Climate changes in the basin of the Lower Volga and their influence on the ecosystem.

In the basin of the Lower Volga, the main trends of climate change and their impact on the dynamics of ecosystems are identified. The results were obtained by analysis of longitudinal meteorological characteristics (average, maximum, and minimum air temperature and total seasonal and year precipitation) and the establishment of expected changes in the land ecosystems and landscapes. The basic directions of the aggregate impact of changes of the humid-temperature regime in the basin of the Lower Volga are identified, and the general directions of the dynamics of terrestrial ecosystems in this regard are stated.
