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 …

Species‐level taxonomy derives from empirical sources (data and techniques) that assess
the existence of spatiotemporal evolutionary lineages via various species “concepts.” These …

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 …

The species problem has triggered the publication of an almost infinite number of theoretical
and practical studies, including quite a number of books. I should, therefore, perhaps briefly …

The issue of species delimitation has long been confused with that of species
conceptualization, leading to a half century of controversy concerning both the definition of …

Delineating species boundaries correctly is crucial to the discovery of life's diversity because
it determines whether or not different individual organisms are members of the same entity …

Ernst Mayr played a central role in the establishment of the general concept of species as
metapopulation lineages, and he is the author of one of the most popular of the numerous …

The Mexican transition zone (MTZ) is the complex area where the Neotropical and Nearctic
biotas overlap, including south-western United States, Mexico and a large part of Central …

the inferred species (a major focus of their paper was delimiting species in the presence of
gene flow). Both pairs of lineages were identified as separate populations (clusters) by …

The nature and definition of species continue to be matters of debate. Current views of
species often focus on their nature as lineages—maximal reproductive communities through …
