Telling ecological networks apart by their structure: A computational challenge
Fig 1
PCA biplots of the two most explanatory principal components.
Each point indicates a single network, and the ellipses are drawn to contain approximately 68% of the points in each network type, i.e., one standard deviation if the points were to follow a bivariate normal distribution. PC1, principal component 1; PC2, principal component 2; PCA, principal component analysis; var., variation.
