Notes on a discrepancy in mitochondrial DNA and allozyme differentiation in a pond frog Rana nigromaculata.
Analyses of complete 1143-base pair sequence of the mitochondrial cytochrome b gene demonstrated a sister relationship between Japanese R. nigromaculata and Korean R. plancyichosenica, but not with Korean R. nigromaculata, while the allozyme data strongly supported the monophyly of the Korean and Japanese populations of R. nigromaculata. We surmise this discordance to be the result of the inher...
متن کاملPreferred Feeding Sites and Prey of the Adult Gold-spotted Pond Frog, Rana plancyi chosenica
To determine the feeding sites preferred by adult gold-spotted pond frogs, Rana plancyi chosenica, and the foods that induce favorable growth of the frogs in the laboratory, we conducted two separate experiments between 27 May and 12 July 2007 in a vivarium. In the first experiment, we counted the number of crickets eaten by four gold-spotted pond frogs in a 60 min period at four different feed...
متن کاملHabitat use and home range of the endangered gold-spotted pond frog (Rana chosenica).
Because of their complex life styles, amphibians and reptiles living in wetlands require both aquatic and terrestrial buffer zones in their protected conservation areas. Due to steep declines in wild populations, the gold-spotted pond frog (Rana chosenica) is listed as vulnerable by the IUCN. However, lack of data about its movements and use of habitat prevents effective conservation planning. ...
متن کاملComplete nucleotide sequence and gene rearrangement of the mitochondrial genome of the Japanese pond frog Rana nigromaculata.
In this study, we determined the complete nucleotide sequence of the mitochondrial genome of the Japanese pond frog Rana nigromaculata. The length of the sequence of the frog was 17,804 bp, though this was not absolute due to length variation caused by differing numbers of repetitive units in the control regions of individual frogs. The gene content, base composition, and codon usage of the Jap...
متن کاملAltitudinal variation in age and body size in Yunnan pond frog (Pelophylax pleuraden).
Large-scale systematic patterns of body size are a basic concern of evolutionary biology. Identifying body size variation along altitudinal gradients may help us to understand the evolution of life history of animals. In this study, we investigated altitudinal variation in body size, age and growth rate in Chinese endemic frog, Pelophylax pleuraden. Data sampled from five populations covering a...
