Thermal Tolerance of Fruit-Feeding Butterflies (Lepidoptera: Nymphalidae) in Contrasting Mountaintop Environments.

Ectothermic organisms, such as insects, are highly temperature dependent and are good models for studies that predict organisms' responses to global climate change. Predicting how climate change may affect species distributions is a complicated task. However, it is possible to estimate species' physiological constraints through maximum critical temperature, which may indicate if the species can tolerate new climates.
