Stochastic description of the deterministic Ricker's population model
  We adopt the '0-1' test for chaos using Brownian motion chains to identify the dynamics of the Ricker's population model. In the '0-1' test '0' is related to regular motion while '1' is associated with chaotic motion. The identified regular and chaotic types of solutions have been confirmed by means of recurrence plots.
