WebUnlike the objectives of analysis found in the studies of [9] [11] and [12], when addressing ecosystems and the objectives of Hausmann and [3] and [4], the present study sought to identify and map patterns of nestedness and modularity to better understand the structures underlying processes of organizational knowledge creation and diffusion in the network … WebThe anti-nestedness property in our mangrove–phyllosphere fungal networks may be affected by a low number of host plants (six true mangrove species and five mangrove associates) but modularity seems to be not. Further, high nestedness and modularity may be associated with increasing connectance (Fortuna et al., 2010; Põlme et al., 2024).
