Alex Pane

PhD Student


Alex is a PhD student at the University of Washington, co-advised by Dr. Carroll and Dr. Patrick Tobin. Insects are strongly affected by climate and changes in climate because many of their physiological processes are regulated by temperature. Consequently, warming temperatures have critical ramifications to insect populations, including more frequent and/or more intense outbreaks. Using historical aerial detection survey data (1960-2018) from Oregon, Washington, and British Columbia, Alex is attempting to quantify how the spatial and temporal dynamics of bark beetles, defoliators, and their interactions at local and regional scales have changed through time. He is also measuring how natural enemy communities influence the dynamics of two native forest insect species in Washington, Douglas-fir beetle and western spruce budworm, both of which have a propensity for outbreaks east of the Cascade Mountain Range, but not west.
