Large-scale conservation of biodiversity requires understanding how species are distributed around the world. The first global delineation of freshwater ecoregions (Abell et al. 2008) integrated hydrological boundaries and fish biogeographic patterns to recognize 426 distinctive zones. Here, we update and expand that ecoregional approach to encompass every described freshwater-dependent vertebrate species: 23,130 species of fishes, birds, amphibians, reptiles, and mammals. Our database of freshwater vertebrates at the ecoregional scale (FreshVerts v1.0) includes a total of 96,129 ecoregional population records (average of 4.15 records per species, SD = 11.25) based on biogeographic databases and extensive bibliographic searches. This global attribution of all freshwater vertebrates to ecoregions provides a resource for analyzing global biodiversity, comparing biogeographic patterns among vertebrate taxa, and prioritizing efforts to conserve aquatic species across a variety of spatial scales.
大规模的生物多样性保护需要了解物种在全球的分布情况。淡水生态区域的首次全球划分（阿贝尔等人，2008年）整合了水文边界和鱼类生物地理模式，识别出426个独特区域。在此，我们更新并扩展了这种生态区域方法，将每一种已描述的依赖淡水的脊椎动物物种都纳入其中：23130种鱼类、鸟类、两栖动物、爬行动物和哺乳动物。我们在生态区域尺度上的淡水脊椎动物数据库（FreshVerts v1.0）基于生物地理数据库和广泛的文献检索，总共包含96129条生态区域种群记录（平均每个物种4.15条记录，标准差=11.25）。将所有淡水脊椎动物全球归属于各个生态区域，为分析全球生物多样性、比较脊椎动物类群之间的生物地理模式以及在各种空间尺度上优先开展保护水生物种的工作提供了一种资源。
