ESTIMATION OF THE ZONAL DISTRIBUTION OF SPECIES OF THE BOTTOM COMMUNITIES IN RIVERS OF THE MIDDLE AND LOWER VOLGA BASINS

Abstract

A comparative analysis of the variability of the specific structure of macrozoobenthos communities in small and medium rivers of the Middle and Lower Volga basin was made. A statistically significant influence of the natural-climatic zone where the waterway is located and a manifestation of the latitudinal gradient of biodiversity were shown. The list of indicator species with the use of various criteria of biotopic correspondence was composed for each identified geographical zone. The Indicator Value (IndVal) index was recognized as the most adequate one on the basis of our analysis, considering the zonal distribution of both the occurrence frequencies of a species and its abundance ratios. With the help of the APRIORI algorithm, associative rules containing combinations of species most often met together in hydrobiological tests have been formulated.
