Fig. 9. Effects of the level of matrix randomness on the standardized effect size of nestedness. Square, symmetric networks with rows and columns 30/30; Asy, asymmetric networks with rows and columns 5/55. Randomness, percentage of disordered cells deviates from fully nested matrix. Data contains a total of 4 850 matrices, with 4:100 (%) random-ness degree 97 levels of, 50 repetitions per level. NT, matrix temperature; NODF, nestedness metric based on overlap and decreasing fill.
