The vast boreal biome plays an important role in the global carbon cycle but is experiencing particularly rapid climate warming, threatening the integrity of valued ecosystems and their component species. We developed a framework and taxonomy to identify climate‐change refugia potential in the North American boreal region, summarizing current knowledge regarding mechanisms, geographic distribution, and landscape indicators. While “terrain‐mediated” refugia will mostly be limited to coastal and mountain regions, the ecological inertia (resistance to external fluctuations) contained in some boreal ecosystems may provide more extensive buffering against climate change, resulting in “ecosystem‐protected” refugia. A notable example is boreal peatlands, which can retain high surface soil moisture and water tables even in the face of drought. Refugia from wildfire are also especially important in the boreal region, which is characterized by active disturbance regimes. Our framework will help identify areas of high refugia potential, and inform ecosystem management and conservation planning in light of climate change.

北美北部的气候变化避难所:什么,在哪里以及持续多长时间?

巨大的北方生物群落在全球碳循环中起着重要作用,但正经历着特别迅速的气候变暖,威胁到有价值的生态系统及其组成物种的完整性。我们总结了有关机制,地理分布和景观指标的最新知识,从而开发了框架和分类法来确定北美北方地区的气候变化避难所潜力。尽管“地形介导”避难所主要限于沿海和山区,但某些北方生态系统中所包含的生态惯性(对外部波动的抵抗力)可能提供更广泛的缓冲以应对气候变化,从而导致“生态系统保护”避难所。北方泥炭地是一个著名的例子,即使面对干旱,它也可以保持较高的表层土壤湿度和地下水位。野火的避难所在以主动干扰机制为特征的北方地区也特别重要。我们的框架将帮助确定潜在的避难所,并根据气候变化为生态系统管理和保护规划提供依据。
