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

PLoS 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 ...

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

Anais 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

Methods 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 ...

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

Mitochondrial 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 ...

Species Delimitation, Phylogenetic Relationships, and Temporal Divergence Model in the Genus Aeromonas

Frontiers in Microbiology, 2018
The definition of species boundaries constitutes an important challenge in biodiversity studies. In this work we applied the Generalized Mixed Yule Coalescent (GMYC) method, which determines a divergence threshold to delimit species in a phylogenetic ...

Genetic and Morphological Analyses Demonstrate That Schizolecis guntheri (Siluriformes: Loricariidae) Is Likely to Be a Species Complex

Frontiers in Genetics, 2018
Schizolecis is a monotypic genus of Siluriformes widely distributed throughout isolated coastal drainages of southeastern Brazil. Previous studies have shown that fish groups found in isolated river basins tend to differentiate over time in the absence ...

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

Diversity, 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

Journal 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.

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

Ecology 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.

OTU Delimitation with Earthworm DNA Barcodes: A Comparison of Methods

Diversity, 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.
