Figure 1: Principal components analysis of Rowley Shoals octocoral communities. Each point represents the community recorded within a transect (points
close together having similar communities. (a) Colours identify transect depth; (b) same analysis as in (a), but here the colours are used to identify transect
location. Species vectors point at the communities (transects) where a species was best represented (species names are abbreviated to the first 5 letters).
