Mathematical Analysis of Discrete Fractional Prey-Predator Model with Fear Effect and Square Root Functional Response

open access: yesCumhuriyet Science Journal, 2022
This paper investigates the dynamics of a discrete fractional prey-predator system. The prey-predator interaction is modelled using the square root functional response, which appropriately models systems in which the prey exhibits a strong herd structure,

Global Dynamics of a Predator–Prey Model with Fear Effect and Impulsive State Feedback Control

open access: yesMathematics, 2022
In this paper, a predator–prey model with fear effect and impulsive state control is proposed and analyzed. By constructing an appropriate Poincaré map, the dynamic properties of the system, including the existence, nonexistence, and stability of ...

Bifurcation Analysis in a Harvested Modified Leslie–Gower Model Incorporated with the Fear Factor and Prey Refuge

open access: yesMathematics, 2023
Fear and prey refuges are two significant topics in the ecological community because they are closely associated with the connectivity of natural resources.

Dynamics and Bifurcation Analysis of an Eco-Epidemiological Model in a Crowley–Martin Functional Response with the Impact of Fear

open access: yesEngineering Proceedings, 2023
This article describes a three-species food web model that was developed by considering the interaction between susceptible prey, infected prey, and predator species.

Impact of fear in a prey-predator system with herd behaviour

open access: yesComputational and Mathematical Biophysics, 2021
Fear of predation plays an important role in the growth of a prey species in a prey-predator system. In this work, a two-species model is formulated where the prey species move in a herd to protect themselves and so it acts as a defense strategy.

Stability and Bifurcation in a Predator–Prey Model with the Additive Allee Effect and the Fear Effect

open access: yesMathematics, 2020
We proposed and analyzed a predator–prey model with both the additive Allee effect and the fear effect in the prey. Firstly, we studied the existence and local stability of equilibria.

Complex Dynamics of a Predator–Prey Interaction with Fear Effect in Deterministic and Fluctuating Environments

open access: yesMathematics, 2022
Many ecological models have received much attention in the past few years. In particular, predator–prey interactions have been examined from many angles to capture and explain various environmental phenomena meaningfully. Although the consumption of prey

Complex Dynamic Behaviors of a Modified Discrete Leslie–Gower Predator–Prey System with Fear Effect on Prey Species

open access: yesAxioms, 2022
A discrete modified Leslie–Gower prey-predator model considering the effect of fear on prey species is proposed and studied in this paper. First, we discuss the existence of equilibria and the local stability of the model.

The fear-increasing and fear-decreasing effects of a pilot policy to reduce fear of crime

open access: yesPLOS ONE, 2023
Fear of crime has been rising persistently in Chile, even in periods where actual crime rates have decreased, making the perception of crime an important policy issue. This paper presents the results of the impact evaluation of a pilot public policy designed to reduce fear of crime around a shopping centre in Santiago, Chile. The pilot policy consisted

Predator–Prey Models: A Review of Some Recent Advances

open access: yesMathematics, 2021
In recent years, predator–prey systems have increased their applications and have given rise to systems which represent more accurately different biological issues that appear in the context of interacting species.
