Macroinvertebrates-invaders in the Kiliya delta of the Danube River.

Abstract

On the whole, 17 species of macroinvertebrates of alien faunistic complexes subdivided into the denizen (11) and occasional (6) species-invaders were found in the Kiliya delta of the Danube River during 100 years of investigations. It has been found that in recent decades the number of species-invaders increased by a factor of 2.4 primarily at the expense of the development of representatives of the Sino-Indian faunistic complex, which can be considered as the consequence of climatic changes in the region. The first species-invaders were registered in the front part of the delta - in the zone with a high dynamics of hydrochemical, hydrological, and hydromorphological processes resulting in the formation of free ecological niches.
