Lila Westreich

Lila is a Ph.D. candidate studying pollinator ecology, specifically the foraging behavior of native bees across a variety of flowering landscapes in western Washington and the impact of forage patterns on native bee health and fitness. Native bees search among angiosperms to find the most nutritionally sufficient food sources for their offspring, and the patterns of foraging behavior and their impact on development are not well understood. Along with pollen, bees collect microorganisms such as bacteria on the surface of flowers, which are transported back to the nest and are thought to play a role in the development of offspring. Lila is working to identify pollen and microorganisms collected from native mason bees using Next-Generation Sequencing, a novel genetic analysis technology in the study of native bees. Bee pollinators, especially native species, are increasingly important as other pollinator species are shown to be in decline. Prior to coming to the UW, Lila earned a B.S. in plant breeding and genetics from the University of Minnesota. Click here to learn more about Lila's research.

Alex Pane

Alex is a Ph.D. student who earned a B.S. in Integrative Biology from the University of Illinois, researching the nesting ecology of ground dwelling bees. With a taste for field research and a love for the outdoors, Alex moved west to pursue graduate work in the School of Environmental and Forest Sciences. In his time climbing and hiking, Alex has always come back to the same broad question: why do insect disturbances occur in some locations but not others? The iconic forests of the Pacific Northwest have been the perfect system to begin exploring this question, with insect disturbances occurring over highly variable spatial and temporal scales. His research focuses on identifying how native forest insect disturbances have changed in recent decades across the Pacific Northwest. Using long term regional data sets and intensive field sampling, Alex hopes to provide a better understanding of the processes driving these outbreak patterns and how they may shift as the climate continues to change.

Autumn Maust

Autumn is a M.S. student who received her B.S. in Natural Resources from the University of Vermont in 2018. As an undergraduate, she had the privilege to participate in conservation projects in New England and New Zealand. Prior to entering graduate school, she worked as an outdoor educator and encouraged students to engage in environmental stewardship while gardening, beekeeping, and exploring. Broadly, her research interests include entomophily, insect ecology, native landscape restoration, and disturbance ecology. Autumnís research project will discuss the effect of disturbance on established forest pollinator populations.
