Epigenetic and genetic differentiation between Coregonus species pairs

The paper examines genetic and epigenetic differentiation between sympatric benthic-limnetic whitefish species pairs, finding evidence that DNA methylation contributes to mutagenesis and genetic divergence during speciation.

Searching for intra-locus sexual conflicts in the three-spined stickleback (Gasterosteus aculeatus) genome

The paper investigates intra-locus sexual conflicts in three-spined sticklebacks using whole genome sequencing and detects four genomic regions associated with balancing selection, suggesting most conflicts are transient but may locally reduce purifying selection.

A supergene in seaweed flies modulates male traits and female perception

The paper investigates how the Cf-Inv(1) supergene in seaweed flies influences male chemical traits and female perception, supporting disassortative mating through linked genetic mechanisms.

A large chromosomal inversion shapes gene expression in seaweed flies (Coelopa frigida)

This study examines how the Cf-Inv(1) chromosomal inversion in seaweed flies affects gene expression across sexes and life stages, identifying candidate variants that may influence adaptive traits.

Genome-wide DNA methylation predicts environmentally-driven life history variation in a marine fish

This study shows that DNA methylation patterns differ between two life history strategies in capelin, suggesting epigenetic changes, not genetic differences, drive these variations.

Locally-adaptive inversions modulate genetic variation at different geographic scales in a seaweed fly

This study examines how chromosomal inversions influence genetic variation across geographic scales in the seaweed fly, finding they differentiate populations more strongly than collinear regions.

Classic and introgressed selective sweeps shape mimicry loci across a butterfly adaptive radiation

The paper analyzes genome sequences from Heliconius butterflies to show selection on color pattern loci, identifying both classic and introgressed selective sweeps.

Balancing selection via life-history trade-offs maintains an inversion polymorphism in a seaweed fly

The paper shows that a chromosomal inversion in seaweed flies is maintained by life-history trade-offs and antagonistic pleiotropy, revealing balancing selection mechanisms.

Karyotype-environment associations support a role for a chromosomal inversion in local adaptation among North American populations of the seaweed fly Coelopa frigida

The paper investigates a chromosomal inversion in Coelopa frigida, finding it polymorphic in North America and associated with environmental factors and adult size.

What shapes the continuum of reproductive isolation? Lessons from Heliconius butterflies.

This study examines reproductive isolation in Heliconius butterflies, finding that increased divergence leads to stronger barriers, with wing pattern being important early on but not essential for speciation.
