Abstract

Microcrustacean communities and chemical variables measured in Canadian saline lakes were analyzed to demonstrate the usefulness of plexus diagrams with the aim to elucidate structure in species-environmental complexes. Some of the alternative multivariate techniques to calculate and draw plexus diagrams were also examined. It was shown that, depending on the type of transformation of the rank correlation matrix, both the highly negative and the highly positive values can have the same effect, a tendency for points to get closer on the diagram. This type of plexus diagrams emphasises the high associations including negative relationships, like the avoidance of a habitat component. It is also shown that plexus diagrams are suitable to display community structure hierarchically by the strength of associations at different significance levels. The plexus diagram helped identify species preferring saline lakes, generalists, and species avoiding saline waters.
