Dragonflies are sensitive to climate change due to their special habitat in aquatic and terrestrial environments, especially , which have extraordinary migratory abilities in response to climate change on spatio-temporal scales. At present, there are major gaps in the documentation of insects and the effects of climatic changes on the habitat and species it supports. In this study, we model the global distribution of a wandering glider dragonfly, , and detected the important environmental factors shaping its range, as well as habitat shifts under historical and future warming scenarios. The results showed a global map of species ranges of currently, including southern North America, most of South America, south-central Africa, most of Europe, South, East and Southeast Asia, and northern Oceania, in total, ca. 6581.667 × 10 km. BIO5 (the max temperature of warmest month) and BIO13 (the precipitation of wettest month) greatly explained its species ranges. The historic refugia were identified around the Great Lakes in the north-central United States. Future warming will increase the total area of suitable habitat and shift the type of suitable habitat compared to the current distribution. The habitat suitability of decreased with elevation, global warming forced it to expand to higher elevations, and the habitat suitability of around the equator increased with global warming. Overall, our study provides a global dynamic pattern of suitable habitats for from the perspective of climate change, and provides a useful reference for biodiversity research and biological conservation.
由于蜻蜓在水生和陆地环境中的特殊栖息地，它们对气候变化很敏感，尤其是那些在时空尺度上对气候变化具有非凡迁徙能力的蜻蜓。目前，昆虫记录以及气候变化对其栖息地和所支持物种的影响方面存在重大空白。在本研究中，我们对一种长尾黄蜻的全球分布进行建模，并检测了塑造其分布范围的重要环境因素，以及历史和未来变暖情景下的栖息地变化。结果显示了目前长尾黄蜻的全球分布图，包括北美南部、南美洲大部分地区、非洲中南部、欧洲大部分地区、南亚、东亚和东南亚以及大洋洲北部，总面积约为6581.667×10平方千米。生物气候变量5（最暖月最高温度）和生物气候变量13（最湿月降水量）极大地解释了其物种分布范围。历史避难所位于美国中北部的五大湖周围。与当前分布相比，未来变暖将增加适宜栖息地的总面积，并改变适宜栖息地的类型。长尾黄蜻的栖息地适宜性随海拔升高而降低，全球变暖迫使它向更高海拔扩展，而赤道附近长尾黄蜻的栖息地适宜性则随全球变暖而增加。总体而言，我们的研究从气候变化的角度提供了长尾黄蜻适宜栖息地的全球动态模式，为生物多样性研究和生物保护提供了有用的参考。
