Fixation of Strategies for an Evolutionary Game in Finite Populations
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
The edge of neutral evolution in social dilemmas
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
Adaptation to the fitness costs of antibiotic resistance in Escherichia coli
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
Coevolutionary Dynamics: From Finite to Infinite Populations
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
Fixation in finite populations evolving in fluctuating environments
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
Dissemination at UMCW06 2022 (Cambridge, England)
In October 2022, Mauro Mobilia, Lluís Hernandez-Navarro, Matthew Asker, and Said Munoz Monterro attended the workshop UMCW06: Microbial communities: current approaches and open challenges. Lluís gave a contributed talk, and Matthew and Said presented posters. … Read more
Feedback between Population and Evolutionary Dynamics Determines the Fate of Social Microbial Populations
Abstract: The evolutionary spread of cheater strategies can destabilize populations engaging in social cooperative behaviors, thus demonstrating that evolutionary changes can have profound implications for population dynamics. At the same time, the relative fitness of … Read more

Descriptive & Normative Models of Collective Behaviour workshop
This workshop will bring together recent developments in collective behaviour from theoretical and empirical research. We hope to explore common ground between data-driven approaches utilising sensor technology and statistical analysis, and the latest mathematical & … Read more
