Fig. 6: Modules and niches of AD0.5, AOM and CK group.
From: Marine toxin domoic acid alters nitrogen cycling in sediments
Colors of nodes indicate different major phylum and nitrogen cycling genes; pie charts represent the composition of N (nitrogen) cycling niches. Inside each module, a red link suggests positive covariation between two individual nodes, whereas a blue link reflects negative covariation. Nitrogen cycling: ammoniation, nitrification, denitrification, Anammox, nitrogen fixation, DNRA (dissimilatory nitrate reduction to ammonium). AD0.5 = modified with algal organic matter and 0.5 mg/l domoic acid, AOM = modified with algal organic matter only, CK = without any modification.
