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.

Scaling temperature‐dependent dispersal rates to metacommunity dynamics: An experimental test
Functional Ecology, EarlyView.Read the free Plain Language Summary for this article on the Journal blog. Abstract Changes in community structure under shifting thermal regimes depend on how both local population dynamics and regional dispersal respond to temperature. Processes underlying dispersal, such as movement speed and demographic density dependence, are constrained by ...

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 ...

Estimating Allee thresholds before they can be observed: polar bears as a case study.
, 2014 Allee effects are an important component in the population dynamics of numerous species. Accounting for these Allee effects in population viability analyses generally requires estimates of low-density population growth rates, but such data are ...

Multiple Allee effects and population management
Trends in Ecology & Evolution, 2007 Allee effects, strongly related to the extinction vulnerability of populations and gradually becoming acknowledged by both theoretically oriented and applied ecologists, have already been shown to have important roles in the dynamics of many populations.

Beyond Automation: AI and the Human Value of Sell‐Side Analysts
Journal of Accounting Research, EarlyView.ABSTRACT We examine how analysts’ information acquisition and processing differ when analysts have access to AI resources, focusing on investment banks’ AI investments. We propose and test a two‐step framework, which is informed by in‐depth interviews with analysts.
