Stochastic trade-offs and the emergence of diversification in E. coli evolution experiments
Roberto Corral López, Samir Suweis, Sandro Azaele +1
Laboratory experiments with bacterial colonies, under well-controlled conditions often lead to evolutionary diversification, where at least two ecotypes emerge from an initially mo…
Generalized Lotka-Volterra Systems with Time Correlated Stochastic Interactions
Samir Suweis, Francesco Ferraro, Christian Grilletta +2
In this work, we explore the dynamics of species abundances within ecological communities using the Generalized Lotka-Volterra (GLV) model. At variance with previous approaches, we…
Effect of delay on the emergent stability patterns in Generalized Lotka-Volterra ecological dynamics
Meghdad Saeedian, Emanuele Pigani, Amos Maritan +2
Understanding the conditions of feasibility and stability in ecological systems is a major challenge in theoretical ecology. The seminal work of May in 1972 and recent developments…
Effective Resource-Competition Model for Species Coexistence
Deepak Gupta, Stefano Garlaschi, Samir Suweis +2
Local coexistence of species in large ecosystems is traditionally explained within the broad framework of niche theory. However, its rationale hardly justifies rich biodiversity ob…
How neutral and niche forces contribute to speciation processes?
Niccolo Anceschi, Jorge Hidalgo, Tommaso Bellini +2
The evolutionary and ecological processes behind the origin of species are among the most fundamental problems in biology. In fact, many theoretical hypothesis on different type of…
Reconciling cooperation, biodiversity and stability in complex ecological communities
Chengyi Tu, Samir Suweis, Jacopo Grillib +2
Empirical observations show that ecological communities can have a huge number of coexisting species, also with few or limited number of resources. These ecosystems are characteriz…
