A common method of minimizing errors in large DNA sequence data sets is to drop variable
sites with a minor allele frequency (MAF) below some specified threshold. Although …

Real geography is continuous, but standard models in population genetics are based on
discrete, well-mixed populations. As a result, many methods of analyzing genetic data assume …

Most organisms are more closely related to nearby than distant members of their species,
creating spatial autocorrelations in genetic data. This allows us to predict the location of origin …

Dimensionality reduction is a common tool for visualization and inference of population
structure from genotypes, but popular methods either return too many dimensions for easy …

During range expansions, species can experience rapid population growth if changes in
climate or interspecific interactions remove limits on growth rates in novel habitats. Here I …

Mosquito control remains a central pillar of efforts to reduce malaria burden in sub-Saharan
Africa. However, insecticide resistance is entrenched in malaria vector populations, and …

Levels of genetic differentiation vary widely along the genomes of recently diverged species.
What processes cause this variation? Here, I analyze geographic population structure and …

In the painted bunting (Passerina ciris), a North American songbird, populations on the Atlantic
coast and interior southern United States are known to be allopatric during the breeding …

Migratory species that alternate between sympatry and allopatry over the course of an annual
cycle are promising subjects for studies seeking to understand the process of speciation in …

The family Vireonidae represents one of the most widespread and well-known New World
avian radiations, but a robust species-level phylogeny of the group is lacking. Here, we infer a …
