Integrating Thermal Physiology and Ecology of Ectotherms: A Discussion of Approaches

DOI: http://dx.doi.org/10.1093/icb/19.1.357 357-366 First published online: 1 February 1979


An understanding of interactions between the thermal physiology and ecology of ectotherms remains elusive, partly because information on the relative performance of whole-animal physiological systems at ecologically relevant body temperatures is limited. After discussing physiological systems that have direct links to ecology (e.g., growth, locomotor ability), we review analytical methods of describing and comparing certain aspects of performance (including optimal temperature range, thermal performance breadth), apply these techniques in an example on the thermal sensitivity of locomotion in frogs, and evaluate potential applications.
