DISTLM of the densities of Cirolana harfordi in oyster-beds, using Thickness of the habitat, Concentration of organic matter smaller than 64 µm (OM<64), Concentration of organic matter between 64 and 500 µm (OM 64–500) and Location as predictor variables. For marginal tests, variables are taken individually; for sequential tests, variables were chosen using Forward selection criteria. The column %var indicates the percentage of the variation explained by the predictor variables. Cum % is the cumulative percentage of variance explained.
