DNA barcoding: species delimitation in tree peonies

Science in China Series C: Life Sciences, 2009
Delimitations of species are crucial for correct and precise identification of taxa. Unfortunately "species" is more a subjective than an objective concept in taxonomic practice due to difficulties in revealing patterns of infra- or inter-specific variations.

SpedeSTEM: a rapid and accurate method for species delimitation

Molecular Ecology Resources, 2010
AbstractWe describe a software package (SpedeSTEM) that allows researchers to conduct a species delimitation analysis using intraspecific genetic data. Our method operates under the assumption that a priori information regarding group membership is available, for example that samples are drawn from some number of described subspecies, races or distinct

Species delimitation in the genus Lemna

Aquatic Botany, 1975
Abstract Species delimination in the genus Lemna is rendered more difficult by a pronounced lack of taxonomically useful characters (owing to simplified organization) and by the occurrence of true intermediate forms (owing to vegetative multiplication of mutants and hybrids).

Species Delimitation and Exploration of Species Partitions with ASAP and LIMES

DNA barcoding plays an important role in exploring undescribed biodiversity and is increasingly used to delimit lineages at the species level (see Chap. 4 by Miralles et al.). Although several approaches and programs have been developed to perform species delimitation from datasets of single-locus DNA sequences, such as DNA barcodes, most of these were

Molecular Variation and the Delimitation of Species

1996
Species are widely regarded as fundamental elements of modern biology, but practitioners of species biology—those who delimit and study the attributes of species, and seek to understand the manner in which species originate—have yet to agree on what a species is.
