STABILITY OF MACROZOOBENTIC COMMUNITIES IN RIVER MAŁA INA, A LEFT-BANK TRIBUTARY OF RIVER INA (NW POLAND)

Abstract

The study results presented include an analysis of the biological material collected in May 2007 and 2012 from the Mała Ina river located in the Ina River basin. These served as the basis for determining the taxonomic structure of macrobenthos. The river studied varied with regard to the qualitative and quantitative structures of individual taxa, and the biodiversity in the streams was very low. Despite a significant difference in the number of individuals making up the benthos in the analyzed periods, in terms of quality, this group consisted of almost the same in terms of taxonomic organisms.
