The paper quantifies introgression in 4126 ant colonies, finding 23% of species show introgression, more than double previous estimates, and suggests postzygotic barriers constrain it.

The paper tests if Wolbachia induces parthenogenesis in ladybugs by reducing Wolbachia load with antibiotics, showing decreased reproduction in parthenogenetic females.

The study examines whether morphologically distinct Myrmica ant species are reproductively isolated using genetic data, finding high congruence between morphology and genetic lineage.

The paper develops a decontamination pipeline to detect and remove contamination in genomic data, revealing rare introgression in Lasius ants.
