A multiscale theory based on metabolic scaling connects forest dynamics to tree-size distributions
Christian Grilletta, Tommaso Anfodillo, Gaia Pasqualotto +4
Scaling relations linking species size, abundance, and resource availability are among the most robust empirical regularities in ecology. However, a mechanistic explanation for how…
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…
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…
Topological Origin of the Diversity of Timescales in Recurrent Neural Circuits
Marco Zenari, Luca Taffarello, Luca Mazzucato +2
Structural and functional heterogeneity are hallmarks of cortical circuits, from broad degree distributions in the mouse connectome to diverse intrinsic neuronal timescales. Yet a…
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…
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…
Microbiomes Through The Looking Glass: Linking species interactions to dysbiosis through a disordered Lotka-Volterra framework
Jacopo Pasqualini, Amos Maritan, Andrea Rinaldo +4
The rapid advancement of environmental sequencing technologies, such as metagenomics, has significantly enhanced our ability to study microbial communities. The eubiotic compositio…
Exact solution of Dynamical Mean-Field Theory for a linear system with annealed disorder
Francesco Ferraro, Christian Grilletta, Amos Maritan +2
We investigate a disordered multi-dimensional linear system in which the interaction parameters vary stochastically in time with defined temporal correlations. We refer to this typ…
Spatially disordered environments stabilize competitive metacommunities
Prajwal Padmanabha, Giorgio Nicoletti, Davide Bernardi +4
Metapopulation models have been instrumental in demonstrating the ecological impact of landscape structure on the survival of a focal species in complex environments. However, exte…
Growth or Reproduction: Emergence of an Evolutionary Optimal Strategy
Jacopo Grilli, Samir Suweis, Amos Maritan
Modern ecology has re-emphasized the need for a quantitative understanding of the original 'survival of the fittest theme' based on analyzis of the intricate trade-offs between com…
