Figure 8a - Dendrograms showing the relationships between Meristograms for the Echinorhynchus taxa. A principal component analysis was applied to the Meristogram data and the dendrograms were created from hierarchical clustering of the scores for principal components one and two. Hierarchical clustering was performed using the Unweighted Pair Group Method with Arithmetic Mean (UPGMA) agglomeration method, applied to each of four different distance metrics: Euclidean, Manhattan, maximum and Minkowski. Analysis based on hook measurement data in Suppl. materials 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21.
