在这两年的美国-南斯拉夫合作研究项目 Dusan Srdoc，Rudjer Boskovic研究所 萨格勒布和波士顿大学的Stejepko Golubic， 调查人员将进行一个完整的案例研究， 典型的淡水系统。 这项研究将集中于 普里特维采湖和瀑布在岩溶地区的 南斯拉夫.我们的目标是找出 影响碳酸钙形成的活动 这些瀑布和沉积物。 一 将采用多学科方法。 南斯拉夫 研究团队拥有水化学方面的专业知识， 一般化学 生物学研究将是 由美国调查员进行。 美国科学家 将决定物种组成和生态作用 形成级联，并确定生物 矿物形成 这个项目是由美国批准的-南斯拉夫联合委员会 在科技合作方面， 通过由对等捐款组成的联合基金 来自美国和南斯拉夫政府 美国的捐款每年由该部提供 国家。 没有涉及NSF基金。 赠款提供给 南斯拉夫的主要科学机构，但 包括为美国科学家前往南斯拉夫提供美元资金 以及南斯拉夫科学家在美国的生活费。

In this two-year U.S.-Yugoslav cooperative research project in ecology between Dusan Srdoc, Rudjer Boskovic Institute in Zagreb and Stejepko Golubic at Boston University, the investigators will carry out a complete case study of a typical freshwater system. The study will focus on the Plitvice Lakes and waterfalls in the karstic region of Yugoslavia. The goal is to identify the principal biological activities that influence calcium carbonate formation of these waterfalls and travertine deposits. A multidisciplinary apporach will be used. The Yugoslav research team has expertise in aquatic chemistry and chemistry in general. The biological research will be carried out by the U.S. investigator. The U.S. scientist will determine the species composition and ecological role of organisms in forming cascades, and identify biological mineral formations. This project was approved by the U.S.-Yugoslav Joint Board on Cooperation in Science and Technology and is supported through a joint fund consisting of matching contributions from the governments of the United States and Yugoslavia. The U.S. contribution is provided annually by the Department of State. No NSF funds are involved. Grants are made to the principal scientific institution in Yugoslavia, but include dollar funds for U.S. scientist travel to Yugoslavia and for Yugoslav scientists' living expenses in the U.S.
