Bergmann’s rule states that, within species of mammals, individuals tend to be larger in cooler environments. However, the validity of the rule has been debated. We examined the relationship between size and latitude as well as size and temperature within various species of mammals. We also tested the idea that smaller mammals follow Bergmann’s rule more strongly than larger mammals, as expected if heat conservation is the cause of the rule. When all studies were included, the percentage of… Expand

Bergmann's rule in mammals: a cross-species interspecific pattern
TLDR
It is shown, in a dataset comprising 3561 mammal species from 26 orders, that while there is no significant correlation between latitude and body mass using conventional methods, this correlation is highly significant when the phylogenetic structure of the dataset is accounted for, thus supporting Bergmann's claim that the rule only applies to closely related species. Expand
On the validity of Bergmann's rule
TLDR
Bergmann’s rule is a valid ecological generalization for birds and mammals and studies using body mass and other surrogates in mammals and birds show the greatest tendency to adhere to it. Expand
Bergmann's rule and the mammal fauna of northern North America
TLDR
This work tests for the existence of Bergmann's rule in the mammals in northern North America, and investigates whether small- and large-bodied species show different spatial patterns of body size variation, and examines the adequacy of analyses to account for the spatial pattern using the residuals arising from the environmental models. Expand
An interspecific assessment of Bergmann’s rule in 22 mammalian families
TLDR
It is concluded that factors other than latitude and temperature are the major drivers of body mass evolution at the family level in mammals. Expand
Do amphibians follow Bergmann's rule?
It is not clear whether Bergmann's rule, larger size within species in cooler areas, holds for any group of ectotherms. Data are presented and used to test whether amphibians show body-size patternsExpand
Amphibians Do Not Follow Bergmann's Rule
TLDR
It is concluded that Bergmann's rule is not generally applicable to these taxa, and evolutionary explanations of Bergman's clines in other tetrapods need not account for unique life-history attributes of amphibians. Expand
No general relationship between mass and temperature in endothermic species
TLDR
The results suggest that Bergmann's rule is not general and temperature is not a dominant driver of biogeographic variation in mass, and the justification for the hypothesis that global warming could result in widespread decreases in body size is weakened. Expand
WHEN RENSCH MEETS BERGMANN: DOES SEXUAL SIZE DIMORPHISM CHANGE SYSTEMATICALLY WITH LATITUDE?
Abstract Bergmann's and Rensch's rules describe common large‐scale patterns of body size variation, but their underlying causes remain elusive. Bergmann's rule states that organisms are larger atExpand
WHEN RENSCH MEETS BERGMANN: DOES SEXUAL SIZE DIMORPHISM CHANGE SYSTEMATICALLY WITH LATITUDE?
TLDR
This work uses published studies of sex-specific latitudinal body size clines in vertebrates and invertebrates to investigate patterns equivalent to Rensch's rule among populations within species and to evaluate their possible relation to Bergmann's rule. Expand
Patterns of within-species body size variation of birds: strong evidence for Bergmann's rule
TLDR
This study gathers data on body size variation from the literature and uses two general meta-analytical procedures to test the validity of Bergmann's rule in birds: a modified vote-counting approach and calculation of overall effect sizes. Expand

Bergmann's rule is invalid
TLDR
If reduction in relative surface area is indeed an adaptation to conserve heat, then mammals should increase in size from south to north at rates two orders of magnitude greater than they do, and Bergmann's rule has no basis in fact or theory. Expand
Cope's rule, the island rule and the scaling of mammalian population density
TLDR
Results show that in mammals there is an optimum body size for energy acquisition at about 1 kg, and suggest a partial explanation for another widespread ecotypic pattern, the 'island rule': that on islands, small mammal species evolve to larger size and large species to smaller size. Expand
Why do European stoats Mustela erminea not follow Bergmann's rule?
TLDR
A positive correlation was found between the frequency distribution, by size, of available prey and stoat body size in the different areas examined, and this supports the hypothesis that body size variation in the stoat, especially females, is an adjustment to regional variations in the sizes of their available prey.

On the Ecological Significance of Bergmann's Rule
A positive correlation of weight with latitude in homoiotherms (Bergmann's rule) cannot normally depend upon the physics of heat exchange. Most latitudinally widespread mammals in North America doExpand
The Strategy of Body Size in Mammalian Carnivores
TLDR
Temperature and latitude are shown to be good predictors of body size in several species, but temperature does no better than latitude at predicting size. Expand
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. Expand
Natural selection on body size and proportions in house sparrows
TLDR
It is reported here further analyses indicating that sparrows also undergo selection for refinement of bodily proportions, consistent with predictions from Allen's ecogeographic rule. Expand

TLDR
The general correlation of size with latitude in homeothermic animals was first noted by C. Bergmann (1847), who held that thermoregulatory factors operate to bring about size clines, and subsequent work on this subject has taken three approaches. Expand
Litter size and latitude in North American mammals.
TLDR
To determine if this phenomenon of fluctuations of mammal populations in the higher latitudes of the northern hemisphere was evident in other mammals, a search was made of the literature concerning litter size of mammals of North America for the snowshoe hare and the opossum. Expand
Calibrating the paleothermometer: climate, communities, and the evolution of size
TLDR
Recent sizeGradients of mammals should be screened for the possibility of character displacement if fossil size gradients are to be used as a "paleothermometer" for past climate. Expand
