Genome-wide species delimitation analyses of a silverside fish species complex in central Mexico indicate taxonomic over-splitting

BMC Ecology and Evolution, 2022
Background Delimiting species across a speciation continuum is a complex task, as the process of species origin is not generally instantaneous. The use of genome-wide data provides unprecedented resolution to address convoluted species delimitation cases,

Disentangling the identity of Lebertia porosa Thor, 1900 using integrative taxonomy (Acari: Hydrachnidia)

European Journal of Taxonomy, 2022
Initial analyses of DNA barcode data from Norwegian populations attributed to the water mite Lebertia porosa Thor, 1900 revealed large genetic divergence and potentially cryptic species-level diversity.

Species Delimitation and Global Biosecurity [PDF]

Evolutionary Bioinformatics, 2011
Species delimitation directly impacts on global biosecurity. It is a critical element in the decisions made by national governments in regard to the flow of trade and to the biosecurity measures imposed to protect countries from the threat of invasive species. Here we outline a novel approach to species delimitation, “tip to root”,

Species Delimitation with Gene Flow [PDF]

Systematic Biology, 2016
Species are commonly thought to be evolutionarily independent in a way that populations within a species are not. In recent years, studies that seek to identify evolutionarily independent lineages (i.e., to delimit species) using genetic data have typically adopted multispecies coalescent approaches that assume that evolutionary independence is formed ...

Using phylogenetic and coalescent methods to understand the species diversity in the Cladia aggregata complex (Ascomycota, Lecanorales). [PDF]

PLoS ONE, 2012
The Cladia aggregata complex is one of the phenotypically most variable groups in lichenized fungi, making species determination difficult and resulting in different classifications accepting between one to eight species.

Exploring the Leaf Beetle Fauna (Coleoptera: Chrysomelidae) of an Ecuadorian Mountain Forest Using DNA Barcoding.

PLoS ONE, 2016
BackgroundTropical mountain forests are hotspots of biodiversity hosting a huge but little known diversity of insects that is endangered by habitat destruction and climate change.

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 ...

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.

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.

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.
