T1 Zoobenthos and Zooperiphyton of the Irtysh river JF Hydrobiological Journal JO HYD YR 2000 FD 2000-02-01 VO 36 IS 1 OP 17 AB The structure of zoobenthic communities occurring on different bottom sediments and changes in the communities of zooperiphyton occurring at different depths of the Irtysh river have been studied. The role of zoobenthic and zooperiphytic organisms in drift has been shown. Peculiarities of the spatial distribution and growth of the dominant species Hydropsyche ornatula (Trichoptera) in different biotopes of the river have been investigated.
