Extinction and Permanence of a General Predator-Prey System with Impulsive Perturbations
A general predator-prey system is studied in a scheme where there is periodic impulsive perturbations. This scheme has the potential to protect the predator from extinction but under some conditions may also serve to lead to extinction of the prey. Conditions for extinction and permanence are obtained via the comparison methods involving monotone theory of impulsive systems and multiple Liapuno...
متن کاملChaos in a Predator-Prey System with Impulsive Perturbations and Stage Structure for the Predator
We investigate a predator-prey model with stage structure for the predator and periodic constant impulsive perturbations. Conditions for extinction of prey and immature predator are given. By using the Floquet theory and small amplitude perturbation skills, we consider the local stability of prey, immature predator eradication periodic solution. Furthermore, by using the method of numerical sim...
متن کاملThe Permanence and Extinction of a Discrete Predator-Prey System with Time Delay and Feedback Controls
The dynamic relationship between predator and its prey has long been and will continue to be one of the dominant themes in both ecology and mathematical ecology due to its universal existence and importance. The traditional predator-prey models have been studied extensively e.g., see 1–10 and references cited therein , but they are questioned by several biologists. Thus, the Lotka-Volterra type...
متن کاملPermanence and Extinction of a Generalized Gause-Type Predator-Prey System with Periodic Coefficients
and Applied Analysis 3 Vance and Coddington 35 have studied system 1.4 and proved the existence of a unique periodic solution under some assumptions. Apart from the assumptionwementioned above that f ·, x is ω-periodic, the other assumptions with a mild modification are as follows. A1 Function f is continuous and differentiable with respect to x on R2 0, and ∂f/∂x is continuous on R2 0. A2 Ther...
متن کاملSpecies extinction and permanence of an impulsively controlled two-prey one-predator system with seasonal effects
Recently, the population dynamic systems with impulsive controls have been researched by many authors. However, most of them are reluctant to study the seasonal effects on prey. Thus, in this paper, an impulsively controlled two-prey one-predator system with the Beddington-DeAngelis type functional response and seasonal effects is investigated. By using the Floquet theory, the sufficient condit...
