Fig. 5From: Signatures of ecological processes in microbial community time seriesInferred interactions in stool data sets. The inferred interaction matrices are represented as directed networks, where nodes are OTUs labeled with their genus or higher-level taxon name and directed edges represent non-zero entries in the inferred interaction matrix. Directed edges with positive signs are colored in green, those with negative in red. Orphan nodes are not shown. a In the network inferred for the stool time series of individual A, a negative hub is formed by a Faecalibacterium OTU. b In the network of individual B, the same Faecalibacterium OTU (OTU_165924) also forms a negative hub. Interaction matrices inferred with LIMITS were visualized with igraph [53]Back to article page
