| hard coastal-defence structures as habitats for native and exotic rocky-bottom species. | the use of hard coastal-defence structures, like breakwaters and seawalls, is rapidly increasing to prevent coastal erosion. we compared low-shore assemblages between wave-protected and wave-exposed habitats on breakwaters along a sandy shore of tuscany (north-western mediterranean). assemblages were generally characterized by a low diversity of taxa, with space monopolized by mytilus galloprovincialis and corallina elongata on the seaward side of breakwaters and by filamentous algae on the land ... | 2008 | 18656256 |
