- Specialized
- The evidence of secondary contact of formerly allopatric populations in both the haplotype network and mismatch analyses strongly suggests fragmentation of the populations of studied fishes, most likely by reduction in flow during dry periods.
- allopatric speciation
Examples
-
Evolution can be studied directly; change by the ordinary route of allopatric speciation is palpable in geological evidence.
Academic text (1992) -
Most of our paleontological colleagues missed this insight because they had not studied evolutionary theory and either did not know about allopatric speciation or had not considered its translation to geological time.
Academic text (1992) -
And from that he gets a measurement when allopatric and a measurement when sympatric.
-
Most cases are allopatric, but an increasing number of examples have been found of multiple pollinator species living in sympatry.
Academic text (2005) -
Punctuated equilibrium coupled with allopatric speciation strikes me as having greater explanatory power.
Blog text (29) -
That would have been sympatric speciation, which was less likely to occur because of gene flow with the forest stock than allopatric speciation, the evolution of a new species in a geographically separated area.
Academic text (1995) -
Punctuated equilibrium gains its rationale from the idea, also a standard component of the allopatric speciation theory, that most peripherally isolated populations are relatively small and undergo their characteristic changes at a rate that translates into geological time as an instant.
Academic text (1992) -
In allopatric speciation, different populations evolve separately due to geographic isolation.
-
Many species of birds exhibit allopatric patterns, thriving in isolated areas without contact.
-
Allopatric populations of the same species can develop distinct characteristics over time.

Morphology
allopatric = allopatry (opaque) = allo + patry + ic
The adjective is a learned scientific formation from Greek combining forms ('allo-' meaning 'other' and a patr-/patry element relating to homeland/area'), so its meaning is unlikely to be deduced by an average B1 learner.
Etymology
Allopatric comes from Greek parts allo- meaning 'other' and patria meaning 'homeland' or 'country', the same root you see in patriotic. So, allopatric describes groups or species that live in 'other homelands', in different places so they do not meet.
