Dissemination at Physics of Life 2023 (Harrogate, England)
In April 2023, Mauro Mobilia and Matthew Asker attended the conference Physics of Life 2023. Mauro gave an invited talk and Matthew presented a poster. Matthew’s poster can be viewed here.
APS March meeting 2023: Effects of a periodically changing environment on a predator prey ecology
Abstract: We study the 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 carrying capacity) that represent finite food resources for … Read more
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
Evolutionary Dynamics in a Varying Environment: Continuous versus Discrete Noise
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
Lotka-Volterra predator-prey model with periodically varying carrying capacity
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
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
