Estruturas de comunidades de animais de solo e sobrevivência dos caracóis terrestres numa ilha do Arquipélago Ogasawara

On Chichijima, one of the Ogasawara (Bonin) Islands located in the Western Pacific Ocean, land snails have declined, the suggested cause being predation pressure by an invasive flatworm (Platydemus manokwari). Soil fauna were investigated in areas where the snail survives, and where it has become extinct. Much of the fauna, dominated by introduced earthworms and ants, was undiminished, however, one undescribed but endemic carabid (Badister sp.), which selectively feeds on land snails, was absent in snail-extinct areas. The invasive flatworm P. manokwari has been reported to feed also on the carcasses of earthworms, as well as on live snails, and is therefore expected to occur in most parts of Chichijima Island. Among other groups, the density of isopods (also dominated by exotic species) was very low, in comparison with the reported ones 30 years ago. Community structure is currently reflected by dominance of earthworms and ants, decline of endemic isopods, and a high frequency of introduced or alien species.Em Chichijima, uma das ilhas do Arquipélago Ogasawara (Bonin), localizado no Oceano Pacífico Ocidental, o número de caracóis terrestres diminuiu, e a causa provável é a predação por uma planária invasora (Platydemus manokwari). A fauna edáfica foi avaliada nas áreas onde o caracol sobreviveu e onde se extinguiu. Grande parte da fauna, dominada inicialmente por minhocas e formigas, não diminuiu; contudo, um carabídeo endêmico e não descrito (Badister sp.), que se alimenta de caracóis terrestres, não estava presente nas áreas em que o caracol foi extinto. Sabe-se que a planária invasiva P. manokwari se alimenta não só das carcaças das minhocas, mas também de caracóis vivos, e por isso habita a maior parte da Ilha Chichijima. Entre outros grupos, a densidade de isópodos (também dominados por espécies exóticas) foi muita baixa, em comparação aos relatos feitos 30 anos antes. A estrutura da comunidade é refletida atualmente pela dominância de minhocas e formigas, declínio de isópodos endêmicos, e uma alta frequência de espécies introduzidas ou exóticas

The Kitakyushu City area, in which the University of Occupational and Envionmental Health, Japan (UOEH) campus lies, is situated in the region of the evergreen broad-leaf, or laurel-leaf, forests. Our studies on relict forest stands revealed that the original forest communities in the area were Cyrtomio-Litseetum japonicae and Euonymo-Pittos-poretum tobirae in the coastl area, Arisemato ringentis-Machiletum thunbergii in the bottomland, Symploco-Castanopsietum sieboldii and Ardisio-Castanopsietum sieboldii in. foothill area, and Distylio-Cyclobalanopsietum stenophyllae, Actinodaphnetum lancifoliae and Skimmio-Cyclobalanopsietum acutae on the mountain slopes. The secondary forests in the area are Castanopsis-Cyclobalanopsis coppice of sprout origin, red-pine forest and deciduous forests of various dominants. The original forest on the UOEH campus is assumed to be Symploco-Castanopsietum sieboldii, an evergreen broad-leaf forest, some 25m high and I m dbh in canopy trees. The secondary forest on the campus is doin inated by Quercus serrata, accompanied by Rhus succedanea, Platycarya strobilacea and Castanopsis cuspidata var. sieholdii. A small wetland near the north gate is dominated by Typha angustata. Slopes on the campus, which were created by cutting-off or fillingup of the ground, are invaded by Miscanthus sinensis, Solidago altissima (alien) and many other herbaceous plants. One hundred and thirty-six species of flowering plants and eight specles of ferns were recorded from the campus. Conservation problems are discussed from the standpoint of vegetation science.1)医生ケ丘をふくむ北九州市西部は, 全域が照葉樹林域にある. 残存林分の調査によって, 沿岸地帯-内陸の原植生が推定され, 医生ケ丘一帯はスダシイ-ミミズバイ群集域であることが明らかとなった. 2)現存植生の二次林は, シイーカシ萌芽林とカラスザンショウ群落が優勢である. 医生ケ作の二次林では, コナラが優占し, ハゼノキ・ノグルミが常に出現する. 向陽地では林床にウラジロまたはコシダが優占している. 3)湿地にはガマ・ヒメガマ・イグサが優占する. 4)医生ケ丘で種子植物131種, シダ植物8種を記録した. 5)大学構内の緑化について, 植生学の立場から付言し, 特に残存林および西北部の湿原群落の保存の重要性を指摘した

The phytosociological study on vegetation was done in northwestern Kitakyushu City and its vicinities. Kitakyushu City is located in the northern region of Fukuoka Prefecture. The following I 3 associations or communities were identified and described, Natural forests were as follows; (1) Euonymo-Pittosporetum tobirae, (2) Cyrtomio-Litseetum japonicae, (3) Aphananthe , aspera Community, (4) Arisaemeto ringentis-Machiletum (Perseetum) thunbergii, (5) Symploco glaucae-Castanopsietum sieboldii, (6) Carpinus tschonoskii-Castanopsis cuspidata var. sieboldii Community, (7)Distylio-Cyclobalanopsietum, (8) Skimmio-Quercetum acutae Substitutional forests and afforestations were (9) Castanopsis coppice forest, (10) Pinus thunbergii afforestation, (13) Phyllostachys heterocycla var. pubescens afforestation. The number of character species in some associations we studied was fewer than the same ones found in Nagasaki Prefecture, western Kyushu. The standing vegetation map was drawn on the scale of l:50,000. Small natural forests were remained on particular sites. Secondary forests and afforestations of Cryptomeria japonica and Chamaecyparis obtusa were distributed widely on hills and mountains. The ranges of forests have been contracted by the expansion of urban districts and orchards. Urban and industrial areas were the most predominant landscapes in the study area.

Fifty forest stands and sixty plant species were ordinated by a reciprocal averaging (RA) method to extract the major vegetation patterns of the forest in northwestern Kitakyushu City and nearby areas. The RA stand ordination on the first and second axes revealed three gradients of vegetation. They are the gradienLs (1) from the Quercus serrata-dominatcd forest to the Machilus thunbergii- or Aphananthe aspera-dominated forest, (2) from the Quercus- to the Castanopsis cuspidata-dominated forest, and (3) from the Aphananthe- or the Machilus- to the Casianopsis-dominated forest. The first two gradients showed high correlations of the stand RA scores to the canopy height and to the number of species found in the stand, but the third one did not. The former two, therefore, were referred toas the successional series of forests on the moist (bottomland) habitat and that on the less moist (foothill) one, respectively, and the third as the environmental gradient from moist to less moist habitats in matured forests. The RA species ordination showed the distribution center of each species in the above rnentioned patterns of the forest vegetation(Received 15 February 1984)医生ケ丘をふくむ北九州市北西部および近隣地において, 森林群落50スタンドを調査した. それらを優占種により分類すると, コナラ群落, タブノキ群落, ムクノキ群落, シイノキ群落であった. 50スタンド, 60種の群落資料を反復平均法により解析した結果, 次の三つの植生の系列が明らかとなった. (i)コナラ群落一タブノキ群落-ムクノキ群落, (ii)コナラ群落-シイノキ群落, (iii)タブノキおよびムクノキ群落-シイノキ群落. 前2系列は樹高の増大および種類の増加と有意の相関をもつ森林の群落遷移の系列であり, 第3の系列ではそれらと相関がなく, 環境傾度上の系列であることが明らかとなった
