Abstract：
In 1971, scientists from Mahidol University in Thailand and the Smithsonian Institution in the USA formed a research team to study a new species of Schistosoma in the Mekong River in Thailand and Laos. The studies, completed during 1971-1973, prior to the construction of any dams or restrictions to the natural flow regime of the Mekong River, provide a unique description of the natural ecological state of the river that can serve as a baseline for current research. The natural transmission of Schistosoma japonicum, Mekong Strain, was first reported on Khong Island, Laos in 1973 using sentinel mice. The first detailed description of the habitat ecology of the snail vector Neotricula aperta was done on-site in 1971 simultaneously with that research and is unique in providing the only description of the river shoreline habitat before any dams were built and any alteration of the natural flow regime was in place. Aggregating current information in a Place-Based Conceptual Model (PBCM) as an organizing template, along with current habitat models that combine ecological data with e-flows, can be developed and used as a tool to predict suitable habitats for snails. The natural flow regime of the Mekong River prior to any impoundments is described with current updates on the potential impacts of climate change and dams with flow-related snail habitat characteristics, including sediment drift and water quality. The application of the PBCM to describe and compare descriptive information on current and potential future N. aperta/S. mekongi habitat is discussed.
摘要：
1971年,泰国玛希隆大学和美国史密森学会的科学家组成了一个研究小组,在泰国和老挝的湄公河地区研究一种新的血吸虫物种。研究,在建造任何水坝或限制湄公河自然流态之前，于1971-1973年完成，提供对河流自然生态状况的独特描述，可作为当前研究的基线。日本血吸虫的自然传播,湄公河毒株,最初是在Khong岛报道的，老挝1973年使用前哨老鼠。对蜗牛媒介Neotricataaperta的栖息地生态学的第一次详细描述是在1971年与该研究同时进行的，并且在建造任何水坝和任何自然流态改变之前提供了对河流海岸线栖息地的唯一描述是独一无二的。将基于地点的概念模型(PBCM)中的当前信息聚合为组织模板，以及当前将生态数据与电子流相结合的栖息地模型，可以开发并用作预测蜗牛合适栖息地的工具。描述了在任何蓄水之前湄公河的自然流量状况，并提供了有关气候变化和具有与流量相关的蜗牛栖息地特征的大坝的潜在影响的最新信息。包括泥沙漂移和水质。PBCM在描述和比较当前和潜在未来N.aperta/S的描述性信息中的应用讨论了mekongi栖息地。
