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 …

Abstract Here, we describe Assemble Species by Automatic Partitioning (ASAP), a new
method to build species partitions from single locus sequence alignments (ie, barcode data …

True fungi (Fungi) and fungus-like organisms (eg Mycetozoa, Oomycota) constitute the
second largest group of organisms based on global richness estimates, with around 3 …

Interpretations and analytical practices surrounding DNA barcoding are examined using a
compilation of 3,756 papers (as of December 31, 2018) with “DNA Barcode” in the abstract …

Biodiversity loss from disturbances caused by human activities means that species are
disappearing at an ever increasing rate. The high number of species that have yet to be …

Motivation In recent years, molecular species delimitation has become a routine approach
for quantifying and classifying biodiversity. Barcoding methods are of particular importance …

The continuous decline in Earth's biodiversity represents a major crisis and challenge for the
21st century, and there is international political agreement to slow down or halt this decline …

Most of arthropod biodiversity is unknown to science. Consequently, it has been unclear
whether insect communities around the world are dominated by the same or different taxa …

Species are fundamental units in biological research and can be defined on the basis of
various operational criteria. There has been growing use of molecular approaches for …
