Pattern formation in diffusive predator-prey systems with predator-taxis and prey-taxis
Discrete & Continuous Dynamical Systems - B, 2021 A reaction-diffusion predator-prey system with prey-taxis and predator-taxis describes the spatial interaction and random movement of predator and prey species, as well as the spatial movement of predators pursuing prey and prey evading predators.

Combining impact of velocity, fear and refuge for the predator–prey dynamics
Journal of Biological Dynamics, 2023 We develop a deterministic predator–prey compartmental model to investigate the impact of their velocities on their interactions. Prey hides in a refuge area and comes out of this area when predation pressure declines.

Go big or … don't? A field-based diet evaluation of freshwater piscivore and prey fish size relationships. [PDF]
PLoS ONE, 2018 Body size governs predator-prey interactions, which in turn structure populations, communities, and food webs. Understanding predator-prey size relationships is valuable from a theoretical perspective, in basic research, and for management applications ...

Noise-guided evolution within cyclical interactions [PDF]
, 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
Mathematical 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]
, 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 ...

Scientific 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]
, 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).

Dynamics and pattern formation in diffusive predator-prey models with predator-taxis
Electronic Journal of Differential Equations, 2020 We consider a three-species predator-prey system in which the predator has a stage structure and the prey moves to avoid the mature predator, which is called the predator-taxis.

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