All the world's an oven: How rapidly warming temperatures are impacting bumble bee communities and the pollination services they provide

A rapidly warming climate is a primary force driving changes in biodiversity worldwide, and its impact on insect communities is of particular interest given their outsized role in ecosystem function and services, such as pollination. Here, we will share ongoing, cross-scale research bridging the impact extreme heat on bumble bees from behavior to continental-scale patterns of community composition. We show that extreme heat has the potential to fundamentally alter bumble bee pollination services, and that bumble bee communities are rapidly being restructured as summer maximum temperatures have increased over the past 30 years. Our results ultimately show the pervasive impacts and ecological implications warming temperatures pose to this critical and charismatic taxa.
