The BPP program for species tree estimation and species delimitation [PDF]

open access: yes, 2016
This paper provides an overview and a tutorial of the BPP program, which is a Bayesian MCMC program for analyzing multi-locus genomic sequence data under the multispecies coalescent model. An example dataset of five nuclear loci from the East Asian brown

Exploring the Leaf Beetle Fauna (Coleoptera: Chrysomelidae) of an Ecuadorian Mountain Forest Using DNA Barcoding.

open access: yesPLoS ONE, 2016
BackgroundTropical mountain forests are hotspots of biodiversity hosting a huge but little known diversity of insects that is endangered by habitat destruction and climate change.

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

open access: yesEcology 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

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

Unguided Species Delimitation Using DNA Sequence Data from Multiple Loci [PDF]

open access: yes, 2014
A method was developed for simultaneous Bayesian inference of species delimitation and species phylogeny using the multispecies coalescent model. The method eliminates the need for a user-specified guide tree in species delimitation and incorporates ...

Delimiting Species without Monophyletic Gene Trees [PDF]

open access: yesSystematic Biology, 2007
Genetic data are frequently used to delimit species, where species status is determined on the basis of an exclusivity criterium, such as reciprocal monophyly. Not only are there numerous empirical examples of incongruence between the boundaries inferred from such data compared to other sources like morphology -- especially with recently derived ...

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

open access: yesBMC 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.

Multispecies coalescent delimits structure, not species [PDF]

open access: yesProceedings 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 ...

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

open access: yesEcology 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.

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

open access: yesEcology 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 ...
