Jambura Journal of Mathematics, 2020 In this paper, the influence of additive Allee effect in prey and periodic harvesting in predator to the dynamics of the Leslie-Gower predator-prey model is proposed.

Evolution of mate-finding Allee effect in prey [PDF]
Journal of Theoretical Biology, 2018 The search for mates is often accompanied with conspicuous behaviour or morphology that can be exploited by predators. Here we explore the evolutionary consequences of a trade-off that arises naturally between mate acquisition and risk of predation and study evolution of the rate at which male prey search for mates in a population subject to a mate ...

Small, EarlyView.This study explores the covalent functionalization of Ti3C2Tx using 5,5′‐bis(triisopropoxysilyl)‐2,2′‐bipyridine in different solvents, revealing that only m‐xylene enables effective covalent bonding, ensuring structural stability and preventing layer swelling.

Dynamics of prey–predator model with strong and weak Allee effect in the prey with gestation delay
Nonlinear Analysis, 2020 This study proposes two prey–predator models with strong and weak Allee effects in prey population with Crowley–Martin functional response. Further, gestation delay of the predator population is introduced in both the models. We discussed the boundedness,

Dynamic behavior of commensal symbiosis system with both feedback control and Allee effect
上海师范大学学报. 自然科学版, 2022 The dynamic behavior of commensal symbiosis system with both feedback control and Allee effect is complex. In this paper，the influence of additive Allee effect on the dynamical behavior of the system has been studied based on the feedback control ...

Uncertain Logistic population model with Allee effect
Soft Computing, 2022 By considering the influence of various uncertain noises, we established an uncertain Logistic population model with Allee effect, which was characterized by an uncertain differential equation. Firstly, we obtained the solution of the model, and discussed the stability of the equilibrium state.

Relationship between spatial and social phenotypes in an avian scavenger
Journal of Animal Ecology, EarlyView.A method is applied to distinguish interaction rates that would be expected given animals' movements from those that exceed expected values due to incidental contact. The relationship between space use and both observed and non‐incidental social network position varies between social situations.

Journal of Mathematics, 2022 In this study, a predator-prey model with the Allee effect and fear effect is established. We use the comparison principle to prove boundedness. The zero equilibrium point and nonzero equilibrium point of the model are calculated, and the local stability

Quid Pro Quo? Private Information Flows in Shareholder Activism: Evidence from Mutual Fund Families
Journal of Accounting Research, EarlyView.ABSTRACT This paper hypothesizes that information flows from target firms to large shareholders during activist campaigns and that these flows have governance consequences. Focusing on actively managed mutual fund families, we find that informed trading by large‐holding fund families increases during activist campaigns relative to smaller‐holding fund ...

Insect Science, EarlyView.Stable flies preferentially oviposit on sites offering conspecific eggs with egg‐derived airborne semiochemicals. Egg‐borne bacterial symbionts, and Serratia marcescens in particular, produce odorants which attract gravid female flies and elicit oviposition.
