Abstract Climate change is the defining environmental problem for our generation. The effects of climate change are increasingly evident and are anticipated to profoundly affect our ability to conserve fish habitats and fish assemblages. Reservoirs are important structures for coping with projected shifts in water supply, but they also provide refuge for riverine fishes and retain distinct fish assemblages that support diverse fisheries. The effects of climate change on reservoirs are unique among aquatic systems because reservoirs have distinctive habitat characteristics due to their terrestrial origin and strong linkage to catchments. This article reviews (1) the projected effects of rising temperature and shifting precipitation on reservoir fish habitats, and (2) adaptation strategies to cope with the anticipated effects. Climate warming impacts to reservoirs may include higher water temperatures and shifts in hydrology that can result in reduced water levels in summer and fall, altered water residence cycles, disconnection from upstream riverine habitats and backwaters, increased stratification, eutrophication, anoxia, and a general shift in biotic assemblages including plants, invertebrates, and fishes. What is needed to adapt to these changes is a perspective that focuses on maintaining ecosystem functionality rather than on retaining a certain species composition. To that end, various strategies organized into planning, monitoring, and managing compartments are identified.

水库鱼类栖息地：应对气候变化的视角

摘要 气候变化是我们这一代决定性的环境问题。气候变化的影响越来越明显，预计将深刻影响我们保护鱼类栖息地和鱼类群落的能力。水库是应对供水预计变化的重要结构，但它们也为河流鱼类提供避难所，并保留支持多样化渔业的独特鱼类组合。气候变化对水库的影响在水生系统中是独一无二的，因为水库因其陆地起源和与流域的紧密联系而具有独特的栖息地特征。本文回顾了 (1) 气温升高和降水变化对水库鱼类栖息地的预期影响，以及 (2) 应对预期影响的适应策略。气候变暖对水库的影响可能包括水温升高和水文变化，这可能导致夏季和秋季水位降低、水居住周期改变、与上游河流栖息地和回水断开、分层增加、富营养化、缺氧和普遍转变在包括植物、无脊椎动物和鱼类在内的生物组合中。适应这些变化所需要的是一种关注维持生态系统功能而不是保留特定物种组成的观点。为此，确定了组织成规划、监控和管理分区的各种策略。与上游河流栖息地和回水的分离、分层加剧、富营养化、缺氧以及包括植物、无脊椎动物和鱼类在内的生物组合的普遍转变。适应这些变化所需要的是关注维持生态系统功能而不是保留特定物种组成的观点。为此，确定了组织成规划、监控和管理分区的各种策略。与上游河流栖息地和回水的分离、分层加剧、富营养化、缺氧以及包括植物、无脊椎动物和鱼类在内的生物组合的普遍转变。适应这些变化所需要的是一种关注维持生态系统功能而不是保留特定物种组成的观点。为此，确定了组织成规划、监控和管理分区的各种策略。
