Tendencies of Invasion of Alien Zoobenthic Species into the Black Sea. Russian Journal of Biological Invasions, 2020, Vol. 11, No. 2, pp. 164–171. © Pleiades Publishing, Ltd. N. N. Shalovenkov The Center for Ecological Studies e-mail: shaloven@rambler.ru |
The published data on alien species in zoobenthos of the Black Sea are generalized for the last hundred years of research. The list of alien species is prepared; 61 zoobenthic alien species are registered. The long-term variability of the invasions of alien zoobenthic species into the sea is analyzed. The intensification of invasion of the zoobenthic species into the Black Sea occurs during the period of climatic changes in the region. A statistically significant relationship is revealed between the interdecadal variability of the number of alien species and the deviations of the summer water temperature from the average interannual (100 years) one.
