However, little is known about the relative importance of direct and indirect effects, particularly for species important to ecosystem functioning, like pollinators. We used structural equation modelling to test the importance of direct and indirect (via floral resources) climate effects on the interannual abundance of three subalpine bumble bee species. In addition, we used long-term data to examine how climate and floral resources have changed over time. Over 8 years, bee abundances were driven primarily by the indirect effects of climate on the temporal distribution of floral resources. Over 43 years, aspects of floral phenology changed in ways that indicate species-specific effects on bees. Our study suggests that climate-driven alterations in floral resource phenology can play a critical role in governing bee population responses to global change.}, number={12}, journal={Ecology Letters}, publisher={Wiley}, author={Ogilvie, Jane E. and Griffin, Sean R. and Gezon, Zachariah J. and Inouye, Brian D. and Underwood, Nora and Inouye, David W. and Irwin, Rebecca E.}, editor={Bourke, AndrewEditor}, year={2017}, month={Sep}, pages={1507–1515} }
