Definition of vicariance in English:

vicariance

nounvɪˈkɛːrɪənsvʌɪˈkɛːrɪənsvīˈke(ə)rēəns

mass nounBiology

The geographical separation of a population, typically by a physical barrier such as a mountain range or river, resulting in a pair of closely related species.
〔生〕（因地理分隔形成的）分替，替代，离散
Example sentencesExamples
- And third, differentiation may have evolved in allopatry as a contiguous ancestral population became fragmented by vicariance.
- The biogeographic patterns of vicariance and range expansion may also provide insight to the mechanics of this extinction event.
- If allopatric taxa are older than the barrier that separates them, vicariance is the most parsimonious explanation for their divergence; if the barrier is older, dispersal is most parsimonious.
- Phylogenetic biogeography resolved patterns of both vicariance and geodispersal and revealed that range expansions were more abundant than range contractions in Devonian phyllocarids.
- It also can be used to identify both episodes of vicariance and congruent range expansion (geo-dispersal) that allow biogeographic patterns to be considered in the context of tectonic and climatic change.

Origin

1950s: from Latin vicarius 'substitute' + -ance.
