PERMANOVA results comparing non-indigenous and native algal species percent cover and richness sampled from artificial and natural habitats.

Non-indigenous algal e) percent cover and f) species richness, native algal g) percent cover and h) species richness compared between vertical surfaces of artificial (pilings and pontoons) and natural (reef) habitats. Habitats were sampled at twice at 4 sites. Significant results (p<0.05) are indicated in bold.
