Species limits and phylogeography of North American cricket frogs (Acris: Hylidae).
Cricket frogs are widely distributed across the eastern United States and two species, the northern cricket frog (Acris crepitans) and the southern cricket frog (A. gryllus) are currently recognized. We generated a phylogenetic hypothesis for Acris using fragments of nuclear and mitochondrial genes in separate and combined phylogenetic analyses. We also used distance methods and fixation indice...
متن کاملA new species of Myxidium (Myxosporea: Myxidiidae), from the western chorus frog, Pseudacris triseriata triseriata, and Blanchard's cricket frog, Acris crepitans blanchardi (Hylidae), from eastern Nebraska: morphology, phylogeny, and critical comments on amphibian Myxidium taxonomy.
During March 2001-April 2004, 164 adult anurans of 6 species (47 Rana blairi, 35 Rana catesbeiana, 31 Hyla chrysoscelis, 31 Pseudacris triseriata triseriata, 11 Bufo woodhousii, and 9 Acris crepitans blanchardi) from Pawnee Lake, Lancaster County, Nebraska, were surveyed for myxozoan parasites. Of these, 20 of 31 (65%) P. triseriata triseriata and 1 of 9 (11%) A. crepitans blanchardi were infec...
متن کاملDifferential jumping performance in newly metamorphosed Blanchard’s cricket frogs, Acris blanchardi (Anura: Hylidae), from fish- and invertebrate-dominated ponds
Differential jumping performance in newly metamorphosed Blanchard’s cricket frogs Acris blanchardi (Anura: Hylidae) from fishand invertebrate-dominated ponds. Organisms that adopt phenotypically plastic anti-predator strategies during larval stages may incur fitness costs later in development. These costs are typically difficult to define in many species. The difficulty of identifying ecologica...
متن کاملForms and prevalence of intersexuality and effects of environmental contaminants on sexuality in cricket frogs (Acris crepitans).
Cricket frogs (Acris crepitans) from several different sites in Illinois were collected to assess the effects of environmental contamination on the prevalence of intersex gonads. Of 341 frogs collected in 1993, 1994, and 1995, 2.7% were intersex individuals. There was no statistically significant relationship between the chemical compounds detected and cricket frog intersexuality. However, ther...
متن کاملPhysiological Trade-offs between Immunity and Reproduction in the Northern Cricket Frog (acris Crepitans)
Investigations of natural history trade-offs between reproduction and immunity are common throughout the literature. Most previous studies of such trade-offs have focused on how resources can be drawn from immune response to fuel reproduction. Our results demonstrate that resources also can be shifted from reproduction to immunity. Immunologically-challenged male northern cricket frogs (Acris c...
