了解过去和现在气候变化对生物多样性的影响对于有效保护生物多样性至关重要。两栖动物的扩散能力很弱，使它们面临栖息地碎片化和丧失的风险。气候变化和人为干扰都加剧了这些风险，增加了在不久的将来发生更多两栖动物灭绝的可能性。巨型刺蛙(Quasipaa Spinosa)是东亚特有的物种，在过去的几十年里面临着种群数量的急剧下降。以巨大的棘蛙为指标，探索过去和未来的气候变化如何影响景观连通性，我们表征了青蛙适宜栖息地和栖息地连通性的变化。我们发现，在最后一次冰川盛期，巨型棘蛙的适宜栖息地明显向北移动，适宜栖息地的范围有所减少；从那时起，可用的栖息地一直在扩大。我们的模型显示，“过热”的气候条件很可能会导致可用栖息地的减少和未来种群碎片化程度的增加。我们发现，在未来的气候变化下，被研究的青蛙的栖息地连通性将下降50%-75%。我们的结果强化了这样的观点，即中国南部的山脉和中越跨境地区可以作为未来保护规划的关键避难所和优先地区。鉴于两栖动物对环境变化高度敏感，我们的研究结果突出表明，栖息地适宜性和连通性对气候变化的反应可能是未来保护扩散能力较弱物种的关键考虑因素，不应被忽视，因为它们经常被忽视。网上版载有补充材料，可在10.1186/s12983-021-00398-w查阅。
Understanding the impacts of past and contemporary climate change on biodiversity is critical for effective conservation. Amphibians have weak dispersal abilities, putting them at risk of habitat fragmentation and loss. Both climate change and anthropogenic disturbances exacerbate these risks, increasing the likelihood of additional amphibian extinctions in the near future. The giant spiny frog (Quasipaa spinosa), an endemic species to East Asia, has faced a dramatic population decline over the last few decades. Using the giant spiny frog as an indicator to explore how past and future climate changes affect landscape connectivity, we characterized the shifts in the suitable habitat and habitat connectivity of the frog. We found a clear northward shift and a reduction in the extent of suitable habitat during the Last Glacial Maximum for giant spiny frogs; since that time, there has been an expansion of the available habitat. Our modelling showed that “overwarm” climatic conditions would most likely cause a decrease in the available habitat and an increase in the magnitude of population fragmentation in the future. We found that the habitat connectivity of the studied frogs will decrease by 50–75% under future climate change. Our results strengthen the notion that the mountains in southern China and the Sino-Vietnamese transboundary regions can act as critical refugia and priority areas of conservation planning going forward. Given that amphibians are highly sensitive to environmental changes, our findings highlight that the responses of habitat suitability and connectivity to climate change can be critical considerations in future conservation measures for species with weak dispersal abilities and should not be neglected, as they all too often are.
