چکیده
<p style='text-indent:20px;'>Environmental factors and random variation have strong effects on the dynamics of biological ecological systems. In this paper, we propose a stochastic delay differential model two-prey, one-predator system with cooperation among prey species against predator. The has global positive solution. Sufficient conditions existence uniqueness an ergodic stationary distribution solution are provided, by constructing suitable Lyapunov functionals. for possible extinction predator populations also obtained. expressed in terms threshold parameter <inline-formula><tex-math id="M1">\begin{document}$ {\mathcal R}_0^s $\end{document}</tex-math></inline-formula> that relies environmental noise. Illustrative examples numerical simulations, using Milstein's scheme, carried out to illustrate theoretical results. A small scale noise can promote survival species. While relative large noises lead such environment.</p>

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...
متن کاملDynamical Properties of a Delay Prey-Predator Model with Disease in the Prey Species Only
A three-dimensional ecoepidemiological model with delay is considered. We first investigate the existence and stability of the equilibria. We then study the effect of the time delay on the stability of the positive equilibrium. The existence of a Hopf bifurcation at the positive equilibrium is obtained through the study of an exponential polynomial equation with delay-dependent coefficients. Nu...
متن کاملA Time Delay Predator-Prey System with Three-Stage-Structure
A predator-prey system was studied that has a discrete delay, stage-structure, and Beddington-DeAngelis functional response, where predator species has three stages, immature, mature, and old age stages. By using of Mawhin's continuous theorem of coincidence degree theory, a sufficient condition is obtained for the existence of a positive periodic solution.
