Abstract: | A resource based ecological competition model with interference is proposed. The model is based on Lotka-Volterra dynamics with two predators competing for a single, limited prey. Interference effects are considered in this article. When the interference coefficient, expressing the damage effect from its rival, is small, the mathematical analysis shows that the winner in purely exploitative competition still outcompetes its rival. However, if the interference coefficient is large enough then the competition outcome will depend on initial population of predator species. |
