Dynamical robustness of network of oscillators

S Majhi, B Rakshit, A Sharma, J Kurths, D Ghosh - Physics Reports, 2024 - Elsevier
Most complex systems are nonlinear, relying on emergent behavior resulting from many
interacting subsystems, which are often characterized by oscillatory dynamics. Having …

Complex evolutionary dynamics due to punishment and free space in ecological multigames

SN Chowdhury, S Kundu, M Perc… - Proceedings of the …, 2021 - royalsocietypublishing.org
The concurrence of ecological and evolutionary processes often arises as an integral part of
various biological and social systems. We here study eco-evolutionary dynamics by …

Eco-evolutionary dynamics of cooperation in the presence of policing

SN Chowdhury, S Kundu, J Banerjee, M Perc… - Journal of Theoretical …, 2021 - Elsevier
Ecology and evolution are inherently linked, and studying a mathematical model that

Desynchrony induced by higher-order interactions in triplex metapopulations

PK Pal, MS Anwar, D Ghosh - Physical Review E, 2023 - APS
In a predator-prey metapopulation, two traits are adversely related: synchronization and
persistence. A decrease in synchrony apparently leads to an increase in persistence and …

Diffusion induced spiral wave chimeras in ecological system

S Kundu, S Majhi, P Muruganandam… - The European Physical …, 2018 - Springer
The peculiar phenomenon of chimera state corresponds to the exceptional spatial
concurrence of coherent and incoherent dynamical behaviors appearing in networks of …

An analysis of threats, strategies, and opportunities for African rhinoceros conservation

A Chanyandura, VK Muposhi, E Gandiwa… - Ecology and …, 2021 - Wiley Online Library
The complexity and magnitude of threats to black (Diceros bicornis) and white
(Ceratotherium simum) rhinoceros conservation in Africa have triggered global concerns …

Network topology and patch connectivity affect dynamics in experimental and model metapopulations

PA Arancibia, PJ Morin - Journal of Animal Ecology, 2022 - Wiley Online Library
Biological populations are rarely isolated in space and instead interact with others via
dispersal in metapopulations. Theory predicts that network connectivity patterns can have …

Ecological resilience in a circular world: Mutation and extinction in five-species ecosystems

K Viswanathan, A Wilson, S Bhattacharyya… - Chaos, Solitons & …, 2024 - Elsevier

can be induced by various factors such as errors in DNA replication and exposure to …

Chemical synaptic multiplexing enhances rhythmicity in neuronal networks

S Kundu, S Majhi, D Ghosh - Nonlinear Dynamics, 2019 - Springer
Real-world networks are rarely isolated; rather, they constitute a large number of elements
interacting through complex topologies and oscillation is essential for their proper …
