Seasonality of torpor patterns and physiological variables of a free-ranging subtropical bat.
Seasonal changes in weather and food availability differ vastly between temperate and subtropical climates, yet knowledge on how free-ranging subtropical insectivorous bats cope with such changes is limited. We quantified ambient temperatures, torpor patterns and thermal physiology of subtropical insectivorous northern long-eared bats, Nyctophilus bifax, during summer (n=13) and winter (n=8) by...

We investigated the importance of energy-conserving strategies for free-ranging Planigale gilesi in arid Australia. We monitored torpor use and basking behaviour using internal temperature-sensitive transmitters. Torpor was used every day; the maximum torpor bout duration was 18.2 h and the minimum body temperature was 10.5 C. Basking behaviour was observed during rewarming from torpor as well ...
متن کاملTorpor in free-ranging tawny frogmouths (Podargus strigoides).
Several small caprimulgiform birds (<80 g) are known to enter torpor, apparently to cope with a fluctuating supply of insect prey. Since the large Australian tawny frogmouth (Podargus strigoides; 381-556 g) is also insectivorous, we investigated its thermoregulatory behaviour and thermal biology to determine whether this species is also heterothermic. In an open woodland at approximately 1,000 ...
