Bifurcation insight for a fractional‐order stage‐structured predator–prey system incorporating mixed time delays

Mathematical methods in the applied sciences, 2023
In this study, we principally investigate a fractional‐order stage‐structured predator–prey system including distributed time delays and discrete time delays.

The influence of human activity on predator-prey spatiotemporal overlap.

Journal of Animal Ecology, 2023
Despite growing evidence of widespread impacts of humans on animal behavior, our understanding of how humans reshape species interactions remains limited.

Spatially inhomogeneous bifurcating periodic solutions induced by nonlocal competition in a predator–prey system with additional food

Mathematical methods in the applied sciences, 2022
The nonlocal competition in prey is incorporated into a diffusive predator–prey model with additional food in predator and time delay. The local stability of the coexisting equilibrium is studied by analyzing the eigenvalue spectrum.

A study on fractional predator–prey–pathogen model with Mittag–Leffler kernel‐based operators

Numerical Methods for Partial Differential Equations, 2020
This paper aims to present a novel study on the dynamics of a fractional predator–prey–pathogen model to investigate the existence of the chaos in the model. We applied the Atangana–Baleanu fractional operator to the predator–prey–pathogen model, and new

Predator–prey interactions between droplets driven by non-reciprocal oil exchange

Nature Chemistry, 2019
Chemotactic interactions are ubiquitous in nature and can lead to non-reciprocal and complex emergent behaviour in multibody systems. However, developing synthetic, inanimate embodiments of a chemomechanical framework to generate non-reciprocal ...

Zooming in on mechanistic predator-prey ecology: integrating camera traps with experimental methods to reveal the drivers of ecological interactions.

Journal of Animal Ecology, 2020
Camera trap technology has galvanized the study of predator-prey ecology in wild animal communities by expanding the scale and diversity of predator-prey interactions that can be analyzed.

The effect of the fear factor on the dynamics of a predator-prey model incorporating the prey refuge.

Chaos, 2019
In this paper, we investigate the dynamics of an improved Leslie-Gower predator-prey model which is characterized by the reduction of the prey growth rate due to fear of the predator (i.e., antipredator behavior).

Role of Fear in a Predator–Prey Model with Beddington–DeAngelis Functional Response

Zeitschrift für Naturforschung A, 2019
In the present article, we investigate the impact of fear effect in a predator–prey model, where predator–prey interaction follows Beddington–DeAngelis functional response.

Mathematical and numerical analysis of a three‐species predator‐prey model with herd behavior and time fractional‐order derivative

Mathematical methods in the applied sciences, 2019
In this paper, we investigate with a time fractional‐order derivative in a three‐species predator‐prey model with the presence of prey social behavior.

Numerical solution of predator-prey model with Beddington-DeAngelis functional response and fractional derivatives with Mittag-Leffler kernel.

Chaos, 2019
One of the major applications of the nonlinear system of differential equations in biomathematics is to describe the predator-prey problem. In this framework, the fractional predator-prey model with Beddington-DeAngelis is examined.
