Data from: Long-term observation of amphibian populations inhabiting urban and forested areas in Yekaterinburg, Russia

This article present data derived from a 36 year-long uninterrupted observational study of amphibian populations living in the city and vicinity of Yekaterinburg, Russia. This area is inhabited by six amphibian species. Based on a degree of anthropogenic transformation, the urban territory is divided into five highly mosaic zones characterized by vegetation, temperature, and a distinctive water pollution profile. Population data contain year-by-year number of animals, sex ratio, and species-specific fecundity including number and quality of spawns. The data demonstrate that urbanization is detrimental to forest-specific amphibian species Salamandrella keyserligii and Bufo bufo and that urban niches are occupied by Rana arvalis, Lissotriton vulgaris, and Pelophylax ridibundus, which are, apparently, more resilient to environmental pollution. These data provide an excellent opportunity to assess urban environment from an animal population-wide perspective as well as to reveal forces driving animal adaptation to anthropogenic transformation of habitats.
