Effect of wind on prey-predator dynamics with group defense and additional food strategy
Anushree Hazra, Aniket Banerjee, Debaldev Jana
Wind plays a crucial role in changing prey defense strategy and predation efficiency. We develop and analyze a prey-predator model that incorporates wind driven environmental effec…
Self-diffusion Driven Pattern Formation in Prey-Predator System with Complex Habitat under Fear Effect
Debaldev Jana, Saikat Batabyal, M. Lakshmanan
In the present work, we explore the influence of habitat complexity on the activities of prey and predator of a spatio-temporal system by incorporating self diffusion. First we mod…
Interplay between reproduction and age selective harvesting delays of a single population non-autonomous system
N. S. N. V. K. Vyshnavi Devi, Debaldev Jana, M. Lakshmanan
This paper is concerned with an analysis of the dynamics of a non-autonomous, single population age based growth model with harvesting formulation. First, we derive sufficient cond…
Dynamics of a non-autonomous system with age-structured growth and harvesting of prey and mutually interfering predator with reliance on alternative food
N. S. N. V. K. Vyshnavi Devi, Debaldev Jana, M. Lakshmanan
We perform a detailed analysis of the behaviour of a non-autonomous prey-predator model where age based growth with age discriminatory harvesting in prey and predator's reliance up…
Complex dynamics generated by negative and positive feedback delays of a prey-predator system with prey refuge: Hopf bifurcation to Chaos
Debaldev Jana, R. Gopal, M. Lakshmanan
Various field and laboratory experiments show that prey refuge plays a significant role in the stability of prey-predator dynamics. On the other hand, theoretical studies show that…
