Competition coefficients, biodiversity loss, biodiversity gain, numerical scheme, initial condition, intrinsic growth rate.


The notion of a biodiversity loss has been identified as a major devastating biological phenomenon which needs to be mitigated against. In the short term, we have utilised a Matlab numerical scheme to quantify the effects of decreasing and increasing the inter – competition coefficients on biodiversity loss and biodiversity gain. On the simplifying assumption of a fixed initial condition(4,10), two enhancing factors of intrinsic growth rates, two inhibiting growth rates of intra – competition coefficients and two inhibiting growth rates of inter – competition coefficients. The novel results that we have obtained; which we have not seen elsewhere complement our recent contribution to knowledge in the context of applying a numerical scheme to predict both biodiversity loss and biodiversity gain.
