• Numerical Approach to A Mathematical Model of Three Species Ecological Ammensalism

Abstract

The present paper aims at the investigation of a three species ecosystem consisting of a prey (N1), a predator (N2) surviving on N1 and an enemy (N3) Ammansal with the prey N1 only. The mathematical model equations are formed by a set of three first order non-linear simultaneous equations in N1, N2 and N3. The equation for N3 is non-linear but de-coupled with N1and N2 .The relations among the natural growth rate of Ammensal- prey and the dominance reversal times(t*) are identified. More over the interactions among the three species are observed and some conclusions are established by Numerical study.
