Rewinding the ratchet: rare recombination locally rescues neo-W degeneration and generates plateaus of sex-chromosome divergence

The paper studies neo-sex chromosome evolution in butterflies, finding that rare recombination can reverse degradation and create divergence plateaus on neo-W chromosomes.

Inferring inter-chromosomal rearrangements and ancestral linkage groups from synteny

The paper implements and evaluates algorithms for inferring ancestral linkage groups and inter-chromosomal rearrangements using synteny, showing their effectiveness and limitations with simulations and nematode genome data.

Do chromosome rearrangements fix by genetic drift or natural selection? A test in Brenthis butterflies

The paper investigates whether chromosome rearrangements in Brenthis butterflies fix via genetic drift or natural selection, finding evidence for both mechanisms.

Chromosome evolution in Lepidoptera

The paper analyzes 210 lepidopteran genomes to show that chromosome diversity arises from 32 ancestral linkage groups, with eight lineages undergoing extensive reorganization.

Chromosome fissions and fusions act as barriers to gene flow between Brenthis fritillary butterflies

This study shows chromosome fissions and fusions reduce gene flow between sympatric Brenthis fritillary butterflies by lowering effective migration rates in rearranged genomic regions.

The genome sequence of the scarce swallowtail, Iphiclides podalirius

This paper presents a chromosome-level genome assembly for the scarce swallowtail butterfly and reports a negative correlation between chromosome length and heterozygosity at fourfold-degenerate sites.

The genome sequence of the lesser marbled fritillary, Brenthis ino, and evidence for a segregating neo-Z chromosome

This paper presents a chromosome-level genome assembly for the lesser marbled fritillary, Brenthis ino, and provides evidence for a segregating neo-Z chromosome in males.

Inversions maintain differences between migratory phenotypes of a songbird

The paper identifies inversions in three divergent genomic regions associated with migratory differences in willow warblers, suggesting a role in maintaining phenotypic divergence.
