M.Öpik and M.Moora published a commentary paper about two recent studies applying bipartite network analysis to describe arbuscular mycorrhizal (AM) plant-fungal community patterns. Network analysis investigates interactions of organisms at the community level – here among community of AM plants and community of AM fungi colonising their roots. The commentary highlights importance of sampling strategy, addresses different uses of term “specificity” (of interaction, of habitat, etc.), calls for describing more autecological traits of AMF and, of course, of sequencing more Glomeromycota species.
