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 Phylogenetics Relationship of Pangasiid Catfishes in Peninsular Malaysia Revealed the Impacts of Aquaculture on the Native Species Conservation

open access: yesHydrobiology, 2023
Pangasiids are an economically significant group of catfish, and many pangasiids are threatened in the wild from anthropogenic pressures, including increases in fishing pressure, habitat degradation, and improperly managed aquaculture practices.

To be or not to be… Integrative taxonomy and species delimitation in the daddy long-legs spiders of the genus Physocyclus (Araneae, Pholcidae) using DNA barcoding and morphology [PDF]

open access: yesZooKeys, 2022
Integrative taxonomy is crucial for discovery, recognition, and species delimitation, especially in underestimated species complex or cryptic species, by incorporating different sources of evidence to construct rigorous species hypotheses.

Interrogation of earthworm (Clitellata: Haplotaxida) taxonomy and the DNA sequence database

open access: yesJournal of Asia-Pacific Biodiversity, 2021
The DNA sequence database assists us with great potential in species identification because it is practical and affordable to perform. More often, the identification using molecular data helps to identify morphologically variable individuals of same ...

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

open access: yesDiversity, 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.

Evolution of microgastropods (Ellobioidea, Carychiidae): integrating taxonomic, phylogenetic and evolutionary hypotheses [PDF]

open access: yes, 2013
BACKGROUND: Current biodiversity patterns are considered largely the result of past climatic and tectonic changes. In an integrative approach, we combine taxonomic and phylogenetic hypotheses to analyze temporal and geographic diversification of epigean (

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.
