摘要: Spatial heterogeneity in coral reef communities is well documented. This “species turnover” (beta diversity) on shallow warm-water reefs strongly conforms to spatial gradients the environment as spatially autocorrelated biotic processes such dispersal and competition. But extent which autocorrelation create beta diversity deep cold-water those formed by Lophelia pertusa (Scleractinia) unknown. The effects of remotely sensed ground-truthed data were tested community composition sessile suspension-feeding from Mingulay Reef Complex, a landscape inshore off Scottish west coast. Canonical correspondence analysis determined that statistically significant proportion (68%) variance could be explained environmental variables (northerly easterly aspect, seabed rugosity, depth), (species richness macrohabitat) geospatial location. variation was further partitioned into fractions pure (51%), structured (12%) (5%). Beta these reflected both measured unmeasured dependent vary across complex, i.e., hydrography. Future work will quantify significance relative contributions creating rich communities.
