Illustrations of A - negative asymmetry, and B – positive asymmetry at predator–prey nodes. In these hypothetical examples, the perspective is that of a parasite whose larval stage is in the rabbit intermediate host, and adult stage in the fox definitive host. In this scenario, the other hosts are not parasitized. C. Summary of mean asymmetry values for all nodes (open circles) and parasitized nodes (closed circles) from 5 published webs; Pin- Pinelands NJ, Car – Carpenteria marsh CA; CaK- Carpenteria modified web CA; Yth -Ythan estuary, Scotland; Tuck –Tuckerton salt marsh, NJ by Rossiter and Sukhdeo 2011[21].
