ABSTRACT
The increase in global food production has come at the cost of biodiversity loss and impaired ecosystem services. Managing agricultural expansion and intensification holds promise as means to decrease impact on the natural systems on which human wellbeing ultimately depends. Pollination is a critical ecosystem service for crop production that can be improved by conserving mobile organisms, including but not limited to bees. Pollination management requires a landscape perspective, yet to-date conservation efforts have been limited by a lack of information about the local and landscape factors that most directly influence the activity and biodiversity of pollinator communities. To address this information gap I will identify the spatial scale and landscape attributes most relevant to pollinator conservation. Farm-level decisions are important as well; building on current models, I will improve our ability to predict pollinator response to land management scenarios. Moreover, I propose to expand our understanding of the benefits of pollinators in agricultural landscapes by testing whether there are effects on adjacent native plant reproductive success. Finally, I will examine the differential response of pollinator communities to ordered and random extinctions in order to demonstrate the potential stabilizing effect of biodiversity for ecosystem services. The results will provide land managers with explicit information about the effects of landscape conservation for pollinators, as well as the forgone benefits that result from biodiversity loss.
