In theoretical ecology, predator–prey interaction is a natural phenomenon that significantly
contributes for shaping the community structure and maintaining the ecological diversity. In …

Study of a food chain model under uncertainty is quite difficult. Because, in an uncertain food
chain model, the biological parameters can't be determined accurately. The aim of this work …

This study considers the classical Lotka–Volterra model for a prey–predator system with
harvesting effort and catchability coefficients for both species incorporating a new prey …

Refuge for prey and additional food for predator together with environmental fluctuation is a
very interesting topic for dynamical system. In this work we have studied a prey–predator …

Different types of stochasticity play essential roles in shaping complex population dynamics.
This paper presents a novel approach to model demographic and environmental …

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 …

We propose a generalization of conformable calculus for Type-2 interval-valued functions.
We investigated the differentiability and integrability properties of such functions. The …

This paper is devoted to the study of ecosystem based fisheries management. The model
represents the interaction between prey and predator population with Holling II functional …

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 …

Intense harvesting and emerging infectious diseases are potential threats to global fishery. A
proper management policy equipped with the scientific understanding of species interaction …
