项目摘要

The quantitative and qualitative sampling on the freshwater and brackish water macro-invertebrates were conducted at more than 50 sites covering five islands belonging to the Ogasawara (Bonin) Islands, Japan during 2005-2007. As a result, four endemic species belonging to three arthropod orders and an alien thiarid species were newly found in the streams of these islands. At first, a new atyid shrimp of the genus Paratya is described based on the specimens collected from the head-water regions of Chichi-jima and Haha-jima. Secondary, a new caddisfy of the genus Goera is described from the streams of Chichi-jima. Third, a new flabelliferan isopod of the genus Gnorimosphaeroma is described from the streams of Haha-jima. And last, another new isopod of the genus Spherillo is also described from a reservoir of Haha-jima. During the course of this survey, an introduced thiarid snail of the genus Malanoides recorded from the streams of Chichi-jima for the first time.The surveys on the endemic chironomids were also conducted in the islands to assess their vulnerability. The habitats of Chironomus claggi, Cricoropus ogasaseptimus, Macropelopia ogasaseztdecima ant Tanytarsus ogasaquartus were confirmed based on larval collection from varous habitats. The larvae of Glyptotendipes tokunagai were collected at the shore of a reservoir in Hana-jima Island. This is the first record of Glyptotendipes from the oceanic islands.As for the caddisflies, even though an immature Rhyacophila larva was collected from Haha-jima, its taxonomic status and origin is still uncertain. On the other hand, the endemic species Goera ogasawaraensis showed a decline in its larval densities, compared with previous study. In relation to the two crustacean endemic species, declinations in population's size are observed, compared with study. Based on red list criteria, these three species were listed as endangered and threatened species by the Ministry of Environment, Japan.

2005-2007年，在日本小川(博宁)群岛五个岛屿的50多个地点对淡水和微咸水大型无脊椎动物进行了定量和定性采样。结果表明，在这些岛屿的溪流中新发现了3个节肢动物目4个特有种和1个外来种。首先，根据采集自赤岛和哈哈吉马水源地的标本，描述了一种新的异型虾属(Paratya)。其次，在赤岛溪流中记述了一新的戈拉属化石。第三，从哈哈-吉马溪流中描述了一种新的扇形类等足目动物--Gnorimsphaeroma属。最后，还描述了哈哈-吉马水库中的另一种新等足类Sphillo属。在这次调查过程中，首次从奇吉-吉马的溪流中记录到一种新引进的马兰属的旱螺，并对该岛特有的摇蚊进行了调查，以评估它们的脆弱性。根据对不同生境幼虫的采集，确定了克氏摇蚊、大仓鼠、大眼蜂的栖息地。在日本厦门岛的一个水库岸边，采集到了托库纳盖石斑鱼幼虫。这是大洋岛的首次发现。至于尸蝇，尽管在哈哈-吉马采集到了一只未成熟的嗜Rhyacophila幼虫，但其分类地位和来源尚不清楚。另一方面，与以前的研究相比，特有物种Goera ogasawa aensis的幼虫密度有所下降。与研究相比，对于这两个甲壳类特有物种，观察到种群规模的下降。根据红色名单标准，这三个物种被日本环境省列为濒危和受威胁物种。
