Klymenko O. Ecological adaptation of sand lizard in the conditions of technogenic pollution of biogeocoenoses of the steppe Dnieper region.

The object is ecological, population biochemical and histological indexes of sand lizard, which are characterize the certain changes in populations from differently polluted biogeocoenoses. The aim is to determine the basic ecological, biochemical and histological indexes that can characterize the adaptation reactions of sand lizard on a population and organism levels on conditions of technogenic transformation of biogeocoenoses of the steppe Dnieper region. The methods are the field, laboratory: morphophysiological, biochemical, histological. Ecological parameters of the sand lizard populations from differently polluted biogeocoenoses are investigated. The populations' density, age groups and sexual structure of populations, morphophysiological indices from biogeocoenoses of different technogenic load were determined. Biochemical indicators are studied: hepatic markers, antioxidative protective system, cytoskeletal molecular marker in the brain and histological changes in liver, kidneys and brain of the sand lizards from the biogeocoenoses of different technogenic load. Studied parameters (population structure, glial fibrillar acid protein (GFAP), superoxide dismutase, catalase, lipid peroxidation, aspartate aminotransferase, alanine aminotransferase, histological changes), are proposed for the research of types of populations and influence of complex industrial pollution on the lizards population. GFAP is informative biomarker of the pollution influence on the lizards. Application spheres are bioindication, biomonitoring, biotesting.
