制定全球保护优先事项的努力在很大程度上忽视了淡水多样性，从而排除了一些世界上最奇特、受威胁和有价值的类群。利用新的全球淡水生态区地图和约 13,300 种鱼类的分布数据，我们确定了具有特殊淡水生物多样性的区域，并评估了它们与具有同等陆地重要性的区域的重叠。重叠在热带地区最大，并且高于偶然的预期。这些高度一致性的区域为综合保护工作提供了机会，当经济条件迫使保护组织缩小关注范围时，这可能具有特别的价值。当前陆地优先计划所忽略的低重叠区域值得独立的淡水保护工作。这些结果为保护投资者在全球或区域范围内设定优先事项提供了新信息，并主张未来资源的潜在重新分配，以实现被忽视的生物群落的代表性。
Efforts to set global conservation priorities have largely ignored freshwater diversity, thereby excluding some of the world's most speciose, threatened, and valuable taxa. Using a new global map of freshwater ecoregions and distribution data for about 13,300 fish species, we identify regions of exceptional freshwater biodiversity and assess their overlap with regions of equivalent terrestrial importance. Overlap is greatest in the tropics and is higher than expected by chance. These high-congruence areas offer opportunities for integrated conservation efforts, which could be of particular value when economic conditions force conservation organizations to narrow their focus. Areas of low overlap-missed by current terrestrially based priority schemes-merit independent freshwater conservation efforts. These results provide new information to conservation investors setting priorities at global or regional scales and argue for a potential reallocation of future resources to achieve representation of overlooked biomes.
