Arctic regions are experiencing climate change impacts at disproportionately high rates. Rising temperatures, flooding from melting sea ice and increasing storm surges, and changing animal migration patterns are all contributing to altered Arctic ecosystems. Here, we examine the impact of warming, flooding, and increased herbivory on three plant communities, with varying levels of background inundation due to their distance from rivers, in the Yukon-Kuskokwim (Y-K) delta, a large riverine delta in Alaska. While previous research has examined climate change responses in the Arctic, there have been few studies on the response of plant functional traits to herbivory with other environmental factors. We will conduct an experiment to measure the impact of these variables (herbivory, flooding, and warming) across three different habitat types. My research will investigate the response of plant functional traits to the experimental treatments. I will fit linear mixed effects models to analyze the impact of our three treatments. This study will increase knowledge on climate change impacts on different plant communities across the Y-K Delta.
