Zoobenthos effect was categorized as five mechanisms; biopumping, nest-making, mixing and buring, excretion and particle redistribution. A highly significant correlation was obtained between nitrogen release rates and total biomass of Chironomus plumosus and Limnodrilus spp. The rates of release accelerated by zoobenthos were compared with some metabolic rates such as sedimentation, primary production, excretion, mineralization., Article, 信州大学理学部付属諏訪臨湖実験所報告 7: 113-120(1991)}, pages = {113--120}, title = {ZOOBENTHOS EFFECT AND THE ROLE OF ZOOBENTHOS IN THE NITROGEN METABOLISM IN A SHALLOW EUTROPHIC LAKE.}, volume = {7}, year = {1991} }
