The dynamics of a ratio-dependent predator-prey model with two different non-constant
harvesting functions depending on the predator population is studied. Equilibria and …

The dynamics of constant harvesting of a single species has been studied extensively within
the framework of ratio-dependent predator-prey models. In this work, we investigate the …

The dynamics of a predator–prey model with continuous threshold prey harvesting and prey
refuge is studied. One central question is how harvesting and refuge could directly affect the …

The global behaviour of a class of predator-prey systems, modelled by a pair of non-linear
ordinary differential equations, under constant rate harvesting and/or stocking of both …

We analyze the global behavior of a predator-prey system, modelled by a pair of non-linear
ordinary differential equations, under constant-rate prey harvesting. By methods analogous …

This paper deals with the problem of a ratio-dependent prey-predator model with combined
harvesting. The existence of steady states and their stability are studied using eigenvalue …

The objective of this paper is to study systematically the dynamical properties of a ratio-
dependent predator–prey model with nonzero constant rate predator harvesting. It is shown …

We study the local stability of ratio-dependent predator–prey models with nonconstant
predator harvesting rates. We provide more general conditions on the parameters involved …

A ratio-dependent predator–prey model with time lag for predator is proposed and analyzed.
Mathematical analyses of the model equations with regard to boundedness of solutions …

A ratio-dependent predator-prey model with stage structure for the prey is proposed and
analyzed, which improves the assumption that each individual prey has the same ability to …
