A good compromise: rapid and robust species proxies for inventorying biodiversity hotspots using the Terebridae (Gastropoda: Conoidea). [PDF]

open access: yesPLoS ONE, 2014
Devising a reproducible approach for species delimitation of hyperdiverse groups is an ongoing challenge in evolutionary biology. Speciation processes combine modes of passive and adaptive trait divergence requiring an integrative taxonomy approach to ...

Molecular delimitation methods validate morphologically similar species of red snappers (Perciformes: Lutjanidae)

open access: yesAnais da Academia Brasileira de Ciências, 2023
In this study, we tested the taxonomic validation of red snappers species (Southern red snapper Lutjanus purpureus; Silk snapper L. vivanus; Blackfin snapper L. buccanella; and Pacific red snapper L.

Factors affecting species delimitations with the GMYC model: insights from a butterfly survey

open access: yesMethods in Ecology and Evolution, 2013
Summary The generalized mixed Yule‐coalescent (GMYC) model has become one of the most popular approaches for species delimitation based on single‐locus data, and it is widely used in biodiversity assessments and phylogenetic community ecology. We here examine an array of factors affecting GMYC resolution (tree reconstruction method, taxon sampling ...

Species Delimitation and Phylogenetic Relationships in Ectobiid Cockroaches (Dictyoptera, Blattodea) from China.

open access: yesPLoS ONE, 2017
We collected Ectobiidae cockroach specimens from 44 locations in the south of the Yangtze valley. We obtained 297 COI sequences specimens and carried out phylogenetic and divergence dating analyses, as well as species delimitation analysis using a ...

DNA barcoding elucidates the population genetic diversity of venomous cobra species (Reptilia: Elapidae) in Indo-Bangladesh region

open access: yesMitochondrial DNA. Part B. Resources, 2020
The DNA barcode data of venomous cobra species (Naja naja and Naja kaouthia) are limited in the global database, especially from India and Bangladesh. Owing to the rapid success of DNA barcoding for discriminating a variety of species around the world ...

DNA Barcoding and geographical scale effect: The problems of undersampling genetic diversity hotspots

open access: yesEcology and Evolution, 2020
DNA barcoding identification needs a good characterization of intraspecific genetic divergence to establish the limits between species. Yet, the number of barcodes per species is many times low and geographically restricted.

DNA Barcoding and Species Delimitation for Dogfish Sharks Belonging to the Squalus Genus (Squaliformes: Squalidae)

open access: yesDiversity, 2022
The Squalus genus comprises a group of small demersal sharks occurring circumglobally, popularly known as dogfish sharks. This genus exhibits a conserved morphology, thus making correct morphological identification difficult.

A COI DNA barcoding survey of Pratylenchus species in the Great Plains Region of North America

open access: yesJournal of Nematology, 2019
Pratylenchus species are among the most common plant parasitic nematodes in the Great Plains Region of North America. Our goal was to survey Pratylenchus species diversity across the Great Plains region using a mitochondrial COI DNA barcode.

OTU Delimitation with Earthworm DNA Barcodes: A Comparison of Methods

open access: yesDiversity, 2022
Although DNA barcodes-based operational taxonomic units (OTUs) are increasingly used in earthworm research, the relative efficiency of the different methods available to delimit them has not yet been tested on a comprehensive dataset.

DNA Barcoding of Penaeidae (Decapoda; Crustacea): Non-Distance-Based Species Delimitation of the Most Economically Important Shrimp Family

open access: yesDiversity, 2021
The Penaeidae family includes some of the most economic and ecological important marine shrimp, comprising hundreds of species. Despite this importance and diversity, the taxonomic classification for penaeid shrimp has constantly been revised, and issues
