Description
Summary:In this research, we studied two species populations competing for a shared biotic resource in the environment with harvesting effects. Variable environmental carrying capacity represents the limited biotic resource available. Studies were done to investigate the effects of the enrichment parameter of the resource that sets the primary bifurcation parameter in the models. However, the models studied neglected the effects of population harvesting. Adding harvesting terms to the model would generate different kinds of dynamics in the system's behaviour. We investigated the steady�state solutions and their corresponding eigenvalues. The results can be displayed as bifurcation diagrams, which are useful in visualising the steady-state solution branches that exist in the system.
