Evolutionary Diversification of Prey and Predator Species Facilitated by Asymmetric Interactions. [PDF]

PLoS ONE, 2016
We investigate the influence of asymmetric interactions on coevolutionary dynamics of a predator-prey system by using the theory of adaptive dynamics.

Influence of habitat complexity on the prey mortality in IGP system involving insect predators (Heteroptera) and prey (Diptera): Implications in biological control.

PLoS ONE, 2022
Intraguild predation (IGP) is common in the freshwater insect communities, involving a top predator, intraguild prey (IG prey) and a shared prey. Influence of the habitat complexity on the prey-predator interactions is well established through several ...

The behavioral response of prey fish to predators: the role of predator size [PDF]

PeerJ, 2017
Predation is one of the key factors governing patterns in natural systems, and adjustments of prey behaviors in response to a predator stimulus can have important ecological implications for wild fish.

A non-autonomous stochastic predator-prey model

Mathematical Biosciences and Engineering, 2013
The aim of this paper is to consider a non-autonomous predator-prey-like system, with a Gompertz growth law for the prey.By introducing random variations in both prey birth and predator death rates,a stochastic model for the predator-prey-like system ...

Chemotactic predator-prey dynamics

, 2010
A discrete chemotactic predator-prey model is proposed in which the prey secrets a diffusing chemical which is sensed by the predator and vice versa. Two dynamical states corresponding to catching and escaping are identified and it is shown that steady ...

Mathematical exploration on control of bifurcation for a 3D predator-prey model with delay

AIMS Mathematics
In this current paper, we developed a new predator-prey model accompanying delay based on the earlier works. By applying inequality strategies, fixed point theorem, and a suitable function, we got new necessary conditions for the existence, uniqueness ...

Fluctuations and Correlations in Lattice Models for Predator-Prey Interaction

, 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]

, 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

Scientific 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.
