It has been argued that environmental seasonality selects for larger body size among homeotherms (Brodie 1975; Downhower 1976; Boyce 1979). Indeed, strong correlations between body size and seasonality have been shown both within species of mammals (Brodie 1975; Boyce 1978) and among mammal faunas (Zeveloff 1982). Because of high mortality during the season of resource shortage. surviving individuals enjoy low competition and abundant resources during the growth season. Selection then favors… 
Fasting endurance and the evolution of mammalian body size
TLDR
Diversity of environmental correlates of body size among mammalian carnivores suggested that 'homeostatic needs' might set a lower limit to body size at higher latitudes suggests that large size reflects the need for energy reserves during the fasting period.
How foraging allometries and resource dynamics could explain Bergmann's rule and the body-size diet relationship in mammals
TLDR
A model that may explain Bergmann's rule and the inverse relationship between herbivore body size and diet quality is presented, and the inclusion of consumer–resource dynamics predicts both.
Energetics and the evolution of body size in small terrestrial mammals
TLDR
In wood mice, Apodemus syluaticus, a correlation between basal metabolic rate (BMR) and the thermogenic capacity (noradrena­ line-induced metabolic rate) is found, which indicates a more complex involvement of energetics in the phenomenon of overwinter survivorship than is addressed by models of energy balance alone.
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.
SEASONAL AND INTERANNUAL VARIATION IN THE ALLOMETRY OF ENERGY ALLOCATION IN JUVENILE STRIPED BASS
TLDR
The results indicate that energy allocation patterns result from interactions among season, ontogenetic stage, and body size, and the variation in growth, allocation, and severity of the winter energy deficit likely interact to determine first-winter survival.
Effect of energetic constraints on distribution and winter survival of weasel males.
TLDR
An energetic model predicting how individuals of different size are able to balance their energy budgets feeding on large and small prey while minimizing time spent hunting, thereby reducing their own exposure to predation is constructed.
Long-term morphological changes in the skeleton of red deer (Artiodactyla, Cervidae) at its northern periphery
TLDR
The size of teeth was reduced as much as, or even more than, the size of weight-bearing bones, which indicates an evolutionary response rather than phenotypic plasticity to changing forage and environmental conditions.
Size matters: the (negative) allometry of copulatory duration in mammals
TLDR
It is suggested that small mammals may find the sustained maneuvering and body positioning of copulation easier than do large mammals, and this hypothesis is supported by an apparently isometric relationship between duration of copulating and ratio of power to mass.
BODY MASS AND ENVIRONMENT: A STUDY IN NEGEV RODENTS
Seasonal body mass change in rodents could be due to: (1) an adaptive strategy that reduces energy requirements during unfavorable seasons and (2) a response to fluctuations in food resources. We
Optimal Body Size and Energy Expenditure during Winter: Why Are Voles Smaller in Declining Populations?
TLDR
A model predicting optimal wintering body size is formulated, accounting for the scaling of both energy expenditure and assimilation to body size, and the trade‐off between survival benefits of a large size and avoiding survival costs of foraging.

Cetacean Energetics, an Overview of Intraspecific Size Variation
TLDR
The adult body size within species is inversely correlated with the length of the feeding season and directly correlated with prey availability during that period, as differences in diversity of prey and/or their year-round availability become less marked between hemispheres.
Body Size, Physiological Time, and Longevity of Homeothermic Animals
TLDR
Life span, like the other scales of physiological time, may be regarded, not as a direct product of natural selection, but rather as an allometric consequence of other characteristics subjected to natural selection.
Size, life history and ecology in mammals
TLDR
It is argued that because size scales the main life history parameters of mammals it should also be a central theme in ecology from the individual to the community level of organisation and develop a broader biological synthesis in which genetic and physiological determinants will inevitably feature more centrally in ecological and behavioural theory.
BERGMANN'S RULE AND CLIMATIC ADAPTATION IN WOODRATS (NEOTOMA)
TLDR
Data on the temperature regulation of representatives of 10 populations of woodrats permits a direct evaluation of the relationships between metabolism, heat loss, body size, and environmental temperature, and indicate the major avenues of climatic adaptation in this group of rodents.

TLDR
A model to investigate the effects of density-dependent resource availability on per capita population growth rate is presented and seasonality appears to be a very important factor in the evolution of large body size, especially in homeothermic vertebrates.

TLDR
Whether a trend towards larger sizes in cool regions may be found when comparisons are made between whole faunas of poikilotherm vertebrates, including quite un- un-cool regions is examined.
The Effects of Size and Phylogeny on Patterns of Covariation in the Life History Traits of Lizards and Snakes
TLDR
Analysis of the impact of size and lineage on patterns of covariation in the life history traits of reptiles suggests that microevolutionary explanations are not sufficient to account for the patterns in the data.
The influence of size and phylogeny on patterns of covariation among life-history traits in the mammals
Do size and phylogeny affect patterns of covariation in life-history traits? If there are phylogenetic constraints on the evolution of life histories, do they differ from lineage to lineage? I
Energetics and Water Economy of the Smallest Desert Mammal
TLDR
The kidney medullary thickness of the desert shrew is high, suggesting a considerable urine concentrating ability and only scant urinary water losses, which means the Desert shrew can maintain water balance without drinking even when some water is required for thermoregulation.
