Hidden Allee effect in photosynthetic organisms [PDF]
In ecology and population biology, logistic equation is widely applied for simulating the population of organisms. By combining the logistic model with the low-density effect called Allee effect, several variations of mathematical expressions have been ...

Allee effects and the Allee-effect zone in northwest Atlantic cod. [PDF]
According to the theory of compensatory dynamics, depleted populations should recover when the threat responsible for their decline is removed because per capita population growth is assumed to be highest when populations are at their smallest viable sizes.

Enhancement of extreme events through the Allee effect and its mitigation through noise in a three species system [PDF]
We consider the dynamics of a three-species system incorporating the Allee Effect, focussing on its influence on the emergence of extreme events in the system.

Can a Mate‐Finding Allee Effect Be Elicited to Help Eradicate Invasive Mammals? [PDF]
The Allee effect is an important ecological process that has implications for extinction of endangered species and for assisting the management of invasive species.

Optimal dispersal in ecological dynamics with Allee effect in metapopulations. [PDF]
How diffusion impacts on ecological dynamics under the Allee effect and spatial constraints? That is the question we address. Employing a microscopic minimal model in a metapopulation (without imposing nonlinear birth and death rates) we evince --- both ...

Management of invasive Allee species [PDF]
In this study, we use a discrete, two-patch population model of an Allee species to examine different methods in managing invasions. We first analytically examine the model to show the presence of the strong Allee effect, and then we numerically explore ...

Programmed Allee effect in bacteria causes a tradeoff between population spread and survival. [PDF]
Dispersal is necessary for spread into new habitats, but it has also been shown to inhibit spread. Theoretical studies have suggested that the presence of a strong Allee effect may account for these counterintuitive observations.

Chaos and bifurcations of a discretized Holling-II prey-predator model including prey refuge and Allee effect [PDF]
This study examines the dynamics of a discrete-time predator-prey system incorporating a Holling Type-II functional response, the Allee effect, and a refuge term. Through algebraic analysis, we establish the occurrence of Period-Doubling (PD) and Neimark-

Dynamical analysis of a Lotka Volterra commensalism model with additive Allee effect
We propose and analyze a Lotka-Volterra commensal model with an additive Allee effect in this article. First, we study the existence and local stability of possible equilibria.

Interaction between Allee effects caused by organism-environment feedback and by other ecological mechanisms. [PDF]
Understanding Allee effect has crucial importance for ecological conservation and management because it is strongly related to population extinction. Due to various ecological mechanisms accounting for Allee effect, it is necessary to study the influence
