Advances in Difference Equations, 2020 In this paper, we propose a single species logistic model with feedback control and additive Allee effect in the growth of species. The basic aim of the paper is to discuss how the additive Allee effect and feedback control influence the above model’s ...

On the fractional Allee logistic equation in the Caputo sense
Examples and Counterexamples, 2023 In the framework of population models, logistic growth and fractional logistic growth has been analyzed. In some situations the so-called Allee effect gives more accurate approximation.

Dynamics Analysis of a Discrete-Time Commensalism Model with Additive Allee for the Host Species
Axioms, 2023 We propose and study a class of discrete-time commensalism systems with additive Allee effects on the host species. First, the single species with additive Allee effects is analyzed for existence and stability, then the existence of fixed points of ...

Modeling the Allee effect and fear effect in predator–prey system incorporating a prey refuge
Advances in Difference Equations, 2020 In this paper, we consider a predator–prey model with Allee effect, fear effect and prey refuge. By considering the prey refuge as a parameter, we give the threshold condition for the stability of the system, and prove that the system undergoes a ...

Review: Allee effects in social species [PDF]
Journal of Animal Ecology, 2017 Abstract Allee effects have important implications for many aspects of basic and applied ecology. The benefits of aggregation of conspecific individuals are central to Allee effects, which have led to the widely held assumption that social species are more prone to Allee effects. Robust evidence for this assumption, however, remains rare. Furthermore,

Chance Establishment for Sexual, Semelparous Species: Overcoming the Allee Effect
, 2009 We formalize the establishment process for a sexual, semelparous organism through the use of hierarchical probability modeling from parameters of survival, probability of being female, probability of being fertilized, and expected fecundity.We show how ...

Unidirectional Migration of Populations with Allee Effect [PDF]
, 2023 In this note we consider two populations living on identical patches, connected by unidirectional migration, and subject to strong Allee effect. We show that by increasing the migration rate, there are more bifurcation sequences than previous works ...

Mathematics, 2023 In this paper, we propose a diffusive predator–prey model with a strong Allee effect and nonlocal competition in the prey and a fear effect and gestation delay in the predator.

Does the CEO's Attention Affect How Well the Firm Performs Environmentally?
Business Strategy and the Environment, EarlyView.ABSTRACT This study explores whether CEOs' environmental attention (CEA) enhances firms' environmental performance. Drawing on attention‐based and upper echelons theories, which emphasize that executives' cognitive focus shapes organizational outcomes, we argue that CEOs who devote greater attention to environmental issues are more likely to integrate ...
