WebMay 7, 2024 · A Framework for Weighing the Relative Importance of Nestedness and Modularity Based on these factors that affect the characteristics of the orchid mycorrhizal network, we initially proposed a framework to weigh the relative importance of nestedness and modularity of the orchid mycorrhizal network ( Figure 2 ). WebIn spite of the relevance of nestedness and modularity for the stability and persistence of communities, the relationship between these structural patterns remains unknown (see Fig. 1).
