Mutualisms across agricultural landscapes

Mutualists, such as bees for pollination and arbuscular mycorrhizal fungi (AMF) for plant access to limiting nutrients, are critically important for agriculture. The predictability of species diversity and turnover of these mutualists across agricultural landscapes is crucial to ecosystem functions. Importantly, the ecology of mutualists depends on their interactions with plant hosts, including the degree of specificity of their relationships with host plants. My work examines the assembly of mutualists (belowground and aboveground), across agricultural landscapes, where human modification of plant communities and the soil environment could influence mutualistic niches.
