Predator-Prey Model with Refuge, Fear and Z-Control

Ibrahim M. Elmojtaba, Kawkab Al-Amri, Qamar J.A. Khan · Sultan Qaboos University Journal for Science · 2021 · 10.53539/squjs.vol26iss1pp40-57

In this paper, we consider a predator-prey model incorporating fear and refuge. Our results show that the predator-free equilibrium is globally asymptotically stable if the ratio between the death rate of predators and the conversion rate of prey into predator is greater than the value of prey in refuge at equilibrium. …

Global Dynamics and Sensitivity Analysis of a Vector-Host-Reservoir Model

Ibrahim M. Elmojtaba, Santanu Biswas, Joydev Chattopadhyay · Sultan Qaboos University Journal for Science · 2016 · 10.24200/squjs.vol21iss2pp120-138

The role of animal reservoir in the disease dynamics is not yet properly studied. In the present investigation a mathematical model of a vector-host-reservoir is proposed and analyzed to observe the global dynamics of the disease. We observe that the disease free equilibrium is globally asymptotically stable if the bas …
