Release of CO2 from sediment microcosms. Intact sediment cores were either kept untreated (green) or defaunated on day 6 by deoxygenation (N2 purging). Defaunated cores were either kept without animals (black) or added Nereis diversicolor at a density of 1390 m-2 on day 13 (after Hansen and Kristensen[46]).
