In this paper, we consider a diffusive predator-prey system with modified Holling-Tanner
functional response under homogeneous Neumann boundary condition. Dynamics of the …

The influence of time delay on harvesting policy of stage-structured species was
investigated using a non-linear mathematical model devised and tested in this work. A …

In this work, the system with two preys and one predator population is qualitatively analyzed.
The predator exhibits a Holling type I response to one prey and a Holling type IV response to …

In this thesis, several harvested fishery models using various types of harvesting strategies
including the common harvesting, independent harvesting and nonlinear Michaelis-Menten …

In this research, Euler method is applied to discretize a harvested predator prey model with
ratio-dependent response function and prey refuge. The existence and stability of fixed …

In this paper, the dynamic of prey predator model was discussed when the relationship
between them is functional response type III. In addition, when prey exposure to the disease …

In this paper, a non-linear harvesting of prey is considered in a prey-predator system. The
predator is considered to be of modified Leslie-Gower type. The effort is taken as dynamic …

This paper analyses a bionomic model of two competitive species in the presence of toxicity
with different harvesting efforts. An interesting dynamics in the first quadrant is analysed and …
