Resumo:[EN] We analyze the effects of the Three Gorges Dam (upper reaches of Yangtze River, Central China) on biodiversity. The dam will harbor the largest hydropower plant in the world, and will flood a 600 km2 area. It will result in the loss and/or fragmentation of many terrestrial habitats (including plants and animals) in a region that played a significant role as a glacial refuge, and currently harbors many endemic and threatened taxa. Negative effects on downstream biodiversity are also expected, because of the regression of the riparian wetlands and lateral lakes. Many plant and animal populations (and probably entire species) may be lost if conservation measures are not properly implemented, Alteration of the river flow will exert severe consequences on freshwater biodiversity, especially on migratory fishes such as two endangered sturgeons and one paddlefish, and the emblematic Yangtze River dolphin. Spillage of toxic substances into the river constitutes an additional threat.
