- Agamospecies
- A species that does not reproduce sexually but instead by cloning.[1] Agamospecies are sometimes represented by species complexes that contain some diploid individuals and other apomitic forms—in particular, plant species that can reproduce via agamospermy.[2]
- Allochronic isolation
- Isolation of two populations of a species due to a change in breeding periods. This isolation acts as a precursor to allochronic speciation, speciation resulting from two populations of a species that have become isolated due to differences in breeding periods. An example is the periodical 13- and 17-year Magicicada species.[2]
- Allo-parapatric speciation
- A mode of speciation where divergence occurs in allopatry and is completed upon secondary contact of the populations--effectively a form of reinforcement.[3][2]
- Allopatric speciation
- A mode of speciation where the evolution of reproductive isolation is caused by geographic separation of a species population.[4] Also called geographic speciation, vicariance, vicariant speciation, or dichopatric speciation.
- Allopatric taxa
- Specific species that are allopatrically distributed.
- Allopatry
- Species populations that exist geographically separated from one another.

- A model of peripatric speciation developed by Kenneth Y. Kanneshiro where a sexual species experiences a population bottleneck—that is, when the genetic variation is reduced due to small population size—mating discrimination among females may be altered by the decrease in courtship behaviors or displays of males. This allows sexual selection to give rise to novel sexual traits in the new population.[13]
