A-D Redundancy analysis of the environmental variables and infracommunity metrics of the parasites of Syacium gunteri . (A) The RDA for all sampling sites accounted for 36% of the total variance, and was highly significant for the first and all four canonical axes (F = 51.46; P-value = 0.0002; 4999 permutations) for the 33 sampling stations. (B) For group 1, the RDA accounted for 35% of the total variance, and was highly significant for the first and all four canonical axes (F = 51.46; P-value = 0.0002; 4999 permutations). (C) For group 2, the RDA accounted for 23% of the total variance, and was highly significant for the first and all four canonical axes (F = 14.10; P-value = 0.03; 4999 permutations). (D) For group 3, the RDA accounted for 68% of the total variance, and was highly significant for the first and all four canonical axes (F = 38.24; P-value = 0.03; 4999 permutations).
