Graphical presentation of multivariate unsupervised data analysis: (A) Dendrogram obtained from hierarchically clustering columns of RA matrix with average linkage and Euclidean distance. The red broken line cuts the dendrogram at a height of 8. This cut results in three distinct clusters, shown in different colours. (B) Scores plot calculated by submitting observations in RA matrix to multiclass Principal Component Analysis (PCA). (Alga) = Galdieria sulphuraria pure cultures; (Fungus) = Penicillium citrinum pure cultures; (Alga + Fungus) = Penicillium citrinum and Galdieria sulphuraria co-cultures. EV = Explained variance.
