Biological growth curves are central to interdisciplinary research that seeks to improve our
understanding of natural processes. Applications of growth equations are widespread …

The paper presents the study of one prey one predator harvesting model with imprecise
biological parameters. Due to the lack of precise numerical information of the biological …

We consider a tri-trophic stochastic food-chain model with harvesting. We first establish
critical values between persistence in mean and extinction for each species. The results …

In this paper, we use a Markovian switching process to model the telephone noise in the
environment, and propose a stochastic regime-switching predator–prey model with …

This paper is concerned with a stochastic Leslie–Gower Holling-type II predator–prey
system with regime switching and prey harvesting. Firstly, sharp sufficient criteria for the …

Taking the stochastic effects on growth rate and harvesting effort into account, we propose a
stochastic delay model of species in two habitats. The main aim of this paper is to investigate …

Considering that over exploitation would result in the extinction of the population, we
propose and investigate a Holling II functional response prey-predator model with …

This paper introduces an imprecise prey–predator model by using interval and fuzzy number
in modeling of prey and predator interaction. In a prey–predator system, values of the …

This note is concerned with the optimal harvesting of a stochastic logistic model with time
delay. The classical optimal harvesting question of this type of model is difficult because it is …

This research focuses on optimal impulsive harvesting strategy of a stochastic Gompertz
model with periodic coefficients. By investigating the associated Hamilton function, the …
