Species composition, distribution and community structure of intertidal rocky shore macrobenthos in Pathiew, Chumporn were investigated quantitatively in August 2007 and February 2008. A total of 49 species of macrobenthos were identified with 1 species of sponge, 1 species of platyhelminth, 11 species of annelids, 15 species of molluscs and arthropods, 3 species of echinoderms, 1 species of bryozoan, and 2 species of chordates. A gastropod, Clypeomorus b. bifasciata, was the dominant taxon occurring with the high density at the mid and lower shore level whereas the densities of other macrobenthos species tended to increase with the distance from the supralittoral shoreline. Based on the results of SIMPER Analysis, two groups of communities were... |
