Gromenko V. Flora-faunistic description of biogeocenoses of Crimean Prisivashshya: composition, structure, variety.

Object - biogeocenoses of Crimean Prisivashshya. The purpose of the work is picking up of flora-faunistic biogeocenoses complexes Crimean Prisivashshya and characterization of their composition, structure and diversity. Methods used are field surveys and modelling. Within the limits of landscape ecosystem of Prisivashshya 5 types of biogeocenoses are isolated: salt marsh, steppe, meadow, water bog and weed field. Taxonomical and ecobiomorphological structure of floristic and faunistic complexes of every biogeocenose was found. Within its limits 278 species of flora and 1198 species of fauna were found. It is shown that animals taking part in forming of functional structure of biogeocenoses belong to five trophic groups. The vertical (tiers, biogeohorizons) and horizontal (parceles) limits of biogeocenoses are also isolated. It is found that they change in time and depend on the seasonal dynamics of phenological phases of plants and animals. It is found that they change in time and depend on the seasonal dynamics of phenological phases of plants and animals. Scope - the educational process, establishment of ecological corridors, and agriculture.
