Ecosystem respiration as a function of sediment organic matter quality and net ecosystem production (i.e. autochthonous organic matter).

The coefficient indicates the directionality of the relationship while r2 indicates the goodness of fit. Significant p values are in bold. NEP and respiration were analyzed as mmol C m−2 d−1. *Partial r2 was calculated by dividing the type III SS by the corrected total SS.
