“Double carousel” of the succession process in a regional ecosystem

Abstract

Southern taiga forests of Western Siberia are used as an example to demonstrate the mechanism of “flickering“ in the mosaic pattern of plant cover, which reflects natural, regular cycles of progressive succession starting at different times in each contour of the geobotanical map. The primary plant formation with time depletes the resources of its ecotope, transferring biophilic elements from the soil to the phytomass, fruits, and seeds. Its immunity is gradually impaired, making the formation vulnerable to the attacks of pests, diseases, and fires. Its death is followed by a cycle of progressive succession, which renews the ecotope resources and allows the primary formation to move within its range, despite that the trees are fixed and immobile, which provides for its indefinitely long existence.
