Migration distances of eight species of amphibians were studied at 14 sites in the Czech Republic in the course of the 2007 spring migration season. Drift fences with pit-fall traps were installed at varying distances from the reproduction pond. No substitute breeding ponds were available nearby. 4423 m of drift fence was installed and data from a total of 4823 specimens were collected. The estimate 95th percentile migration distances for the newts Lissotriton vulgaris, Mesotriton alpestris and Triturus cristatus were between 105-866 m, and for the frogs Bombina bombina, Bufo bufo, Rana arvalis and R. temporaria estimates were between 170-2214 m. No adult individuals of R. ridibunda were caught out of water. With two exceptions in B. bufo there were no significant among-site differences in migration distances between L. vulgaris, T. cristatus and B. bufo. There were no significant between-sex differences in migration distances of L. vulgaris, M. alpestris, T. cristatus, B. bufo and R. arvalis. Thanks to a great number of various sites processed simultaneously and by the same methodology, presented data provide information on the overall distribution of migration distances in different habitats. The results could be used for the estimation of the extent of the influence on amphibian populations in cases of transection or other habitat degradation in the vicinity of their reproduction ponds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
