<i>Wolbachia</i> Host Shifts and Widespread Occurrence of Reproductive Manipulation Loci in European Butterflies Open
Wolbachia is the most frequent bacterial endosymbiont of arthropods and nematodes. Although it is mostly vertically transmitted, from parent to offspring through the egg cytoplasm, horizontal transfer of Wolbachia is thought to be common o…

Ghosts of symbionts past: the hidden history of the dynamic association between filarial nematodes and their <i>Wolbachia</i> endosymbionts Open
Many, but not all, parasitic filarial nematodes (Onchocercidae) carry intracellular, maternally transmitted, alphaproteobacterial Wolbachia symbionts. The association between filarial nematodes and Wolbachia is often portrayed as mutualist…

Genomic regions of current low hybridisation mark long-term barriers to gene flow in scarce swallowtail butterflies Open
Many closely related species continue to hybridise after millions of generations of divergence. However, the extent to which current patterning in hybrid zones connects back to the speciation process remains unclear: does evidence for curr…

Ghosts of symbionts past: The hidden history of the dynamic association between filarial nematodes and their<i>Wolbachia</i>endosymbionts Open
Many, but not all, parasitic filarial nematodes (Onchocercidae) carry intracellular, maternally-transmitted Wolbachia symbionts, and these alphaproteobacteria are targets for anti-filarial chemotherapeutic interventions for human disease. …

Genomic analyses in <i>Drosophila</i> do not support the classic allopatric model of speciation Open
The allopatric model of speciation has dominated our understanding of speciation biology and biogeography since the Modern Synthesis. It is uncontroversial because reproductive isolation may readily emerge as a by-product of evolutionary d…

Chromosomal Inversions and the Demography of Speciation in <i>Drosophila montana</i> and <i>Drosophila flavomontana</i> Open
Chromosomal inversions may play a central role in speciation given their ability to locally reduce recombination and therefore genetic exchange between diverging populations. We analyzed long- and short-read whole-genome data from sympatri…

Demographically explicit scans for barriers to gene flow using gIMble Open
Identifying regions of the genome that act as barriers to gene flow between recently diverged taxa has remained challenging given the many evolutionary forces that generate variation in genetic diversity and divergence along the genome, an…

Inferring inter-chromosomal rearrangements and ancestral linkage groups from synteny Open
Chromosome rearrangements shape the structure of the genome and influence evolutionary processes. Inferring ancestral chromosomes and rearrangements across a phylogenetic tree is therefore an important analysis within evolutionary genetics…
