Aggregation as a Double-Edged Sword: Fear, Allee Effects, and Finite-Time Collapse
Kwadwo Antwi-Fordjour, Eric M. Takyi
Prey aggregation is widely regarded as a defense against predation, yet we show that in disease-structured populations subject to predator-induced fear and demographic Allee thresh…
Dynamics of Diseased-Impacted Prey Populations: Defense and Allee Effect Mechanisms
Kwadwo Antwi-Fordjour, Zachary Overton, Dylan Lee
This study introduces an innovative framework for merging ecological and epidemiological modeling via the formulation of a sophisticated predator-prey model that addresses the intr…
Dual fear phenomenon in an eco-epidemiological model with prey aggregation
Kwadwo Antwi-Fordjour, Sarah P. Westmoreland, Kendall H. Bearden
This study presents a thorough analysis of an eco-epidemiological model that integrates infectious diseases in prey, prey aggregation, and the dual fear effect induced by predators…
Comment on predator-prey dynamical behavior and stability with square root functional response
Kendall H. Bearden, Kwadwo Antwi-Fordjour
In this research, we revisit the paper by Pal et al. [Int. J. Appl. Comput. Math (2017) 3:1833-1845] and comment on the claim that global stability of the interior equilibrium poin…
Exploring unique dynamics in a predator-prey model with generalist predator and group defence in prey
Vaibhava Srivastava, Kwadwo Antwi-Fordjour, Rana D. Parshad
In the current manuscript, we consider a predator-prey model where the predator is modeled as a generalist using a modified Leslie-Gower scheme, and the prey exhibits group defence…
Additional food causes predator "explosion" -- unless the predators compete
Rana D. Parshad, Sureni Wickramsooriya, Kwadwo Antwi-Fordjour +1
The literature posits that an introduced predator population, is able to drive it's target pest population extinct, if supplemented with high quality additional food of quantity $ξ…
Fear-driven extinction and (de)stabilization in a predator-prey model incorporating prey herd behavior and mutual interference
Kwadwo Antwi-Fordjour, Rana D. Parshad, Hannah E. Thompson +1
A deterministic two-species predator-prey model with prey herd behavior is considered incorporating mutual interference and the effect of fear. We provide guidelines to the dynamic…
Some "counterintuitive" results in two species competition
Rana D. Parshad, Kwadwo Antwi-Fordjour, Eric M. Takyi
We investigate the classical two species ODE and PDE Lotka-Volterra competition models, where one of the competitors could potentially go extinct in finite time. We show that in th…
Dynamics of a predator-prey model with generalized Holling type functional response and mutual interference
Kwadwo Antwi-Fordjour, Rana D. Parshad, Matthew A. Beauregard
Mutual interference and prey refuge are important drivers of predator-prey dynamics. The "exponent" or degree of mutual interference has been under much debate in theoretical ecolo…
The "higher" status language does not always win: The fall of English in India and the rise of Hindi
Kushani De Silva, Rana D. Parshad, Aladeen Basheer +3
Classical language dynamics explains language shift as a process in which speakers adopt a higher status language in lieu of a lower status language. This is well documented with E…
Global analysis of the shadow Gierer-Meinhardt system with general linear boundary conditions in a random environment
Kwadwo Antwi-Fordjour, Seonguk Kim, Marius Nkashama
The global analysis of the shadow Gierer-Meinhardt system with multiplicative white noise and general linear boundary conditions is investigated in this paper. For this reaction-di…
