    • Fisher Equation with Turbulence in One Dimension 

      Benzi, Roberto; Nelson, David R. (Elsevier, 2009)
      As an example of life at high Reynolds number, we investigate the dynamics of the Fisher equation for the spreading of micro-organisms in one dimension subject to both turbulent convection and diffusion. We show that for ...

    • Population Dynamics at High Reynolds Number 

      Perlekar, Prasad; Benzi, Roberto; Nelson, David R.; Toschi, Federico (American Physical Society, 2010)
      We study the statistical properties of population dynamics evolving in a realistic two-dimensional compressible turbulent velocity field. We show that the interplay between turbulent dynamics and population growth and ...
