Inversions are structural mutations that reverse the sequence of a chromosome segment
and reduce the effective rate of recombination in the heterozygous state. They play a major …

▪ Abstract Invasions by non-native ants are an ecologically destructive phenomenon
affecting both continental and island ecosystems throughout the world. Invasive ants often …

Intraspecific variability in social organization is common, yet the underlying causes are
rarely known,,. In the fire ant Solenopsis invicta, the existence of two divergent forms of …

Colony queen number, a major feature of social organization in fire ants, is associated with
worker genotypes at the gene Gp-9. We sequenced Gp-9 and found that it encodes a …

Ants are among the most widespread and damaging of introduced species. Many invasive
ants share a suite of characteristics that facilitate their introduction, establishment, and …

Species commonly exhibit alternative morphs, with individual fate being determined during
development by either genetic factors, environmental cues or a combination thereof. Ants …

Molecular genetic studies of group kin composition and local genetic structure in social
organisms are becoming increasingly common. A conceptual and mathematical framework …

Supergenes are clusters of linked genetic loci that jointly affect the expression of complex
phenotypes, such as social organization. Little is known about the origin and evolution of …

Variation in social behaviour is common, yet little is known about the genetic architectures
underpinning its evolution. A rare exception is in the fire ant Solenopsis invicta: Alternative …

Landscape corridors are commonly used to mitigate negative effects of habitat
fragmentation, but concerns persist that they may facilitate the spread of invasive species. In …
