GEOECOLOGICAL ANALYSIS OF THE NW BLACK SEA SHELF BASED ON THE STUDY OF OSTRACODS
When undertaking geoecological monitoring, one of the important aspects is the choice of a sensitive bioindicator system, which responds to the conditions of accumulation of toxic substances in bottom sediments (Kravchuk and Kravchuk 2000). Biological components comprising the ecological biotopes of the shelf region are controlled by the physico-chemical parameters and the concentration of a substance within sediments. The assessment of the situation and the general knowledge of the active processes can be obtained by investigating the changes in species content of various groups of living organisms. The pollution of marine environments by organic byproducts causes noticeable influence on the ostracod communities (Kravtsov et al. 2007).
