| Abstract | Hydrodynamic forces from waves and currents may have strong but different impacts on benthic diversity. In order to study the relative importance of current and wave expo- sure to the diversity of macrofauna associated with the kelp Laminaria hyperborea, we sampled fauna on epiphytic algae of 4 different morphological types from 27 stations in a crossed design with 3 levels of wave exposure and current speed. Fauna species number (S) was determined by morphology and amount (weight) of epiphyte and the interaction between wave exposure and current speed. Shannon-Wiener diversity H ' was determined by the epiphyte morphology and amount and degree of wave exposure. The most important factors for faunal community composi- tion were epiphyte morphology and wave exposure, and the effect of wave exposure was different for algae of different morphology. The most diverse fauna communities were found at intermit- tently wave-exposed sites and on large, rough epiphytic algae. The study shows that waves and currents influence kelp fauna communities very differently. Within our study area, waves had a stronger overall effect compared to currents. |
