Temperature Dependent Assimilation Efficiencies of Two Species of Terrestrial Salamanders
Bobka MS, Jaeger RG, Mcnaught DC. 1981. Temperature Dependent Assimilation Efficiencies of Two Species of Terrestrial Salamanders. Copeia. 1981(2):417-421
Assimilation efficiencies of Plethodon cinereus and P. shenandoah were measured at 10-20 C using C14 labelled Drosophila melanogaster. Assimilation efficiency was inversely related to ambient temperature for both species, but there were no significant differences between the assimilation efficiencies of the two species at two temperatures. Since the metabolic rate of P. cinereus is directly related to temperature, these salamanders may have difficulty maintaining a positive energy budget during warm periods in forest habitats.
