Variations of the water regime of bogs of northern and northwestern Russia under influence of climatic factors.

A considerable variation of hydrological regime of oligotrophic bogs of northern and northwestern Russia takes place during all phases of hydrological year under influence of climatic changes of recent decades. The mechanism and factors of climate changes influencing the regime of bog water level and the runoff from bog massifs are revealed. It is demonstrated that the change in the hydrological regime influences the stability of ecosystems of oligotrophic bog massifs.
