九州西廻り分布植物は, 亜熱帯性(南方系)の植物で, 琉球列島, 九州南部から九州西部(熊本・長崎県)を北上分布し, 九州東部(宮崎県北部・大分県)には分布していないものと定義され, 33種を確認した。九州西廻り分布型が成立するようになった理由を明らかにするために, 植物の生育型, 散布型, 生育立地, 気候, 地史について検討した。その結果, 最終氷期に海面が低下したために九州西部にできた広大な低地が亜熱帯性植物のレフュジアとなり, 氷期以後そこから分布を広げたことが九州西廻り分布植物の成立の主な理由と考えた。

Seeds of Macropsychanthus (Fabaceae) drifted on the coasts of Japanese islands were classified to seven species based on about 700 seed collections. The identified species were M.comosus (G.Mey.) L.P.Queitoz & Snak, M.ferrugineus Merr., M.hexander (Ralph) L.P.Queiroz & Snak, M.javanicus (Benth.) L.P.Queiroz & Snak, M.umbrinus (Elmer) L.P.Queiroz & Snak, M.wilsonii Standl.) L.P.Queiroz & Snak, and an unknown species(M. " mable " tentatively named). Most frequent seeds are M.hexander, which were about 80% of all drift seeds of Macropsychanthus. The following frequent species were M.wilsonii (5%), M.comosus (4%), M.ferrugineus (4%) and M.javanicus (3%). M.umbrinus and M. " mable " were rarely drifted and about 1%, respectively.The characters of their seeds were described.

1.アカザ科マツナ属(Suaeda)のヒロハマツナについて,分布の現状および群落の生態,特に植生単位を決定すると共に,ヒロハマツナと比較するために,日本のマツナ属すべてが産する九州西部においてそれらの詳しい分有を明らかにした.   2.ヒロハマツナの分布は,東海,近畿,中国,九州の11県から記録されているが,岡山県,福岡県,熊本県,鹿児島県ではすでに絶滅したか現状不明であり,愛知県では生育地が1ケ所,兵庫県,広島県,大分県では減少が著しく,絶滅が危惧される状況であった.現存する分布は南北に狭く,東西に広がっており,分布の東限は愛知県渥美町,西限は長崎県五島の若松町であった.   3.九州西部において,マツナは北東部のみで,対馬上島に最も生育地が多く,ハママツナはマツナ属の中で最も産地が多く,九州西部全体に分布していた.シチメンソウは有明海沿岸の佐賀県、長崎県に限られ,分布域に入る対馬には発見されなかったが,ヒロハマツナは対馬の浅生湾沿岸部,上五島,長崎県本土中北部の佐世保市,有明海湾奥部に分布していた.   4.ヒロハマツナは対馬と上五島のそれぞれ1ケ所においてハママツナと同じ塩湿地に,有明海湾奥部においてはしばしばシチメンソウと同じ塩湿地に生育していたが,混生することは少なく,すみ分けしていた.しかし,ハママツナとシチメンソウは同じ地点に分布していることはなかった.   5.ヒロハマツナの優占する群落を新群集としてヒロハマツナ群集Suaedetum malacospermaeを命名した.

NAKANISHI, Hiroki. (477-53,Ohte-machi, Nagasaki City). 1985. Geobotanical and ecological studies on three semi-mangrove plants in Japan. Jap. J. Ecol., 35 : 85-92. The three semi-mangrove plants ; Myoporum bontioides, Hibiscus hamabo and Paliurus ramosissimus were studied-geobotanically and ecologically. Distribution maps showing both the locality and size of communities dominated by the three species respectively were drawn. These species grow luxuriantly throughout the northernmost part of their distribution areas. The structure of disseminules and tests of buoyancy and viability in salt water proved that these species could disperse by sea currents. The species compositions and habitats of these communities were described. The Myoporum bontioides community is described as the new association Myoporetum bontioidetis which is usually monospecific. The association Hibiscetum is composed of only Hibiscus hamabo in the shrub layer and occasionally with some halophytes in the herb layer. The Paliurus ramosissimus community is invaded by many non-halophilous herbs. These semi-mangrove communities occur far more widely than the distribution areas of mangrove.

