Abstract

Aim . Studied the fauna of the soil mites of coastal and island ecosystems of the North-Western part of the Caspian sea (Bryansk spit, Strategiczne, Islands seal, Chechen and Nordby). Found 49 species and 39 genera and subgenera, and 24 families. Species composition of oribatidmite of theNorth-western part of the Caspian Sea remains not completely studied. The aim of the work was to study the species composition of oribatidmite ecosystems of the North-Western part of the Caspian Sea. Location. Coastal ecosystems north-western part of the Caspian Sea.Methods. The selection of soil samples in different habitats and MicroStation is the basis for studying the biodiversity and abundance of soil microarthropod. To extract small soil organisms method was used electoral forcing, which is based on the use of negative phototaxis soil organisms. When the definition of oribatid mites used the microscope MBI-6, Olympus CH-20.Results. As a result of studies 41 species of oribatidmites, 9 of which – new forthe fauna of the Caucasus, 17 species – new for the fauna of Dagestan, one species – new to science were identified. There sults can be used to compile regionallists, inventories and will be included in the list of directories oribatidmite of Caucasus.Main conclusions. There sults showed that for both are as of studies - 9 species, exclusively in coastal ecosystems of Bryansks pit 24 species, found only in ecosystems Staroterechnogo 9 species are common.
