A Study on biological processes in estuaries

长崎大学的8名职员和南卡罗来纳州大学的5名职员在这三年中进行了交流，以交换科学信息，相互了解研究技术，并在每个研究领域进行研究。每一位来访者都在接待大学举行了一次研讨会，向工作人员介绍了自己最近的研究成果，并访问了邻近地区，与他们一起进行研究。一些研究样本被带回了所在大学进行额外的分析。以下研究部分是在东道国大学科学家的帮助下进行的，部分是一起进行的：河口动物的分布，草食性弹涂鱼的行为，采集弹涂鱼进行DNA分析，用免疫学方法研究潮间带甲壳动物的食性，河口动物的分布特点，捕食性天敌对斑胸轮虫卵的捕食作用、牡蛎幼体的化学感受作用、河口沉积物中休眠轮虫卵的分布。大弹涂鱼具有一种领地保护机制，但在繁殖过程中，这种机制暂时被破坏。它们的摄食活动加速了食用藻类的生产。对带回美国的日本弹涂鱼进行了初步的DNA分析，得到了很好的带型，这表明该类群的系统学研究有可能进一步开展。我们还发现了未来合作的可能性，在河口和食物分析与免疫学方法的固着形式的动物的化学传感器。

Eight staffs of Nagasaki Univ. and five staffs of the Univ. of South Carolina have been exchanged for these three years to enchange scientific informations, acquaint each other with research techniques and conduct research in each study field. Every visitor gave a seminar at the host university to give the staffs an introduction to the ground of recent own research and visited adjacent localities to conduct researches with them. Some research samples were brought back to the home university to conduct additional analyzes.Following researches were conducted partly with the aids of the scientists of the host university and partly together : distributions of estuarine animals, behavior of herbivorous mudskippers, mudskipper collection for DNA analyzes, feeding habits of intertidal cruataceans with immunological methods, characteristics in distributions of estuarine animals, predation of atherinid eggs by predators, chemosensory in oyster larvae, distribution of resting rotifer eggs in estuarine sedimentsWe have found so far the followings. The mudskipper, Boleophthalmus pectiniroustris have a kind of territory to protect their feeding area, but the mechanism is tmporarily broken during the period of reproduction. Their feeding activities accelerate the production of food algae. Tentative DNA analyzes on Japanese mudskippers they brought back to USA have brought about an excllent banding patterns, representing the possibility of future collaboration of the systematics of this taxonomic group. We also found the possibility of future collaborations on the chemosensory of sessile form animals in estuaries and food analyzes with the immunological method.
