Cardiovascular changes during daily torpor in the laboratory mouse.
Am J Physiol Regul Integr Comp Physiol, 2009 The laboratory mouse is a facultative daily heterotherm in that it experiences bouts of torpor under caloric restriction. Mice are the most frequently studied laboratory mammal, and often, genetically modified mice are used to investigate many physiological functions related to weight loss and caloric intake.

Frontiers in Physiology, 2021 Hibernation (i.e., multiday torpor) is considered an adaptive strategy of mammals to face seasonal environmental challenges such as food, cold, and/or water shortage.

Reversal of the adipostat control of torpor during migration in hummingbirds
eLife, 2021 Many small endotherms use torpor to reduce metabolic rate and manage daily energy balance. However, the physiological ‘rules’ that govern torpor use are unclear.

Long-term survival, temperature, and torpor patterns
Scientific Reports, 2023 Mammalian and avian torpor is highly effective in reducing energy expenditure. However, the extent of energy savings achieved and thus long-term survival appear to differ between species capable of multiday hibernation and species restricted to daily ...

Heterothermy in a Small Passerine: Eastern Yellow Robins Use Nocturnal Torpor in Winter
Frontiers in Ecology and Evolution, 2021 Torpor is a controlled reduction of metabolism and body temperature, and its appropriate use allows small birds to adapt to and survive challenging conditions.

Hibernation and daily torpor in Australian mammals [PDF]
Australian Zoologist, 2010 Trpor is the most effective means for energy conservation available to mammals and is characterized by substantial reductions in body temperature (Tb) and metabolic rate (MR). Most Australian terrestrial mammals are small with high mass-specific energy requirements and, although it is widely believed that torpor is not needed in a ‘warm’ country like ...

FEBS Open Bio, 2022 The energy‐saving strategy of Djungarian hamsters (Phodopus sungorus, Cricetidae) to overcome harsh environmental conditions comprises of behavioral, morphological, and physiological adjustments, including spontaneous daily torpor, a metabolic downstate.

On the modulation and maintenance of hibernation in captive dwarf lemurs
Scientific Reports, 2021 In nature, photoperiod signals environmental seasonality and is a strong selective “zeitgeber” that synchronizes biological rhythms. For animals facing seasonal environmental challenges and energetic bottlenecks, daily torpor and hibernation are two ...

Naturwissenschaften, 2013 Hibernation and daily torpor are two distinct forms of torpor, and although they are related, it is not known how and in which sequence they evolved. As the pattern of torpor expressed by the oldest marsupial order the opossums (Didelphimorphia) may provide insights into the evolution of torpor, we aimed to provide the first quantitative data on the ...
