Interlinked species. Venn diagram illustrating the number of species in PIDA that hold multiple ‘roles’ and are present in more than one interaction network/type; i.e., either present in two distinct networks (e.g., registered as ‘Prey’ in the predator–prey network, and also as ‘Symbiont’ in the symbiont–host network) or on both sides of the same network (e.g., registered as both ‘Predator’ and ‘Prey’ in the predator–prey network). Letters A–L refers to the panels in Table 2, where the taxonomy of the different overlapping species and their roles are presented. ‘Parasites’ were only found to overlap with ‘Host of parasites’, representing two cases of hyperparasitism (i.e., parasite species parasitizing other parasite species). The unresolved interactions are not included in this analysis since their functional roles are unknown. Only taxa with full species name determined were included to avoid overestimating overlapping species (e.g., Amoebophrya NA and similar were excluded)
