Pairwise comparisons of the 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 the vertical surfaces of artificial and natural structures. Habitat was the factor of interest in the comparisons and the direction of difference indicated in the left column. The sites and years at which these patterns occurred are indicated in the right column. Habitat  =  Pi (piling), Po (pontoon), Re (reef).Sites  =  BA (Balmain), CL (Clontarf), GB (Gore Bay) and FT (Fig Tree). Years  = 06 (2006) and 07 (2007).
