Data from: Climate change impacts on bumblebees converge across continents

For many species, geographical ranges are expanding toward the poles in
response to climate change, while remaining stable along range edges
nearest the equator. Using long-term observations across Europe and North
America over 110 years, we tested for climate change–related range shifts
in bumblebee species across the full extents of their latitudinal and
thermal limits and movements along elevation gradients. We found
cross-continentally consistent trends in failures to track warming through
time at species’ northern range limits, range losses from southern range
limits, and shifts to higher elevations among southern species. These
effects are independent of changing land uses or pesticide applications
and underscore the need to test for climate impacts at both leading and
trailing latitudinal and thermal limits for species.

对于许多物种而言，其地理分布范围（geographical ranges）正随气候变化向两极扩张，而在靠近赤道的分布边缘则保持稳定。通过对欧洲和北美地区110年间的长期观测，我们针对大黄蜂（bumblebee）物种在其纬度极限（latitudinal limits）与热耐受极限（thermal limits）全范围内的气候变化相关分布范围迁移，以及沿海拔梯度（elevation gradients）的移动进行了检验。我们发现了跨大陆一致的趋势：物种在其北部分布极限处未能随时间推移追踪气候变暖，南部分布极限处出现分布范围丧失，且南部物种向更高海拔迁移。这些效应与土地利用变化（changing land uses）或农药施用（pesticide applications）无关，强调了需在物种的前沿与后缘纬度及热耐受极限处检验气候变化影响的必要性。
