Parthenogenetic Reproduction and It's Correlation to the Presence of a Single Trematode Parasite in Freshwater Snails

淡水蜗牛孤雌生殖及其与单一吸虫存在的相关性。该奖项是根据1987/1988年美国-工业化国家科学家和工程师交流计划竞赛提出的。该计划旨在帮助西欧工业化国家以及日本、澳大利亚和新西兰的机构。交流奖为开展联合研究和利用国外独特或互补的设施、专门知识和实验条件提供了机会。奖项的评选依据是与其所在科学领域相关的科学标准、科学和工程领域国际合作申请者的预期潜力。该计划特别针对正在开始他们的研究生涯的科学家和工程师。这项研究项目将解决淡水蜗牛孤雌生殖能力与单一吸虫寄生虫存在之间的相关性问题。这项研究的目的是直接检验先验预测，即有性蜗牛比无性蜗牛更能抵抗吸虫寄生虫的感染--这是由寄生虫引起的自然选择维持性别的必要条件。该项目由美国亚利桑那大学图森分校生态与进化生物学系柯蒂斯·M·莱弗利博士和新西兰克赖斯特彻奇1号坎特伯雷大学动物系主任C.L.麦克莱博士指导。这项奖励建议提供资金，酌情支付国际旅行、当地出国旅行、津贴、家属津贴(如果适用)、语言培训(如果需要)，以及为美国本土机构提供250美元的固定行政津贴。

Parthenogenetic Reproduction and It's Correlation to the Presence of a Single Trematode Parasite in Freshwater Snails. This award recommendation is made under the U.S.-Industrialized Countries Program for the Exchange of Scientists and Engineers, 1987/1988 Competition. The program is designed to enable institutions in the industrialized countries of Western Europe as well as Japan, Australia and New Zealand. Exchange awards provide opportunities for the conduct of joint research and the utilization of unique or complementary facilities, expertise and experimental conditions in foreign contries. Awards are selected on the basis of scientific criteria relevant to his/her field of science, the prospective potential of the applicants of international cooperation in science and engineering. The program is particularly directed to scientists and engineers who are embarking on their research career. This research project will address the problem of correlation between the capability of the freshwater snail, Potamorpyrgus Antipodarum, of parthenogenetic reproduction and the presence of a single trematode parasite. The purpose of this study is to directly test the a priori prediction that sexual snails are more resistant to infection by the trematode parasite than are asexual snails - a necessary condition for the maintenance of sex by natural selection resulting from parasitism. The project is under the direction of Dr. Curtis M. Lively, Department of Ecology and Evolutionary Biology, University of Arizona, Tucson, AZ 85721, U.S.A., and Dr. C. L. McLay, Head, Department of Zoology, University of Canterbury, Christchurch 1, New Zealand. This award recommendation provides funds to cover, as appropriate, international travel, local travel abroad, stipend, dependents allowance, if applicable, language training, if required, and a flat administrative allowance of $250 for the U.S. home institution.
