Roxanne Banker is a postdoctoral researcher at the University of Nevada Las Vegas working with Dr. Carrie Tyler. She is broadly interested in how ecological interactions at multiple scales of biological organization affect organismal and community responses to climate change in modern and ancient ecosystems. For her seminar, she will focus on her recent postdoctoral work reconstructing food web networks and examining community structure from fossil communities spanning the Mesozoic Marine Revolution, a period of time ~250 to 65 Million years ago (Ma) during which marine communities experienced marked increases in functional diversity and primary productivity..
