Delimiting Species in Recent Radiations [PDF]
Despite considerable effort from the systematics community, delimiting species boundaries in recent radiations remains a daunting challenge. We argue that genealogical approaches, although sometimes useful, may not solve this important problem, because recently derived species often have not had sufficient time to achieve monophyly. Instead, we suggest

DNA barcoding and DNA‐based species delimitation are major tools in DNA taxonomy. Sampling has been a central debate in this context, because the geographical composition of samples affects the accuracy and performance of DNA barcoding.

Integrative species delimitation helps to find the hidden diversity of the leaf-litter frog Ischnocnema manezinho (Garcia, 1996) (Anura, Brachycephalidae), endemic to the southern Atlantic Forest [PDF]
Background The delimitation of cryptic species is a challenge for biodiversity conservation. Anurans show high cryptic diversity levels, and molecular species delimitation methods could help identify putative new species.

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,

Fast genome-based delimitation of Enterobacterales species.
Average Nucleotide Identity (ANI) is becoming a standard measure for bacterial species delimitation. However, its calculation can take orders of magnitude longer than similarity estimates based on sampling of short nucleotides, compiled into so-called ...

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 with Gene Flow [PDF]
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]
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.

A species delimitation approach in the Trochulus sericeus/hispidus complex reveals two cryptic species with a sharp contact zone [PDF]
Background: Mitochondrial DNA sequencing increasingly results in the recognition of genetically divergent, but morphologically cryptic lineages. Species delimitation approaches that rely on multiple lines of evidence in areas of co-occurrence are ...
