“Fluid physics-mediated evolutionary convergence in motile behavior among marine plankton”

2:30 pm to 3:30 pm

Abstract:
Marine plankton are mostly microscopic and slow-moving relative to the macroscopic world. Thus, within the fluid immediately surrounding a plankter, the low-Reynolds-number fluid dynamics together with small-scale diffusion governs the transport of mass and momentum, thereby shaping the energy, matter, and information flows to and from the plankter. The small-scale fluid physics interfaces with the morphology, behavior, perception, response, and interaction of marine plankton to produce a variety of fascinating phenomena, patterns, processes, and functions that are fundamentally important to marine life, population and ecosystem functioning, and evolution. Although morphologically, physiologically, and genetically diverse, marine plankton live in the water environment that is governed by the same small-scale fluid physics; this has inevitably driven convergent evolution of some of their key behavioral traits. Here, we show such convergence through investigating a variety of small marine plankton using high-speed microscale imaging and fluid mechanics methods. We try to demonstrate that the small-scale fluid physics is a key factor that shapes the evolution of marine plankton.
Bio: Dr. Houshuo Jiang is a senior scientist in the Applied Ocean Physics and Engineering Department at Woods Hole Oceanographic Institution (WHOI). He received a B.S. degree in meteorology from Nanjing University, China in 1993 and a Ph.D. degree in oceanography from The Johns Hopkins University in 2000. He joined the WHOI staff in 2000 as a postdoctoral scholar, was appointed an assistant scientist in 2002, and was promoted to associate scientist in 2007 and to senior scientist in 2017. His research interests include small-scale biological-physical interactions, plankton fluid dynamics, ecological fluid dynamics, and ocean wind modeling.
