Abstract
Network metric for host-parasites communities, based on adjacency matrices, divided into all parasites (ALL), facultative parasites only (FAC). and obligatory parasites only (OPC). <strong>network :</strong> unique network identifier (community number, parasite type, host type)<br><strong>connectance :</strong> number of infections / community richness<br><strong>size :</strong> total richness of the community (hosts + parasites)<br><strong>parasites :</strong> number of parasites<br><strong>hosts :</strong> number of hosts<br><strong>nestedness :</strong> NODF measure of nestedness<br><strong>average_host_range :</strong> mean host range, measured using the RR metric - values closer to 0 indicate generality<br><strong>number_modules :</strong> number of community modules found<br><strong>modularity :</strong> Qbip modularity, optimized using the LP-BRIM method<br><strong>null_nestedness :</strong> average NODF of 1000 null replicates<br><strong>nestedness_pvalue</strong> : significancy of the deviation between null and empirical nestedness values<br><strong>null_modularity :</strong> average Qbip of 1000 null replicates<br><strong>modularity_pvalue :</strong> significancy of the deviation between null and empirical nestedness values<br><strong>null_model :</strong> type of null model, either I or II<br><strong>parasite_type :</strong> type of parasites considered (all, facultative, or obligatory)
