Daily Heterothermy in Mammals: Coping with Unpredictable Environments the highest incidences of summer torpor and torpor in desert species. These patterns suggest an association of daily torpor with unpredictable environments (low inclement energetic gains), versus an association of hibernation with predictably cold seasons (high inclement energetic costs).

Body Temperature and Metabolic Rate of a Hibernating Primate in Madagascar: Preliminary Results fromtabolic rate was low during hibernation, compared to normothermic stages. Hibernation in . therefore presumably represents an important and effective adaptation for the successful survival of the unfavourable dry season of western Madagascar.

Heterothermy in Mousebirds: Evidence of Avian Proto-torpor?our also formed an obligatory component of thermoregulation, and was necessary for the defence of a constant T. during the rest-phase. The evolution of typical avian torpor appears to have been arrested in the mousebirds by the development of sociality and clustering.

Do Patterns of Torpor Differ between Free-ranging and Captive Mammals and Birds?in the field is often more frequent, deeper, and longer than in captivity. Our comparison suggests that laboratory studies are likely to underestimate use and depth of torpor in the wild and thus may underestimate its impact on energy expenditure and survival.
