A delay nonautonomous model for the impacts of fear and refuge in a three species food chain model with hunting cooperation

N Sk, PK Tiwari, S Pal - Mathematics and Computers in Simulation, 2022 - Elsevier
In this article, we study the dynamics of a three species food chain model for a predator–prey
system with hunting cooperation in predators; due to fear of predation risk, prey population …

Dynamics of a stage-structured predator-prey model: cost and benefit of fear-induced group defense

P Panday, N Pal, S Samanta, P Tryjanowski… - Journal of Theoretical …, 2021 - Elsevier
In the predator-prey system, predators can affect the prey population (1) by direct killing and
(2) by inducing predation fear, which ultimately force preys to adopt some anti-predator …

Effects of fear, refuge and hunting cooperation in a seasonally forced eco-epidemic model with selective predation

S Roy, PK Tiwari, H Nayak, M Martcheva - The European Physical Journal …, 2022 - Springer
In ecological systems, the fear of predation risk may assert privilege to the prey species by
restricting their exposure to potential predators, and also impose costs by constraining the …

A nonautonomous model for the interactive effects of fear, refuge and additional food in a prey–predator system

N Sk, PK Tiwari, Y Kang, S Pal - Journal of Biological Systems, 2021 - World Scientific
The importance of fear, refuge and additional food is being increasingly recognized in recent
studies, but their combined effects need to be explored. In this paper, we investigate the joint …

Two-fold impacts of fear in a seasonally forced predator–prey system with Cosner functional response

D Barman, S Roy, PK Tiwari, S Alam - Journal of Biological Systems, 2023 - World Scientific
In this paper, we investigate the dynamics of a predator–prey system of an ecological
community in which the fear instigated by the predators has an adverse effect on the …

Schooling behavior in a generalist predator–prey system: exploring fear, refuge and cooperative strategies in a stochastic environment

S Mandal, PK Tiwari - The European Physical Journal Plus, 2024 - epjplus.epj.org
Our research investigates the dynamic interactions within a predator–prey system,
considering factors like fear, carry-over effects, refuge use, and cooperative hunting. We …

Organized periodic structures and coexistence of triple attractors in a predator–prey model with fear and refuge

S Garai, NC Pati, N Pal, GC Layek - Chaos, Solitons & Fractals, 2022 - Elsevier
We report the existence of periodic structures viz., Arnold tongues, and shrimp-shaped
structures in the transitional and chaotic regimes in bi-parameter spaces of a predator–prey …

Dynamical behaviors of a constant prey refuge ratio-dependent prey–predator model with Allee and fear effects

S Pal, P Panday, N Pal, AK Misra… - International Journal of …, 2024 - World Scientific
In this paper, we consider a nonlinear ratio-dependent prey–predator model with constant
prey refuge in the prey population. Both Allee and fear phenomena are incorporated …

[HTML][HTML] The effect of the fear factor on the dynamics of an eco-epidemiological system with standard incidence rate

C Zhang - Infectious Disease Modelling, 2024 - Elsevier
In order to protect endangered prey, ecologists suggest introducing parasites into predators
which have achieved the expected goal in practice. Then how to explain the inherent …

Complex dynamics of a predator–prey system with fear and memory in the presence of two discrete delays

S Pal, A Gupta, AK Misra, B Dubey - The European Physical Journal Plus, 2023 - Springer
In this paper, we consider a two-species predator–prey model with fading memory, where
the growth rate of prey species is subject to predation induced fear. Growth rate of predator …
