Nakonechnyi I. Structurally functional the organization parasitecenosis communities of southwest Black Sea Coast.

So it is stated that structure and functional activities of parasitecenosis answer to the conditions environment and level of biodiversity of local ecosystems. Composition, function and dynamics of activity of communities are always directed on realization of fundamental property of ecosystems - abilities to self-restoratir and energy self-control. In the conditions of intensive agricultural transformation of steppes, region ecosystems have lost a primary biodiversity that has naturally led to sharp infringements faunistic, and accordingly connected with them parasitecenotic communities. Penetration on territory of zone steppes autochthonic biota, replacement of wild hoofed animals by domestic one acclimatization different plant species and animals, promoted establishment new biocenosis formations. Against the general changes of mammal - the main owners and carriers of infectious parasites, redistribution structure population type-statsialis specificity natural centers' zoonosis takes place that defines activity and seasonal prevalence epidemic danger level of separate districts. Representations about uniform ecologic-social essence epizootic are thus considerably expanded and epidemic displays of natural infections, conditions and ways of secondary migration of their activators to the person are detailed. Scientifically well-founded directions and ways of the further researches in the field of nature protection ecology and biosafety of an environment are put. Theoretical disclosing of the basic regularities of deduction of functional stability of ecosystems allows to offer original, principles of construction of the ecologic-provided technologies of the wildlife management, considering value of infectious regulation. Conscious use of their activity is one of the optimal means of struggle against field wreckers, and also promotes preservation of partial self-control of ecosystems and their biodiversity. Key words: ecology populations, system approach, biodiversity, structural and functional organization of ecosystems, the parazitocenotecenosis community, natural and endemic infection, human zoonotic infection, field types of rodents, biosafety environment.
