生活史特征是影响生长、生存和繁殖的身体特征或行为，在生物体如何应对环境变化方面可发挥重要作用。通过在群体中寻找基于特征的反应，我们可以从机制上理解为什么环境变化可能有利于或不利于某些物种。我们在落基山脉的亚高山地区连续8年监测了至少154种蜜蜂的丰度，以询问蜜蜂是否根据其生活史特征对非生物条件的变化做出不同的反应。我们发现，随着温度的升高，蜂巢建筑腔巢和较大的身体蜜蜂的相对丰度下降，而较小的，土壤筑巢蜜蜂增加。此外，蜜蜂与较窄的饮食宽度增加相对丰富的降雨量减少。最后，积雪减少与减少相对丰度的蜜蜂，越冬的prepuelium，而蜜蜂越冬的成年人增加相对丰度，这表明越冬条件可能会影响身体大小，脂质含量和越冬生存。总之，我们的研究结果表明，气候变化可能会重塑蜜蜂传粉者群落，具有某些特征的蜜蜂数量增加，其他特征减少，可能导致新的植物-传粉者相互作用和植物繁殖的变化。
Life-history traits, which are physical traits or behaviours that affect growth, survivorship and reproduction, could play an important role in how well organisms respond to environmental change. By looking for trait-based responses within groups, we can gain a mechanistic understanding of why environmental change might favour or penalize certain species over others. We monitored the abundance of at least 154 bee species for 8 consecutive years in a subalpine region of the Rocky Mountains to ask whether bees respond differently to changes in abiotic conditions based on their life-history traits. We found that comb-building cavity nesters and larger bodied bees declined in relative abundance with increasing temperatures, while smaller, soil-nesting bees increased. Further, bees with narrower diet breadths increased in relative abundance with decreased rainfall. Finally, reduced snowpack was associated with reduced relative abundance of bees that overwintered as prepupae whereas bees that overwintered as adults increased in relative abundance, suggesting that overwintering conditions might affect body size, lipid content and overwintering survival. Taken together, our results show how climate change may reshape bee pollinator communities, with bees with certain traits increasing in abundance and others declining, potentially leading to novel plant–pollinator interactions and changes in plant reproduction.
