Fig. 1From: Vallisneria spiralis L. adaptive capacity improves pore water chemistry and increases potential nitrification in organic polluted sedimentsPore water concentrations of dissolved ammonium (NH4+, A) and soluble reactive phosphorus (SRP, B), and potential rates of denitrification (PD, C) and nitrification (PN, D). Concentrations are expressed in μM whereas rates are expressed in nmol of N produced per day (d) per gram (g) of wet sediment. Bars represent standard error (se).
