When evolution realizes large deviations of fitness: from speciation to dynamical phase transitions
Sara Dal Cengio, Quentin Laurenceau, Vivien Lecomte +2
We explore the connection between evolution and large-deviation theory. To do so, we study evolutionary dynamics in which individuals experience mutations, reproduction, and select…
Dynamics of Two Species with Density-Dependent Interactions and Application to Mutualism
Chloë Mian, Sylvain Billiard, Violaine Llaurens +1
Ecological interactions shape the dynamics of natural populations in the wild. Density-dependent processes are widespread and may change the respective effects of populations on on…
A stochastic individual based model for the growth of a stand of Japanese knotweed including mowing as a management technique
François Lavallée, Charline Smadi, Isabelle Alvarez +4
Invasive alien species are a growing threat for environment and health. They also have a major economic impact, as they can damage many infrastructures. The Japanese knotweed (Fall…
Looking for the right mate in diploid species: how dominance relationships affect population differentiation in sexual trait?
Charline Smadi, Helene Leman, Violaine Llaurens
Divergence between populations for a given trait can be driven by natural or sexual selection, interacting with migration behaviour. Mating preference for different phenotypes can…
Stochastic dynamics of three competing clones: Conditions and times for invasion, coexistence and fixation
Sylvain Billiard, Charline Smadi
In large clonal populations, several clones generally compete which results in complex evolutionary and ecological dynamics: experiments show successive selective sweeps of favorab…
A stochastic model for speciation by mating preferences
Camille Coron, Manon Costa, Hélène Leman +1
Mechanisms leading to speciation are a major focus in evolutionary biology. In this paper, we present and study a stochastic model of population where individuals, with type a or A…
