Abstract The white-tailed prairie dog is a spontaneous hibernator which commences deep torpor bouts during early fall while the black-tailed prairie dog is a facultative hibernator that will only enter shallow torpor when stressed by cold and food deprivation. Plant oils rich in polyunsaturated fatty acids (PUFAs) enhance the duration and depth of mammalian torpor. Thus, we tested the hypothesis that black-tailed prairie dogs sampled in the field have less PUFAs in their diets and that the… Expand
Dietary Fatty Acid Composition and the Hibernation Patterns in Free‐Ranging Arctic Ground Squirrels
This study is the first to demonstrate that estimated dietary PUFA levels of a free‐ranging hibernator influence subsequent torpor patterns, and found that the PUFA contents of fall diets varied more than threefold among individuals. Expand
The effect of body mass and diet composition on torpor patterns in a Malagasy primate (Microcebus murinus)
The propensity of animals to enter torpor is directly influenced by age and seasonal changes in body mass, and thus reflect important physiological aspects of flexible thermoregulatory responses. Expand
Effect of dietary fatty acids on metabolic rate and nonshivering thermogenesis in golden hamsters.
It is suggested that the increased capacity for NST in PUFA-supplemented hamsters enables them lower RMR below the lower critical temperature of the thermoneural zone. Expand
Changes in diet, body mass and fatty acid composition during pre-hibernation in a subtropical bat in relation to NPY and AgRP expression
It is suggested that the increase in expression levels of NPY and AgRP may contribute to the observed diet shift and mass gain, and that the FA composition of the bat’s specialized diet is adaptive in the relatively high temperatures the authors recorded in both their winter and summer roosts.

The role of polyunsaturated fatty acids in the expression of torpor by mammals: a review.
It is argued that alternate mechanisms exist for maintaining the fluidity of body fats and that high-PUFA intake may not be a prerequisite for deep and extended bouts of torpor and that animals attempt to optimize rather than maximize PUFA intake. Expand
Seasonal changes in lipids, diet, and body composition of free-ranging black-tailed prairie dogs (Cynomys ludovicianus)
Seasonal changes in fat, lean, and total body mass indicate that black-tailed prairie dogs lack the lipids necessary for hibernation. Expand
Effects of dietary polyunsaturated fatty acids on mitochondrial metabolism in mammalian hibernation
The reduced mitochondrial proton leak in the 15, 35 and 55 mg g–1 18:2 diet groups might compensate for the inability to suppress respiration, permitting whole-animal energy savings over the hibernation season. Expand
Extreme Plasticity in Thermoregulatory Behaviors of Free‐Ranging Black‐Tailed Prairie Dogs
This study provides a rare example of extreme plasticity in thermoregulatory behaviors of free‐ranging prairie dogs and provides evidence contrary to models that propose a clear delineation between homeothermy, facultative torpor, and hibernation. Expand
Avoidance of Skeletal Muscle Atrophy in Spontaneous and Facultative Hibernators
It appears that regardless of the phenotypic expressions of hibernation, the outcome is the conservation of skeletal muscle in the winter season of reduced activity and food intake. Expand
Diet affects resting, but not basal metabolic rate of normothermic Siberian hamsters acclimated to winter.
Results indicate that in mealworm-fed hamsters energy expenditure in the cold is lower than in animals eating a seed-supplemented diet, and that the degree of FA unsaturation of diet affects energetics of heterotherms, not only during torpor, but also during normothermy. Expand
