Energetic advantages of slight drops in body temperature in little brown bats, Myotis lucifugus

(Uploaded by Plazi for the Bat Literature Project) 1. 1. At constant ambient temperatures (Ta) below their thermal neutral zone (TNZ), little brown bats, Myotis lucifugus, maintain a wide range of steady-state body temperatures (Tb). 2. 2. The relationship between oxygen consumption and Tb-Tb differential at constant Tbs below the TNZ is curvilinear. 3. 3. Small drops in Tb from high Tb levels result in significantly greater energy savings than subsequent Tb reductions of equal increments. © 1981.
