Quantifying energetic and fitness consequences of seasonal heterothermy in an Arctic ungulate [PDF]

open access: yesEcology and Evolution, 2021
Animals have adapted behavioral and physiological strategies to conserve energy during periods of adverse conditions. Heterothermy is one such adaptation used by endotherms.

Heterothermy in a Small Passerine: Eastern Yellow Robins Use Nocturnal Torpor in Winter

open access: yesFrontiers 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.

Heterothermy as a mechanism to offset energetic costs of environmental and homeostatic perturbations [PDF]

open access: yesScientific Reports, 2021
Environmental and biotic pressures impose homeostatic costs on all organisms. The energetic costs of maintaining high body temperatures (T b) render endotherms sensitive to pressures that increase foraging costs.

Torpor on demand: heterothermy in the non-lemur primate Galago moholi. [PDF]

open access: yesPLoS ONE, 2010
Hibernation and daily torpor are energy- and water-saving adaptations employed to survive unfavourable periods mostly in temperate and arctic environments, but also in tropical and arid climates.

Precocious Torpor in an Altricial Mammal and the Functional Implications of Heterothermy During Development

open access: yesFrontiers in Physiology, 2019
Most mammals and birds are altricial, small and naked at birth/hatching. They attain endothermic thermoregulation at a fraction of their adult size at a vulnerable stage with high heat loss when many could profit from using torpor for energy conservation.

The importance of temporal heterothermy in bats [PDF]

open access: yesJournal of Zoology, 2014
AbstractAnimals must balance their energy budgets even when confronted with periodic food shortages and/or adverse environmental conditions. Especially, small endothermic animals require large amounts of energy to maintain high and stable body temperatures (Tb) via endogenous heat production. To deal with energetic challenges, many small endotherms are

Mitochondrial polymorphism m.3017C>T of SHLP6 relates to heterothermy

open access: yesFrontiers in Physiology, 2023
Heterothermic thermoregulation requires intricate regulation of metabolic rate and activation of pro-survival factors. Eliciting these responses and coordinating the necessary energy shifts likely involves retrograde signalling by mitochondrial-derived ...

Heterothermy use in winter is associated with reduced litter size during following breeding season

open access: yesFrontiers in Ecology and Evolution
Heterothermy is considered to be the most effective energy-saving strategy improving survival under natural conditions. Interspecific studies suggest that this strategy is also associated with reduced reproductive output.

Extreme regional heterothermy during flight in diverse wild bats

open access: yesiScience
Summary: Endotherms actively regulate their body temperatures to maintain relatively constant internal temperatures in heterogeneous environments, but experience regional variation in body temperature (heterothermy). This is especially pronounced in bats,

Heterothermy and antifungal responses in bats

open access: yesCurrent Opinion in Microbiology, 2021
(Uploaded by Plazi for the Bat Literature Project) Hibernation, a period where bats have suppressed immunity and low body temperatures, provides the psychrophilic fungus Pseudogymnoascus destructans the opportunity to colonise bat skin, leading to severe disease in susceptible species.
