| Abstract: | - (1)We designed a physical model that simulates the thermal and evaporative properties of live Western toads (Bufo boreas).
- (2)In controlled tests, the model tracked the body temperature of live toads with an average error of 0.3±0.03 °C (test range=4–30 °C).
- (3)It estimated the evaporative water loss of live toads with an average error of 0.35–0.65 g/h, or about 14% (test range=0.7–9 g/h).
- (4)Data collected with this physical model should provide an effective way for biologists to better understand habitat selection in toads and other amphibians
