Resource utilization and interspecific relationships shore animals.

1.博尔德海岸群落：我们发现两种布氏科蜗牛具有两种摄食模式；以腐肉为食，捕食其他蜗牛。调查了两种植物的详细分布。澄清了潮间带和潮下带的群落结构，并阐明了卵石大小和构造对群落结构的影响。详细调查了5种帽螺的垂直分布格局，并通过定居后的垂直迁移确定了其垂直分布格局的差异。通过田间圈养试验，阐明了潮间带海参的双向性别变化。岩岸群落：死藤壶的壳板被保留下来，壳中的空间被小生物利用。小型移动软体动物偏爱小藤壶（Chthamalus challengeri）。另一方面，大型藤壶，日本四小龙被利用了几组动物；软体动物、甲壳类、多毛类等。藤壶壳影响了一些小型生物的垂直分布。潮下群落：生境对海胆聚集的影响，经实地观察及室内实验证实。研究了水深对某些硬核珊瑚生长、繁殖和招募的影响。

1.Boulder shore community : We showed two species of Buccinidae snail had two feeding mode ; carrion-feeding and hunting other snail. Detailed distribution of two species were investigated. Community structures on the intertidal and subtidal area were clarified, and the effects of boulder size and construction on the community structure were clarified also. Vertical distribution patterns of relative five species of limpet snail were investigated in detail, and defference of vertical distribution pattern of these species were determined by vertical migration after settlement. Two-direction sex change of an intertidal sea cucumber was clarified through field cagingexperiment.2.Rocky shore community : Shell plates of dead barnacle were remained, and the space in the shell was utilized by small organisms. The small barnacle, Chthamalus challengeri were preferred by small mobile mollusks. At the other hand, the large barnacle, Tetraclita japonica was utilized several group of animals ; mollsuca, crustacea, polychaeta etc. Barnacle shell influenced the vertical distribution of some small organisms.3. Subtidal community : Shelter effect on gathering of a sea urchin was shown by field observations and laboratory experiments. Water depth effect on growth, reproduction and recruitment of some scleractinian coral species were investigated.
