Optimal Foraging Strategy: Angle Matters — •Udo Erdmann¹, Sebastian Göller¹, Lutz Schimansky-Geier¹, Igor M. Sokolov¹, and Frank Moss² — ¹Institut für Physik, Humboldt-Universität zu Berlin — ²Center for Neurodynamics, University of Missouri at St. Louis

We report a theory to describe the motion of zooplankton. Into contrast to move just randomly like a classical Brownian particle, zooplankters like Daphnia or Copepods pick their turning angle from a distribution which is far from being Gaussian or equally distributed. This leads to different behavior in the motion compared to normal diffusion. The question which can be asked here is: Is there an evolutionary reason to forage for food in the aforementioned manner? The talk is planned to give an answer into that direction.
