Influence of Diplosoma listerianum colony density on species richness of the establishing fouling communities. Settlement tiles were deployed at two sites in La Herradura Bay, Chile, over the course of 8 weeks. Tiles had different initial densities of Diplosoma listerianum colonies (white = 0, medium grey = 5 and dark grey = 15). On tiles that had initial Diplosoma listerianum cover, the species was only counted in case it recruited again during the experiment. Boxes and whiskers show medians, interquartiles and non-outlier ranges
