It is clear that ecosystems are devastated after a volcanic eruption coats the landscape with a layer of ash; however, the ecological recovery of mammalian communities after eruptions is poorly understood. Volcanic eruptions vary with magnitude and type and only a fraction of them have been analyzed for effects on mammalian communities. In this talk we will explore how mammalian species change across volcanic boundaries by looking at three volcanic eruptions: the 1980 Mount St. Helens eruption sheds light on short term recovery after a moderate sized eruption; the 1914-1917 Mount Lassen eruption permits an analysis of long-term impacts from a relatively small eruption; and the Picture Gorge Ignimbrite (28.7 Ma) within the Turtle Cove Member of the John Day Formation was a supervolcanic eruption associated with the Yellowstone hotspot.
