134. Trawl data multivariate analysis was carried out including the numerable taxa with their full abundance data; the presence of the colonial species was accounted for by giving the non‐numerable colonial species an abundance of one. The cluster and ordination analysis highlighted one main faunal grouping formed by 9 sites (group d) and three minor groupings formed by 3 single sites (groups a, b and c).
135. Cluster analysis and the correspondent 2D multi‐dimensional plot are presented in Figure 3.18.
