Predator–prey interactions: Strategic biting

Current Biology, 2022
The nematode Pristionchus pacificus occasionally encounters other nematode species that compete for similar resources. A new study shows that P. pacificus perform an aggressive patrolling and biting behavior to expel adult Caenorhabditis elegans nematodes from food patches.

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 Molecular Ecosystems

ACS Nano, 2012
Biological organisms use intricate networks of chemical reactions to control molecular processes and spatiotemporal organization. In turn, these living systems are embedded in self-organized structures of larger scales, for example, ecosystems. Synthetic in vitro efforts have reproduced the architectures and behaviors of simple cellular circuits ...

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.
