Abstract
Nocturnal Acomys cahirinus and diurnally active A. russatus coexist in hot rocky deserts. Diurnal and nocturnal activity exposes them to different climatic challenges. A doubly-labelled water field study revealed no significant differences in water turnover between the species at all seasons, reflecting the adaptations of A. russatus to water conservation. In summers the energy expenditure of A. russatus tended to be higher than that of A. cahirinus. Energy requirements of A. cahirinus in winter are double than that of A. russatus, and may reflect the cost of thermoregulating during cold nights.Entities:
