Mollusk expert to present on biodiversity Friday Arthur Bogan of the North Carolina State Museum of Natural History, Raleigh, will present the geology and geological engineering LEEPS lectures at noon and 3 p.m. Friday, Jan. 19. Dr. Bogan’s talks are titled: “Global Freshwater Bivalve Diversity and Extinction” and “Freshwater Bivalve Diversity and Convergence: How Do We Interpret the Fossil Record?” Dr. Bogan is the curator of aquatic invertebrates at the North Carolina State Museum of Natural History, and is one of the world’s preeminent freshwater molluscan experts. His global travels and major research volumes have given him a first-hand basis to interpret these critters both in the field using morphology and in the lab using genetics. LEEPS (Leading Edge of Earth and Planetary Science) lectures are sponsored by geology and geological engineering alumni and the office of the vice president for research for the educational development of our students, faculty, and others wishing to attend.
