Slobodian Е. Ecological role of populations Trichius fasciatus Linnaeus, 1758 in meadow ecosystems Gorgan.

The dissertation is devoted of studying polymorphism, structure and dynamics populations T. fasciatus. It is analysed sexual structure of populations T. fasciatus. It confirms the theory about the genetic nature of the investigated cases of polymorphism. The high-altitude gradient of distribution of various hair driers T. fasciatus is investigated. Presence of high correlation of frequency of occurrence of various hair driers, their not casual combination. And also is described consortional communications T. fasciatus with grassy plants. Found that populations of species T. fasciatus is polymorphic for a number of morphological features, exactly: are 35 basic types of fans that the various morphological characteristics, a combination which creates a high individual variability of investigated specimens. Investigated the role of environmental, trophic and consortiums relationships Trichius fasciatus Linnaeus, 1758 (Scarabeidae, Coleoptera, Insecta) in prairie ecosystems Gorgan. Shown particular trophic specialization adults T. fasciatus - frequency of visits to different types of flowering plants, especially the phenology of this species as a member of a consortiums.
