Thirteen marine biology and environmental studies students gave oral presentations of their research at the colloquium. Kristin Stover received the best oral presentation award for her talk “Performance changes when exposed to varying oxygen levels in the Atlantic blue crab, Callinectes sapidus Rathbun.” Additionally, seventeen students presented posters of their thesis research this year. Timothy O’Donnell received the best poster presentation award for his research “Characterizing the genetic population structure and genetic influences of winter-kill events in spotted seatrout (Cynoscion nebulosus) in South Carolina.” The colloquium concluded with a cookout and Lowcountry Boil for students, professors, and attendees at the SCDNR outdoor classroom.
