Prey and predator density‐dependent interactions under different water volumes

open access: yesEcology and Evolution, 2021
Predation is a critical ecological process that directly and indirectly mediates population stabilities, as well as ecosystem structure and function. The strength of interactions between predators and prey may be mediated by multiple density dependences ...

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.

Dynamical study of the theta-logistic predator-prey model incorporating gregarious behavior of prey

open access: yesMathematics in Applied Sciences and Engineering, 2023
Relation between species and their livelihood environment in ecological systems is very complex. For that reason, in order to study predator-prey  relations, modeling is essential in biomathematics.

Applying allometric scaling to predator-prey systems [PDF]

open access: yes, 2019
In population dynamics, mathematical models often contain too many parameters to be easily testable. A way to reliably estimate parameters for a broad range of systems would help us obtain clearer predictions from theory.

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

open access: yesPLoS 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.

open access: yesPLoS 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 ...

A non-autonomous stochastic predator-prey model

open access: yesMathematical 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 ...

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

open access: yesPeerJ, 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.

Bacterial predator-prey coevolution accelerates genome evolution and selects on virulence-associated prey defences

open access: yesNature Communications, 2019
Generalist bacterial predators are likely to strongly shape many important ecological and evolutionary features of microbial communities, for example by altering the character and pace of molecular evolution, but investigations of such effects are scarce.
