Ecological speciation in sympatric palms: 3. Genetic map reveals genomic islands underlying species divergence in Howea
Although it is now widely accepted that speciation can occur in the face of continuous gene flow, with little or no spatial separation, the mechanisms and genomic architectures that permit such divergence are still debated. Here, we examined speciation in the face of gene flow in the Howea palms of...Papadopulos, Alexander ; Igea, Javier ; Dunning, Luke ; Osborne, Owen ; Quan, Xueping …

Ecological speciation in sympatric palms: 4. Demographic analyses support speciation of Howea in the face of high gene flow
The idea that populations must be geographically isolated (allopatric) to evolve into separate species has persisted for a long time. It is now clear that new species can also diverge despite ongoing genetic exchange, but few accepted cases of speciation in sympatry have held up when scrutinized using modern approaches....Papadopulos, Alexander ; Igea, Javier ; Smith, Thomas ; Hutton, Ian ; Baker, William …

Speciation in Howea palms occurred in sympatry, was preceded by ancestral admixture, and was associated with edaphic and phenological adaptation
Howea palms are viewed as one of the most clear-cut cases of speciation in sympatry. The sister species H. belmoreana and H. forsteriana are endemic to the oceanic Lord Howe Island, Australia, where they have overlapping distributions and are reproductively isolated mainly by flowering time differences. However, the potential role...Osborne, Owen ; Ciezarek, Adam ; Wilson, Trevor ; Crayn, Darren ; Hutton, Ian …
