EP44A:
Ecological Fluid Mechanics: Interactions Among Organisms and Their Fluid Environment I Posters


Session ID#: 22251

Session Description:
The session will be dedicated to reports from studies of interactions among organisms and their fluid environment. The session addresses the role that fluid motion, flow gradients, and chemical stirring play in shaping organism behavior, interactions, recruitment, reproduction, and community structure. Relevant studies span topics of biomechanics, transport and settling, propulsion, and sensory ecology. Themes may include the influence of instantaneous flow patterns, the influence of extreme physical events, the influence of scale on the biological-physical coupling, and biological/ecological advantages mediated by flow and chemical transport. For instance, what can we learn from how organisms balance physical versus biological forcing? We invite studies addressing a broad range of flow regimes spanning creeping, laminar, unsteady, wavy, and turbulent flows.
