Billy completed his Ph.D. in ecology at UC Davis with a focus on native plant-insect interactions, and now run a native landscaping company called Restoration Landscaping Company that integrates ecological restoration science into urban landscaping. Billy offers: "In plant-herbivore-omnivore interactions and how plant traits affect, and are affected by, resident arthropods. My strategy for studying these interactions is to target systems with high specialization and strong herbivore-plant and predator-prey relationships. Most of the systems I work with involve glandular plants because the arthropod community on these plants is highly specialized and omnivory is very common. Currently I am working with two main systems in CA. Each one provides unique insights into the complex interactions between plants, herbivores and omnivores. I find that by studying systems with specialization, evolutionary history and strong trophic links, interactions that may not be obvious in novel or agricultural systems can be conspicuous, amenable to study, and relatively straightforward to interpret into an adaptive framework."
