- Аннотация: The trends we describe could be considered as common responses of collembolan communities to stress-factors. Some of these can be applied to communities of many other groups of organisms, as shown in Connell’s hypothesis of “intermediate disturbance”. The phenomenon of reduced of stability and specialized species under stress-factors can be found in living systems ranging from cells to ecosystems. Only a small part of biocenoses – taxocenosis (namely, species populations of one taxonomic group in a biocenosis) was considered here. Collembola taxocenoses consist of organisms of the same trophic level and are probably based mainly on competitive interrelations among species. The similarity of processes of community transformation under impact of different stress-factors could be explained if taxocenosis is treated as a phenomena having properties of system organization. The general peculiarities of disintegration of complex systems provide the foundation for these processes. Description of common responses of communities to stress-factors allow to order a vast factual material and to use it in bioindication.
