Scaling Up Species Delimitation From DNA Barcodes to Whole Organelle Genomes: Strong Evidence for Discordance Among Genes and Methods for the Red Alga Dasyclonium. [PDF]

Mol Ecol Resour
ABSTRACT Molecular sequence data have become a ubiquitous tool for delimiting species and are particularly important in organisms where morphological traits are not informative about species boundaries. A range of statistical methods have been developed to derive species limits from molecular data, for example, by quantifying changes in branching ...

Enhancing species discovery and description in algal turfs: A case study in the green alga Pseudoderbesia (Bryopsidales). [PDF]

J Phycol
Abstract Algal turfs are assemblages consisting of small marine green, brown, and red algae on the scale of millimeters to a few centimeters. Due to their small size, they have been less intensively studied by macroalgal taxonomists, and they also fall outside the scope of microalgal taxonomists, who tend to focus on smaller, often unicellular, taxa ...

Integrative taxonomy suggests hidden diversity within the fish genus Cyttopsis (Zeiformes, Parazenidae). [PDF]

J Fish Biol
Abstract Nine specimens of Cyttopsis rosea (Zeiformes: Parazenidae) were collected during scientific surveys at three different locations in the northeast Atlantic. All nine specimens were included in the molecular analysis, adding new cytochrome c oxidase subunit I sequences to public databases.

Assessing Current Fish Diversity in the Yellow River Basin by Integrating Large-Scale Barcoding and Morphological Data. [PDF]

Ecol Evol
In this study, 127 sampling points were sampled in the Yellow River Basin, and a DNA barcode database of 3011 sequences and 110 species was constructed. We found that diversity of fish species in the Yellow River Basin has been seriously underestimated.

Eight new species of the genus Anaplecta Burmeister, 1838 (Blattodea: Blattoidea: Anaplectidae) from China based on molecular and morphological data

European Journal of Taxonomy, 2020
In this study, we examine 500 specimens of Anaplecta collected from China, of which 26 samples were used for COI sequencing. We confirm eight new species, i.e., Anaplecta corneola Deng & Che sp. nov., Anaplecta staminiformis Deng & Che sp.

Combining and Comparing Coalescent, Distance and Character-Based Approaches for Barcoding Microalgaes: A Test with Chlorella-Like Species (Chlorophyta). [PDF]

PLoS ONE, 2016
Several different barcoding methods of distinguishing species have been advanced, but which method is the best is still controversial. Chlorella is becoming particularly promising in the development of second-generation biofuels. However, the taxonomy of

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]

ZooKeys, 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.

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

PLoS 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 Species Delimitation Using COI Barcodes of Mealybugs (Hemiptera: Pseudococcidae) from Coffee Plants in Espírito Santo, Brazil

Diversity, 2023
Mealybugs are insects belonging to the family Pseudococcidae. This family includes many plant-pest species with similar morphologies, which may lead to errors in mealybug identification and delimitation.
