Figure 5

Relationship between total number of species and network metrics for (a, b) number of interaction links, (c, d) connectance, and (e, f) nestedness. Left (a, c, e) and right (b, d, f) panels are based on data including exotic species and excluding associations with exotics, respectively. Code numbers next to the circles indicate study site codes, which are provided in Table 1. Lines represent linear regressions: (a) number of interaction links (I), log(I) = −0.9601 + 1.2570*log(S), r2 = 0.96, F1,5 = 118.52, p = 0.0001; (b) log(I) = −1.0341 + 1.2774*log(S), r2 = 0.99, F1,5 = 334.95, p < 0.0001; (d) arcsin C = 1.0479 – 0.1894*log(S), r2 = 0.94, F1,5 = 74.16, p = 0.0003.
