Alekhinа G.P., Misetov I.A. INFLUENCE OF ANTHROPOGENIC LOAD ON SOME POPULATION-SPECIFIC CHARACTERISTICS OF THE BIVALVE UNIO PICTORUMLarge bivalves, benthic invertebrates and higher algae are an important component of self-purification of water bodies, so that changes in the structure of the population, of course, affect the ability of the pond to cleanse itself. The object of the study were freshwater bivalves class Bivalvia, members of the family Unionidae selected from the points differ in the intensity of human impact. Processing of samples was performed by standard techniques, species of mollusks and microorganisms belonging determined using standard determinants. Earlier studies have allowed to define a wide range of individual and population parameters Unio pictorum, analyze the chemical composition of water in the test points and hold the selection and identification of microflora shellfish. In order to identify the most important relationships and dependencies of ecological status of water bodies and population-species characteristics of the bivalve Unio pictorum correlation analysis was performed. The result showed that the factors influencing each mollusc and factors affecting the whole population are not isolated from each other. These pressures at the reservoir primarily affects the individual characteristics mollusk (weight, length, age) and then through the breach microflora clam manifested in the reduction of biomass, population density, i. e. affects the population Unio pictorum in general, all this leads to reduce reservoir capacity for self-purification and water ecosystem destabilization of the middle reaches of the Ural River and its tributaries.Key words: shellfish, the population of microorganisms, water pollution.
