Abundance and Diversity of Holothuroids in Shallow Habitats of the Northern Red Sea

Figure 4

Discriminant analysis of holothuroid abundance by sampling site. This canonical plot shows the points and multivariate means in the two dimensions that best separate the groups. Labeled circles represent multivariate means for each site sampled. The size of the circles corresponds to a 95% confidence limit for the mean. Groups that are significantly different have nonintersecting circles. Labeled rays emanating from the grand mean show the directions of the variables (species) in the canonical space. CB—Coral Beach; JG—Japanese Gardens; IUI—Interuniversity Institute; LH—Lighthouse. Ab—Actinopyga bannwarthi; Bc—Bohadschia cousteaui; Bt—B. tenuissima; Ha—Holothuria atra; He—H. edulis; Hf—H. fuscogilva; Hl—H. leucospilota; Hn—H. nobilis; Sm—Synapta maculata; Sh—Stichopus horrens.
