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.

Cox1 barcoding versus multilocus species delimitation: validation of two mite species with contrasting effective population sizes

open access: yesParasites & Vectors, 2019
Background The cox1-barcoding approach is currently extensively used for high-throughput species delimitation and discovery. However, this method has several limitations, particularly when organisms have large effective population sizes.

Coalescent-based species delimitation in the sand lizards of the Liolaemus wiegmannii complex (Squamata: Liolaemidae) [PDF]

open access: yes, 2019
Coalescent-based algorithms coupled with the access to genome-wide data have become powerful tools forassessing questions on recent or rapid diversification, as well as delineating species boundaries in the absence of reciprocal monophyly.

A rapid and scalable method for multilocus species delimitation using Bayesian model comparison and rooted triplets [PDF]

open access: yes, 2016
Multilocus sequence data provide far greater power to resolve species limits than the single locus data typically used for broad surveys of clades. However, current statistical methods based on a multispecies coalescent framework are computationally ...

The role of integrative taxonomy in the conservation management of cryptic species: the taxonomic status of endangered earless dragons (Agamidae: Tympanocryptis) in the grasslands of Queensland, Australia. [PDF]

open access: yesPLoS ONE, 2014
Molecular phylogenetics is increasingly highlighting the prevalence of cryptic species, where morphologically similar organisms have long independent evolutionary histories.

Values, regulation, and species delimitation [PDF]

open access: yesZootaxa, 2018
Garnett and Christidis (2017) [hereafter GC] recently proposed that the International Union of the Biological Sciences should centrally regulate the taxonomy of complex organisms. Their proposal was met with much criticism (e.g. Hołyński 2017; Thomson et al., 2018), and perhaps most extensively from Raposo et al. (2017) in this journal. The main target

Model-based species delimitation: are coalescent species reproductively isolated? [PDF]

open access: yesSystematic Biology, 2019
ABSTRACTA large and growing fraction of systematists define species as independently evolving lineages that may be recognized by analyzing the population genetic history of alleles sampled from individuals belonging to those species. This has motivated the development of increasingly sophisticated statistical models rooted in the multispecies ...

Rare coral under the genomic microscope: timing and relationships among Hawaiian Montipora [PDF]

open access: yes, 2019
Background Evolutionary patterns of scleractinian (stony) corals are difficult to infer given the existence of few diagnostic characters and pervasive phenotypic plasticity.

Timeless standards for species delimitation

open access: yesZootaxa, 2016
Recently a new species of bombyliid fly, Marleyimyia xylocopae, was described by Marshall & Evenhuis (2015) based on two photographs taken during fieldwork in the Republic of South Africa. This species has no preserved holotype. The paper generated some buzz, especially among dipterists, because in most cases photographs taken in the field provide ...
