Dr. Kelsey Arkle is an Assistant Professor in the Geology Department at Augustana College in Rock Island, Illinois. She received her B.A. in Geology from Cornell College in Mount Vernon, Illinois, and her Ph.D. in Geology, with a focus on Conservation Paleobiology/Paleoecology, from the University of Cincinnati.
Her research focus is using molluscan subfossil remains from shallow marine seagrass environments around St. Croix, in the United States Virgin Islands, to track changes in populations and substrates through time and space. She uses assemblages of living mollusks and assemblages of their accumulated empty to investigate temporal and spatial changes in these environments. By examining compositional changes (e.g. changes in taxa and their abundances), she addresses topics such as changes in this environment over centuries and millennia, variation in assemblages between samples or between localities, and the degree to which sediments in seagrass beds are mixed.
