The role of inducible defence in ecological models: Effects of nonlocal intraspecific competitions
Sangeeta Saha, Swadesh Pal, Roderick Melnik
Phenotypic plasticity is a key factor in driving the evolution of species in the predator-prey interaction. The natural environment is replete with phenotypic plasticity, which is…
Nonlocal cooperative behaviour, psychological effects, and collective decision-making: an exemplification with predator-prey models
Sangeeta Saha, Swadesh Pal, Roderick Melnik
In bio-social models, cooperative behaviour has evolved as an adaptive strategy, playing multi-functional roles. One of such roles in populations is to increase the success of surv…
Structural sensitivity of chaotic dynamics in Hastings-Powell's model
Indrajyoti Gaine, Swadesh Pal, Poulami Chatterjee +1
The classical Hastings-Powell model is well known to exhibit chaotic dynamics in a three-species food chain. Chaotic dynamics appear through period-doubling bifurcation of stable c…
Pattern alternations induced by nonlocal interactions
Swadesh Pal, Roderick Melnik, Malay Banerjee
Pattern formation is a visual understanding of the dynamics of complex systems. Patterns arise in many ways, such as the segmentation of animals, bacterial colonies during growth,…
Nonlocal Models in the Analysis of Brain Neurodegenerative Protein Dynamics with Application to Alzheimer's Disease
Swadesh Pal, Roderick Melnik
It is well known that today nearly one in six of the world's population has to deal with neurodegenerative disorders. While a number of medical devices have been developed for the…
