Figure 2

Overlaid contour and classed post maps (surfer) of SADIE clustering indices for counts of the species assemblages identified in the CA. Index values > −1.5 represent significant gaps (blue shading and darker blue dots), and index values >1.5 indicate significant patches (red shading and darker red dots). Black dots indicate units for which clustering exceeds expectation, although not significantly (>2 or < −1). Open dots indicate clustering below expectation (<1 or > −1).
