Research Abstract

In rocky shore, population studies on sessile barnacles were carried out. In Chthamalus challengeri, a small high intertidal species, distinct differences were observed among different tide level sub populations in both reproductive characteristics and demographic population sequences. Total reproductive out put and settled recruits were estimated for each subpopulation, and the population persistence mechanisms were discussed. Long-lived black barnacle and a goose-neck barnacle were also studied. On the other hand, one of the most powerful grazer, common Japanese chiton was investigated for its grazing and bulldozing impact using the inclusion/exclusion cage experiment. Mobile grazing mollusk guild on the boulder shore is also examined for their space and food utilization.
For epiphytic amphipod crustacea, population dynamics of caprellids on the Sargassum which shows drastic seasonal fluctuation of algal biomass. The fate of epiphytic animal at the algal drifting season was investigated by artificial drifting experiment, species specific response were recorded among Caprellids. Maternal care habits were discovered in a few caprellids, and its significance for offspring survival was discussed in the context of reproductive strategy.
For ecology of reef building corals in the northern periphery of distribution range, fauna and ecological distribution patterns were investigated by intensive underwater works. Possibility of sexual reproduction in the temperate environment was examined both in the field and aquarium observation, sexual reproduction was confirmed in 13 species and 2 morphs of corals, and lunar periodicity of spawning was examined.
