Alaska is a prime location to study avian speciation, divergence, and gene flow. The area of
Beringia, the region extending from the Russian Far East across the Bering Sea though …

In high-latitude species with high dispersal ability, such as long-distance migratory birds,
populations are often assumed to exhibit little genetic structure due to high gene flow or …

Fine-scale resolution of spatial genetic structure is important for understanding a species'
evolutionary history and contemporary genetic diversity. For high-latitude species with high …

Determining how genetic diversity is structured between populations that span the
divergence continuum from populations to biological species is key to understanding the …

Using a large, consistent set of loci shared by descent (orthologous) to study relationships
among taxa would revolutionize among-lineage comparisons of divergence and speciation …

The widespread application of high-throughput sequencing in studying evolutionary
processes and patterns of diversification has led to many important discoveries. However …

Understanding how gene flow affects population divergence and speciation remains
challenging. Differentiating one evolutionary process from another can be difficult because …

Evolutionary relationships among birds in Neoaves, the clade comprising the vast majority of
avian diversity, have vexed systematists due to the ancient, rapid radiation of numerous …

Understanding the factors driving phenotypic and genomic differentiation of insular
populations is of major interest to gain insight into the speciation process. Comparing …

Pelagic seabirds are highly mobile, reducing opportunities for population isolation that might
promote differentiation and speciation. At the same time, many seabirds are philopatric, and …
