latitudinal and seasonal variation in reproductive effort of the eastern fence lizard (sceloporus undulatus).	geographic variation in life-history traits among populations of wide-ranging species is influenced by both spatial and temporal aspects of the environment. rarely, however, are the effects of both aspects examined concurrently. we collected gravid female lizards (sceloporus undulatus) from northern (indiana), central (mississippi) and southern (florida) populations, spanning nearly the full latitudinal range of the species, to examine among population differences in strategies of reproductive e ...	2014	24148228
convergent evolution of embryonic growth and development in the eastern fence lizard (sceloporus undulatus).	theory predicts that cold environments will select for strategies that enhance the growth of ectotherms, such as early emergence from nests and more efficient use of resources. we used a common garden experiment to detect parallel clines in rates of embryonic growth and development by eastern fence lizards (sceloporus undulatus). using realistic thermal conditions, we measured growth efficiencies and incubation periods of lizards from five populations representing two distinct clades. in both cl ...	2006	16817545
