THE STRUCTURE OF A BENTHIC COMMUNITY IN THE FORESTED RIVER ECOSYSTEMS
At the beginning of a winter season, river ecosystems of the broad leaved forest zones accumulate huge amounts of a leaf litter. During this period, the trophic structure of the zoobenthos community, with a predominance in the large particulate shredders (Gammarus, larvae Pteronarcys), is formed as a launch for the next growth season. While in the recent years in some parts of the East Asia late-autumn floods increasingly began to occur that are likely to be associated with the global climate change. As a result, the accumulated leaf litter is being removed from the river ecosystem before the freeze-up. Under such conditions, the other trophic structure of the benthic community formed, in which, the role of the large particulate shredders and collectors (larvae Baetis) drastically reduced, while the share of the periphyton grazers (larvae Glossosoma, some Heptageniidae) and predators (larvae Kamimuria) is increased.
