Delimitation despite discordance: Evaluating the species limits of a confounding species complex in the face of mitonuclear discordance

Ecology and Evolution, 2021
The delimitation of species is an essential pursuit of biology, and proper taxonomies are crucial for the assessment and conservation management of organismal diversity.

Deciphering the Taxonomic Delimitation of Ottelia acuminata (Hydrocharitaceae) Using Complete Plastomes as Super-Barcodes

Frontiers in Plant Science, 2021
Accurate species delimitation and identification, which is a challenging task in traditional morphology-based taxonomy, is crucial to species conservation.

Integrative taxonomy by molecular species delimitation: multi-locus data corroborate a new species of Balkan Drusinae micro-endemics

BMC Evolutionary Biology, 2017
Background Taxonomy offers precise species identification and delimitation and thus provides basic information for biological research, e.g. through assessment of species richness.

Ecological niche modelling and nDNA sequencing support a new, morphologically cryptic beetle species unveiled by DNA barcoding. [PDF]

, 2011
DNA sequencing techniques used to estimate biodiversity, such as DNA barcoding, may reveal cryptic species. However, disagreements between barcoding and morphological data have already led to controversy.

Is population subdivision different from speciation? From phylogeography to species delimitation

Ecology and Evolution, 2020
Species‐level diversity and the underlying mechanisms that lead to the formation of new species, that is, speciation, have often been confounded with intraspecific diversity and population subdivision.

Cox1 barcoding versus multilocus species delimitation: validation of two mite species with contrasting effective population sizes

Parasites & Vectors, 2019
Background The cox1-barcoding approach is currently extensively used for high-throughput species delimitation and discovery. However, this method has several limitations, particularly when organisms have large effective population sizes.

Multiple species delimitation approaches with COI barcodes poorly fit each other and morphospecies – An integrative taxonomy case of Sri Lankan Sericini chafers (Coleoptera: Scarabaeidae)

Ecology and Evolution, 2022
DNA taxonomy including barcoding and metabarcoding is widely used to explore the diversity in biodiversity hotspots. In most of these hotspot areas, chafers are represented by a multitude of species, which are well defined by the complex shape of male ...

COI-Barcoding and Species Delimitation Assessment of Toad-Headed Agamas of the Genus Phrynocephalus (Agamidae, Squamata) Reveal Unrecognized Diversity in Central Eurasia

Diversity, 2023
We provide a diversity assessment of the agamid genus Phrynocephalus Kaup, 1825. We analyze COI mtDNA barcodes from 385 individuals sampled all over Phrynocephalus range.

Multispecies coalescent delimits structure, not species [PDF]

Proceedings of the National Academy of Sciences, 2017
Significance Despite its widespread application to the species delimitation problem, our study demonstrates that what the multispecies coalescent actually delimits is structure. The current implementations of species delimitation under the multispecies coalescent do not provide any way for distinguishing between structure due to population ...

Species delimitation and hybridization history of a hazel species complex

Annals of Botany, 2021
AbstractBackground and AimsHybridization increases species adaptation and biodiversity but also obscures species boundaries. In this study, species delimitation and hybridization history were examined within one Chinese hazel species complex (Corylus chinensis–Corylus fargesii).
