Griffiths phase emerging from strong mutualistic disorder in high-dimensional interacting systems
Tommaso Jack Leonardi, Amos Maritan, Sandro Azaele
The majority of analysis of interacting systems is done for weak and well-balanced interactions, when in fact topology and rare event factors often result in strong and sign-biased…
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…
Generalized Lotka-Volterra systems with quenched random interactions and saturating nonlinear response
Marco Zenari, Francesco Ferraro, Sandro Azaele +2
The generalized Lotka-Volterra (GLV) equations with quenched random interactions have been extensively used to investigate the stability and dynamics of complex ecosystems. However…
Synchronization and chaos in complex ecological communities with delayed interactions
Francesco Ferraro, Christian Grilletta, Emanuele Pigani +3
Explaining the wide range of dynamics observed in ecological communities is challenging due to the large number of species involved, the complex network of interactions among them,…
A novel metric for species vulnerability and coexistence in spatially-extended ecosystems
Davide Bernardi, Giorgio Nicoletti, Prajwal Padmanabha +4
We develop a theoretical framework to understand the persistence and coexistence of competitive species in a spatially explicit metacommunity model with a heterogeneous dispersal k…
Generalized Lotka-Volterra model with sparse interactions: non-Gaussian effects and topological multiple-equilibria phase
Tommaso Tonolo, Maria Chiara Angelini, Sandro Azaele +2
We study the equilibrium phases of a generalized Lotka-Volterra model characterized by a species interaction matrix which is random, sparse and symmetric. Dynamical fluctuations ar…
Emergence of ecological structure and species rarity from fluctuating metabolic strategies
Davide Zanchetta, Deepak Gupta, Sofia Moschin +3
Ecosystems frequently display the coexistence of diverse species under resource competition, typically resulting in skewed distributions of rarity and abundance. A potential driver…
