Delimiting Species-Poor Data Sets Using Single Molecular Markers: A Study of Barcode Gaps, Haplowebs and GMYC. [PDF]
Systematic Biology, 2015 Most single-locus molecular approaches to species delimitation available to date have been designed and tested on data sets comprising at least tens of species, whereas the opposite case (species-poor data sets for which the hypothesis that all individuals are conspecific cannot by rejected beforehand) has rarely been the focus of such attempts.

Factors affecting species delimitations with the
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.

COI Barcoding Unveils Hidden Fish Diversity and Potential Cryptic Lineages in Inner Mongolia, China [PDF]
Ecology and Evolution, Volume 16, Issue 10, October 2026.Using 1080 COI barcode sequences from 99 sites across Inner Mongolia, we uncovered 70 molecular OTUs (62 morphospecies), three cryptic lineages, and deep genetic splits within widespread species. Our results provide the first regional barcode reference while revealing both the power and the limitations of single‐locus barcoding for rapid diversity ...

Unveiling the Ongoing Expansion of Bullheads of the Genus Ameiurus (Actinopteri: Siluriformes) in the Dnipro River Basin, Ukraine: New Distributional Records and Genetic Diversity [PDF]
Ecology and Evolution, Volume 16, Issue 11, November 2026.This study investigates the rapid expansion, genetic structure, and phenotypic traits of two non‐native ictalurids, Ameiurus nebulosus and Ameiurus melas, within the under‐researched Dnipro River basin, Ukraine. Integrating mtDNA COI barcoding with morphological DAPC analysis, we provide the first molecularly verified record of A.

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 ...

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.

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 ...

Phylogeography and Population Genetics of the Kentucky Endemic Cave Beetle Genus Neaphaenops Jeannel (1920) (Coleoptera: Carabidae: Trechini) [PDF]
Ecology and Evolution, Volume 16, Issue 10, October 2026.This study investigated the evolutionary history and population structure of the genus Neaphaenops, using CO1 gene sequencing from 62 cave populations. The phylogenetic analysis revealed two distinct mega‐populations—northern and southern—separated by the Barren River, leading to the conclusion that the four proposed subspecies are invalid. The results

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.
