FIG. C1. Change in DON and DOC in laboratory microcosms. Mean (± 1 SE, n = 4) production (above 0 line) and consumption (below 0 line) of (A) DON, and (B) DOC during sediment incubation experiments. Asterisks indicate significant (P < 0.05) differences between live and dead treatments as determined by paired t tests.
