A fundamental issue in speciation research is to evaluate phenotypic variation and the
genomics driving the evolution of reproductive isolation between sister taxa. Above all …

Chromosomal inversions have been shown to play a major role in a local adaptation by
suppressing recombination between alternative arrangements and maintaining beneficial …

Hybrid zones of ecologically divergent populations are ideal systems to study the interaction
between natural selection and gene flow during the initial stages of speciation. Here, we …

Low dispersal marine intertidal species facing strong divergent selective pressures
associated with steep environmental gradients have a great potential to inform us about …

Speciation requires the acquisition of reproductive isolation, and the circumstances under
which this could evolve are of great interest. Are new species formed after the acquisition of …

Chromosomal inversions have long been recognized for their role in local adaptation. By
suppressing recombination in heterozygous individuals, they can maintain coadapted gene …

Parallel evolution of similar phenotypes provides strong evidence for the operation of natural
selection. Where these phenotypes contribute to reproductive isolation, they further support …

Chromosomal rearrangements can lead to the coupling of reproductive barriers, but whether
and how they contribute to the completion of speciation remains unclear. Marine snails of …

Characterizing the patterns of hybridization between closely related species is crucial to
understand the role of gene flow in speciation. In particular, systems comprising multiple …

When divergent populations are connected by gene flow, the establishment of complete
reproductive isolation usually requires the joint action of multiple barrier effects. One …
