The study of social parasitism faces numerous challenges arising from the intricate and
intranidal host–parasite interactions and the rarity of parasites compared to their free-living …

Antagonistic selection has long been considered a major driver of the formation and
expansion of sex chromosomes. For example, sexually antagonistic variation on an …

Ants exhibit many complex social organization strategies. One particularly elaborate strategy
is supercoloniality, in which a colony consists of many interconnected nests (= polydomy) …

Abstract Models of both sex chromosome evolution and the genetic basis of local adaptation
suggest that selection acts to lock beneficial combinations of alleles together in regions of …

Current genomic methods allow us to determine how genes shape phenotypic traits. Here,
we are interested in the genetic basis of body size variation in ants. To conduct this …
