SMALL MAMMALS OF THE TAMAN PENINSULA
Description
In the present study, fauna of small mammals of the Taman Peninsula is analyzed. It is shown that the complex of rodents and insectivores inhabiting the study area differs considerably from the adjacent continental areas and is an isolate. Structure of its fauna and population resembles that of the steppe parts of Crimea and, at the same time, North-West NearCaspian areas. Analyses of variation of the D-loop regions of mtDNA in yellow-bellied mouse Sylvaemus witherbyi, as well as certain peculiarities of the species diversity, show the priority of faunal and genetic connections of the Taman Peninsula’s mammal fauna with the North-West Near-Caspian one

Description
The article presents monitoring of the course and the beginning of new invasions due to the intensification of these processes in the basin of the Azov Sea of; investigation of the influence of the alien species upon the acceptor ecosystem. Methods. The material was collected at the monitoring transect in the Don River delta and in the surveys of the r/v “Professor Panov” in the Taganrog Bay, Sea of Azov. Standard hydrobiological methods of the data collection were used. Results. Penetration of three polychaete species was recorded; course of invasion of two of them was traced. Impact upon the acceptor ecosystem was researched. Preliminary species identifications using morphological characters were carried out; sources and the ways of the invasions are suggested. Conclusions. Estuary zone of the Sea of Azov (the Taganrog Bay) has a high invasion capacity. Of the three species penetrated into the Sea of Azov basin in 2013-2015, one (Aracia sp.) naturalized successfully, though didn’t affect much the ecosystem. On the contrary, polychaetes of the genus Marenzelleria are increasing rapidly their area; in two years, they became dominant along the considerable part of the water body. The invasion of Streblospio sp. is at its very beginning at the time
