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.

Wellcome Open Research, 2022 Torpor is a hypothermic, hypoactive, hypometabolic state entered into by a wide range of animals in response to environmental challenge. This review summarises the current understanding of torpor.

Norepinephrine controls both torpor initiation and emergence via distinct mechanisms in the mouse. [PDF]
PLoS ONE, 2008 Some mammals, including laboratory mice, enter torpor in response to food deprivation, and leptin can attenuate these bouts of torpor. We previously showed that dopamine beta-hydroxylase knockout (Dbh -/-) mice, which lack norepinephrine (NE), do not ...

Txnip, Tanycytes, and Torpor [PDF]
Endocrinology, 2013 As biologists, we are brought up with the concept that mammals are homeothermic, so they tightly regulate body temperature through a complex balance between thermogenesis and heat conservation and dissipation mechanisms. One of the remarkable features of the natural world is that many mammals can also show torpor or hibernation.

Sulfide metabolism and the mechanism of torpor [PDF]
Journal of Experimental Biology, 2021 ABSTRACT Hibernation is a powerful response of a number of mammalian species to reduce energy during the cold winter season, when food is scarce. Mammalian hibernators survive winter by spending most of the time in a state of torpor, where basal metabolic rate is strongly suppressed and body temperature comes closer to ambient ...

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.

Biology Open, 2022 Torpor is a state of controlled reduction of metabolic rate (M) in endotherms. Assigning measurements of M to torpor or euthermy can be challenging, especially when the difference between euthermic M and torpid M is small, in species defending a high ...
