Oscillatory behaviour in a lattice prey-predator system [PDF]
Physical Review E, 1999 Using Monte Carlo simulations we study a lattice model of a prey-predator system. We show that in the three-dimensional model populations of preys and predators exhibit coherent periodic oscillations but such a behaviour is absent in lower-dimensional ...

Forced prey-predator oscillations [PDF]
Journal of Mathematical Biology, 1981 In this paper existence and stability of subharmonic solutions of the Volterra-Verhulst equations with a periodic coefficient are analyzed by the method of Urabe. The study supports the view that the observed 4- and 10-yr cycles of prey-predator systems are due to seasonal fluctuations.

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.

On some Free Boundary Problems of the Prey-predator Model [PDF]
, 2014 In this paper we investigate some free boundary problems for the Lotka-Volterra type prey-predator model in one space dimension. The main objective is to understand the asymptotic behavior of the two species (prey and predator) spreading via a free ...

Prey–predator phenological mismatch under climate change [PDF]
Current Opinion in Insect Science, 2019 Insect phenology is affected by climate change and main responses are driven by phenotypic plasticity and evolutionary changes. Any modification in seasonal activity in one species can have consequences on interacting species, within and among trophic levels.

Leslie’s prey–predator model in discrete time [PDF]
International Journal of Biomathematics, 2020 We consider the Leslie’s prey–predator model with discrete time. This model is given by a nonlinear evolution operator depending on five parameters. We show that this operator has two fixed points and define type of each fixed point depending on the parameters.

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 ...

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 ...

Evolutionary Stability of Ecological Hierarchy [PDF]
, 2003 A self-similar hierarchical solution that is both dynamically and evolutionarily stable is found to the multi dimensional Lotka-Volterra equation with a single chain of prey-predator relations.
