Title: | Roosting and thermoregulatory behaviour of male Gould's long-eared bats, 'Nyctophilus gouldi': energetic benefits of thermally unstable tree roosts | Contributor(s): | Turbill, Christopher (author) | Publication Date: | 2006 | DOI: | 10.1071/ZO05068 | Handle Link: | https://hdl.handle.net/1959.11/2784 | Abstract: | Information about the thermal biology of bats in relation to their roosting behaviour is scant. I used temperature telemetry to locate roosts and record the thermoregulatory behaviour of male long-eared bats, 'Nyctophilus gouldi' (9 g), during late spring in the Northern Tablelands of New South Wales. Bats roosted under bark and in tree cavities, where they typically experienced wide daily fluctuations in ambient temperature (Ta). On 13 out of 16 days, bats employed two torpor bouts per day, during the early morning and late afternoon, coinciding with times of low Ta. Heating of roosts during the day resulted in up to 20°C of passive re-warming before active arousal and provided high Ta around midday when bats were normothermic. By switching between torpor and nonthermic thermoregulation according to the daily Ta cycle, male 'N. gouldi' appear to gain an energetic advantage from choosing poorly insulated and often sun-exposed roosts. | Publication Type: | Journal Article | Source of Publication: | Australian Journal of Zoology, 54(1), p. 57-60 | Publisher: | CSIRO Publishing | Place of Publication: | Australia | ISSN: | 1446-5698 0004-959X |
