Network link prediction
The plug-and-play algorithm performed solidly (mean AUROC = 0.72,
full model AUROC = 0.85) despite the missing data (Fig. 5a) and
outperformed the Poisson N-mixture model (mean AUROC =
0.59). According to the former, a substantial amount of species
interactions likely remains undetected (Fig. 5b; Appendix S7). All input
parameters improved performance of the plug-and-play algorithm
(Fig. 5c). However, the ecosystem, host and parasite phylogenies, and
trophic level parameters were significantly more important than
morphological parameters including the host length and attachment and
reproductive organ measurements.
