Spatiotemporal dynamics of a predator-prey system with fear effect

K Sarkar, S Khajanchi - Journal of the Franklin Institute, 2023 - Elsevier
Recent field experiments on vertebrates show that though mere presence of a predator
causes a dramatic change in prey demography, the fear of predators increases the survival …

An eco-epidemiological model with the impact of fear

K Sarkar, S Khajanchi - Chaos: An Interdisciplinary Journal of …, 2022 - pubs.aip.org
In this study, we propose and analyze an eco-epidemiological model with disease in prey
