ASSESSMENT OF THE ENVIRONMENTAL QUALITY AND ITS CHANGES USING INDICATORS OF ASYMMETRY IN VERTEBRATES

Aim: Environment quality estimation and its probable changes in the presence of anthropogenous influence on the Tatarstan republic natural reserved fond objects with fluctuating asymmetry method on different species of organisms was carried out. Methods: Gathering of scientific material was carried out at the 2012-2013 years period at the natural reserved fond objects territory – Tatarstan republic state natural complex wildlife areas. For ecosystems estimation the morphometric parameters of most ordinary species of fish (roach, golden crucian, bream) and amphibians (pool and marsh frog) was used. Morphometric measurements results of indicator organisms was statistically processed, fluctuating asymmetry parameter was calculated, according received results the state of ecosystems was estimated. Results: The state of some especially protected natural areas at the Tatarstan republic was estimated. Applicability of fluctuating asymmetry parameter for complex ecosystem estimation was proved. Received results can be used as a matter for ecological risk estimation methodic developing for Tatarstan republic territory. Conclusions: The investigated areas ecological status was estimated as “relatively normal”. Results analysis was shown the need of using different indicators for complex characteristic of environmental quality. Keywords: fluctuating asymmetry, ontogenesis stability, bioindication, ecological monitoring, wildlife area, especially protected natural territory, background area, ecological estimation, ecological risk.
