Fig. 1: Changes of inorganic nitrogen concentrations and potential nitrogen transformation rates in the systerm.
From: Marine toxin domoic acid alters nitrogen cycling in sediments
The variations of ammonium, nitrate, and nitrite concentrations in the overlying water (a) (n = 3 biological replicates). The potential rates of nitrification, DNRA (dissimilating nitrate reduction to ammonium), denitrification and Anammox in sediments under different treatments (b) (n = 3 biological replicates). CK = without any modification, AOM = modified with algal organic matter only, AD0.1 = modified with algal organic matter and 0.1 mg/l domoic acid, AD0.5 = modified with algal organic matter and 0.5 mg/l domoic acid, AD1.0 = modified with algal organic matter and 1.0 mg/l domoic acid. Error bars represent mean ± standard deviation.
