Existence and non-existence of spatial patterns in a ratio-dependent predator–prey model

M Banerjee, S Abbas - Ecological complexity, 2015 - Elsevier
In this paper, first we consider the global dynamics of a ratio-dependent predator–prey
model with density dependent death rate for the predator species. Analytical conditions for …

Spatiotemporal model of a predator–prey system with herd behavior and quadratic mortality

T Singh, S Banerjee - International Journal of Bifurcation and Chaos, 2019 - World Scientific
In this paper, we have investigated a diffusive predator–prey model with herd behavior. Also,
we considered that the mortality of predators is linear as well as quadratic. Using linear …

Dynamics of a predator–prey model with Allee effect on prey and ratio-dependent functional response

JD Flores, E González-Olivares - Ecological Complexity, 2014 - Elsevier
We analyze a ratio-dependent predator–prey model with Allee effect on the prey by making
a parametric analysis of the stability properties of the dynamics of the system in which the …

Dynamics of stage-structure predator-prey systems under density-dependent effect and mortality

B Ghosh, OL Zhdanova, B Barman, EY Frisman - Ecological Complexity, 2020 - Elsevier
We develop a four dimensional predator-prey system in continuous time with stage-structure
for both the communities. The reproduction rate of the prey and the transition rate for the …

Effects of density dependent cross-diffusion on the chaotic patterns in a ratio-dependent prey-predator model

N Mukherjee, S Ghorai, M Banerjee - Ecological Complexity, 2018 - Elsevier
Spatio-temporal chaos is an intriguing part of the spatio-temporal pattern formation,
observed in many interacting population models when their heterogeneous distributions …

Self-organised spatial patterns and chaos in a ratio-dependent predator–prey system

M Banerjee, S Petrovskii - Theoretical Ecology, 2011 - Springer
Mechanisms and scenarios of pattern formation in predator–prey systems have been a focus
of many studies recently as they are thought to mimic the processes of ecological patterning …

Emergent impacts of quadratic mortality on pattern formation in a predator–prey system

S Ghorai, S Poria - Nonlinear Dynamics, 2017 - Springer
In this paper, we have investigated the effects of spatial diffusion in the pattern formation of a
predator–prey system with quadratic mortality rate of the predator in the presence of habitat …

Spatiotemporal patterns induced by Turing and Turing-Hopf bifurcations in a predator-prey system

M Chen, R Wu, L Chen - Applied Mathematics and Computation, 2020 - Elsevier
Abstract The Turing and Turing-Hopf bifurcations of a Leslie-Gower type predator-prey
system with ratio-dependent Holling III functional response are investigated in this paper …

Patterns formations in a diffusive ratio-dependent predator–prey model of interacting populations

BI Camara, M Haque, H Mokrani - Physica A: Statistical Mechanics and Its …, 2016 - Elsevier
The present investigation deals with the analysis of the spatial pattern formation of a
diffusive predator–prey system with ratio-dependent functional response involving the …

Mortality can produce limit cycles in density-dependent models with a predator-prey relationship

T Mtar, R Fekih-Salem, T Sari - Discrete and Continuous Dynamical …, 2022 - hal.science
In this paper, we study an interspecific density-dependent model of two species competing
on a single nutrient in a chemostat, taking into account the predator-prey relationship …
