Chemical Orientation in Turbulent Environments Above Natural Stream Substrates: The Role of Bed Roughness and Turbulence Structure on Search Mechanisms

Investigators: John P. Crimaldi, Paul A. Moore

Sponsor: National Science Foundation

Program: Sensory Systems (Dr. Linda Kennedy)

Funding Dates: July, 2002 - June 2006

Objective: Determine how the temporal and spatial structure in turbulent odor plumes influences the orientation behavior of crayfish over various types of natural substrate.

Student Investigators: Dan Dombroski, Ph.D. candidate

The image at left shows a live crayfish in the presence of a turbulent odor plume. The plume is visualized using a planar laser-induced fluorescence (PLIF) technique.
