Genetic diversity in frogs linked to past and future climate change on the roof of the world

Mountains, representing storehouses of biodiversity, endemism, and threatened species, are biodiversity hotspots of great conservation importance. However, increasing evidence indicates that mountain species throughout the world are responding to climate change, past or contemporary, by shifting their geographic distributions and patterns of genetic diversity, potentially affecting their adaptive capacity and increasing risk of extinction. Using the iconic high‐elevation frog Nanorana parkeri as indicator, we showed how spatial analyses of climatic stability combined with genetic data allow unravelling amphibian responses to past and future climate changes on ‘the roof of the world’—the Qinghai‐Tibetan Plateau. We found that areas along the Yarlung Tsangpo Valley were climatically more stable relative to other regions, apparently serving as a large climatic refugium during Quaternary glaciations, but that these areas will likely be affected by future climate change. As populations...山地作为生物多样性、特有物种与受胁物种的储存库，是具有极高保护价值的生物多样性热点（biodiversity hotspot）区域。然而，日益增多的研究证据显示，全球山地物种正针对历史及当代气候变化调整其地理分布范围与遗传多样性格局，这可能削弱其适应能力并加剧灭绝风险。 本研究以标志性高海拔两栖类物种高山倭蛙（Nanorana parkeri）作为指示类群，阐明了如何通过气候稳定性空间分析结合遗传数据，解析"世界屋脊"——青藏高原（Qinghai-Tibetan Plateau）上两栖类对历史及未来气候变化的响应机制。 研究发现，雅鲁藏布江谷地（Yarlung Tsangpo Valley）相较于其他区域气候更为稳定，在第四纪冰期期间充当了大型气候避难所，但该区域未来仍可能受到气候变化的影响。后续种群……
