我们研究了盐生植物，腹足类，和brachyurans在盐沼（52个站点）在有明和八代海的西日本的物种组成和群落结构，并评估了非生物和生物环境因素驱动的群落结构。此外，群落结构的差异进行了比较的三个主要研究领域：有明海域，八代海域，和Uto-Amakusa地区（海岸线网站之间的有明和八代海）。共记录盐生植物11种，腹足类19种（组），短尾纲19种。盐生植物种类的平均数以上户天草地区最多，但腹足类和短尾纲种类的数量在三个地区之间相似。对于每种盐生植物、腹足类和短尾纲物种，有明和八代海域的群落组成与宇藤天草海域有很大差异，而有明和八代海域的群落组成相似。盐生植物物种的差异主要是由高，密集的芦苇的存在。此外，影响群落结构的最重要的环境因素是盐生植物和短尾类的间隙水盐度，以及腹足类与开阔海岸线的距离。
We examined the species compositions and community structures of halophytic plants, gastropods, and brachyurans in salt marshes (52 sites) in the Ariake and Yatsushiro seas of the western Japan, and assessed the abiotic and biotic environmental factors driving the community structures. Moreover, differences in community structures were compared among the three main study areas: the Ariake sea area, Yatsushiro sea area, and Uto-Amakusa area (shoreline sites located between the Ariake and Yatsushiro seas). A total of 11 halophytic plant species, 19 gastropod species (groups), and 19 brachyuran species were recorded. The average number of halophytic plant species was the highest in the Uto-Amakusa area, but the numbers of gastropod species (groups) and brachyuran species were similar among the three areas. For each halophytic plant species, gastropod species (groups) and brachyuran species, the community composition in the Uto-Amakusa area differed greatly from that in the Ariake and Yatsushiro sea areas; however, those of the Ariake and Yatsushiro sea areas were similar. The dissimilarities in halophytic plant species among the areas were driven mainly by the presence of tall, dense Phragmites australis. Moreover, the most important environmental factor that affected community structure was interstitial water salinity in halophytic plants and brachyurans, and distance from the open shoreline in gastropods.
