Interactions network based on relative abundances for recovered strongylid species. A network, drawn using a force-directed algorithm from the matrix of interactions estimated by pairwise Poisson regression on species counts after accounting for environmental effects. To avoid spurious positive associations due to low counts, the analysis was restricted to the only species totalling 200 worms overall. Nodes act as repelling objects that are organized to minimize forces in the network. Each node represents a species and is coloured according to the genus it belongs to. Connected nodes entertain significant association after Bonferroni correction for multiple testing (P < 5 × 10-4). Edges are coloured to reflect the correlation sign (red if positive, green if negative) and their widths mirror the association intensity (the thicker, the bigger absolute effect)
