Conservation of climatic refugia, or locations that will buffer vulnerable species from the effects of climate change, has recently emerged as a prominent climate adaptation strategy. Here, we introduce an important and complementary concept, 'climatic nuclei'-locations that harbor populations of species that are expected to expand under future conditions-which has so far received little attention. While the climatic refugia concept focuses on threatened species, the climatic nuclei concept focuses on species that are projected to expand with climate change to help create the functional, diverse, and locally unique ecosystems of the future. We evaluate where climatic nuclei are expected to occur; draw on lessons from the paleoecological and modern ecological literature to better understand how climatic nuclei could function; explore the concept's application to land stewardship and conservation; and provide suggestions for future research.
保护气候避难所，即能保护易受影响物种免受气候变化影响的区域，最近已成为一项重要的气候适应策略。在此，我们引入一个重要且互补的概念——“气候核心区”，即那些拥有预计在未来条件下会扩张的物种种群的区域，然而到目前为止该概念几乎未受到关注。虽然气候避难所概念关注的是受威胁物种，但气候核心区概念关注的是预计会随气候变化而扩张的物种，以助力构建未来功能健全、多样且具有地方特色的生态系统。我们评估气候核心区可能出现的位置；借鉴古生态和现代生态文献中的经验教训，以更好地理解气候核心区如何发挥作用；探讨该概念在土地管理和保护中的应用；并为未来研究提供建议。
