Public goods games in populations with fluctuating size
Journal Article
Many mathematical frameworks of evolutionary game dynamics assume that the total population size is constant and that selection affects only the relative frequency of strategies. Here,we consider evolutionary game dynamics in an extended Wright–Fisher...
A non-zero variance of Tajima’s estimator for two sequences even for infinitely many unlinked loci
Journal Article
The population-scaled mutation rate, θ, is informative on the effective population size and is thus widely used in population genetics. We show that for two sequences and n unlinked loci, the variance of Tajima’s estimator (ˆθ), which is the average...
A two-player iterated survival game
Journal Article
We describe an iterated game between two players, in which the payoff is to survive a number of steps. Expected payoffs are probabilities of survival. A key feature of the game is that individuals have to survive on their own if their partner dies. We...
Bayesian Estimation of Population Size Changes by Sampling Tajima’s Trees
Journal Article
The large state space of gene genealogies is a major hurdle for inference methods based on Kingman’s coalescent. Here, we present a new Bayesian approach for inferring past population sizes, which relies on a lower-resolution coalescent process that we...
Genomic architecture and introgression shape a butterfly radiation
Journal Article
We used 20 de novo genome assemblies to probe the speciation history and architecture of gene flow in rapidly radiating Heliconius butterflies. Our tests to distinguish incomplete lineage sorting from introgression indicate that gene flow has obscured...

Recurrent mutation in the ancestry of a rare variant
Journal Article
