Summary 1 This review examines the intraspecific patterns and differences in life‐history
traits of amphibian populations living at different altitudes and latitudes. Specifically we …

Phylogenetic analysis of large datasets using complex nucleotide substitution models under
a maximum likelihood framework can be computationally infeasible, especially when …

Thermal constraint on energy assimilation is an important source of life history variation in
geographically widespread ectotherms such as the eastern fence lizard (Sceloporus …

I present a dynamic bioenergetic model that couples individual energetics and population
dynamics to predict current lizard ranges and those following climate warming. The model …

Temperature influences the activity seasons, reproductive phenology, survival rates, and
growth rates of lizards. We present a model of lizard growth that predicts phenotypic patterns …

The generality and causes of Bergmann's rule have been debated vigorously in the last few
years, but Bergmann's clines are rarely explained in the context of life-history theory. We …

Female‐biased sexual size dimorphism is uncommon among vertebrates and traditionally
has been attributed to asymmetric selective pressures favoring large fecund females (the …

Variation in thermal constraints on activity has been hypothesized to be an important
ecological source of geographic variation in growth rates of juvenile eastern fence lizards …

In geographically widespread ectotherms, variation in life history phenotypes may be
caused by differences in maintenance metabolism of individuals. I estimated daily and …

Studies of reproductive effort in ectotherms have focused primarily on the energetic
investment in gamete production; much less is known about the indirect energetic costs of …
