In the natural environment, hibernating sciurids generally remain dormant during winter and enter numerous deep torpor bouts from the time of first immergence in fall until emergence in spring. In contrast, black‐tailed prairie dogs (Cynomys ludovicianus) remain active throughout winter but periodically enter short and shallow bouts of torpor. While investigating body temperature (Tb) patterns of black‐tailed prairie dogs from six separate colonies in northern Colorado, we observed one… 
Latitudinal Differences in the Hibernation Characteristics of Woodchucks (Marmota monax)
TLDR
Differences in hibernation characteristics of three free‐ranging populations of woodchucks distributed along a latitudinal gradient from Maine to South Carolina revealed a direct relationship between latitude and total time spent in torpor, and the “cost‐benefit” hypothesis of hibernation may help to explain these results.
Daily torpor and hibernation in birds and mammals

TLDR
The analysis strongly supports the view that hibernators and daily heterotherms are functionally distinct groups that probably have been subject to disruptive selection.
Phenology of hibernation and reproduction in ground squirrels: integration of environmental cues with endogenous programming
Mammalian hibernation is characterized by prolonged dormancy consisting of pronounced depression of metabolism and body temperature. Though hibernation occurs in at least seven mammalian orders and
Variation in phenology of hibernation and reproduction in the endangered New Mexico meadow jumping mouse (Zapus hudsonius luteus)
TLDR
Analysis of the timing of hibernation and reproduction in the federally endangered New Mexico meadow jumping mouse (Zapus hudsonius luteus), which occurs across a broad range of latitudes and elevations in the American Southwest, supported predictions for later emergence and shorter active intervals in montane populations relative to lower elevation valley populations.
Daily rhythms of body temperature and activity in free-living Black-tailed Tree Rats (Thallomys nigricauda) along an aridity gradient
TLDR
It is suggested that the energy savings in Tree Rats are a result of a combination of physiological and behavioural mechanisms allowing them to maintain nocturnal activity in winter and overall energy balance.
Winter body temperature patterns in free-ranging Cape ground squirrel, Xerus inauris: no evidence for torpor
TLDR
There was no evidence for daily torpor or pronounced hypothermia during the inactive phase, and mean minimum inactive phase Tb was 35.7 ± 0.3°C for non-lactating individuals.
Body Mass and Tail Girth Predict Hibernation Expression in Captive Dwarf Lemurs
TLDR
Assessment of torpor expression in captive dwarf lemurs, primates that are obligate, seasonal, and tropical hibernators, suggests that individuals optimize rather than maximize torpor according to body mass.
Physiological, Behavioral, and Life-History Adaptations to Environmental Fluctuations in the Edible Dormouse
TLDR
Dormice respond to short-term drops in ambient temperature by increased use of daily torpor as well as by huddling in groups of up to 24 conspecifics, which helps to balance individual predation risk against reproductive success and adds another layer of complexity to the ability to make flexible adjustments in this species.
Effects of aging on timing of hibernation and reproduction
TLDR
It is concluded that hibernation has to be viewed not merely as an energy saving strategy under harsh climatic conditions, but as an age-affected life-history trait that is flexibly used to maximize fitness.
Energetics meets sexual conflict: The phenology of hibernation in Tasmanian echidnas
TLDR
Comparisons with other echidna populations suggest that a decreased activity period due to hibernation has not increased male–male competition, and similar competition between groups of males for access to females is seen in chlamyphorid armadillos, which occupy a similar ecological niche to echidnas.

VARIATION IN TORPOR PATTERNS OF FREE-RANGING BLACK-TAILED AND UTAH PRAIRIE DOGS ACROSS GRADIENTS OF ELEVATION
TLDR
Both black-tailed and Utah prairie dogs displayed significant differences in Tb patterns across elevations, with lower elevation populations entering more shallow and infrequent torpor than Prairie dogs at higher elevations.
FACULTATIVE TORPOR IN FREE-RANGING BLACK-TAILED PRAIRIE DOGS (CYNOMYS LUDOVICIANUS)
TLDR
It is demonstrated that facultative torpor occurs in free-ranging black-tailed prairie dogs in the field and that Precipitation was not associated with entry into or arousal from torpor.
The role of dietary fatty acids in the evolution of spontaneous and facultative hibernation patterns in prairie dogs
TLDR
While high PUFA diets can enhance hibernation by these species, it does not appear to explain the differences between spontaneous and facultative strategies.
Sexual differences in over-winter torpor patterns of Richardson's ground squirrels in natural hibernacula
SummaryOver-winter torpor patterns of Richardson's ground squirrels hibernating in southern Alberta were monitored with temperature-sensitive radiocollars to determine if these patterns differed
Winter body fat, food consumption and nonshivering thermogenesis of representative spontaneous and facultative hibernators: The white-tailed prairie dog and black-tailed prairie dog
TLDR
It is concluded that the lack of spontaneous hibernation in the black-tailed prairie dog may be a derived characteristic, divergent from the condition in the ancestral stock, however, the genetically controlled ‘sliding’ body weight set-point remains similar to that of the hibernating white-tailed Prairie dog, a representative of the presumed ancestral condition.
Hibernating patterns of free-ranging Columbian ground squirrels
TLDR
Adult males began hibernation earlier, were euthermic for a greater proportion of the hibernating season and emerged earlier than other age and sex classes and the benefits offsetting these costs may be increased reproductive potential in spring and avoidance of predation in late summer.
Effects of cold exposure and dehydration on renal function in black-tailed prairie dogs.
TLDR
Black-tailed prairie dogs were deprived of food and water for several weeks during the fall and winter in a cold-room hibernaculum, and for several days at room temperature during the summer, and had lower urine and plasma osmotic concentrations than active animals.
Body temperature patterns in black-tailed prairie dogs in the field
TLDR
Body temperatures (Tb) of black-tailed prairie dogs were monitored in the field for 1 year and a daily and annual Tb patterns observed result in energy and water savings.
Comparison of hibernation, estivation and daily torpor in the edible dormouse, Glis glis
TLDR
All three forms of dormancy are based on the same physiological mechanism of thermal and metabolic regulation, including hibernation and estivation in winter and summer respectively.
Persistence of circadian rhythmicity in hibernating ground squirrels.
TLDR
This study confirms previous speculation about the persistence of circadian rhythms in golden-mantled ground squirrels during deep hibernation and demonstrates that the circadian system is involved in the timing of periodic arousals from hibernation.
