Aquatic invertebrates of the Ribnica and Lepenica Rivers: Composition of the community and water quality

Abstract

Results of investigating the community of aquatic invertebrates in the Ribnica and Lepenica Rivers (Kolubara River drainage area) are given in the present work. Forty-three taxa are recorded. In relation to other studied streams in Serbia, the investigated rivers are characterized by high diversity of macroinvertebrates. Cluster analysis indicates that the locality on the Lepenica stands apart from those on the Ribnica, which is a consequence of the difference of habitats found at them. Results of saprobiological analysis of the macrozoobenthos in the given rivers indicate that their waters belong to quality classes I and II.U radu se prikazuju rezultati istrazivanja vodenih beskicmenjaka reka Ribnice i Lepenice (sliv reke Kolubare). Zabelezeno je ukupno 43 taksona. Istrazivane reke odlikuju se visokim biodiverzitetom u poredjenju sa drugim ispitivanim tekucicama Srbije. Prema rezultatima cluster analize, lokalitet na Lepenici izdvaja se u odnosu na lokalitete na Ribnici, sto je posledica razlike u analiziranim stanistima. Konstatovana zajednica makrozoobentosa ukazuje na dobar kvalitet vode koji je na granici I i II klase boniteta.
