The response of some common fouling organisms to increased predation by scraping and decreased predation by caging is described. Substrate coverage by many colonial forms such as Perophora viridis and Diplosoma macdonaldi was not affected by changes in predation intensity whereas coverage by many solitary forms such as Spirorbis sp. and Styela plicata increased when predation was reduced. These differences in responses of colonial and solitary species may be because solitary species reproduce sexually and resettle newly opened space whereas colonial species can rapidly expand adjacent colonies into newly cleared space.

... To date, few controversial field caging experiments, where all the predators larger than mesh cell size were excluded, provide almost opposite results depending on the system studied. Total predator removals favor solitary tubeworms and ascidians against colonial ascidians (Mook, 1983), colonial ascidians against solitary ones (Hiebert et al., 2019), and recruits of colonial bryozoans against solitary tubeworms and cirripeds (Sowa et al., 2023). Other field experiments do not show advantages in tolerating consumer control distinctly associated with unitary or modular organization (Osman et al., 1992;Sams & Keough, 2007;Vieira et al., 2012). ...
