The paper identifies mitonuclear co-introgression in red-backed voles, showing adaptive mitochondrial introgression and avoidance of mitonuclear incompatibilities through co-introgression of nuclear-encoded mitochondrial genes.

The paper introduces triangulaR, an R package for identifying ancestry-informative markers and visualizing hybrid index and interclass heterozygosity as triangle plots using SNP data from hybrid zones.

This study shows that STRUCTURE and PCA alone cannot reliably distinguish admixture from isolation-by-distance, but triangle plots improve accuracy when used in combination.
