Dendrogram solution for morphometric data of Temnothorax corsicus group species [29] in NC clustering using the UPGMA distance method.
The pattern is calculated from raw data of gyne specimens; the labels represent nest samples. Bars represent "kmeans" and "hclust” partitioning results returned by function PART.

Dendrogram solution for morphometric data of Temnothorax corsicus group species in NC clustering using UPGMA distance method.
The pattern is calculated from raw data of worker specimens, the labels represent nest samples. Bars represent “kmeans”, and “hclust” partitioning results returned by function PART.
