constellation diagram

Show Summary Details

Quick Reference

A representation of species affinities that is based on c2 as a measure of the association between species. The reciprocal of the c2 value for each species pair is used to plot the diagram, so that highly positively associated species with large c2 values are positioned closely together. Thus clusters of similarly distributed species may emerge, while the transitional affinities of a species with those of another main focal area or cluster will be evident. The constellation diagram exemplifies a simply calculated ordination method.
