Table 2 Influence of the initial density of Diplosoma listerianum colonies (D), site (S) of exposure and weeks since start of the experiment (W) on the recruitment of the hydrozoan Obelia sp. on the effectively available tile surface area (total area—initial Diplosoma cover) during 8 weeks of fouling community succession

From: The colonial ascidian Diplosoma listerianum enhances the occurrence of the hydrozoan Obelia sp. during early phases of succession
