2.3.1. Community ecological analysis
An interactive tree first allows the user to make a taxon preselection. Then, when the cursor is placed in the taxonomic classification text field, an auto-completion feature assists the user in defining a more specific taxonomic range. The resulting beta-diversity calculation option provides a nMDS ordination from either a Bray-Curtis dissimilarity matrix if the ”Bray-Curtis dissimilarity” option is selected or a Jaccard distance matrix if the ”Jaccard index” option is selected.
