Mykitchak T. The structure organization and protection zoomicrocoenoses in water ecosystems of Chornohora (the Ukrainian Carpathians).

The objects are Cladocera's and Copepoda's zoomicrocoenoses in reservoirs of Chornohora. The aim is to study of structural organization of zoomicrocoenoses - components of gidrobiogeocoenoses in reservoirs of Chornohora. Methods are - biogeocoenotical, ecological-faunistical, hydrobiological and statistical. The thesis contains the analysis of structure organization of zooplankton communities (Cladocera, Copepoda) in reservoirs of Chornohora (the Ukrainian Carpathians) in view of biotopical diversity features, hydrochemical regime and anthropogenic pressure. The attention is given to sex, age, dimensional and weight population structures, and to number, zone and vertical stratification, biotopical distribution, interspecific connections as well. The rules of dynamic changes of population parameters of main and usual species is specified. The phytoliking, littoral, pelagic, astatic ecological complexes of zooplankton's species of high-mountain hydrocoenoses are allocated. The reservoirs classification for zoomicrocoenoses and level of antopopressure is carried out. The basic conditions for protection of rare hydrocoenoses of Chornohora are marked. The role of biotopical heterogeneities as positive factor of formation of a hydrobiodiversity is pointed out. Spheres of use are the fish industries, protection measures, training courses.
