FIGURE 133. Separation of nest samples of Cardiocondyla elegans (grey bars) and C. dalmatica (black bars) by NC-Ward, NC-part.hclust, NC-part.kmeans and NC-NMDS.kmeans clustering. White bars indicate outliers in NC-part.hclust. The mean classification error of the four exploratory data analyses relative to the controlling linear discriminant analysis is 1.2%. Fourteen phenotypic characters were considered. The bimodality within both species' clusters represents an intraspecific dimorphism (Seifert 2016).
