Table 1. Design of recruitment and community development 



experiments. Settling plates are held on vertical 

 rocks separated from the substratum, granite blocks are 

 in contact with the substratum and are thus available 

 to all benthic predators. N = no. replicates per 

 depth, C = collected, S = sampled, F = future 

 collection.
