A solution to the evolution-related Truscott-Brindley model for the   generalized phytoplankton-zooplankton populations
  Phytoplankton are tiny floating plants (algae) living in oceans. In the process of photosynthesis, phytoplankton produces half of the world's oxygen. Moreover, by primary production, death and sinking, they transport carbon from the ocean's surface layer to marine sediments. There are many species of phytoplankton that can be distinguished according to morphology.   In this paper, we investigate the generalised Truscott-Brindley model of the dynamics of zoologically defined interacting populations which have spatial structure. Specifically, we consider conjointly marine phytoplankton and zooplankton populations, and model them as an excitable medium. The resolution using the Boubaker polynomials expansion scheme (BPES) along with stability analysis is carried out.
