Schematic representation of networks obtained for aquatic invertebrate communities after research of modularity with the algorithm of Louvain. The number inside the circle corresponds to the number of units composing each group and the width of edges is proportional to the strength of the similarity (i.e. the proximity) between the different groups. (A) Network obtained from the trait values resemblance matrix (referred as functional network). (B) Network obtained from the Bray-Curtis similarity matrix (referred as co-occurrence network).
