Colloquium

Topic: Mathematical insights in plankton swimming and aggregation.

Lou Rossi - Delaware (Host: Zhao)

Abstract:

Plankton is a general term for a wide range of floating or drifting organisms in fresh and saltwater.  Plankton are of considerable scientific interest for a number of reasons.  For one, they are an important food source for larger creatures.  Also, they process about 60\% of the marine carbon, and they consume a significant fraction of man-made CO$_2$ and produce about half of the atmospheric oxygen.  In this talk, we focus on some experimental, analytical and computational efforts to understand Heterosigma akashiwo a type of plankton responsible for some harmful algal blooms.  These are swimming plankton, capable of inefficient photosynthesis and predation.   Their behavior is a direct response of local chemical and optical cues, so a fundamental understanding of how they swim is essential to anticipating changes in marine ecology in response to climate change and ocean acidification.  In particular, we demonstrate that these plankton emit a chemical signal that in turn impacts the plankton density.  In this talk, I will discuss a research program at the University of Delaware to mathematically model, analyze and understand complex plankton behavior including swarming.  These activities include careful experiments to isolate specific behaviors and connect them to a unique coupling of well-established processes in swimming motion, chemotaxis and auto-chemotaxis.
