整个更新世的气候变化强烈地改变了物种的分布。我们研究了这些范围的变化如何影响山地蝴蝶物种的遗传多样性，以及现存种群的遗传多样性是否会受到未来气候变化的威胁。欧洲 凤蝶目：蛱蝶科。本研究通过对线粒体DNA的分析，对E. epiphron在欧洲各地，以确定人口避难所和冰后期范围的变化。我们使用物种分布模型（SDM）来追溯过去21，000年的分布，以确定现存种群的来源位置，并预测未来（2070年）的分布，以预测遗传多样性的潜在损失。我们发现大量的遗传多样性独特的特定区域内的欧洲（单倍型总数= 31，独特的单倍型数= 27，H d = 0.9）。遗传数据和SDM后报表明离散种群的长期分离和存活。特别是，独特的多样性在postglacially殖民地在英格兰（H D = 0.64）的高利率表明，这个人口是从现在灭绝的神秘避难所殖民。在未来气候变化的情况下，SDMs预测了E.因此，在2070年全球气温分别上升1°C和2-3°C的气候情景下，特别是在低海拔地区（海拔<1,000米），相当于1至12个独特的单倍型处于危险之中。我们的研究结果表明，历史范围的扩大和收缩过程中的冷适应的山区物种引起种群之间的多样化，导致独特的遗传多样性，这可能是在风险中，如果分布的冷适应物种在未来缩小。将处于危险中的种群中的个体协助殖民到气候适宜的无人居住的栖息地可能有助于保护独特的遗传多样性，而迁移到剩余种群中可能会增加它们的遗传多样性，从而提高它们适应未来气候变化的能力。冷适应山地物种的遗传多样性，如E。epiphron，已经形成了更新世冰川，导致独特的遗传多样性在孤立的人群。在未来气候变暖的情况下，山地和冷适应物种的独特遗传多样性将处于下降趋势，我们预测E。在未来，epiphron将失去38%-64%的活动范围，导致遗传多样性的丧失，降低其适应能力。
Climatic changes throughout the Pleistocene have strongly modified species distributions. We examine how these range shifts have affected the genetic diversity of a montane butterfly species and whether the genetic diversity in the extant populations is threatened by future climate change. Europe. Erebia epiphron Lepidoptera: Nymphalidae. We analyzed mtDNA to map current genetic diversity and differentiation of E. epiphron across Europe to identify population refugia and postglacial range shifts. We used species distribution modeling (SDM) to hindcast distributions over the last 21,000 years to identify source locations of extant populations and to project distributions into the future (2070) to predict potential losses in genetic diversity. We found substantial genetic diversity unique to specific regions within Europe (total number of haplotypes = 31, number of unique haplotypes = 27, H d = 0.9). Genetic data and SDM hindcasting suggest long‐term separation and survival of discrete populations. Particularly, high rates of unique diversity in postglacially colonized sites in England (H d = 0.64) suggest this population was colonized from a now extinct cryptic refugium. Under future climate change, SDMs predict loss of climate suitability for E. epiphron, particularly at lower elevations (<1,000 meters above sea level) equating to 1 to 12 unique haplotypes being at risk under climate scenarios projecting 1°C and 2–3°C increases respectfully in global temperature by 2070. Our results suggest that historical range expansion and retraction processes by a cold‐adapted mountain species caused diversification between populations, resulting in unique genetic diversity which may be at risk if distributions of cold‐adapted species shrink in future. Assisted colonizations of individuals from at‐risk populations into climatically suitable unoccupied habitat might help conserve unique genetic diversity, and translocations into remaining populations might increase their genetic diversity and hence their ability to adapt to future climate change. The genetic diversification of cold‐adapted mountain species, such as E. epiphron, has been shaped by Pleistocene glaciations, resulting in unique genetic diversity in isolated populations. The unique genetic diversity in mountain and cold‐adapted species is at under future climate warming, and we predict E. epiphron will lose 38%–64% of its range in the future, resulting in the loss of genetic diversity, reducing its ability to adapt.
