The present paper discusses the dynamics and optimal harvesting of an intraguild prey-
predator fishery model by incorporating the nonlinear Michaelis-Menten type of harvesting in …

Natural resources and its enrichment activities are often being associated with the
paradoxical effects in ecology such as in predator–prey and fishery models. Several studies …

We first present a predator-prey model for two species and then extend the model to three
species where the two predator species engage in mutualistic predation. Constant effort …

Latterly, variable carrying capacity in the predator–prey population models has been widely
studied to provide more realistic understanding about population dynamics. In the present …

This work deals with a prey–predator model in an environment where the carrying capacities
are assumed to be variable with time and one species feeds upon the other. Independent …

An intraguild predator–prey model with a carrying capacity proportional to the biotic
resource, is generalized by introducing a Holling type II functional response. The longtime …

Intraguild predation, representing a true combination of predation and competition between
two species that rely on a common resource, is of foremost importance in many natural …

Release of toxic substances in water bodies from various sources is a major threat to
ecologically most vulnerable aquatic food-chain. Again, planktons which hold the whole …

The aim of this work is to analyze the dynamics of intraguild predation model with ratio-
dependent functional response and time-delay. We examine the conditions for local stability …

In this paper, we consider a stochastic predator-prey model with general functional
response, which is perturbed by nonlinear Lévy jumps. Firstly, We show that this model has …
