dc.description.abstract |
Bats are among the most heterothermic mammals, with nearly all species investigated under free-ranging
conditions to date exhibiting some degree of daily torpor and/or hibernation. We investigated thermoregulation
during late winter by seven Nycteris thebaica in a warm, semi-arid habitat in northern South
Africa, using temperature-sensitive transmitters to measure skin temperature (Tskin). Unexpectedly, we
found no evidence for any expression of daily torpor or hibernation based on a total of 86 days of data
from 7 bats (one male and six females), despite air temperatures as low as
∼10 ◦C. Instead, daytime Tskin
was distributed unimodally with most values in the 33–35 ◦C range, and a minimum Tskin of 28.4 ◦C at a
roost temperature of 24.6 ◦C. There are several possible reasons why N. thebaica may avoid torpor, including
predation in roosts, and the long nightly foraging periods of this species compared to many others. |
