Abstract
In Lake Glubokoe, the Amphibia are represented by five species. Two numerous species, Rana temporaria L. and Bufo bufo L., spawn in the lake and appear to be a significant component of its ecosystem. Thus, in autumn R. temporaria is a common food for predatory fish (pike, perch). During their wintering R. temporaria participate in the consumption of oxygen from the water. They may be a source of dangerous infections. Their tadpoles and those of B. bufo feed in the lake and annually remove substances from it. Adult R. temporaria in autumn, and the young of the year of R. temporaria and of B. bufo influence the population numbers of small littoral invertebrates. Several dozen pairs of Rana terrestris Andrzejw are observed to spawn regularly. Rana esculenta L. and Rana ridibunda Pallas are scarce. The influence of introducing a nature preserve on the numbers of Amphibia in Lake Glubokoe is discussed.
