Rusev I. North-West coast of the Black sea ecosystems as a basis for the formation of dangerous faunistic complexes and their structural - functional organization

Objects are faunistic complexes of birds, mammalian and bloodsucking arthopods, as components of ecosystems of natural foci of especially dangerous infections, natural foci of causative agents of infections. The aim is to study the structural and functional organization, direction and mechanisms of transformation of dangerous faunistic complexes natural foci of expecially dangerous infection in the Northwest Black Sea region under the influence of natural and anthropogenic factors. Methods - field, cameral, mathematical. In the work is revealed specificity of the formation dangerous faunistic complexes and revitalization of the natural foci of plague, showing features of the consortium relations between fellow members of parasitic communities, provides advanced understanding of relic natural plague foci and dangerous faunistic groups of recent natural foci. Proven a possible increase the risk of human infection with arbovirus against the backdrop of climate change, by lengthening the recreational period for the population and the lengthening of the period of exposure to natural foci of infections; expansion of place of breeding, growth the number and the number of species of mosquitoes; increased the numbers and the increased number of bird species the out of nesting period. The results can serve as a theoretical basis for the improvement of animals and environmental-epizootological monitoring and evaluation of biological risks on tularemia, plague, arbovirus infections, ornithosis, highly pathogenic strains of influenza H5N1 and other especially dangerous infections, where key role played a faunistic complex of different systematic groups.
