Towards a Change in the State of the Batrachofauna in the Oka Nature Reserve
摘要
Abstract
This article examines trends in the abundance of amphibians in the Oka Nature Reserve under the influence of climatic and biotic factors. A decline in the population of amphibians has been observed due to changes in the hydrological regime of the Oka River, affecting the water regime of spawning habitats; the introduction of the Amur sleeper Perccottus glenii into these habitats; and temperature and hydrological conditions during the breeding period.
