Latitudinal clines in an ectothermic vertebrate: Patterns in body size, growth rate, and reproductive effort suggest countergradient responses in the prairie lizard

We assessed body size, growth rates, and reproductive traits for prairie lizard (S. consobrinus) populations along the latitudinal thermal gradient and compared body size clines between S. consobrinus and eastern fence lizard (Sceloporus undulatus) populations.
