Rebecca Gast

Rebecca Gast

Associate Scientist with Tenure

Research Interests: I'm interested in how marine protists (algae and protozoa) not only survive, but thrive, in the extremes of polar marine environments. In particular, I am studying two alternative modes of nutrition acquisition that may play roles in helping algae to survive the 3-4 months of darkness during polar winters. My work focuses on algae that can consume particles (mixotrophy) and a dinoflagellate that steals chloroplasts (kleptoplasty) from another alga in order to become photosynthetic. Our work suggests that in the Antarctic, mixotrophic algae, rather than traditional heterotrophs, are the important consumers of bacteria in the spring, which could affect the flow of carbon through the food web. In the Arctic, we found that picoeukaryotic phytoplankton were potentially consuming more of the bacterial biomass in the fall than either larger mixotrophic algae or the heterotrophic protists were, again potentially impacting where carbon goes. Currently I am using transcriptomic approaches to understand how the dinoflagellate maintains the stolen chloroplasts, and how different mixotrophs regulate genes associated with phagocytosis.

Michelle Shero

Associate Scientist

Research Interests: The Shero Lab focuses on the linkages between energy balance and physiological condition, behavior, and reproductive success of marine mammals. Understanding how these are ultimately linked with complex, multifaceted traits such as performance and life-long animal fitness has important implications for population dynamics and conservation.

Sam Laney

Sam Laney

Associate Scientist with Tenure

Research Interests: I'm an oceanographer and engineer with broad interests in marine phytoplankton ecology. The questions that motivate me the most are those that examine how phytoplankton respond to changes in the oceanic light environment.
