Sediment cores conta~ning different dens~t ies of Tubifex tublfex ranging from 0 to 70000 ind m-' were incubated in the laboratory Rates of O2 and NO, uptake NH,' production n~tr~fication and denitnfication were determined from sediment-water fluxes Pore water NH,+was measured at the end of the expenment At natural densities -50000 ind m ', there were increased rates of O2 consumption (x2), denitnfication of water phase NO; (x3) and NH,' efflux (x26) Nitrification was stimulated at low worm… CONTINUE READING
