项目摘要

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.

亚马逊盆地是地球吗？它是世界上最具生物多样性的流域，但关于物种多样性、种群结构、地理分布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一个130公里长的高能量急流迷宫的水生生物多样性：下辛古河急流（LXRR）和辛古河的邻近河段。在贝洛蒙特水电站大坝建成后，LXRR面临着即将从野生状态转变为脱水和缓慢的蓄水栖息地的变化。新的全面的鱼类、甲壳类和软体动物标本收集和相关数据将用于解决分类学、进化和生态学方面的关键问题，并将提供永久记录（放置在美国和巴西博物馆）和LXRR内的生命环境基线，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理解，并将为这些栖息地的未来研究，保护和恢复培养广泛的水生科学家。将创建一个在线的、公众可访问的LXRR鱼类和无脊椎动物识别图解指南。将资助两名博士后科学家。将为高中、本科和研究生提供培训和学习机会。
