Marcus Drymon, right, MSU associate Extension professor in marine fisheries ecology, examines a shark for tags off the coast of Dauphin Island, Alabama. Drymon and Lindsay Mullins, a university Ph.D. student in marine science, have a news article in The Conversation this week based on a research study on the abundance of baby bull sharks in Alabama and Texas bays. The increase, according to the study, is explained by slight increases in temperature over the past two decades in the Gulf of Mexico. Drymon’s research has also landed him in a new National Geographic documentary “Shark Beach with Anthony Mackie” on Disney+.
