Unraveling the temporal dependence of ecological interaction measures
Javier Aguilar, Samir Suweis, Amos Maritan +1
Identifying the network of species interactions is a fundamental step toward understanding ecosystem stability and biodiversity. However, the interpretability of empirical interact…
Habitat heterogeneity and dispersal network structure as drivers of metacommunity dynamics
Davide Bernardi, Alice Doimo, Giorgio Nicoletti +5
Spatial structure and species interactions jointly shape the dynamics and biodiversity of ecological systems, yet most theoretical models either neglect spatial heterogeneity or sa…
Dispersal diversity buffers species vulnerability to local extinction
Davide Bernardi, Giorgio Nicoletti, Prajwal Padmanabha +5
Predicting species persistence within ecological communities is a fundamental challenge for both empirical and theoretical ecology. Existing methods span from mechanistic models, w…
Pathogen diversity emerging from coevolutionary dynamics in interconnected systems
Davide Zanchetta, Vittoria Bettio, Sandro Azaele +1
The spread of infectious disease and the evolution of antigenically distinct strains are often modeled separately, despite strong feedbacks mediated by host immune memory and heter…
Will a time-varying complex system be stable?
Francesco Ferraro, Christian Grilletta, Amos Maritan +2
Randomly-assembled dynamical systems are theoretically predicted to be unstable upon crossing a critical threshold of complexity, as first shown by May. Yet, empirical complex syst…
Pulse desynchronization of neural populations by targeting the centroid of the limit cycle in phase space
Ramón Guevara, Marco Zenari, Giorgio Nicoletti +4
The synchronized activity of neuronal populations can lead to pathological over-synchronization in conditions such as epilepsy and Parkinson disease. Such states can be desynchroni…
