More than 60% of earth’s terrestrial surface is managed by humans as agriculture, pasture, or urbanized areas, and land conversion continues to be the primary driver of global biodiversity loss. Despite this, little is known about the impacts of land management on multi-species interactions, gene flow, and ecosystem function. The Jha Lab investigates ecological and evolutionary processes from genes to landscapes, to quantify global change impacts on plant-animal interactions, movement ecology, and the provisioning of ecosystem services. Specifically, our work has provided insight into the environmental drivers of pollinator diversity, has revealed the complex and dynamic nature of wild pollinator foraging, and has exposed critical urbanization and elevation barriers to plant and pollinator gene flow across historic and contemporary time scales.
