For a beneficial allele which enters a large unstructured population and eventually goes to fixation, it is known that the time to fixation is approximately $2\log(\alpha)/\alpha$ for a large selection coefficient $\alpha$. For a population that is distributed over finitely many colonies, with migration between these colonies, we detect various regimes of the migration rate $\mu$ for which the fixation times have different asymptotics as $\alpha \to \infty$. If $\mu$ is of order $\alpha$, the…

Phase-Type Distribution Approximations of the Waiting Time Until Coordinated Mutations Get Fixed in a Population
In this paper we study the waiting time until a number of coordinated mutations occur in a population that reproduces according to a continuous time Markov process of Moran type. It is assumed that
Stochastic Evolution of spatial populations: From configurations to genealogies and back
TLDR
The paper reviews the results obtained for spatial population models and the evolution of the genealogies of these populations during the last decade by the author and his coworkers and extends the classical model classes in new directions.
Evolution of highly fecund haploid populations.
Selective Sweeps
TLDR
These models, ranging from selective sweeps in a panmictic population of constant size to evolutionary traffic when simultaneous sweeps at multiple loci interfere, are discussed, and the important role of demography and population structure in data analysis is emphasized.
Adaptation in structured populations and fuzzy boundaries between hard and soft sweeps
TLDR
It is shown that sweeps maybe misclassified as either hard or soft, when the true time stage of a sweep and that implied by the model do not match, which can occur when hard sweeps, which are imported by migration into a new subpopulation, are falsely identified as soft.

A framework for estimating the fixation time of an advantageous allele in stepping‐stone models
TLDR
A framework for calculating the fixation time of a positively selected allele in a subdivided population, as a function of the number of demes present, the migration rate between them and the manner in which they are connected is laid out.
Fixation probability and time in subdivided populations.
TLDR
This article allows for an arbitrary distribution among demes of reproductive success, both beneficial and deleterious effects, and arbitrary dominance, and verified by simulation for a broad range of population structures, including the island model, the stepping-stone model, and a model with extinction and recolonization.

TLDR
The approach taken in this paper to the problem of finding the probabilities of fixation and times to fixation in a subdivided population is necessarily indirect and there is no way to solve the complete multi-dimensional diffusion equation and obtain the required quantities.
An approximate sampling formula under genetic hitchhiking
TLDR
A sampling formula is derived which shows that, with this order of accuracy, in a sample of fixed size there are at most two nonsingleton families of individuals which are identical by descent at the neutral locus from the beginning of the sweep.
The hitch-hiking effect of a favourable gene.
TLDR
If the selective coefficients at the linked locus are small compared to those at the substituted locus, it is shown that the probability of complete fixation at thelinked locus is approximately exp (— Nc), where c is the recombinant fraction and N the population size.

Random partitions approximating the coalescence of lineages during a selective sweep
TLDR
Two approximations for the selective sweep of a selective sweep are introduced, one of which is related to Kingman’s paintbox construction, replaces the coin flips by integer-valued random variables and leads to very accurate results.
Hitchhiking Effect of a Beneficial Mutation Spreading in a Subdivided Population
TLDR
The results indicate that the overall strength of genetic hitchhiking—the degree to which expected heterozygosity decreases—is diminished by population subdivision, mainly because opportunity for the breakdown of Hitchhiking by recombination increases as the spread of the beneficial mutation across demes is delayed when migration rate is much smaller than the strength of selection.
