Adaptive introgression between two Drosophila species enhances heat tolerance despite barriers to gene flow

This study shows that strong heat stress selection can overcome genetic barriers to introgression between two Drosophila species, enhancing heat tolerance.

Hybrid breakdown is temporary and not expressed in a novel environment during 50 generations of experimental evolution in Tetranychus urticae hybrids

This study tracks hybrid fitness in Tetranychus urticae over 50 generations, showing initial incompatibilities resolve and hybrids gain adaptive potential in novel environments.

Introgression and divergence in a young species group

This study analyzes genomic patterns of divergence and introgression in five wood ant species to understand speciation processes and the role of gene flow and reproductive isolation.

Genomic incompatibilities are persistent barriers when speciation happens with gene flow in Formica ants

The paper identifies genomic barriers to gene flow between two wood ant species despite ongoing hybridization, revealing persistent incompatibilities and their functional implications.

The loss of a supergene in obligately polygynous Formica wood ant species

The paper investigates the loss of a supergene haplotype in obligately polygynous Formica ants using comparative genomics and finds that the derived haplotype P is absent in two species except for duplicated paralogs of specific genes.

Evidence for climate-mediated range expansion of hybrid wood ants

This study shows that hybrid wood ants outperform their parent species in warming climates and have expanded their range northward due to climate change.

Genetic modification of the ant Lasius niger using CRISPR-Cas9 technology

This study develops a CRISPR-Cas9 protocol for the ant Lasius niger to create targeted mutations in the eye pigmentation gene cinnabar, resulting in abnormal eye coloration.

Cost-effective long-read assembly of a hybrid Formica aquilonia x Formica polyctena wood ant genome from a single haploid individual

The paper assembles a high-quality genome of a hybrid Formica ant using long-read sequencing from a single individual, achieving high BUSCO completeness and enabling genomic studies of hybridization.

Temperature fluctuations between years predict temporal allele frequency variation in a hybrid ant population

The paper shows that temperature fluctuations predict allele frequency changes in male hybrids of Formica ants, but not females, suggesting sex-specific effects of hybridization on genetic variability.
