Stability Analysis of a Patchy Predator–Prey Model with Fear Effect

open access: yesAxioms, 2022
In this paper, a predator–prey model with fear effect and dispersal is proposed. Assume that only the prey migrates at a constant rate between patches and the migration of prey on each patch is faster than the time scale of local predator–prey ...

Fear information and social phobic beliefs in children: a prospective paradigm and preliminary results [PDF]

open access: yes, 2002
This paper presents a first attempt to develop a prospective paradigm to test Rachman’s (Behav. Res. Ther. 15 (1977) 375) theory of fear acquisition for social fears. Following the prospective paradigm for animal fears developed by Field et al.

Do non-direct heterospecific cues of avian predator activity alter reproductive modes of a passerine bird?

open access: yesThe European Zoological Journal, 2023
Predators affect prey by killing them or inducing changes in their physiology and behaviour through a fear effect associated with predation risk. In birds, perceived predation risk influences reproductive decisions, such as the reduction of parental ...

Spatiotemporal dynamics of a diffusive predator–prey model with fear effect

open access: yesNonlinear Analysis, 2022
This paper concerned with a diffusive predator–prey model with fear effect. First, some basic dynamics of system is analyzed. Then based on stability analysis, we derive some conditions for stability and bifurcation of constant steady state. Furthermore,

The effect of Midazolam and Propranolol on fear memory reconsolidation in ethanol-withdrawn rats: Influence of D-cycloserine [PDF]

open access: yes, 2014
Background: Withdrawal from chronic ethanol facilitates the formation of contextual fear memory and delays the onset to extinction, with its retrieval promoting an increase in ethanol consumption.

Fear Effect on a Predator–Prey Model with Non-Differential Fractional Functional Response

open access: yesFractal and Fractional, 2023
In this paper, we study the factor of the fear effect in a predator–prey model with prey refuge and a non-differentiable fractional functional response due to the group defense.

Effect of vicarious fear learning on children's heart rate responses and attentional bias for novel animals [PDF]

open access: yes, 2014
Research with children has shown that vicarious learning can result in changes to 2 of Lang's (1968) 3 anxiety response systems: subjective report and behavioral avoidance.

A BDNF sensitive mechanism is involved in the fear memory resulting from the interaction between stress and the retrieval of an established trace [PDF]

open access: yes, 2013
The present study investigates the fear memory resulting from the interaction of a stressful experience and the retrieval of an established fear memory trace.

Analysis of a Delayed Reaction-Diffusion Predator–Prey System with Fear Effect and Anti-Predator Behaviour

open access: yesMathematics, 2022
This paper is devoted to studying the dynamics of a delayed reaction-diffusion predator–prey system incorporating the effects of fear and anti-predator behaviour.

Long-Term Side Effects: A Mathematical Modeling of COVID-19 and Stroke with Real Data

open access: yesFractal and Fractional, 2023
The post-effects of COVID-19 have begun to emerge in the long term in society. Stroke has become one of the most common side effects in the post-COVID community.
