Periodic solutions of logistic type population model with harvesting
We consider a bifurcation problem arising from population biology du(t) dt = f(u(t))− εh(t), where f(u) is a logistic type growth rate function, ε ≥ 0, h(t) is a continuous function of period T such that ∫ T 0 h(t)dt > 0. We prove that there exists an ε0 > 0 such that the equation has exactly two T -periodic solutions when 0 < ε < ε0, exactly one T -periodic solution when ε = ε0, and no T -peri...
متن کاملMultiple periodic solutions for a general class of delayed cooperative systems on time scales
In this paper, we consider a general class of delayed nonautonomous logistic Lotka-Volterra type multispecies cooperative system with harvesting terms on time scales. The model invovles the intraspecific cooperative terms defined by functions which depend on population densities. An existence theorem of at least 2n periodic solutions is established by using the coincidence degree theory. An exa...
متن کاملPeriodic Solutions and Positive Solutions of First and Second Order Logistic Type ODEs with Harvesting
It was recently shown that the nonlinear logistic type ODE with periodic harvesting has a bifurcation on the periodic solutions with respect to the parameter : u′ = f(u)− h(t). Namely, there exists an 0 such that for 0 < < 0 there are two periodic solutions, for = 0 there is one periodic solution, and for > 0 there are no periodic solutions, provided that ∫ T 0 h(t)dt > 0. In this paper we look...
متن کاملAn existence results on positive solutions for a reaction-diffusion model with logistics growth and indefinite weight
In this paper, using sub-supersolution argument, we prove an existence result on positive solution for an ecological model under certain conditions. It also describes the dynamics of the fish population with natural predation and constant yield harvesting. The assumptions are that the ecosystem is spatially homogeneous and the herbivore density is a constant which are valid assumptions for mana...
متن کاملOptimal impulsive harvesting policy for single population
In this paper, we established the exploitation of impulsive harvesting single autonomous population model by Logistic equation. By some special methods, we analysis the impulsive harvesting population equation and obtain existence, the explicit expression and global attractiveness of impulsive periodic solutions for constant yield harvest and proportional harvest. Then, we choose the maximum su...
