Chaos was proposed in the 1970s as an alternative explanation for apparently noisy
fluctuations in population size. Although readily demonstrated in models, the search for …

In this work, three-dimensional nonlinear food chain system is numerically treated using the
computational heuristic framework of artificial neural networks (ANNs) together with the …

The present study is to investigate the Gudermannian neural networks (GNNs) using the
optimization procedures of genetic algorithm and active-set approach (GA-ASA) to solve the …

A three-dimensional continuous time dynamical system is considered. It is a model for a
tritrophic food chain, based on a modified version of the Leslie–Gower scheme. We …

Complex nonlinear dynamics are ubiquitous in marine ecology. Empirical dynamic
modelling can be used to infer ecosystem dynamics and species interactions while making …

Introduction to Mathematical Modeling and Chaotic Dynamics focuses on mathematical
models in natural systems, particularly ecological systems. Most of the models presented are …

The interplay of phytoplankton, zooplankton, and fish is one of the most important aspects of
the aquatic environment. In this paper, we propose to explore the dynamics of a …

A fairly realistic three-species food chain model based on the Leslie–Gower scheme is
investigated by using tools borrowed from the nonlinear dynamical systems theory. It is …

Fear of predators as an indirect effect of predation is a well-observed phenomenon in
natural predator–prey communities. After being popularized by Wang et al. in 2016 (J. Math …

This work presents the numerical performances of the fractional kind of food supply (FKFS)
model. The fractional kinds of the derivatives have been used to acquire the accurate and …
