This research analyzes the interaction of prey and carnivorous apex facultative scavengers in the existence of prey carrion biomass. Prey consists of vertebrate marine animals as the main food preferences for carnivorous apex facultative scavengers, which comprise fish, reptiles and marine mammals, whose carrion is also hunted and eaten. Apex facul...

Diagnostic and therapeutic purpose on human healthcare is moving to a trend of combined engineering principles and design concepts. It is therefore beneficial to refine the study on thermodynamic properties of bionanofluid towards a better state of diagnoses and treatments. This paper aims to determine the characteristics of a magnetohydrodynamics...

The current paper investigates a prey-predator-scavenger fishery model in which both prey and predator species release harmful toxins during predation interaction. The harvesting of scavengers is introduced due to their economic value and serves as one of the important protein sources for humans. Both predator and scavenger fish species consume pre...

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 predator. To our knowledge, there is limited literature working on Michaelis-Menten type of harvesting in a three species intraguild model with variable carrying capacity....

The present paper examines a predator-prey fishery system by taking into account the toxin released by the fish which can lead to polluted system. Both predator and prey fish species obey the logistic population growth with their respective environmental carrying capacities. In the proposed model, both fish species produce toxins that contribute to...

The present paper studies a predator–prey fishery model which incorporates the independent harvesting strategies and nonlinear impact of an anthropogenic toxicant. Both fish populations are harvested with different harvesting efforts, and the cases for the presence and non-presence of harvesting effort are discussed. The prey fish population is ass...

In this paper we consider a harvesting model of predator-prey fishery in which the prey is directly infected by some external toxic substances. The toxic infection is indirectly transmitted to the predator during the feeding process. The model is a modified version from the classic Lotka-Volterra predator-prey model. The stability and bifurcation a...

The present paper discusses a prey-predator fishery model where both species are subjected to harvesting effort. Both species release some toxic substances to each other. The prey species obeys the law of logistic growth. The model is a modified version from the classic Lotka-Volterra predator-prey model. The equilibria of the model are obtained an...
