Male bats respond to adverse conditions with larger colonies and increased torpor use during sperm production
Sign Up to like & getrecommendations! Published in 2020 at "Mammalian Biology"
DOI: 10.1007/s42991-020-00071-5
Abstract: Changes in environmental conditions can have strong energetic effects on animals through limited food availability or increased thermoregulatory costs. Especially difficult are periods of increased energy expenditures, such as reproduction. Reproductive female bats from the… read more here.

DOI: 10.1016/j.ygcen.2015.11.006
Abstract: We studied the interaction between torpor and reproduction in free-ranging female Tasmanian echidnas using a combination of techniques including urogenital smears, hormone analysis, ultrasonography, external temperature loggers and camera traps. Male echidnas initiated mating activity… read more here.

DOI: 10.1071/am19005
Abstract: Physiology and behaviour are closely linked, making knowledge of the interaction between species’ energetics and activities important when attempting to understand how animals function in the wild. I examined torpor use by western pygmy-possums (Cercartetus… read more here.

DOI: 10.1086/720273
Abstract: Although heterothermy is employed by species at a global level within the order of Chiroptera (bats), the possibility of torpor being expressed in bat species inhabiting warmer climate zones has been explored only in the… read more here.

Sticking Together: Energetic Consequences of Huddling Behavior in Hibernating Juvenile Garden Dormice

DOI: 10.1086/721184
Abstract: Hibernation, or multiday torpor, allows individuals to save energy via substantial reductions of metabolism and body temperature but is regularly interrupted by euthermic phases called arousals. Social thermoregulation, or “huddling,” can act in synergy with… read more here.

Torpor Does Not Influence Spatial Memory in Hibernating Golden-Mantled Ground Squirrels (Spermophilus [Callospermophilus] lateralis)
Sign Up to like & getrecommendations! Published in 2022 at "Physiological and Biochemical Zoology"
DOI: 10.1086/721185
Abstract: Mammalian hibernation in ground squirrels is characterized by periods of torpor wherein body temperature approaches ambient temperature and metabolism is reduced to as low as 1/100th of active rates. It is unclear how hibernation affects… read more here.

DOI: 10.1086/722477
Abstract: Torpor, the temporary reduction of metabolic rate and body temperature, is a common energy-saving strategy in endotherms. Because of their small body size and energetically demanding life histories, hummingbirds have proven useful for understanding when… read more here.

DOI: 10.1093/conphys/coy057
Abstract: Abstract Although wildfires are increasing globally, available information on how mammals respond behaviourally and physiologically to fires is scant. Despite a large number of ecological studies, often examining animal diversity and abundance before and after… read more here.

DOI: 10.1111/mec.14827
Abstract: Hibernation, the use of prolonged torpor to depress metabolism, is employed by mammals to conserve resources during extended periods of extreme temperatures and/or resource limitation. Mammalian hibernators arouse to euthermy periodically during torpor for reasons… read more here.

Energetics of migratory bats during stopover: a test of the torpor-assisted migration hypothesis
Sign Up to like & getrecommendations! Published in 2019 at "Journal of Experimental Biology"
DOI: 10.1242/jeb.196691
Abstract: ABSTRACT The torpor-assisted migration hypothesis posits that migration is facilitated in bats by the use of torpor during stopover roosting periods, and predicts that at stopover, bats regulate time in torpor facultatively so that daily… read more here.
