Hybridization is increasingly recognized as a creative evolutionary force contributing to
adaptation and speciation. Homoploid hybrid speciation—the process in which hybridization …

The high incidence of hybridization in waterfowl (ducks, geese and swans) makes this bird
group an excellent study system to answer questions related to the evolution and …

The study of genetic exchange resulting from natural hybridization, horizontal gene transfer,
and viral recombination has long been marked by controversy between researchers holding …

The translocation of individuals around the world is leading to rising incidences of
anthropogenic hybridization, particularly between domestic and wild congeners. We apply a …

Along with manipulating habitat, the direct release of domesticated individuals into the wild
is a practice used worldwide to augment wildlife populations. We test between possible …

Speciation is a continuous and dynamic process, and studying organisms during the early
stages of this process can aid in identifying speciation mechanisms. The mallard (Anas …

Recently evolved species typically share genetic variation across their genomes due to
incomplete lineage sorting and/or ongoing gene flow. Given only subtle allele frequency …

Generally, genotypes and phenotypes are expected to be spatially congruent; however, in
widespread species complexes with few barriers to dispersal, multiple contact zones, and …

Resolving evolutionary relationships and establishing population structure depends on
molecular diagnosability that is often limited for closely related taxa. Here, we use 3,200 …
