| 研究内容要約 Research Summary |
調査は多摩川の下流部に流入する大栗川、野川（１９８７年８月・１９８８年１月）、中流部に流入する浅川、残堀川（１９８８年８月・１８８９年１月）、上流部に流入する秋川、平井川（１９８９年８月・１９９０年１月）を対象にし、夏、冬年２回の採集を行った。 現地では定性材料と、定量材料を採集し、ホルマリンで固定後持ち帰った。 定量材料は検鏡を行い、各地点ごとに種類構成を計測した。 定性材料はクリーニングをし永久プレパラート作成後顕微鏡写真に撮影し、特に分類学的に用いる種については２０００倍に引き伸ぱした約３００固体の写真から検討を進めた。 In this study, water samples were collected twice a year (summer and winter) from six rivers: the Okuri and Nogawa Rivers (August 1987 and January 1988), which joins the lower reaches of the Tama River; the Asaｇawa and Zambori Rivers (August 1988 and January 1989), which join the middle reaches of the Tama River; and the Akigawa and Hirai Rivers (August 1989 and January 1990), which join the upper reaches of the Tama River There we collected quantitative and qualitative samples, which were formalin-fixed to allow bringing them back. Quantitative samples were observed under a microscope, and then samples from each collection site were analyzed to determine the components. After the qualitative samples were analyzed, we made permanent preparations which were microscopically photographed. Photographs of 300 species were enlarged to 2,000 times in order to be taxonomically analyzed. |
