Timing of winter phenotype expression determines individual chances of survival until the next reproductive season. Environmental cues triggering this seasonal phenotypic transition have rarely been investigated, although they play a central role in the compensation of climatic fluctuations via plastic phenotypic adjustments. Initiation of winter daily torpor use—a widespread energy-saving phenotype—could be primarily timed according to anticipatory seasonal cues (anticipatory cues hypothesis… 
Flexibility Is Costly: Hidden Physiological Damage From Seasonal Phenotypic Transitions in Heterothermic Species
TLDR
New perspectives to be considered when analyzing adaptation to seasonality, and a list of putative costs, including DNA damage, inflammatory response to fat load, brain and cognitive defects, digestive malfunction and immunodeficiency, that should receive more attention in future research on physiological seasonality are proposed.
Sex-Specific Response to Caloric Restriction After Reproductive Investment in Microcebus murinus: An Integrative Approach
TLDR
It is hypothesized that females could have greater capacity to survive harsh conditions than males, considering the temporal shift in their respective reproductive energy investment, which can challenge them differently, as well as enhanced flexibility in females' physiological regulation.
Why be thrifty? Sex-specific heterothermic patterns in wintering captive Microcebus murinus do not translate into differences in energy balance
TLDR
Male and female differences in a mouse lemur model (Microcebus murinus) are assessed, studying their physiological flexibility toward caloric restriction, and examining the impact on their reproductive success, which may emphasize the existence of other benefits of heterothermic responses than fat reserves.
A Mesocosm Experiment in Ecological Physiology: The Modulation of Energy Budget in a Hibernating Marsupial under Chronic Caloric Restriction
TLDR
This study shows that the use of torpor can be modulated depending on energy supply, thus optimizing energy budgeting and suggesting that hibernation is a powerful strategy to modulate energy expenditure in mammals from temperate regions.
A new cue for torpor induction: charcoal, ash and smoke
TLDR
Torpor expression is enhanced in yellow-footed antechinus in response to a combination of fire cues (food restriction, smoke and a charcoal/ash substrate), indicating a previously unrecognised regulatory mechanism for thermal biology in mammals.
Individual variation in energy‐saving heterothermy affects survival and reproductive success
TLDR
The results support the hypothesis that fluctuating selection maintains heterothermic diversity and suggest that individualized eco-physiology can contribute to a more thorough understanding of the evolution of energy-saving strategies in endotherms.
The Torpid State: Recent Advances in Metabolic Adaptations and Protective Mechanisms†
TLDR
The flexibility of torpor use as an adaptive strategy enables different heterothermic species to substantially suppress their energy needs during periods of severely reduced food availability, and the torpor phenotype implies marked metabolic adaptations from the whole organism down to cellular and molecular levels.
Summer and fall ants have different physiological responses to food macronutrient content.
Heterothermy as the Norm, Homeothermy as the Exception: Variable Torpor Patterns in the South American Marsupial Monito del Monte (Dromiciops gliroides)
TLDR
The results confirm that this marsupial expresses a dynamic form of torpor that progresses from short torpor to hibernation as daylength shortens, and add to a growing body of evidence characterizing tropical and sub-tropical heterothermy as a form of opportunistic torpor.
Effects of Sex and Age on Heterothermy in Goodman’s Mouse Lemur (Microcebus lehilahytsara)
TLDR
Winter activity in a captive population of Microcebus lehilahytsara, Goodman’s mouse lemur, in a large enclosure at Zoo Zürich, Switzerland is studied to determine how this behavior varies with sex and age, and what this pattern suggests about the ultimate cause of torpor use in this clade.

Physiological flexibility and acclimation to food shortage in a heterothermic primate
TLDR
The first experimental evidence of different temporal levels of flexibility of energy-saving mechanisms in a heterotherm exposed to food shortage is provided, suggesting the flexible control of energy expenditure conferred by heterothermy may facilitate the plastic response of heterothermic species to more frequent climatic hazards.
Field evidence for a proximate role of food shortage in the regulation of hibernation and daily torpor: a review
TLDR
Evidence on the proximate role of food availability in heterothermy regulation by endotherms is reviewed, and alternative hypotheses that remain to be tested are emphasized.

TLDR
Future integrated studies are required to assess the scope for flexibility in life-history strategies as this will have a critical bearing on whether birds can adapt sufficiently rapidly to anthropogenic environmental changes, in particular climate change.
Intermediate-duration day lengths unmask reproductive responses to nonphotic environmental cues.
Many animals time their breeding to the seasons, using the changing day length to forecast those months when environmental conditions favor reproductive success; in Siberian hamsters (Phodopus
Chronic food shortage and seasonal modulations of daily torpor and locomotor activity in the grey mouse lemur (Microcebus murinus).
TLDR
Daily torpor allows M. murinus to face moderate food shortage whatever the photoperiod but poorly mitigates energy imbalance during severe food deprivation, especially under LD exposure, although the behavioral thermoregulation role warrants further investigation.
The Role of Energy Availability in Mammalian Hibernation: An Experimental Test in Free‐Ranging Eastern Chipmunks
TLDR
The results indicate that reduced torpor expression by hibernators can result from an absence of energetic necessity rather than a lack of physiological capability and suggest that even endotherms sequestered in a hibernaculum may benefit from maintaining an elevated body temperature whenever possible.
The Role of Energy Availability in Mammalian Hibernation: A Cost‐Benefit Approach
TLDR
It is suggested that trade‐offs between the benefits of energy conservation and the physiological costs of metabolic depression can explain both why hibernators periodically arouse from torpor and why they should use available energy to minimize the depth and duration of their torpor bouts.
Torpor use during gestation and lactation in a primate
TLDR
This study provides the first evidence that a heterothermic primate can use torpor to compensate for food shortages even during reproduction, and likely evolved as a response to climate-driven fluctuations in food availability in Madagascar.

TLDR
It is concluded that torpor use promotes fattening in late-born juvenile dormice prior to hibernation, providing the first evidence for a functional link between time spent in euthermy and ageing processes over winter.
Climate and resource determinants of fundamental and realized metabolic niches of hibernating chipmunks.
TLDR
The fundamental metabolic niche of hibernating chipmunks in cold environments is broad and constrained by climate, whereas the realized metabolic niche is highly variable among individuals and years and is determined primarily by local resource abundance.
