Hybridization is an evolutionary phenomenon that has fascinated biologists for centuries.
Prior to the advent of whole-genome sequencing, it was clear that hybridization had played …

Current approaches to biodiversity conservation are largely based on geographic areas,
ecosystems, ecological communities, and species, with less attention on genetic diversity …

Delimiting and naming biodiversity is a vital step toward wildlife conservation and research.
However, species delimitation must be consistent across biota so that the limited resources …

The current rate of species extinction is rapidly approaching unprecedented highs, and life
on Earth presently faces a sixth mass extinction event driven by anthropogenic activity …

The species concept is the cornerstone of biodiversity science, and any paradigm shift in the
delimitation of species affects many research fields. Many biologists now are embracing a …

Cryptic species could represent a substantial fraction of biodiversity. However, inconsistent
definitions and taxonomic treatment of cryptic species prevent informed estimates of their …

Speciation, the evolution of reproductive isolation among populations, is continuous,
complex, and involves multiple, interacting barriers. Until it is complete, the effects of this …

A primary roadblock to our understanding of speciation is that it usually occurs over a
timeframe that is too long to study from start to finish. The idea of a speciation continuum …

Phylogenomics has revealed the remarkable frequency with which introgression occurs
across the tree of life. These discoveries have been enabled by the rapid growth of methods …

Intrinsic postzygotic barriers can play an important and multifaceted role in speciation, but
their contribution is often thought to be reserved to the final stages of the speciation process …
