Over the last two decades, mitochondrial DNA (mtDNA) sequence data, as well as analyses
of nuclear DNA based on the multispecies coalescent model, have increasingly been used …

Species delimitation requires a broad assessment of population-level variation using
multiple lines of evidence, a process known as integrative taxonomy. More specifically …

As genomic data proliferates, the prevalence of post-speciation gene flow is making species
boundaries and relationships increasingly ambiguous. Although current approaches …

Complex speciation, involving rapid divergence and multiple bouts of post-divergence gene
flow, can obfuscate phylogenetic relationships and species limits. In North America, cases of …

Chromosome rearrangements can result in the rapid evolution of hybrid incompatibilities.
Robertsonian fusions, particularly those with monobrachial homology, can drive …

The application of high-throughput, short-read sequencing to degraded DNA has greatly
increased the feasibility of generating genomic data from historical museum specimens …

Most species and therefore most hybrid zones have historically been defined using
phenotypic characters. However, both speciation and hybridization can occur with negligible …

Approximately 100 years ago, unregulated harvest nearly eliminated white‐tailed deer
(Odocoileus virginianus) from eastern North America, which subsequently served to catalyze …

Coca is the natural source of cocaine as well as a sacred and medicinal plant farmed by
South American Amerindians and mestizos. The coca crop comprises four closely related …

Species delimitation in the genomic era has focused predominantly on the application of
multiple analytical methodologies to a single massive parallel sequencing (MPS) data set …
