Bergmann’s Rule in Ectotherms: A Test Using Freshwater Fishes

Understanding patterns of variation in body size within and among species is a central question in evolutionary ecology. To provide information on patterns of intraspecific body size variation among vertebrate ectotherms, and to test for compliance with Bergmann's rule, Belk and Houston compile...

Description
Summary:Understanding patterns of variation in body size within and among species is a central question in evolutionary ecology. To provide information on patterns of intraspecific body size variation among vertebrate ectotherms, and to test for compliance with Bergmann's rule, Belk and Houston compiled data for several species of freshwater fishes of North America.