生産スケジューリング業務においてスケジュールに納期遅れジョブが発生した場合, 計画担当者は現有の設備・工数内で遅れジョブを出さないようスケジュールの改善を試みるが, 遅れジョブの発生が不可避と判断した場合には, 工場の保有能力を上位の計画部署より認められた許容範囲内で追加し遅れジョブの削減に努める.しかしながら, 最小の追加能力で納期遅れジョブ数を最小にするには, どの期間, どの設備に, どの程度の能力を追加すればよいかを決定することは難しい.ここではパラメータ空間探索改善法を能力追加を決定する問題に適用し, シミュレーション法に基づく系統的な能力調整法を提案する.さらに, 現実の計画条件データを用いてその方法の有用性を示す.

A total of 20 myrmecochorous plant genera and 19 seed-dispersing ant species were recorded from the warm-temperate zone of Japan. Of these plant genera, Akebia, Humulus and Lindera were newly found to be myrmecochorous. Akebia quinata, A. trifoliata and lindera citriodora, which had been regarded as mammal-or bird-dispersed species, seemed to be diplochorous, since their seeds contained in the faeces of mammals or birds were frequently observed being carried away by ants. The disseminule weight of the myrmecochorous species varied widely from 0.178mg (Corydalis racemosa) to 47.538mg (Akebia trifoliata), but was most frequently between 0.4mg and 2 mg. Unlike cool-temperate myrmecochores, which usually occur on the forest floor, warm-temperate myrmecochores were usually distributed in open or semiopen habitats such as at the forest margin, in cracks in stone walls, in grasslands and at the roadside. Seed dispersal occurred mostly from late spring to early summer, but occasionally took place even in autumn.

The history and present status of the conservation of <i>Hibiscus hamabo</i> Siebold et Zucc., which grows around salt marshes and is considered a semi-mangrove plant, were studied. Recently, several localities of this species have been designated as town, city, and prefectural natural monuments. The species is listed in the regional Red Data Book for most prefectures where it occurs. Citizens and government departments have performed numerous conservation activities. The conservation activities of citizens have varied, although some have incorrectly involved transplanting <i>H. hamabo</i> from other regions. It is important that conservation activities are carried out not only by citizens but also by government departments and researchers.

The vegetational zonation of sandy coasts in the San in District was studied in relation to depositional topography. The vegetation was divided into four zones (Z1-Z4). The first (Z1) was pioneer zone where only young plants were found in places. The second (Z2) was of grass communities which were divided into two subzones (Z2-a, Z2-b). Carex kobomugi was a dominant of Z2-a and Ischaemum anthephoroides of Z2-b. The third (Z3) was occupied by scrub demarcated by dominant growth of Vitex rotudifolia, and the fourth (Z4) was represented by plantations of Pinus thunbergii and Robinia pseudo-acasia. The Izumo coast faces north-west and receives prevailing NW-wind in winter and sand dunes develop. As dune height increases, Z2-a becomes narrower and Z2-b becomes wider. The Yumigahama coast, however, does not have prevailing winds in its front, so that dunes do not develop to make flat topography. The vegetation was found far from the shore-line. The Hojyo coast has well-developed dunes which are comparatively stable, because of the coarse beach sediments, leeward place and snow accumulation in winter. On the stable dune the narrow grasses of Z2 zone and Artemisia capillaris and Heteropappus hispidus var. arenarius on the third zone (Z3) were commonly found. The relationship between the zonation of the dune vegetation and topography was discussed with respect to the prevailing winds and the particle of the beach sediments.

This study was undertaken to describe and discuss the dispersal by ocean currents and the distribution of Ipomoea pes-caprae in the Japanese mainland. Frequency and growth of the seedlings from the sea-borne seeds were observed in Nagasaki Prefecture where the tropical drift fruits and seeds were the most frequent in Japan except the Ryukyu Islands. Based on my field observations and new records, a distribution map was constructed. More than 500 seedlings from the sea-borne seeds are estimated every year on beaches of Japanese mainland beyond the producing area where the plant passes the winter and completes the life cycle. The distribution of the producing area is expanded to the north. This may be due to the global warming.
