Abstract

The effect of beaver (Castor fiber Linnaeus, 1758) activity on amphibian reproduction was studied in the small river valleys in Novgorod oblast. At sites not subjected to beaver activity, the reproduction rate of amphibians was low. In spring the water in beaver ponds warms up quickly, which attracts amphibians for reproduction. The maximal abundance of tadpoles due to a high reproduction rate was observed in partially drained ponds. However, a high larvae mortality rate was often observed there. Tadpole survival in flooded and empty ponds depends on factors that are not controlled by beavers, such as geomorphology and climate.
