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
immature ixodes scapularis (acari: ixodidae) parasitizing lizards from the southeastern u.s.a.	preserved museum specimens of 13 lizard and 3 snake species common in the southeastern u.s.a. were examined for immature ixodes scapularis say ticks. five eumeces and 4 ophisaurus lizard species yielded an infestation prevalence of 17.8% for species of eumeces and 29.0% for species of ophisaurus. mean intensity of larvae and nymphs was 7.1 and 2.7, respectively, for species of eumeces, and 6.3 and 1.4, respectively, for species of ophisaurus. collection dates of the lizards ranged from january t ...	1993	8410539
