TABLE 1.
Hibernation parameters of the common hamster (Cricetus cricetus), a food-storing species, and the garden dormouse (Eliomys quercinus), a fat-storing species, under controlled conditions of ambient temperature (Ta) and photoperiod.
Hibernation parameters | Food-storing | Fat-storing |
Common hamster | Garden dormouse | |
Hibernation duration (h) | 2385.6 ± 494.4** | 3908.1 ± 32.6 |
Number of torpor bouts* | 26.6 ± 0.6 | 19.4 ± 2.4 |
Mean duration of torpor bouts* (h) | 90.5 ± 2.1 | 195.1 ± 21.4 |
Mean duration of IBE* (h) | 29.4 ± 1.9 | 5.5 ± 1.0 |
Minimal body temperature (°C) | 0.97*** | 6.0 ± 0.8 |
Conditions were for common hamsters (except for minimal body temperature): Ta ∼ 8°C, LD 10/14 h; and for garden dormice: Ta ∼ 5.3°C, LD 0/24 h, i.e., constant darkness. Results are presented as mean values ± SE. Data originated from Mahlert et al. (2018) for the garden dormouse, and from Waßmer and Wollnik (1997) (**) and Wassmer (2004) (***) for the common hamster. *Body temperature threshold for torpor bouts or phases of interbout euthermia (IBE) is of 32°C for common hamsters or 18°C for garden dormice.
