Abstract
(1)Metabolic rate (MR), thermal neutral zone (TNZ), body temperature (Tb), and thermal conductance were measured in striped hamsters (Cricetulus barabensis) that were live-trapped in winter and summer.(2)TNZ of winter hamsters was 20.8–30.6 °C and that of summer hamsters was 27.5–32.9 °C. Mean MR within the TNZ was 3.89±0.13 ml O2/g h in winter and 2.58±0.07 ml O2/g h in summer. The seasonal effects on Tb were not significant (P=0.09).(3)The ecological physiology properties for the hamster were higher MR and wider TNZ in winter but a lower MR and narrower TNZ in summer, which were closely related to their living habits, characterized by a cold winter and hot, dry summer.
