The BPP program for species tree estimation and species delimitation [PDF]
Environmental Epigenetics, 2015 This paper provides an overview and a tutorial of the BPP program, which is a Bayesian MCMC program for analyzing multi-locus genomic sequence data under the multispecies coalescent model. An example dataset of five nuclear loci from the East Asian brown

The art and science of species delimitation [PDF]
Environmental Epigenetics, 2015 Abstract DNA-based approaches to systematics have changed dramatically during the last two decades with the rise of DNA barcoding methods and newer multi-locus methods for species delimitation. During the last half-decade, partly driven by the new sequencing technologies, the focus has shifted to multi-locus sequence data and the ...

The hitchhiker's guide to single‐locus species delimitation
Molecular Ecology Resources, 2018 AbstractMolecular approaches to species delimitation are increasingly used to ascertain the number of species in a sample prior to taxonomic, ecological or physiological studies. Although multilocus approaches are gaining fast in popularity, single‐gene methods still predominate in the literature.

Species delimitation is the process of determining whether a group of sampled individuals belong to the same species or to different species. The criteria used to delimit species differ across taxonomic groups, and the methods for delimiting species have changed over time, with a dramatic rise in the popularity of genomic approaches recently.

Delimitating species in paleoanthropology
Evolutionary Anthropology: Issues, News, and Reviews, 2014Evolutionary biologists created a large twentieth‐century literature about delimiting biological species. Paleontologists contributed the unique complications of deep time. Toward century's end, one participant wrote: “In all probability more paper has been consumed on the questions of the nature and definition of the species than any other subject in ...

Species delimitations – not ‘only descriptive’
Organisms Diversity & Evolution, 2011Species descriptions as well as all other kinds of species delimitations within revisionary work are not ‘only descriptive’, as is often stated, but include several genuinely scientific, i.e. potentially falsifiable hypotheses: (1) The specimens under study represent a new or so far incorrectly defined species; (2) the phylogenetic position of the ...

Taxonomy and species delimitation in Cryptosporidium
Experimental Parasitology, 2010Amphibians, reptiles, birds and mammals serve as hosts for 19 species of Cryptosporidium. All 19 species have been confirmed by morphological, biological, and molecular data. Fish serve as hosts for three additional species, all of which lack supporting molecular data. In addition to the named species, gene sequence data from more than 40 isolates from

Species delimitation – a geneious plugin for the exploration of species boundaries
Molecular Ecology Resources, 2010AbstractSpecies Delimitation is a plugin to the Geneious software to support the exploration of species boundaries in a gene tree. The user assigns taxa to putative species and the plugin computes statistics relating to the probability of the observed monophyly or exclusivity having occurred by chance in a coalescent process.

Problems in species delimitation
2013The genera Staurastrum and Staurodesmus are notorious for their problematic species delimitation and, consequently, difficult identification of those species. One of the main causes for this is the infrequent occurrence of sexual reproduction, a process of gene exchange resulting in reduced morphological variation.

Operational Criteria for Delimiting Species
Annual Review of Ecology, Evolution, and Systematics, 2004▪ Abstract Species are routinely used as fundamental units of analysis in biogeography, ecology, macroevolution, and conservation biology. A large literature focuses on defining species conceptually, but until recently little attention has been given to the issue of empirically delimiting species.
