Plant-pollinator interactions and ecosystem services in the face of global change

More than 80% of all flowering plant species benefit from pollination services, including the majority of global crop species, and much of these services are mediated by native bees; despite this fact, we are only beginning to understand how global change forces interact to impact native bee communities, population structure, and foraging dynamics. In this talk, I will evaluate ecological and evolutionary processes from genes to landscapes to quantify the impact of local, landscape, and regional habitat composition on native bee community structure, dispersal and foraging dynamics, and the provisioning of pollination services. Specifically, we will discuss drivers of pollinator diversity, the complex nature of wild bee foraging, the and the impacts of deforestation, urbanization, and climate change on pollen-mediated gene flow, as well as implication for wild and cultivated plant reproduction.
