Summary

Description
English: Salt marsh food web

The structure of the food web at Secaucus High School Marsh. The marsh food web (a) without grouping, and (b) with species sorted according to their group affinity. The lines connect a consumer with a consumed species; the nodes represent species identified in Table S1 . The grouping configuration is determined by Allesina and Pascual (2009), assessed using AIC, a configuration containing 15 groups was the best fit of the data. The grouping algorithm, seeks to partition the species into groups that make the density of connections within each sub-matrix maximal/minimal.
