| Table 9. Abundnces (mean +/- 1SE) per 0.04 m2 of dominant species in each of the clusters formed in the multivariate analysis of the Pellegrino and Hubbard (1983) data. The dendrogram is shown in Figure 19, the spatial distrubution of the clusters in Figure 20. Cluster identifiers (A, B, C1, etc.) are given along the top row. P (polychates), B (bivalves) and A (arthropods) indicate the beginning of each taxonomic group. | ||||||||||||||
