FINDINGS OF THE STUDY, BIOGEOGRAPHICAL ZONATION OF COASTAL AND ISLAND ECOSYSTEMS OF THE CASPIAN SEA

Abstract

Aim. The aim is to carry out the typification of faunas and biogeographical zonation of coastal and island ecosystems of the Caspian Sea. Methods. Revision of fauna of separate groups of invertebrate animals and vegetation cover of coastal and island ecosystems of the Caspian Sea was performed according to the modern taxonomy, unified collection technique and cameral processing of collected field material. Results. For the first time, solution for the actual biogeographical problem is found; the structure, composition and main regularities of the geographical distribution of several groups of invertebrate animals and plants of coastal and island ecosystems of the Caspian Sea have been identified. Conclusion. The data obtained make it possible to better assess the state of ecosystems and determine the impact on social and socio-geomorphological systems, largely determining the structure and boundaries of the latter, thereby predicting the consequences of anthropogenic activity for the nature and establishing the spatial limits of this impact.
