Noise-guided evolution within cyclical interactions [PDF]

open access: yes, 2007
We study a stochastic predator-prey model on a square lattice, where each of the six species has two superior and two inferior partners. The invasion probabilities between species depend on the predator-prey pair and are supplemented by Gaussian noise ...

A diffusive predator-prey system with prey refuge and predator cannibalism

open access: yesMathematical Biosciences and Engineering, 2019
This paper is devoted to exploring a diffusive predator-prey system with prey refuge and predator cannibalism. We investigate dynamics of this system, including dissipation and persistence, local and global stability of constant steady states, Turing ...

Geometric factors influencing the diet of vertebrate predators in marine and terrestrial environments [PDF]

open access: yes, 2014
Predator–prey relationships are vital to ecosystem function and there is a need for greater predictive understanding of these interactions. We develop a geometric foraging model predicting minimum prey size scaling in marine and terrestrial vertebrate ...

EXPLORING BIFURCATION IN A FRACTIONAL-ORDER PREDATOR-PREY SYSTEM WITH MIXED DELAYS

open access: yesJournal of Applied Analysis & Computation, 2020
This work chiefly develops and discusses a fractional-order predator-prey model with distributed delay and discrete delay. Applying skilly an appropriate variable substitution, a novel equivalent form of the fractional-order predator-prey model with ...

Increasing availability of palatable prey induces predator-dependence and increases predation on unpalatable prey

open access: yesScientific Reports, 2021
Understanding the factors governing predation remains a top priority in ecology. Using a dragonfly nymph-tadpole system, we experimentally varied predator density, prey density, and prey species ratio to investigate: (i) whether predator interference ...

Effects of demographic noise on the synchronization of a metapopulation in a fluctuating environment [PDF]

open access: yes, 2011
We use the theory of noise-induced phase synchronization to analyze the effects of demographic noise on the synchronization of a metapopulation of predator-prey systems within a fluctuating environment (Moran effect).

Numerical Simulation of Leslie-Gower Predator-Prey Model with Stage-Structure on Predator

open access: yesJournal of Experimental Life Science, 2018
In this paper, we introduce Leslie-Gower predator-prey model with a stage-structure population on the predator. This model consists of two populations, that are prey and predator populations. Here, we divide predator into two stages.

Delayed stability switches in singularly perturbed predator-prey models [PDF]

open access: yes, 2016
In this paper we provide an elementary proof of the existence of canard solutions for a class of singularly perturbed predator-prey planar systems in which there occurs a transcritical bifurcation of quasi steady states.

Modeling and Analysis of Predator-Prey Model with Fear Effect in Prey and Hunting Cooperation among Predators and Harvesting

open access: yesJournal of Applied Mathematics, 2022
In this paper, we present and analyze predator-prey system where prey population is linearly harvested and affected by fear and the prey population has grown logistically in the absence of predators.

Attraction and Avoidance between Predators and Prey at Wildlife Crossings on Roads

open access: yesDiversity, 2020
Wildlife passages are currently built at roads and railway lines to re-establish connectivity. However, little is known about whether predator-prey interactions may reduce the effectiveness of the crossing structures.
