This is the opening paper in the special issue of Fungal Diversity, which collates the data on
defining species. Defining and recognizing species has long been a controversial issue …

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 …

DNA barcoding-type studies assemble single-locus data from large samples of individuals
and species, and have provided new kinds of data for evolutionary surveys of diversity. An …

Species delimitation is the act of identifying species‐level biological diversity. In recent
years, the field has witnessed a dramatic increase in the number of methods available for …

Within uncharacterized groups, DNA barcodes, short DNA sequences that are present in a
wide range of species, can be used to assign organisms into species. We propose an …

A method was developed for simultaneous Bayesian inference of species delimitation and
species phylogeny using the multispecies coalescent model. The method eliminates the …

The statistical rigor of species delimitation has increased dramatically over the past decade.
Coalescent theory provides powerful models for population genetic inference, and is now …

In the absence of recent admixture between species, bipartitions of individuals in gene trees
that are shared across loci can potentially be used to infer the presence of two or more …

Phylogenetic relationships among recently diverged species are often difficult to resolve due
to insufficient phylogenetic signal in available markers and/or conflict among gene trees …

The multispecies coalescent has provided important progress for evolutionary inferences,
including increasing the statistical rigor and objectivity of comparisons among competing …
