Evolution in predator-prey systems
We study the adaptive dynamics of predator prey systems modeled by a dynamical system in which the characteristics are allowed to evolve by small mutations. When only the prey are allowed to evolve, and the size of the mutational change tends to 0, the system does not exhibit prey coexistence and the parameters of the resident prey type converges to the solution of an ODE. When only the predato...
متن کاملAn impulsively perturbed pest management model in which n predator species share a common prey
This paper investigates the dynamics of a competitive single-prey n-predators model of integrated pest management, which is subject to periodic and impulsive controls, from the viewpoint of finding sufficient conditions for the extinction of prey and for prey and predator permanence. The per capita death rates of prey due to predation are given in abstract, unspecified forms, which encompass la...
متن کاملTwo Generalized Predator-Prey Models for Integrated Pest Management with Stage Structure and Disease in the Prey Population
and Applied Analysis 3 where we denote P = {1, 2, . . . , p} and P 1 = {1, 2, . . . , p − 1} throughout the paper. Case 2. Natural enemies releases are more frequent than the release of the infective pests. We release the infective pests impulsively with releasing amount q 1 . Assume that τ n+1 − τ n ≡ T k holds for all n ∈ Z + , where T k is the period of releasing the infective pests. During ...

متن کاملThe Lotka-Volterra Predator-Prey Equations
One may find out the application of mathematics in the areas of ecology, biology, environmental sciences etc. Mathematics is particulary used in the problem of predator-prey known as lotka-Volterra predator-prey equations. Indeed, differential equations is employed very much in many areas of other sciences. However, most of natural problems involve some unknown functions...
