem- peratures were lowest at night (14.5°C) and highest when basking (22.9°C).
