Variation in Temperature Preference with Stage of Development of Bufo marinus Larvae

Abstract

The temperature preference of Bufo marinus larvae was determined at six stages of development. At stage 37 the temperature preference of the larvae was also determined at each of three acclimation temperatures. Preferred temperature generally increased as larval development progressed. This trend was compared with the thermal tolerance at different stages of development. There was no significant correlation between temperature tolerance and temperature preference. The temperatures experienced by tadpoles in nature as they select different microhabitats at different stages of development showed a trend similar to the temperature preferences. Different acclimation temperatures at stage 37 had no effect on temperature preference.
