From: Identifying areas and centers of endemism in the Gran Chaco with Fabaceae as a diversity indicator
Cluster Analysis and mapping of Centers of Endemism (CEs) by means Unweighted Pair Group Method with Arithmetic Mean (UPGMA) of the Gran Chaco ecoregion based on endemic and highly restricted Fabaceae, calculated with the Jaccard similarity index. This analysis includes only cells with nine or more occurring taxa. Grey thin lines delimitate the three subregions of the Gran Chaco ecoregion.
