Elizabeth is broadly interested in the foraging ecology and in-water behavior of marine turtles. In Abaco, Bahamas, she studying the top-down and bottom-up factors that may affect green turtle (Chelonia mydas) distributions through surveys of habitat, food availability, predators (sharks) and green turtle densities. She is also studying the top-down effects of green turtle grazing in seagrass communities using a multi-year megagrazer exclosure experiment. In the French Antilles (Guadeloupe, Martinique and St. Martin) she is expanding this work to investigate the role that green turtles may play in the spread of the invasive seagrass Halophila stipulate. She works closely with nonprofit organizations such as Friends of the Environment on Abaco to share scientific knowledge with local communities and inspire future generations.
