Sažetak
Sediment meiofauna and aquatic free-living nematodes were investigated at five littoral stations along the Drava River (11.0 – 77.0 stream km). Meiofauna abundance and diversity differ between investigation stations. In the sediment of station 5 (sandy sediment) only a few meiofaunal groups were found, with a high dominance of oligochaeta. The nematofauna of station 4 (sand-silt) differs from that recorded in the other stations investigated. In this station the lowest number of species was recorded, as well as the lowest diversity index (H’, d), and a high dominance of species (D%) belonging to the genus Rhabditis. Cluster analysis based on nematode relative abundance resulted in only station 4 being distinct. Biological data indicate the influence of the discharge of untreated effluent into the Drava River.
