| 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 |
| patterns of infection of the lizard malaria parasite, plasmodium floridense, in invasive brown anoles (anolis sagrei) in southwestern florida. | plasmodium floridense is a saurian malaria parasite common in the anolis lizards of the northern caribbean islands and the se usa. in the latter area, it is found in two native lizards (sceloporus undulatus and anolis carolinensis) and in the introduced anolis sagrei, which is native to cuba. we measured parasite prevalence and parasitemia in the introduced anole at a single site in north port, florida over 5 years. prevalence, based on microscopic examination of blood smears, was high year-roun ... | 2009 | 19085004 |
| transmission, host specificity, and seasonal occurrence of cyrtosomum penneri (nematoda: atractidae) in lizards from florida. | experimental infections and field-collected lizards were used to investigate issues of transmission, host specificity, and seasonal occurrence in the nematode cyrtosomum penneri (cosmocercoidea: atractidae). anolis sagrei (87 males, 42 females) were captured from the florida southern college campus, polk county, florida, from october 2010 to september 2011, and 8,803 c. penneri were collected from their intestines. during the breeding season all sexually mature (svl ≥ 34 mm) a. sagrei were infec ... | 2013 | 23020090 |
| 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 |
