Abstract
Benthic community respiration rates of profundal sediments of Fuschlsee (37.6 mg · O2 · m−2 · h−1 — eutrophic), Mondsee (40.19 mg · O2 · m−2 · h−1 — eutrophic) and Attersee (11.5 mg · O2 · m−2 · h−1 — oligo-mesotrophic) were measuredin situ, and in cores. By exposing the sediments to different oxygen levels in the laboratory it was found that benthic community metabolism reduced with decreasing oxygen concentrations. The slope of the regression lines, relating oxygen uptake rates to oxygen concentrations, differed significantly for the different sites investigated. These results were closely related to the trophic conditions of the lakes.
