Fluctuations and Correlations in Lattice Models for Predator-Prey Interaction

open access: yes, 2006
Including spatial structure and stochastic noise invalidates the classical Lotka-Volterra picture of stable regular population cycles emerging in models for predator-prey interactions.

Spatial stochastic predator-prey models [PDF]

open access: yes, 2006
We consider a broad class of stochastic lattice predator-prey models, whose main features are overviewed. In particular, this article aims at drawing a picture of the influence of spatial fluctuations, which are not accounted for by the deterministic ...

Prey–predator optimal harvesting mathematical model in the presence of toxic prey under interval uncertainty

open access: yesScientific African, 2023
This paper explores a multispecies prey–predator harvesting system based on Lotka–Volterra model with two preys (palatable and toxic prey) and one predator with interval biological parameters.

Effects of demographic stochasticity on biological community assembly on evolutionary time scales

open access: yes, 2010
We study the effects of demographic stochasticity on the long-term dynamics of biological coevolution models of community assembly. The noise is induced in order to check the validity of deterministic population dynamics.

Conditions for permanence and ergodicity of certain stochastic predator–prey models [PDF]

open access: yesJournal of Applied Probability, 2015
In this paper we derive sufficient conditions for the permanence and ergodicity of a stochastic predator–prey model with a Beddington–DeAngelis functional response. The conditions obtained are in fact very close to the necessary conditions.

Effects of Behavioral Tactics of Predators on Dynamics of a Predator-Prey System

open access: yesAdvances in Mathematical Physics, 2014
A predator-prey model incorporating individual behavior is presented, where the predator-prey interaction is described by a classical Lotka-Volterra model with self-limiting prey; predators can use the behavioral tactics of rock-paper-scissors to dispute

Evolutionary tradeoff and equilibrium in an aquatic predator-prey system [PDF]

open access: yes, 2004
Due to the conventional distinction between ecological (rapid) and evolutionary (slow)timescales, ecological and population models to date have typically ignored the effects of evolution.

Hunting‐mediated predator facilitation and superadditive mortality in a European ungulate

open access: yesEcology and Evolution, 2018
Predator‐prey theory predicts that in the presence of multiple types of predators using a common prey, predator facilitation may result as a consequence of contrasting prey defense mechanisms, where reducing the risk from one predator increases the risk ...

Impacts of predator–prey interaction on managing maximum sustainable yield and resilience

open access: yesNonlinear Analysis, 2020
This paper gives a broad outline of some comparative analysis of two ecological services, namely, yield and resilience of a generalist predator–prey system.
