The Amazon Basin is Earth's most biodiverse watershed, yet much remains unknown about species diversity, population structures, biogeographic ranges, and ecological and evolutionary processes. This project will document and analyze the aquatic biodiversity of a 130 km-long anastomosing maze of high-energy rapids in Brazil: the Lower Xingu River Rapids (LXRR) and adjacent stretches of the Xingu. The LXRR faces imminent change from its wild state to both dewatered and lentic, impounded habitats following completion of the Belo Monte hydroelectric dam. New comprehensive specimen collections of fishes, crustaceans and mollusks and associated data will be used to address key questions in taxonomy, evolution and ecology, and will provide a permanent record (placed at US and Brazilian museums) and environmental baseline of life within the LXRR to assess future anthropogenic impacts.This project will advance understanding of the contribution that large river rapids make to tropical biodiversity and productivity, and will train a wide range aquatic scientists needed for the future study, protection and restoration of these habitats. An on-line, publicly accessible illustrated guide to the identification of LXRR fishes and invertebrates will be created. Two postdoctoral scientists will be supported. Training and learning opportunities will be offered for high school, undergraduate and graduate students.

亚马逊盆地是地球上生物多样性最丰富的分水岭，但物种多样性、种群结构、生物地理范围以及生态和进化过程仍有许多未知之处。该项目将记录和分析巴西130公里长的高能急流错综复杂的水生生物多样性：新谷河下游急流(LXRR)和邻近的新谷河段。随着贝洛蒙特水电站大坝的建成，LXRR面临着即将从野生状态转变为脱水和狭小的蓄水栖息地的问题。新的全面的鱼类、甲壳类和软体动物标本收藏和相关数据将用于解决分类学、进化和生态学中的关键问题，并将提供LXRR内生命的永久记录(放置在美国和巴西博物馆)和环境基线，以评估未来的人为影响。该项目将促进对大型河流急流对热带生物多样性和生产力的贡献的了解，并将培训未来研究、保护和恢复这些栖息地所需的广泛的水生科学家。将创建一个在线的、可供公众访问的图解指南，以识别LXRR鱼类和无脊椎动物。两名博士后科学家将得到支持。将为高中生、本科生和研究生提供培训和学习机会。
