... and A. tigrinum , or with skin alone, Desmognathus ochrophaeus and D. quadramaculatus , attained a steady-state , during exercise in a treadmill respirometer. Endurance was correlated with the speed at which maximal was attained Low aerobic costs of transport (60-80% lower than reptiles of similar mass) increased...

... rates of evaporative heat loss. The effect of airspeed on endurance was measured systematically on one bat. Endurance was not limited by energy reserves at all airspeeds, and flight times were significantly greater at the airspeed of minimum power input (V mp). The endurance of both bats was so reduced...
