Fig. 3

Influence of Diplosoma listerianum colony density on total cover by fouling organisms. 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). Total cover relates to the effectively available tile surface area. Boxes and whiskers show medians, interquartiles and non-outlier ranges
