Optimal harvesting modeling is a matter of great importance for the sustainability of the eco-
system. It is customary to consider the population dynamics in a continuous frame of time. In …

In the recent years much importance has been laid on the role of uncertainty (fuzzy, interval
etc.) in mathematical biology. In this paper we tried to study on the quota harvesting model in …

Having much attention in the past few years, uncertainty (fuzzy, interval etc.,) play important
role in mathematical biology. In this paper we study a proportional harvesting model in fuzzy …

In this paper, a novel concept of fuzzy prey–predator model is introduced by considering the
imprecise nature of the biological parameters. We consider the imprecise biological …

Presently population dynamics is an intercoagulating subject that projects the mathematical
representation, treatment and modelling of population enhancement through various …

This paper deals with a prey–predator model in which both the species are infected by some
toxicants which are released by some other species or source with fuzzy biological …

The objective of this paper is to investigate the dynamic behaviors of a prey-predator model
incorporating the effect of toxic substances with prey refuge under imprecise parameters. We …

To understand roles of fuzzy biological parameters, in this paper, we propose a fuzzy
predator–prey harvesting model that incorporates both the effects of prey refuge and …

Considering that species in nature are affected by the complexity of the ecosystem,
biological parameters present certain inaccuracy or uncertainty. Different species exhibit …

The study fuzzy difference equation becomes very important as huge numbers of real-life
problems in the field of engineering; ecology social science, etc. can be mathematically …
