The paper identifies large-scale genomic rearrangements in the J1 lineage of Pogonomyrmex barbatus that may explain reproductive isolation in the dependent-lineage system.

The paper analyzes ant odorant receptor evolution across 163 genomes to link adaptive changes in ORs to sociobiological traits like colony size and worker polymorphism.

This study identifies genetic loci associated with cuticular hydrocarbon variation in the desert ant Cataglyphis niger, revealing a polygenic architecture underlying chemical signaling traits.

This paper identifies a new supergene in desert ants associated with social polymorphism, showing that social chromosomes are ancient and conserved across Hymenoptera.

The paper develops a reconciliation-based method to detect positive selection in multi-copy gene families, identifying adaptive patterns in ant odorant receptor repertoires.
