This paper deals with a delayed ratio-dependent functional response predator-prey model
with a threshold harvesting policy. We study the equilibria of the system before and after the …

The present paper deals with a non-linear mathematical model of three species food chain
community having ratio-dependent functional response, where all the species are subjected …

A predator-prey system with Holling type II functional response and a time lag is described
by a delayed differential-algebra system and the local asymptotic stability and Hopf …

A delayed Leslie-Gower predator-prey model with continuous threshold prey harvesting is
studied. Existence and local stability of the positive equilibrium of the system with or without …

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 …

Interactions in the ecosystem are inseparable from predator-prey interactions. Population
model of two species that the predator interacts with its prey for its survival has been …

In this paper we study the properties of the Hopf bifurcations obtained for a delayed predator-
prey model with continuous prey harvesting. Considering delay as a parameter, we …

This paper deals with a ratio-dependent functional response predator-prey model, with a
threshold harvesting in the predator equation. We study the equilibria of the system before …

In studying some biological problems, the descriptive features of biological systems are
delivered by differential equations which can be studied quantitatively by both analytical and …
