Project Title: Characterizing the structure and function of pollinator microbiomes

Project Description: The proposed work examines how increasing temperature and common microbial inhabitants of flowering plants influence nectar and pollen in flowers, the floral rewards that attract and sustain pollinators.  Our previous research suggests that rising temperatures accelerate microbial metabolism in nectar, exacerbating microbial effects on nectar and flower longevity.  This Fellowship will allow us to construct an experimental warming array and quantify the effects of temperature on floral resources of six species of California native plants.  Since pollinators depend on floral resources, this project will inform conservation efforts for pollinators under future climate scenarios.
