Recent advances in population genomics have triggered great interest in the genomic landscape of divergence in taxa with ‘porous’ species boundaries. One important obstable of previous studies of this topic was the low genomic coverage achieved. This issue can now be overcome by the use of ‘next generation’ or short-read DNA-sequencing approaches capable of assaying many thousands of...

Sympatric bromeliad species (Pitcairnia spp.) facilitate tests of mechanisms involved in species cohesion and reproductive isolation in Neotropical inselbergs

The roles of intra- and interspecific gene flow in speciation and species evolution are topics of great current interest in molecular ecology and evolutionary biology. Recent modelling studies call for new empirical data to test hypotheses arising from the recent shift from a ‘whole-genome reproductive isolation’ view to a ‘genic’ view of species and speciation. Particularly scarce (and...
