Social Evolution: Pathways to Ant Unicoloniality
نویسنده
چکیده
Unicolonial ant species live in interlinked populations known as super-colonies, where workers and queens move freely. New research suggests that low intra-specific resource competition leads to an absence of inter-colony aggression.

Dynamics and genetic structure of Argentine ant supercolonies in their native range.
Some introduced ant populations have an extraordinary social organization, called unicoloniality, whereby individuals mix freely within large supercolonies. We investigated whether this mode of social organization also exists in native populations of the Argentine ant Linepithema humile. Behavioral analyses revealed the presence of 11 supercolonies (width 1 to 515 m) over a 3-km transect. As in...
متن کاملNative supercolonies of unrelated individuals in the invasive Argentine ant.
Kinship among group members has long been recognized as a main factor promoting the evolution of sociality and reproductive altruism, yet some ants have an extraordinary social organization, called unicoloniality, whereby individuals mix freely among physically separated nests. This type of social organization is not only a key attribute responsible for the ecological dominance of these ants, b...
متن کاملUnicoloniality, recognition and genetic differentiation in a native Formica ant.
Some ants have an extraordinary form of social organization, called unicoloniality, whereby individuals mix freely among physically separated nests. This mode of social organization has been primarily studied in introduced and invasive ant species, so that the recognition ability and genetic structure of ants forming unicolonial populations in their native range remain poorly known. We investig...
متن کاملGo High or Go Low? Adaptive Evolution of High and Low Relatedness Societies in Social Hymenoptera
Cooperative groups can increase fitness either by helping kin or interacting with unlike individuals to produce social heterosis. They cannot, however, simultaneously maximize both benefits. This tradeoff between nepotism and diversity is modeled using Hamilton’s rule (rb–c > 0), by allowing benefit and cost to be dynamic functions of relatedness (i.e., social heterosis predicts b and c depend ...
متن کاملThe Guianese population of the fire ant Solenopsis saevissima is unicolonial.
In this study, conducted in French Guiana, a part of the native range of the fire ant Solenopsis saevissima, we compared the cuticular hydrocarbon profiles of media workers with previous results based on intraspecific aggressiveness tests. We noted a strong congruence between the two studies permitting us to delimit 2 supercolonies extending over large distances (up to 54 km), a phenomenon know...
