Factors affecting the efficiency of molecular species delimitation in a species‐rich insect family

Molecular Ecology Resources, 2021
In the context of global biodiversity loss, molecular species delimitation approaches can be very useful for accelerating species discovery through DNA taxonomy and inventory through DNA metabarcoding.

Molecular species delimitation of shrub frogs of the genus Pseudophilautus (Anura, Rhacophoridae).

PLoS ONE, 2021
Sri Lanka is an amphibian hotspot of global significance. Its anuran fauna is dominated by the shrub frogs of the genus Pseudophilautus. Except for one small clade of four species in Peninsular India, these cool-wet adapted frogs, numbering some 59 ...

Deciphering the Taxonomic Delimitation of Ottelia acuminata (Hydrocharitaceae) Using Complete Plastomes as Super-Barcodes

Frontiers in Plant Science, 2021
Accurate species delimitation and identification, which is a challenging task in traditional morphology-based taxonomy, is crucial to species conservation.

Delimitation despite discordance: Evaluating the species limits of a confounding species complex in the face of mitonuclear discordance

Ecology and Evolution, 2021
The delimitation of species is an essential pursuit of biology, and proper taxonomies are crucial for the assessment and conservation management of organismal diversity.

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

, 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 (

Contemporary Methods and Evidence for Species Delimitation

Ichthyology & Herpetology, 2021
Over the last two decades, mitochondrial DNA (mtDNA) sequence data, as well as analyses of nuclear DNA based on the multispecies coalescent model, have increasingly been used to delimit species, sometimes based on limited sampling and without other ...

Increasing the digital repository of DNA barcoding sequences of sand flies (Psychodidae: Phlebotominae) [PDF]

, 2019
Sand f ly identification is complex because it depends on the expertise of the taxonomist. The females show subtle morphological differences and the occurrence of the species complexes are usual in this taxon.

Integrative taxonomy by molecular species delimitation: multi-locus data corroborate a new species of Balkan Drusinae micro-endemics

BMC Evolutionary Biology, 2017
Background Taxonomy offers precise species identification and delimitation and thus provides basic information for biological research, e.g. through assessment of species richness.

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

Diversity, 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.
