Results of cluster and MDS analyses of Tasmanian seamount biota binned by 100 m depth strata.

Numbers indicate the upper depth of the strata X 100 (e.g., 6 = 600–700 m). The green and dashed blue horizontal lines in the cluster analysis and the outlines in the MDS indicate 35 and 45% levels of similarity, respectively, based on the Bray-Curtis similarity index of square-root transformed mean number of individuals in each identified taxon in images in each depth stratum. Vertical red lines in the cluster analysis indicate linkages that are interchangeable at the 95% confidence level. Clusters (see key) were identified at the 40% similarity level, except for the 3200–<4100 m group that showed no significant internal structure at 40% similarity.
