Climate change impacts on green wave in Yellowstone

For my postdoctoral work at UC Santa Cruz, I modeled the impacts of climate change on the dynamics of the wolf-elk-vegetation food web in the Northern Rockies. I used large datasets from satellite-derived vegetation indices, regional climate models, and weather stations to understand how different trophic levels respond to changing climate. My study is among a handful to explore how climate change (temperature, snow pack, and precipitation) drives the spatio-temporal dynamics of grassland phenology at the landscape scale. I am also investigating how variation in grass phenology affects migratory behavior of large herbivores such as elk.
