In this study, we introduce a novel tri-trophic food chain model that integrates cannibalism among basal prey and harvesting behaviors in the top predator, aiming to understand ecosystem dynamics comprehensively. Objectives encompass assessing system

In this paper, we study stabilization problem on a model for covid-19 by using Routh-Hurwitz criterion and Gershgorin circles. Using Routh-Hurwitz criterion, we prove the necessity of unstability and stability conditions for the model that we extend

In this paper, we analyzed the local stability of three species in two fractional tritrophic systems, with Caputo's fractional derivative and Holling type Ⅱ and Ⅲ functional responses, when the prey density has a linear growth. To begin, we obtai

Models involving four species with prey refuge and type I responses have been studied with recommendations on their extension to include either type II or type III responses. However, models with Holling type II responses are de-stabilizing according
