In this paper, a three-species food chain model is analytically investigated on theories of
ecology and using numerical simulation. Bifurcation diagrams are obtained for biologically …

We review several approaches for characterizing chaotic systems in view of their
comparison and discuss the advantages and limits of these approaches in the context of …

This paper investigates a three-species food chain model with a Beddington–DeAngelis
functional response, both analytically and through numerical simulations. First the …

In this paper, on the basis of the theories and methods of ecology and ordinary differential
equation, an ecological model with an impulsive control strategy is established. By using the …

The paper confronts chaos indicators of two basic types: spectral methods and variational
methods. The spectral methods include the spectral numbers and the integrated …

Chaos. A simple word but by no means a simple concept. Traditionally, as in the Bible,
chaos designates the initial states of the world before its organization by “God.” It arises from …

The dynamics underlying cereal crops in the northern region of Morocco is investigated
using a global modelling technique applied to a vegetation index time series derived from …

In this paper, using the theories and methods of ecology and ordinary differential equations,
an ecological model with an impulsive control strategy and a distributed time delay is …

Purpose Online question-and-answer (Q&A) communities serve as important channels for
knowledge diffusion. The purpose of this study is to investigate the dynamic development …
