We consider a stochastic individual-based model for the evolution of a haploid, asexually reproducing population. The space of possible traits is given by the vertices of a (possibly directed) finite graph $G=(V,E)$. The evolution of the population is driven by births, deaths, competition, and mutations along the edges of $G$. We are interested in the large population limit under a mutation rate $\mu_K$ given by a negative power of the carrying capacity $K$ of the system: $\mu_K=K^{-1/\alpha…

A general multi-scale description of metastable adaptive motion across fitness valleys

This work develops the framework of a meta graph that is constituted of ESCs and possible metastable transitions between those, and proves the convergence of the population process to a Markov jump process visiting only ESCs of sufficiently high stability.

Filling the gap between individual-based evolutionary models and Hamilton-Jacobi equations

We consider a stochastic model for the evolution of a discrete population structured by a trait with values on a finite grid of the torus, and with mutation and selection. Traits are vertically



From adaptive dynamics to adaptive walks

This work considers an asexually reproducing population on a finite type space whose evolution is driven by exponential birth, death and competition rates, as well as the possibility of mutation at a birth event, and modelled as a measure-valued Markov process.

A rigorous model study of the adaptive dynamics of Mendelian diploids

It is proved under the usual smoothness assumptions, starting from a stochastic birth and death process model, that, when advantageous mutations are rare and mutational steps are not too large, the population behaves on the mutational time scale as a jump process moving between homozygous states (the trait substitution sequence of the adaptive dynamics literature).

Survival of a recessive allele in a Mendelian diploid model

It is proved that, under the assumption that a dominant allele is also the fittest one, the recessive allele survives for a time of order at least K1/4-α, where K is the size of the population and α >0$$α>0.

On time scales and quasi-stationary distributions for multitype birth-and-death processes

The existence of a quasi-stationary distribution (qsd) is proved, establishing a bound for the total variation distance between the process conditioned to non-extinction before time $t$ and the qsd, which is exponentially small in $t$, for $t\gg \log K$.

Crossing a fitness valley as a metastable transition in a stochastic population model

This work focuses on the limit of large population and rare mutations at several speeds, and chooses parameters such that the induced fitness landscape exhibits a valley: mutant individuals with negative fitness have to be created in order for the population to reach a trait with positive fitness.

Polymorphic evolution sequence and evolutionary branching

It is proved that under a good combination of these two scales, the population process is approximated in the long time scale of mutations by a Markov pure jump process describing the successive trait equilibria of the population.

Stochastic analysis of emergence of evolutionary cyclic behavior in population dynamics with transfer

The goal is to analyze the trade-off between natural evolution to higher birth rates and transfer, which drives the population towards lower birth rates, and implies that negligible sub-populations may have a strong contribution to evolution.

The Effect of Recurrent Mutations on Genetic Diversity in a Large Population of Varying Size

The genetic signature left by a selective sweep induced by recurrent mutations at a given locus is distinguished from an allele A$A$ to an allele a$a$, depending on the mutation frequency, to distinguish three possible scales for the mutation probability per reproductive event.

A stochastic model for speciation by mating preferences

A stochastic model of population where individuals, with type a or A, are equivalent from ecological, demographical and spatial points of view, and differ only by their mating preference, showing that mating preferences by themselves, even if they are very small, are enough to entail reproductive isolation between patches.
