Methods integrating morphology, genetics and ecology to decide where species boundaries lie.
Integrative taxonomy combines multiple lines of evidence: morphology, DNA, behaviour, ecology and geography. Coalescent-based methods test species hypotheses.
Integrative taxonomy reduces errors from relying on a single data type. Machine learning aids analysis.
Example: acoustic differences separate cryptic bat species.

Species Delimitation is one of the 52 topics in Taxonomy & Biodiversity. It is rated Advanced, so it suits learners who want specialist depth. Related topics in this area include Cryptic Species, Conservation Biology, Hybridisation and Species Boundaries.
African elephants were split into savanna and forest species based on genetics.
Work through the Beginner topics in Taxonomy & Biodiversity first, such as Taxonomy, Binomial Nomenclature, Taxonomic Hierarchy, then return to Species Delimitation. Advanced topics assume the Intermediate vocabulary.
The closest topics to Species Delimitation are Cryptic Species, Conservation Biology, Hybridisation and Species Boundaries, IUCN Red List Criteria. Comparing them side by side is a good way to see how the ideas connect.
Read the summary and the in-depth section, then use the quick check on the interactive lesson for Species Delimitation. To practise the whole of Taxonomy & Biodiversity, use the Taxonomy & Biodiversity quiz.
Species Delimitation: Methods integrating morphology, genetics and ecology to decide where species boundaries lie. Cryptic Species: Distinct species that look nearly identical and are separated only by molecular or behavioural evidence. Read both side by side and note what each one explains.
First, read the summary and write the definition in your own words. Second, read the in-depth section and note any example. Third, compare it with Cryptic Species and explain the difference aloud. Finally, take the Taxonomy & Biodiversity quiz and come back to this page for any question you miss.
