Genetic basis of cuticular hydrocarbon variation in the desert ant Cataglyphis niger

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

Repeated evolution of supergenes on an ancient social chromosome

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

Evaluating the applicability of kinship analyses for sedimentary ancient DNA datasets

This study evaluates kinship inference in sedimentary ancient DNA by simulating data and applying a heterozygosity-based test to identify multi-contributor samples.

Comparative study of population genomic approaches for mapping colony-level traits

This study compares genomic approaches for mapping colony-level traits, finding that whole-genome pool-seq provides greater QTL detection power than reduced representation pool-seq.
