水田の多面的機能は、そこに生息する生物間の相互作用に負うところが大きい。水田にキーストーン捕食者である魚を放流して魚を放流しない水田と比較すれば、対照区つきの隔離水界実験(メソコスム実験)になり、水田の生物間相互作用を解明する上で有効である。水田にカダヤシを放流しても、カに対する抑制効果が見られないことがある。カダヤシはカの幼虫・蛹のほかに、その捕食者や競争者も食べるので、捕食による効果の総和が必ずしもカを減らす方向に働かないためである。メコン川デルタの水田に3種の魚を放し、魚を放さない水...

カラー魚群探知機を用いて、琵琶湖南湖の沈水植物の分布・現存量・群落容積を調査した。まず、魚探の画像をビデオに記録し、画像解析によって沈水植物の密度を推定するモデルを作成した。500mピッチ27測線の航測結果から2003年夏の沈水植物の分布面積は36-38km2と推定された。沈水植物の平均密度は8月4日から9月30日まで増加し、165gm-2に達した。この値から南湖の沈水植物の総現存量は乾燥重量で約8580tと推定された。

ラオスでは焼畑にかわる定住型で生産性の高い稲作の場として水田の重要性が増している。ラオス北部のベン川流域において6つの水田の藻類群集について調査した。これらの水田では農薬、化学肥料、農業機械などは用いられていない。培養法によって得られたラン藻や緑藻の量は105_から_106CFU g-1 soilで、これまでに熱帯アジアおよび日本の水田から報告された藻類量の範囲にあった。一方、直接計数によって得られた珪藻量をみると、多いところでも103_から_104 cells g-1 soilでほとんど...

Crucian carp larvae showed rapid growth in paddy fields. The standard body length increased linearly except for the post-larva stages after they consumed cladocerans. This pattern suggests that the assimilation rate was usually much higher than th...

In recent years, modern farming techniques have been introduced into traditional paddy fields in northern Laos. In this study we investigated characteristics of algal communities which indicate changes of paddy field ecosystem.1. Surveys were cond...

Identifications of fishes are very important for ichthyologists and fisheries biologists who need to know names of fishes. However, it is usually difficult to exactly identify fishes because there are so many similar species in diversified groups ...

1. We determined vertical changes in flow velocity and dissolved oxygen saturation in biofilms on artificial and natural substrates using microelectrodes. Vertical profile of current velocity versus depth indicated a presence of viscous sublayer. ...
