ВInfluence of long-term dynamics of weather conditions on population of waterbirds of arenous areas of the Black Sea Biosphere Reserve in a breeding period.

Y. A. Moskalenko

The communication is dedicated to the analysis of the long-term fluctuations of weather conditions on population of waterbirds. The observations were conducted on arenous areas of the Black Sea Biosphere Reserve in breeding periods of 2001-2009. The research has shown that hydrological conditions of closed lakes of arenous areas are dependent on fluctuations of humidification regime. Byturn, it was revealed that some bird species are linked with watering dynamics of closed lakes. Thus, appearance on breeding on arenous areas of the reserve of such species as the Little Ringed Plover (Charadrius dubius) and Kentish Plover (Ch. alexandrinus), Black-winged Stilt (Himantopus himantopus) and Avocet (Recurvirostra avosetta) in a dry period is conditioned by appearance of relevant breeding biotopes, namely open salt marshes along the periphery of drying lakes. Nevertheless, the obtained data testify that the long-term fluctuations of weather conditions produce an effect on the community of waterbirds more by changes in watering of wetlands in the region in whole than by changes in hydrological conditions of lakes directly in arenous areas.
