Numerical Analysis of a Size-Structured Population Model with a Dynamical Resource

Oscar Angulo, J C Lopez-Marcos, M A Lopez-Marcos


In this paper, we analyze the convergence of a second order numerical method for the approximation of a size-structured population model whose dependency on the environment is managed by the evolution of a vital resource. Optimal rate of convergence is derived. Numerical experiments are also reported to demonstrate the predicted accuracy of the scheme. Also, it is applied for the solution of a problem that describes the dynamics of a Daphnia magna population, paying attention to the unstable case.
