EP001:
Anthropogenic Structures: Ecological Connectivity and Biological Effects


Session ID#: 28201

Session Description:
Worldwide, anthropogenic structures in the nearshore and offshore marine environment influence ecological connectivity of marine species (e.g. fishes, invertebrates, seabirds, marine mammals). These structures alter habitats where they are placed, and may modify physical and ecological processes in a number of ways, such as shifts in biodiversity and productivity. Examples include: 1) artificial structures positioned near biogeographical barriers may enable species to expand their ranges via a “stepping stone” process; 2) structures may alter trophic connectivity by enhancing prey resources; 3) altered connectivity may modify genetic structures. Understanding the potential environmental effects of novel habitat created by manmade structures is an important information need for managers when considering proposals for new construction projects. Compiling research results on ecological connectivity and biological effects of anthropogenic structures presents a timely opportunity for marine science to inform policy decisions at an international level. This session will provide a forum for the discussion of tools for analyzing connectivity, which includes ocean modeling of currents, propagule dispersal, genetic analyses, tagging studies, photographic and aerial surveys. This session will also elucidate potential ecological outcomes and cumulative effects from altered connectivity and the creation of artificial reef complexes in nearshore and offshore marine ecosystems.
