Definition of allopatric in English: allopatricadjective ˌaləˈpatrɪkˌaləˈpatrik Biology 1(of animals or plants, especially of related species or populations) occurring in separate non-overlapping geographical areas. Compare with sympatric Example sentencesExamples - For example, have allopatric populations of a parasitic species independently evolved egg or nestling mimicry of the same host species?
- Patterns of diversity of beech in Europe are not complicated by the existence of interfertile species, except for the presence of an allopatric related beech species in Asia minor.
- The two species have a largely allopatric altitudinal distribution on Hokkaido Island, Japan, proposed to be the result of temperature-mediated competition.
- Some zoogeographic species consist of two or more related populations that are allopatric in distribution (geographically separate) and are inferred to be reproductively isolated from each other.
- Biological species status is more complex, and application of the biological species concept to allopatric populations is problematic.
- 1.1 (of speciation) taking place as a result of allopatric separation.
Example sentencesExamples - Such barriers are some kind of geographic feature which isolates parts of populations, and leads to allopatric speciation.
- If most speciation is allopatric, what would we expect to see in terms of the fossil record?
- I have no competence to debate his scientific ideas - if speciation is mostly allopatric, or if it is sympatric, or something else, that is not a philosophical matter.
- Relatively large genetic distances between populations suggest long periods of isolation and allopatric speciation.
- In the classic case of allopatric speciation, gene flow is eliminated completely because of a geographic barrier.
Derivatives noun Biology Second, differentiation may have evolved in allopatry following long-distance dispersal of ‘founder’ individuals across pre-existing barriers. Example sentencesExamples - The predominant view is that new species arise most often in allopatry where geographically isolated populations of the same ancestral species diverge progressively.
- In general, sizes of island individuals are approximately intermediate in size between those in the region of origin (where they are sympatric and small) and those in the region of allopatry.
- For instance, positive correlations between size and dominance were evident among juvenile Atlantic salmon and brown trout when the two species were in allopatry but not when they were living sympatrically.
- The allopatry of Middle American subspecies, and their diversification, may be attributable to habitat preferences.
