Modeling the effect of toxicant on the deformity in a subclass of a biological species

Abstract: In this paper, a nonlinear mathematical model to study the effect of a toxicant on a biological population is proposed and analyzed. We have taken the case in which some members of a biological population get severely affected by the toxicant and show abnormal symptoms, like deformity, fecundity, necrosis, etc. It has been assumed that the toxicant is produced by the population itself. This model can be applied to the human population which creates pollution and affects itself. The analysis of the model sugges… Show more

“…They have proposed and analyzed mathematical models by considering different cases, such as effect of a single toxicant or more than one toxicant on biological species, allelopathy case, deformity in a subclass of species, etc. (Freedman and Shukla 1991;Shukla and Agrawal 1999;Shukla et al 2003;Agrawal and Shukla 2012;Kumar et al 2016), to provide important insights for the effect of toxicants on biological species. In particular, Freedman and Shukla (1991) have studied the effect a single toxicant on a species with a consideration that toxicant affected on the growth rate and decreasing the carrying capacity of the environment.…”

“…Here, it is assumed that toxicant is emitted in the environment from some external source. Further, understand the case of deformity after-effect of a toxicant in more meaningful manner, Kumar et al (2016) proposed and analyzed a model with an assumption that toxicant emitted by biological species itself. They have shown, toxicant decreased the total population density and a subclass of species suffers from deformity.…”

“…The research works have been carried out for different cases such as effect of a single toxicant, more than one toxicant, on a biological species or two biological species with a competition of thrives in the same environment etc. Further, a highly important phenomenon that is after-effect of toxicants a subclass of biological species shows deformity, was studied ( [1], [5]). Agrawal et al [1] proposed a model to study the effect of a single toxicant emitted from some external sources, on a biological species in which a subclass of biological species having abnormal symptoms and not capable in reproduction.…”
