Mathematical Modelling of Predatory Prokaryotes [PDF]

open access: yes, 2006
Predator–prey models have a long history in mathematical modelling of ecosystem dynamics and evolution. In this chapter an introduction to the methodology of mathematical modelling is given, with emphasis on microbial predator–prey systems, followed by a

Bistability induced by generalist natural enemies can reverse pest invasions [PDF]

open access: yes, 2016
Reaction-diffusion analytical modeling of predator-prey systems has shown that specialist natural enemies can slow, stop and even reverse pest invasions, assuming that the prey population displays a strong Allee effect in its growth.

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.

A synthetic Escherichia coli predator–prey ecosystem [PDF]

open access: yes, 2008
We have constructed a synthetic ecosystem consisting of two Escherichia coli populations, which communicate bi-directionally through quorum sensing and regulate each other's gene expression and survival via engineered gene circuits.

Mathematical Analysis of Discrete Fractional Prey-Predator Model with Fear Effect and Square Root Functional Response

open access: yesCumhuriyet Science Journal, 2022
This paper investigates the dynamics of a discrete fractional prey-predator system. The prey-predator interaction is modelled using the square root functional response, which appropriately models systems in which the prey exhibits a strong herd structure,

Multiple positive periodic solutions of a Gause-type predator-prey model with Allee effect and functional responses

open access: yesAIMS Mathematics, 2020
This paper deals with a Gause-type predator-prey model with Allee effect and Holling type III functional response. We also consider the influence of predator competition and the artificial harvesting on predator-prey system.

Dynamics of a Predator–Prey Model with Impulsive Diffusion and Transient/Nontransient Impulsive Harvesting

open access: yesMathematics, 2023
Harvesting is one of the ways for humans to realize economic interests, while unrestricted harvesting will lead to the extinction of populations. This paper proposes a predator–prey model with impulsive diffusion and transient/nontransient impulsive ...

Modelling the dynamics of traits involved in fighting-predators–prey system [PDF]

open access: yes, 2015
We study the dynamics of a predator–prey system where predators fight forcaptured prey besides searching for and handling (and digestion) of the prey. Fighting for prey is modelled by a continuous time hawk–dove game dynamics where the gain depends on ...

Transport of inertial particles by Lagrangian coherent structures : application to predator-prey interaction in jellyfish feeding [PDF]

open access: yes, 2009
We use a dynamical systems approach to identify coherent structures from often chaotic motions of inertial particles in open flows. We show that particle Lagrangian coherent structures (pLCS) act as boundaries between regions in which particles have ...
