MATHEMATICAL MODEL OF PECULIARITIES OF SIMILARITY, DIFFERENCES AND GEOGRAPHICAL RELATIONS OF SCOOPS FAUNA OF COASTAL AND ISLAND ECOSYSTEMS OF THE CASPIAN SEA

Aim. The study of the material collected, as well as the construction of mathematical models of specific sadstia and differences of the geographical relations of the fauna scoop coastal and island ecosystems of the North-West.Location. Coastal and island ecosystems.Methods. Traditional methods of collection (light traps, method ofhand collection from the screen) and also collections of the material gathered, arranged by modern systematics are used.Results. Investigations of a lethors who studied scoops during 40 years are generalized but island ecosystems are considered for the first time. Fauna of the Caspian coast and island ecosystems is represented by 902 species. Mathematical model of peculiarities of similarity was constructed on the basis of the data obtained, and it helped to expose geographical relations of scoops fauna of coastal and island ecosystems of the Caspian Sea.Main conclusions. The results obtained together with other insects will be the bans for the composition of fauna cadastre, and will also help to realize the age and origin of islands.
