Introduction to the Special Issue-Beyond CTMAX and CTMIN : Advances in Studying the Thermal Limits of Reptiles and Amphibians.

Two themes emerging from the special issue "Beyond CTMAX and CTMIN : Advances in Studying the Thermal Limits of Reptiles and Amphibians" are: (1) the need to identify mechanisms that determine the shape of thermal performance curves and (2) how these curves can be best used predictively.
