Résumé
Some aspects of torpor have been studied among captive Suncus etruscus by recording the nest temperature. Torpors show a circadian pattern and occur spontaneously or can be induced by food shortage. Body temperature can be controlled during torpor, remaining relatively high at low ambiant temperatures. At 20° C, spontaneous torpors seem to be less deep than induced tropors, but both show similar patterns at 5-8 ° C. Spontaneous torpors begin between 01°° and 06°°, whereas the onset of diet induced torpors seems to depend also on food exhausting. The rates of activity (A) and of torpor (T) show under constant conditions a daily variability. Increase of T is linked with a decrease of A and the relationship could agree with A(%) = Ao( 1-T/100), where Ao is daily rate of activity when T = 0. Occurence of torpor among other Soricidae, possible occurence among free living Suncus etruscus and energy saving are discussed
