Animal Plume-Tracing Behavior in Wave Influenced Flow Domains

摘要

We elucidated search algorithms used by benthic marine animals (mantis shrimp) when finding an odorant source in wave-influenced coastal flow versus in unidirectional flow. We did so by quantifying animal behavior when finding odorant sources in waves versus unidirectional flow in a flume while simultaneously using planar laser-induced fluorescence (PLF) to quantify the instantaneous concentration structure of the odor plume around the olfactory when the animals execute specific behaviors. The search rules we discovered (relating behaviors to the instantaneous plume environment near sensors) can be implemented in artificial systems operating in coastal environments.
