Summary

Description
English: Generalised food web for sponge reefs

Taxa were considered if they were present on two-thirds of the reefs included in this study. Two taxa, Ceramaster patagonicus and dorid nudibranchs, were also included due to previous work indicating their strong association with live reef habitat (Chu and Leys, 2010; Dunham et al., 2018). The size of each node corresponds to its relative importance in the food web. SR represents small rockfish. Several nodes in the generalized food web represent tropho-species. When this is the case these tropho-species have been given descriptive names (e.g., Shrimps). Large and small rockfish represent tropho-species and were given names based on the relative adult size of the species in the tropho-species group.
