Abstract

The biological reserve ecosystem, developing in the conditions of global natural loading, should not be broken. It is the basic postulate of wildlife in our proposed concept, as a biological reserve reflects the margin of stability of the ecosystem, its tolerance to minimality-limiting factor (Liebig's Law of the minimum).

Functioning and sustainability of ecosystems are determined by the variety of species and their life-strategies. The potentials of sustainability and capacity of ecosystems in relation to the anthropogenic factor, are due to the adaptive response of the species to man- made stress. The potential of sustainability, calculated for radiation exposure, as the ratio of the actual dose to the maximum permissible one, reflects the evolutionary stability of the existing ecosystems to the external annual dose of radiation, i.e., the natural background.

Sustainability is the result of the combination and integration of different ways of protection. In this case, the population of species protects itself by the peculiarities of its structure (demographic structure variability, modification variability); the cenosis (community) protects itself by the variability of vertical and horizontal heterogeneity; the topological system makes it with the help of changeability direction and speed of the successional dynamics, etc. It is shown that this mechanism is bio-barrier protection of the biosphere, which is a biobarrier protection concept. The examples of biota protection at different levels are displayed on the maps.

Keywords

stability as a result of the combination of methods of protection, bio-barrier mechanism of protection of the biosphere, variability as protection response.
