Dr. Dietmar Kueltz describes himself as “...a comparative biologist and most interested in mechanisms of stress-induced evolution. My lab studies how fish and marine invertebrates counteract environmental stress.” Originally from Berlin, Germany, he grew up interested in aquatic life. “I was diving and swimming a lot,” he said, “and I am interested in watersports and just about everything aquatic.” Dr. Kueltz attributes this early love of aquatics to his interest in studying stress and evolution in aquatic organisms.
“They are so green!” Dr. Katie DuBois exclaimed as I held the fluorescent green test tube in my hand. The contents of this test tube may look like some vile concoction from a mad science lab, but they are in fact the remnants of a marine plant called eelgrass, Zostera marina.
Understanding species interactions and population dynamics are important for tracking the success and spread of threatened and endangered species. But how can scientists accurately track these data for species that look the same and cannot be identified via visual comparisons of two individuals? The answer may lie in the realm of conservation genetics and genomics. In addition to being able to provide species-level identification (and even individual-level identification), this field obtains and analyzes organisms’ genetic material to gain insight into population functions.
Rachel Bay received a Sloan Foundation fellowship to fund research on the molecular mechanisms of thermal tolerance in corals, an increasingly critical physiological process as ocean temperatures shift and warming events occur.
