Fixation of Strategies for an Evolutionary Game in Finite Populations

7th February 2023 by Matthew Asker

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

7th February 2023 by Matthew Asker

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

Coevolutionary Dynamics: From Finite to Infinite Populations

7th February 2023 by Matthew Asker

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

21st December 202221st December 2022 by Mauro Mobilia

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

Fixation in finite populations evolving in fluctuating environments

26th October 2022 by Matthew Asker

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

Resist or perish: Fate of a microbial population subjected to a periodic presence of antimicrobial

7th September 2022 by Mauro Mobilia

URL: https://doi.org/10.1371/journal.pcbi.1007798 Authors: Loïc Marrec and  Anne-Florence Bitbol Journal Ref.: PLoS Comput Biol 16(4): e1007798 (2020) Abstract: The evolution of antimicrobial resistance can be strongly affected by variations of antimicrobial concentration. Here, we study the … Read more

Feedback between Population and Evolutionary Dynamics Determines the Fate of Social Microbial Populations

8th August 2022 by Matthew Asker

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

Exclusion of the fittest predicts microbial community diversity in fluctuating environments

11th May 2022 by Matthew Asker

Abstract: Microorganisms live in environments that inevitably fluctuate between mild and harsh conditions. As harsh conditions may cause extinctions, the rate at which fluctuations occur can shape microbial communities and their diversity, but we still … Read more

Moran dynamics in spatially heterogeneous environments with periodic fitness distribution

11th May 2022 by Matthew Asker

Abstract: Local environmental interactions are a major factor in determining the success of a new mutant in structured populations. Spatial variations of concentration of a resource change the fitness of competing strategies locally and thus … Read more

Periodic temporal environmental variations induce coexistence in resource competition models

11th May 2022 by Matthew Asker

Abstract: Natural ecosystems, in particular on the microbial scale, are inhabited by a large number of species. The population size of each species is affected by interactions of individuals with each other and by spatial … Read more
