2. Occurring among populations having such a distribution: allopatric speciation.

They estimated the divergence time of the 2 lineages to be between 780,000 and 920,000 years ago, far preceding the Last Glacial Maximum (LGM) and, therefore, refuting Burford and Larsons's (2007) hypothesis that the LGM caused allopatric speciation within S.
Furthermore, there are instances of clear associations between the allopatric distribution of tree fern species and well-documented geological boundaries.
Temperature induced range expansion can cause novel range overlap between formerly allopatric species and can lead to extensive hybridisation in these new sympatric areas.

Anecdotal evidence suggests that El Nino Southern Oscillation (ENSO) plays significant roles in range expansions and contractions of both species (Kerstitch and Bertsch 2007), which otherwise have allopatric ranges, with the boundary at Punta Eugenia and Isla Cedros, Mexico (Angulo Campillo 2003, 2005).
