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.

Delimitating species in paleoanthropology

Evolutionary Anthropology: Issues, News, and Reviews, 2014
Evolutionary 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 ...

Taxonomy and species delimitation in Cryptosporidium

Experimental Parasitology, 2010
Amphibians, 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 delimitations – not ‘only descriptive’

Organisms Diversity & Evolution, 2011
Species 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 ...

Problems in species delimitation

2013
The 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.

Species delimitation – a geneious plugin for the exploration of species boundaries

Molecular Ecology Resources, 2010
AbstractSpecies 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.

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.

SpedeSTEM: a rapid and accurate method for species delimitation

Molecular Ecology Resources, 2010
AbstractWe describe a software package (SpedeSTEM) that allows researchers to conduct a species delimitation analysis using intraspecific genetic data. Our method operates under the assumption that a priori information regarding group membership is available, for example that samples are drawn from some number of described subspecies, races or distinct
