图7. 矩阵随机化程度对嵌套性度量指标的影响。Square, 对称网络, 行列数30/30; Asy, 非对称网络, 行列数5/55。随机化程度, 网络中无序单元格的数量/单元格总数量。随机程度包含4:100 (%)共计97水平, 每水平50个重复, 共计4 850矩阵。
Fig. 7. Effects of the level of matrix randomness on nestedness metrics. 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 (%) randomness degree 97 levels of, 50 repetitions per level.
