Large endothermic animals generate heat as a byproduct of cellular metabolism with a small contribution from thermogenesis, however, small endothermic animals have a large SA:V and can lose heat at faster rates than larger animals. Thus, smaller endotherms seem to orient their physiology towards heat production rather than generation of ATP. Although studies on dogs show different correlations between internal body temperature (Tb) and body size, the location and method of measurement differs greatly between these studies, and these variables affect temperature readings. As a result of these discrepancies, a comprehensive exploration of a single species and their relationships to body mass and Tb is lacking, and there is a call for determining body size and thermal relations in dogs, especially in light of climate change and the propensity of some breeds to over-heat. We will measure Tb in dogs via ear temperatures and thermal imaging. This project requires knowledge on proper handling of dogs, and also requires some travel.
Must have taken BIOL181 and BIOL182. Preference will be given to students who have a background in physiology and who demonstrate the ability to properly analyze thermal and normal images.
