The fossil record tells us that many species shifted their geographic distributions during historic climate changes, but this record does not portray the complete picture of future range change in response to climate change. In particular, it does not provide information on how species interactions will affect range shifts. Therefore, we also need modern research to generate understanding of range change. This paper focuses on the role that species interactions play in promoting or preventing geographic ranges shifts under current and future climate change, and we illustrate key points using empirical case studies from an integrated study system. Case studies can have limited generalizability, but they are critical to defining possible outcomes under climate change. Our case studies emphasize host limitation that could reduce range shifts and enemy release that could facilitate range expansion. We also need improvements in modeling that explicitly consider species interactions, and this modeling can be informed by empirical research. Finally, we discuss how species interactions have implications for range management by people.
化石记录告诉我们，许多物种在历史气候变化期间改变了它们的地理分布，但这一记录并不能描绘出物种对气候变化的未来反应的完整范围变化图景。特别是，它没有提供关于物种相互作用将如何影响范围转移的信息。因此，我们还需要现代研究来了解范围变化。本文重点关注物种相互作用在促进或阻止当前和未来气候变化下的地理范围转移方面所扮演的角色，并使用综合研究系统中的经验案例研究来说明要点。案例研究的普遍性可能有限，但它们对于确定气候变化下的可能结果至关重要。我们的案例研究强调了可能会减少范围转移的宿主限制，以及可能促进范围扩大的天敌释放。我们还需要改进明确考虑物种相互作用的模型，而这种模型可以通过实证研究来提供信息。最后，我们讨论了物种相互作用对人类的范围管理意味着什么。
