Promotion of cooperation in deme-structured populations with growth-merging dynamics
Damien Ribière, Alia Abbara, Anne-Florence Bitbol
The spatial structure of populations may promote the emergence and maintenance of cooperation. Cooperation in the prisoner's dilemma is favored under specific update rules in evolu…
Environment heterogeneity creates fast amplifiers of natural selection in graph-structured populations
Cecilia Fruet, Arthur Alexandre, Alia Abbara +2
Complex spatial structure, with partially isolated subpopulations, and environment heterogeneity, such as gradients in nutrients, oxygen, and drugs, both shape the evolution of nat…
Bridging Wright-Fisher and Moran models
Arthur Alexandre, Alia Abbara, Cecilia Fruet +2
The Wright-Fisher model and the Moran model are both widely used in population genetics. They describe the time evolution of the frequency of an allele in a well-mixed population w…
Impact of phylogeny on the inference of functional sectors from protein sequence data
Nicola Dietler, Alia Abbara, Subham Choudhury +1
Statistical analysis of multiple sequence alignments of homologous proteins has revealed groups of coevolving amino acids called sectors. These groups of amino-acid sites feature c…
Mutant fate in spatially structured populations on graphs: connecting models to experiments
Alia Abbara, Lisa Pagani, Celia García-Pareja +1
In nature, most microbial populations have complex spatial structures that can affect their evolution. Evolutionary graph theory predicts that some spatial structures modelled by p…
Evolution of cooperation in deme-structured populations on graphs
Alix Moawad, Alia Abbara, Anne-Florence Bitbol
Understanding how cooperation can evolve in populations despite its cost to individual cooperators is an important challenge. Models of spatially structured populations with one in…
Frequent asymmetric migrations suppress natural selection in spatially structured populations
Alia Abbara, Anne-Florence Bitbol
Natural microbial populations often have complex spatial structures. This can impact their evolution, in particular the ability of mutants to take over. While mutant fixation proba…
