P245-04 Distance effects on short-term recolonization of Sargassum stenophyllum by mobile epifauna, with an analysis of gammarid life habits Tanaka MO, Leite FPP Dispersal by adults of species with direct development can influence patterns of aggregation and structure of assemblages associated with habitat patches, because distance among patches can influence both movement abilities and predation risk during dispersal. Here we experimentally evaluated whether distance between patches of the brown alga Sargassum stenophyllum relative to the algal bed influenced colonization patterns by mobile epifauna and gammarid amphipods with distinct life habits. Amphipods were the dominant group, commonly dispersing to patches up to 8m distant from the algal bed, with low densities of other groups. Assemblage structure of both faunal groups and gammarid amphipods on defaunated algae generally converged to that of controls during the experiments in less than 8 days. Gammarid amphipods were dominated by tube-dwellers, but free-living nestlers also colonized the available substrate, and both reached control densities during the study. The same pattern was observed for representative species within each group. Colonization rates were related to faunal densities on the algal bed for most groups, suggesting that mobile organisms disperse more to new habitat patches in high density conditions. Thus, species with direct development can rapidly establish new aggregations at favourable sites, and contribute to small-scale heterogeneity in faunal distribution.
