Bergmann’s Rule and Body Size in Mammals
@article{Freckleton2003BergmannsRA, title={Bergmann’s Rule and Body Size in Mammals}, author={Robert P. Freckleton and Paul H. Harvey and Mark Pagel}, journal={The American Naturalist}, year={2003}, volume={161}, pages={821 - 825} }
Aim: To describe the geographical pattern of mean body size of the non-volant mammals of the Nearctic and Neotropics and evaluate the influence of five environmental variables that are likely to affect body size gradients.
Location: The Western Hemisphere.
Methods: We calculated mean body size (average log mass) values in 110 × 110 km cells covering the continental Nearctic and Neotropics. We also generated cell averages for mean annual temperature, range in elevation, their interaction…

What determines conformity to Bergmann's rule?
- Environmental Science
- 2007
It is suggested that species with large geographical ranges are likely to encounter significant heterogeneity in those factors that influence body size, and are thus likely to exhibit size clines, and that the spatial distribution of key resources within the species range constitutes a significant predictor of carnivore body size.
Spatial patterns in the size of Chinese lizards are driven by multiple factors
- Environmental Science, GeographyEcology and evolution

It is found that the body size of Chinese lizards was larger in warmer regions, and it is established that at the assemblage level, size was correlated with multiple climatic factors, and that body size–climate correlations differed within the four major groups.
Geographic variation in body size: the effects of ambient temperature and precipitation

Primary production has an important effect on body size of several species of mammals, and the observed positive relationships between average minimum January temperature and body size in four of the six species influenced by rain further support this conclusion.
Global patterns of body size evolution are driven by precipitation in legless amphibians

It is argued that subterranean lifestyles minimize the effects of aboveground selection agents, making humidity a dominant selection pressure – aridity promotes larger body sizes that reduce risk of evaporative dehydration, while smaller sizes occur in wetter environments where dehydration constraints are relaxed.
LATITUDINAL AND CLIMATIC VARIATION IN BODY SIZE AND DORSAL SCALE COUNTS IN SCELOPORUS LIZARDS:A PHYLOGENETIC PERSPECTIVE
- Environmental ScienceEvolution; international journal of organic evolution
- 2011
Univariate analyses indicated phylogenetic signal for body size, scale counts, latitude, and all climate indicators; in all cases, phylogenetic regression models fit the data significantly better than nonphylogenetic models; thus, residuals for log10 number of dorsal scale rows exhibited phylogenetics signal.
Geographic and temporal correlations of mammalian size reconsidered: a resource rule

The correlation of mammalian size with geography and time reflects the impact of temperature, rainfall, and season on primary production, as well as the necessity in the case of some species to share resources with competitors.
Body size trends in response to climate and urbanization in the widespread North American deer mouse, Peromyscus maniculatus
- Environmental ScienceScientific Reports

A densely sampled, multi-source dataset to examine how climate and urbanization affect body size of Peromyscus maniculatus, an abundant rodent found across North America, finds PEMA mass, but not length, is decreasing over time irrespective of climate or population density.

Bergmann's rule and the mammal fauna of northern North America
- Environmental Science
- 2004
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.

Broad support is found for Bergmann’s rule as a general trend for mammals; however, the analyses do not support heat conservation as the explanation.

Latitude is a better predictor of size in erminea than available measures of climate, seasonality or prey size, and regional differences in the abundance of prey during the growth of young weasels may affect adult size much more in males than in females and contribute to geographic variation in sexual dimorphism.
