Hibernation is associated with increased survival and the evolution of slow life histories among mammals
TLDR
The combined results suggest that hibernation is associated with high rates of overwinter and annual survival, and an increase in survival in hibernating species is linked with the coevolution of traits indicative of relatively slow life histories.
Winter activity of Australian tree-roosting bats: influence of temperature and climatic patterns
TLDR
Winter activity of tree-roosting bats is linked to short-term mild conditions caused by a specific, reoccurring weather pattern and climatic shifts that reduce the frequency of such weather events, such as the El Nino Southern Oscillation phenomenon and future human-induced climate change, may also reduce winter activity and/or increase the cost of necessary arousal periods by hibernating tree- roostingbats.
Measuring telomere length and telomere dynamics in evolutionary biology and ecology
TLDR
An overview of the advantages and drawbacks of each method to measure telomere length is provided, with a particular focus on issues that are likely to face ecologists and evolutionary biologists collecting samples in the field or in organisms that may never have been studied in this context before.
THERMOREGULATORY BEHAVIOR OF TREE-ROOSTING CHOCOLATE WATTLED BATS (CHALINOLOBUS MORIO) DURING SUMMER AND WINTER

  • 21 April 2006
TLDR
Temperature telemetry data shows that male C. morio frequently enter torpor in summer and provides the 1st direct evidence of winter hibernation by tree-roosting bats.
Roosting and thermoregulatory behaviour of male Gould’s long-eared bats, Nyctophilus gouldi: energetic benefits of thermally unstable tree roosts
TLDR
Temperature telemetry was used to locate roosts and record the thermoregulatory behaviour of male long-eared bats, Nyctophilus gouldi, during late spring in the Northern Tablelands of New South Wales to gain an energetic advantage from choosing poorly insulated and often sun-exposed roosted bats.
Hibernation and daily torpor minimize mammalian extinctions
TLDR
Evidence is provided that almost all (93.5%) of 61 recently extinct mammal species were homeothermic, maintaining a constant high body temperature and thus energy expenditure, which demands a high intake of food, long foraging times, and thus exposure to predators.
Torpor and thermal energetics in a tiny Australian vespertilionid, the little forest bat (Vespadelus vulturnus)
TLDR
The hypothesis that vespertilionid bats have evolved energy-conserving physiological traits, such as low BMR and proclivity for torpor, is supported.
Hibernation by tree-roosting bats
TLDR
This study provides further evidence that models of torpor patterns and energy expenditure from hibernators in cold temperate climates are not directly applicable in milder climates, where prolonged torpor can be interspersed with more frequent arousals and occasional foraging.
Thermal physiology of pregnant and lactating female and male long-eared bats, Nyctophilus geoffroyi and N. gouldi
TLDR
Under identical thermal conditions, thermal physiology of pregnant and lactating female and male bats are indistinguishable, which suggests that the observed reluctance by reproductive females to enter torpor in the field is predominantly because of ecological rather than physiological differences, which reflect the fact that females roost gregariously whereas male bats typically roost solitarily.
Regulation of heart rate and rumen temperature in red deer: effects of season and food intake
TLDR
The hypothesis that a reduction in body temperature is a physiological mechanism employed even by large mammals, like red deer, to reduce their energy expenditure during periods of negative energy balance is supported.
