Abstract

1. We compared resting metabolic rate (RMR) and non-shivering thermogenesis (NST) values between founder and F1-populations of winter-acclimatized Acomys cahirinus that originated from north- and south-facing slopes (NFS and SFS) of the same valley, representing mesic and xeric habitats. 2. NST was measured by the increase in oxygen consumption (VO₂) and body temperature (T_b) after a noradrenaline (NA) injection (VO₂ NA, T_bNA). 3. Body mass and T_bNA values were higher in SFS F1-mice, while RMR and VO₂ NA values were higher in NFS F1-mice. Differences were not apparent in founders. 4. Results are consistent with NFS and SFS mice being considered as "heat producers" and "heat conservers", respectively.
