constellation diagram

views updated

constellation diagram A representation of species affinities that is based on χ2 as a measure of the association between species. The reciprocal of the χ2 value for each species pair is used to plot the diagram, so that highly positively associated species with large X2 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.
