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 ...

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.

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

DNA barcoding: species delimitation in tree peonies
Science in China Series C: Life Sciences, 2009Delimitations of species are crucial for correct and precise identification of taxa. Unfortunately "species" is more a subjective than an objective concept in taxonomic practice due to difficulties in revealing patterns of infra- or inter-specific variations.

Delimitation of cryptic species inside Claviceps purpurea
Fungal Biology, 2015Claviceps purpurea is an ovarian parasite infecting grasses (Poaceae) including cereals and forage plants. This fungus produces toxic alkaloids and consumption of contaminated grains can cause ergotism in humans and other mammals. Recent molecular genetics studies have indicated that it included three cryptic species (G1, G2, G3).

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 ...
