Scatter plot of the discriminant analysis of principal components using clusters identified de novo. Nine principal components (PCs) were retained to avoid overfitting, resulting in a mean a-score of 0.71. Ellipses indicate the 95% interval of assignment. Insets depict the principal component analysis (PCA) and discriminant analysis (DA) eigenvalues. Highlighted bars in insets show the number of PCs retained and the discriminant functions visualised, respectively
