Climate change and biological invasions are affecting natural ecosystems globally. The effects of these stressors on native species' biogeography have been studied separately, but their combined effects remain overlooked. Here, we develop a framework to assess how climate change influences both the range and niche overlap of native and non‐native species using ecological niche models. We hypothesize that species with similar niches will experience both range reductions and increased niche overlap under future climates. We evaluate this using the ongoing invasion of smallmouth bass (Micropterus dolomieu ) and northern pike (Esox lucius ) on the native habitats of redband trout (Oncorhynchus mykiss ) and bull trout (Salvelinus confluentus ) in western North America. Future climate conditions will reduce habitat suitability for native and non‐native species, but an increased niche overlap might exacerbate negative effects on native fishes. Our framework offers a tool to predict potential species distribution and interactions under climate change, informing adaptive management globally.

气候变化下本地物种的双重困境:栖息地丧失和与非本地物种的环境重叠增加
气候变化和生物入侵正在影响全球的自然生态系统。这些压力源对本地物种生物地理学的影响已经单独研究,但它们的综合影响仍然被忽视。在这里,我们开发了一个框架,使用生态位模型来评估气候变化如何影响本地和非本地物种的范围和生态位重叠。我们假设在未来气候下,具有相似生态位的物种将经历范围缩小和生态位重叠增加。我们使用小口黑鲈 (Micropterus dolomieu) 和北梭子鱼 (Esox lucius) 对北美西部红带鳟鱼 (Oncorhynchus mykiss) 和牛鳟鱼 (Salvelinus confluentus) 原生栖息地的持续入侵来评估这一点。未来的气候条件将降低本地和非本地物种的栖息地适宜性,但生态位重叠的增加可能会加剧对本地鱼类的负面影响。我们的框架提供了一种工具,可以预测气候变化下潜在的物种分布和相互作用,为全球适应性管理提供信息。
