Redundancy analysis (RDA) results on relationships between megabenthic biomass-based taxonomic composition and environmental variables for a subset of 50 stations sampled from 2008 to 2011.

Two RDA analyses were performed, with and without spatial variables, and both were significant (p<0.001; 9999 permutations). Results from the first two RDA axes are shown and environmental variables are listed in order following forward selection (9999 permutations).
