Divergence of biogeocenoses within pine forest types

详细

The paper is devoted to the analysis and generalization of the results of stationary studies on differentiation of factors of the epi-soil environment, natural forest regeneration, and formation of secondary dendrocenoses on burns and clean cuts in two pine forest types most prevalent in the pre-forest–steppe subzone of Western Siberia (Pripyshmiskian pine forests). It is shown that the same primary forest type (or even biogeocenosis) in burns, on the one hand, and in clean cuts, on the other hand, is replaced by two types of biogeocenoses that are alternative to each other in terms of structure and functions and represent qualitatively different, diverging ecodynamic series of natural regeneration and development of the primary, autochthonous forest type.
