recommendations! Published in 2018 at "Nonlinear Analysis: Hybrid Systems"

DOI: 10.1016/j.nahs.2017.08.001

Abstract: Abstract In this paper, a stochastic predator–prey model with modified Leslie–Gower Holling-type II schemes and impulsive toxicant input in polluted environments is developed and analyzed. The threshold between persistence in the mean and extinction is… read more here.

DOI: 10.1016/j.physa.2019.01.058

Abstract: Abstract In this paper, we study a stochastic predator–prey model with distributed delay and higher order perturbations. By the linear chain technique, we transform the stochastic system with weak kernel case into an equivalent degenerate… read more here.

DOI: 10.1080/07362994.2019.1710188

Abstract: Abstract In the present paper, we focus on a stochastic predator-prey model with stage structure for prey. Firstly, by using the stochastic Lyapunov function method, we obtain sufficient conditions for the existence and uniqueness of… read more here.

DOI: 10.1080/17513758.2023.2193211

Abstract: In this paper, a stochastic predator-prey model with two competitive preys and Ornstein-Uhlenbeck process is formulated and analysed, which is used to obtain a better understanding of the population dynamics. At first, we validate that… read more here.

DOI: 10.3390/axioms10040323

Abstract: Taking impulsive effects into account, an impulsive stochastic predator–prey system with the Beddington–DeAngelis functional response is proposed in this paper. First, the impulsive system is transformed into an equivalent system without pulses. Then, by constructing… read more here.
