A food web is a diagrammatic representation of energy and material fluxes among organisms via trophic interactions (Cohenet al., 1993a). Connectance webs have been a central organizing concept in ecology since the late 1920s (Elton, 1927), but they are restricted to simple presence/absence dat...
With this definition a value ofrclose to 1 indicates that the two networks have very similar TSPs and thus patterns of over- and under-represented triads, a value close to 0 indicates no similarity, and a value close to −1 indicates anti-similarity—i.e. triads over-represented in one...
