Numerical Study of Interaction Network Structures in Competitive Ecosystems
David A. Kessler, Nadav M. Shnerb
We present a numerical analysis of local community assembly through weak migration from a regional species pool. At equilibrium, the local community consists of a subset ("clique")…
Dominance to egalitarian transition in diverse communities
David A. Kessler, Nadav M. Shnerb
Diverse communities of competing species are generally characterized by substantial niche overlap and strongly stochastic dynamics. Abundance fluctuations are proportional to popul…
Extinction time distributions of populations and genotypes
David Kessler, Nadav M. Shnerb
In the long run, the eventual extinction of any biological population is an inevitable outcome. While extensive research has focused on the average time it takes for a population t…
Stability and Fluctuations in Complex Ecological Systems
Eric Forgoston, Sarah Day, Peter C. de Ruiter +24
From 08-12 August, 2022, 32 individuals participated in a workshop, Stability and Fluctuations in Complex Ecological Systems, at the Lorentz Center, located in Leiden, The Netherla…
Communities as cliques
Yael Fried, David A. Kessler, Nadav M. Shnerb
High-diversity assemblages are very common in nature, and yet the factors allowing for the maintenance of biodiversity remain obscure. The competitive exclusion principle and May's…
Neutral dynamics with environmental noise: age-size statistics and species lifetimes
David Kessler, Samir Suweis, Marco Formentin +1
Neutral dynamics, where taxa are assumed to be demographically equivalent and their abundance is governed solely by the stochasticity of the underlying birth-death process, has pro…
