Examining how landscapes influence benthic community assemblages in seagrass and mudflat habitats in southern Maine

► Seagrass increases abundance and diversity of fish and invertebrate communities. ► Fish and native mobile crustaceans were most abundant in and adjacent to seagrass beds. ► Seagrass proximity influences mudflat community structure through predator access. ► Degrading biogenic habitats alters community structure and impairs ecosystem function.
