Figure 5 Results of four variants of NC-clustering: NC-Ward (hierarchical, tree shown), NC-part.hclust (hierarchical), NC-part.kmeans (iterative vector-quantisation), NC-NMDS (non-metric scaling) ; 21 nest samples of Plagiolepis schmitzii (grey bars) and of 20 nest samples of Pl. atlantis (black bars). Outliers in NC-part.hclust are given by the white gap.
