Delimiting Species-Poor Data Sets using Single Molecular Markers: A Study of Barcode Gaps, Haplowebs and GMYC [PDF]

open access: bronzeSystematic 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 GMYC model: insights from a butterfly survey [PDF]

open access: bronzeMethods 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. We here examine an array of factors affecting GMYC resolution (tree reconstruction method, taxon sampling ...

Two new species of the Drawida japonica species complex (Oligochaeta, Moniligastridae) from East Asia delimited by integrative taxonomic methods [PDF]

open access: yesZooKeys
The Drawida japonica (Michaelsen, 1892) species complex is a cosmopolitan earthworm group that is widely distributed throughout Asia, and has a high degree of diversity.

Species delimitation and DNA barcoding for Chinese Mantodea (Insecta, Dictyoptera) [PDF]

open access: yesZooKeys
DNA barcoding has been proposed as a rapid and reliable tool for animal identification and species delineation. The 5’ end of the mitochondrial cytochrome c oxidase I gene (COI-5P) was sequenced for 318 specimens of 55 mantis species.

Effects of phylogenetic reconstruction method on the robustness of species delimitation using single‐locus data [PDF]

open access: yesMethods in Ecology and Evolution, 2014
1. Coalescent-based species delimitation methods combine population genetic and phylogenetic theory to provide an objective means for delineating evolutionarily significant units of diversity.

Phylogenetic estimation error can decrease the accuracy of species delimitation: a Bayesian implementation of the general mixed Yule-coalescent model

open access: yesBMC Evolutionary Biology, 2012
Background Species are considered the fundamental unit in many ecological and evolutionary analyses, yet accurate, complete, accessible taxonomic frameworks with which to identify them are often unavailable to researchers.

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]

open access: yesMol Ecol Resour
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

Diversity of <i>Rhyacophila</i> (Trichoptera, Rhyacophilidae) in the Hengduan Mountains. [PDF]

open access: yesZookeys
Abstract Aquatic insects are particularly dependent on environmental conditions because their life cycles are directly linked to physico-chemical conditions in freshwater habitats.
