  • DISTRIBUTION OF CHOSENLA ARBUTIFOLIA AND SOIL TEXTURE OF HABITATS ALONG THE SATSUNAI RIVER

    The relationship between the distribution of seven salicaceous species and the soil texture of their habitats was studied in the floodplain of the Satsunai River, Hokkaido. Sandy and gravelly soils were common, but silty soil was very rare. Two groups of species were recognized : Salix species, Salix pet-susu, S. sachalinensis, S. rorida and S. gracllistyla, were dominant on the sandy soil, whereas a group composed of Chosenia arbutifolia, Toisusu urbaniana and Populus maximowiczii, predominated on the gravelly soil. C. arbutifolia was absent from the sandy soil, but was present in the alluvial fan zone, where the floodplain was wide and soil was very gravelly. P. maximowiczii and T. urbaniana were closely associated with the gravelly soil in the valley, where the floodplain was narrow. Indices of niche breadth and niche overlap showed S. sachalinensis and S. pet-susu to overlap widely, whereas C. arbutifolia had a narrow niche breadth and was segregated from the other salicaceous species. From these findings, a discussion is given of the relationship between geographical distribution and ecological traits of C. arbutifolia and the other salicaceous species in this study.

  • HOLOCENE VEGETATION HISTROY IN HAIBARA ON OMAEZAKI POINT, CENTRAL JAPAN

    A palynological study was made on the Holocene sediments of Haibara-cho, Haibara-gun, Shizuoka Prefecture. The pollen diagram was divisible into four local fossii pollen assemblage zones : OHA-I, OHA-II, OHA-III and OHA-IV. These zones were characterized by the high frequencies of Ptnus, Abies, Celtis-Aphananthe and Ulmus-Zelkova, by the dominance of Castonopsis, by the dominance of Castanopsis and the increase of Quercus (Cyclobalanopsis), and by the increase of Cryp-omeria and the high frequency of Q. (Cyclobalanopsis), respectively. The stratigraphical sequence of pollen in the core sediments, revealed the vegetation to be composed of a warm-temperate broad-leaved deciduous forest stage and a lucidophyllous forest stage. The lucidophyllous forest, composed of Castanopsis, formed 7500 years ago, and thereafter, a forest composed of this genus and Q. (Cyclobalanopsis) and Myrica spp. flourished from 6000 to 3000y. B.P. This trend was also observed in sediments from Lake Hamana, Shizuoka Prefecture. The present findings indicate that both this area and Lake Hamana were situated on the Pacific coast and were greatly influenced by the warm Kuroshio current and the rise in the sea level during the early Holocene.

  • PHOTOSYNTHESIS OF SUBMERGED LEAVES OF NUPHAR JAPONICUM DC. IN TAKAHAMAIRI BAY OF LAKE KASUMIGAURA, JAPAN

    The aquatic plant, Nupahr japonicum DC., is known to have aerial, floating and submerged leaves. An investigation on this species in Takahamairi Bay of Lake Kasumigaura revealed the photosynthetic rate of submerged leaves to be much lower than that of aerial leaves. It was hypo-thesized that the low water temperature in winter and the low photosynthetic photon flux density (PPFD) at the water bottom in summer act to limit photosynthesis by submerged leaves. Moreover, since submerged leaves utilize only free-CO2 the alkaline, low free-CO2 conditions of Takahamairi Bay may further act to limit photosynthesis via low ambient carbon availability.

  • FEEDING HABIT AND FOOD SELECTION OF THE GRAPSID CRAB HEMIGRAPSUS PENICILLATUS

    A laboratory investigation was made of the selection and consumption of natrrally occurring food items by adults of the grapsid crab Hemigrapsus penicillatus. Three categories of food items were investigated : the algae Enteromorpha prolifera, small conspecific individuals, and sessile matter composed mainly of detritus and diatoms. Adults fed on the internal organs of small conspecifics after removing the carapace. Sessile matter formed the major item, followed by E.proltfera and internal organs of small conspecifics, respectively. However, crabs starved for one day showed a strong food selection for small conspecifics with carapace removed over E. prolifera or small conspecifics without legs, with sessile matter being the least preferred food category. Following starvation, the frequency of contact with food items prior to eating increased for the less preferred categories.

    Since the great eruption in 1883,the Krakatau Islands have caught the attention of botanists, zoologists and ecologists worldwide. By synthesizing the findings of the large number of international scientists to have visited the islands for research, it has been possible to clarify the process of vegetational recovery. Based on a literature survey and some original research, plant successlon from pioneer communities in various habitats to a few types of forest, and two cases of biogeographical equilibrium were described. The influences of human interference and sterilization by the 1883 eruption upon vegetation recovery were discussed, and a seasonal forest was estimated to be a potential climax vegetation on the Krakatau Islands from the vegetation of neighbouring Panaitan Island. The importance of careful maintenance of plant and animal collections and records in long time studies, such as on the Krakataus, is emphasized.
