气候变化正在改变决定相互作用物种物候的环境因素。如果蜜蜂和开花植物对气温升高的物候反应不同，植物-传粉系统可能容易受到时间不匹配的影响。虽然引发开花的线索已广为人知，但对于决定蜜蜂物候的因素却知之甚少。使用广义相加模型，我们分析了 9 年来在科罗拉多州落基山脉收集的代表 67 种蜜蜂的时间序列数据，以对蜜蜂物候驱动因素进行首次全社区量化。蜜蜂的出现对气候变化敏感，随着融雪时间的提前而提前，而较晚的物候期最好由越冬阶段和巢穴位置等功能特征来解释。将这些发现与长期花卉研究进行比较表明，蜜蜂物候学对气候变化的敏感度低于花卉物候学，这表明气候变化下花卉和传粉媒介的同步性可能会降低。
Climate change is shifting the environmental cues that determine the phenology of interacting species. Plant–pollinator systems may be susceptible to temporal mismatch if bees and flowering plants differ in their phenological responses to warming temperatures. While the cues that trigger flowering are well‐understood, little is known about what determines bee phenology. Using generalised additive models, we analyzed time‐series data representing 67 bee species collected over 9 years in the Colorado Rocky Mountains to perform the first community‐wide quantification of the drivers of bee phenology. Bee emergence was sensitive to climatic variation, advancing with earlier snowmelt timing, whereas later phenophases were best explained by functional traits including overwintering stage and nest location. Comparison of these findings to a long‐term flower study showed that bee phenology is less sensitive than flower phenology to climatic variation, indicating potential for reduced synchrony of flowers and pollinators under climate change.
