A Factor Graph Approach to Scalable Multi-Output Gaussian Process Regression
Wouter W. L. Nuijten, Esther G. van Pelt, Albert Podusenko +2
Multi-output Gaussian process regression scales cubically in the number of observations times outputs, and dense kernel-matrix methods need bespoke handling whenever different outp…
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…
Finite size scaling of survival statistics in metapopulation models
Alice Doimo, Giorgio Nicoletti, Davide Bernardi +1
Spatial metapopulation models are fundamental to theoretical ecology, enabling to study how landscape structure influences global species dynamics. Traditional models, including re…
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…
