Sergeyeva N. Zonal distribution of meiobenthos and its most important component - free lifing nematodes in Black sea

Blask sea meiobenthos and its most important representative - free living nematodes , the main objective - formation of a net scientific conception on the sonal distribution of live in Black sea. The laws of benthos vertical distribution on have been described on the base of the studies of taxonomical composition and quantitative developwent of the botton fauna in the oxidative, intermediate and restoring sones of Black sea. The character jf shorf - and long dynamics in the specific composition of nematode fauna, its quantitative andtrophic characteristics in the community of cystoseira and phyllofora meioepiphyton has been revealed. Meioepiphyton was sampled with the help of light diving equipment, mriobenthos of soft botton - with dredges and cassette samplers. Meioepiphyton and soft botton benthos in the aerobic sone were processed by common methods in meiobenthology, and for studies of anaerobic sone botton sediments - by an original method, a new scientific conception of life distribution in Black sea, which makes grounds for the next stage in hydrobiological srudies of the given water resewoir has been worked out. New conception is a theoretical prereguisite for ecological expertise in wing natural resources of the anaerobic sone. The unified indices for evaluation of the coastal sone state were recommended. The results were used in realisation of a number of the budget and ordered themes. Hudrobiology, ecology, monitoring of the state of marine environment.
