A hub for all research pertaining to Eco-Evolutionary Dynamics of Fluctuating Populations
Authors: Matthew Asker, Lluís Hernández-Navarro, Alastair M. Rucklidge, Mauro Mobilia Abstract: Microbial populations generally evolve in volatile environments, under conditions fluctuating between harsh and mild, e.g. as the result of sudden changes in toxin concentration … Read more
Authors: Lluís Hernández-Navarro, Matthew Asker, Alastair M. Rucklidge, Mauro Mobilia Abstract: There is a pressing need to better understand how microbial populations respond to antimicrobial drugs, and to find mechanisms to possibly eradicate antimicrobial-resistant cells. … Read more
Abstract: A stochastic evolutionary dynamics of two strategies given by 2 × 2 matrix games is studied in finite populations. We focus on stochastic properties of fixation: how a strategy represented by a single individual … Read more
Abstract: The functioning of animal as well as human societies fundamentally relies on cooperation. Yet, defection is often favorable for the selfish individual, and social dilemmas arise. Selection by individuals’ fitness, usually the basic driving … Read more
Abstract: Policies aimed at alleviating the growing problem of drug-resistant pathogens by restricting antimicrobial usage implicitly assume that resistance reduces the Darwinian fitness of pathogens in the absence of drugs. While fitness costs have been … Read more
Abstract: Traditionally, frequency dependent evolutionary dynamics is described by deterministic replicator dynamics assuming implicitly infinite population sizes. Only recently have stochastic processes been introduced to study evolutionary dynamics in finite populations. However, the relationship between … Read more
Authors: Ami Taitelbaum, Robert West, Mauro Mobilia, Michael Assaf Abstract: Environmental variations can significantly influence how populations compete for resources, and hence shape their evolution. Here, we study population dynamics subject to a fluctuating environment … Read more
Authors: Mohamed Swailem, Uwe C. Täuber Abstract: We study the stochastic spatial Lotka-Volterra model for predator-prey competition subject to a periodically varying carrying capacity. The Lotka-Volterra model with on-site lattice occupation restrictions (i.e., finite local … Read more
Abstract: The environment in which a population evolves can have a crucial impact on selection. We study evolutionary dynamics in finite populations of fixed size in a changing environment. The population dynamics are driven by … Read more

Here, we study the … Read more
