摘要：由于气候变化和入侵物种的相互作用，管理受保护物种的艰巨任务可能变得更具挑战性。除了对栖息地质量的直接影响外，气候变化还将促使入侵物种向新的地区扩张，并通过改变竞争优势，增加捕食率和增强疾病的毒性来放大已经存在的入侵物种的影响。在某些情况下，准热带物种可能会扩展到新的栖息地，并产生与入侵的非本地物种相似的有害影响。如果栖息地条件的变化超出了历史范围或有利于入侵物种，那么在保护区隔离濒危物种的传统策略可能是不够的。气候变化的后果将需要一个更积极的管理模式，包括实施栖息地改善，减少气候变化的影响，并建立迁移障碍，防止入侵物种的涌入。应考虑的其他管理行动包括提供扩散走廊，使物种能够跟踪环境变化，将物种转移到不可能迁移的新的合适栖息地，并制定行动计划，及早发现和消灭新的入侵物种。
Abstract: The difficult task of managing species of conservation concern is likely to become even more challenging due to the interaction of climate change and invasive species. In addition to direct effects on habitat quality, climate change will foster the expansion of invasive species into new areas and magnify the effects of invasive species already present by altering competitive dominance, increasing predation rates, and enhancing the virulence of diseases. In some cases parapatric species may expand into new habitats and have detrimental effects that are similar to those of invading non‐native species. The traditional strategy of isolating imperiled species in reserves may not be adequate if habitat conditions change beyond historic ranges or in ways that favor invasive species. The consequences of climate change will require a more active management paradigm that includes implementing habitat improvements that reduce the effects of climate change and creating migration barriers that prevent an influx of invasive species. Other management actions that should be considered include providing dispersal corridors that allow species to track environmental changes, translocating species to newly suitable habitats where migration is not possible, and developing action plans for the early detection and eradication of new invasive species.
