Abstract
Patterns of benthic colonization and succession were investigated on a temperate rocky cliff (Aegean Sea, Eastern Mediterranean). Cement and ceramic panels deployed on the rocky substratum at 25-30Â m depth were sampled every 3Â months over a 2-year period yielding 28 floral and 156 animal species. Diversity, cover and abundance had low values at short immersion periods and increased at the long ones. The vagile fauna responded to the increasing habitat complexity offered by the development of algal turfs and sessile species, and the community structure remained highly dynamic. Unlike the duration of immersion, the type of substratum didn't affect species colonization except for decapods that showed a preference for cement panels. Three to four stages of succession were recorded over immersion periods, according to vagile and sessile biota, respectively, during which species richness and abundance increased. The structure of the developed communities on both artificial materials differed from the natural algal-dominated benthic community of the same area, suggesting that the recovery of rocky shore communities on temperate cliffs is time consuming.
