<p>In order to assess the relationship between the macrobenthic community and the sedimentary environment in Isahaya Bay, Kyushu, Japan, we conducted field surveys at 9 sampling stations in April 2014. Based on clustering analysis of abundance of the macrobenthic community, the 9 sampling stations were clearly divided into three groups(Groups A–C). The groups A–C were located at the outer(3 stations), center(2 stations), and inner(4 stations)parts of Isahaya Bay, respectively. Group A had low mud content(28.3±10.8%, mean±standard deviation)with low total organic carbon(TOC) (14.2±4.1 mg C g−1)and low acid volatile sulfur(AVS, 0.12±0.1 mg g−1). The dominant species in group A were a deposit- and filter-feeding amphipod, Photis longicaudata; a suspension-feeding bivalve, Veremolpa micra; and an omnivorous polychaete, Scoletoma longifolia. Group B had high mud content(74.6%)with high TOC(19.1 mg C g−1)but low AVS(0.20 mg g−1). The dominant species of this group was V. micra; a deposit-feeding bivalve, Theora fragilis; and a deposit- and filter-feeding amphipod, Ampelisca brevicornis. Group C had high mud content(87.8±4.8%), TOC(21.4±2.9 mg C g−1), and AVS(0.85±0.5 mg g−1)and was dominated by a deposit- and filter-feeding amphipod, Monocorophium sp.; T. fragilis; and a carnivorous polychaete, Glycinde sp. These results suggest that the distribution of macrobenthos corresponds with the sedimentary environment gradient in Isahaya Bay.</p>
