【 摘 要 】

ABSTRACT: Boulders are an important substrate for Baltic Sea benthic communities. Although previous studies have examined benthic species on sublittoral boulders in the Baltic Sea, information on benthic assemblages and how they vary in relation to structuring factors is limited. The aim of the present study was to describe the benthic communities, including both algae and animal taxa, on sublittoral boulders in relation to spatial positions on the boulders (4 levels) and differences in wave exposure (2 levels). The multivariate results, including 29 algae and 25 animal taxa, from the field sampling showed a significant interaction between the 2 main factors. Changes in the biomass of both annual an perennial macroalgae as well as
