Dominance interactions determine reproductive status in many animal societies, including many cooperatively breeding vertebrates and eusocial Hymenoptera without queen-worker dimorphism. Typically, the dominant individual monopolises reproduction, and subordinates behave like helpers. In Dinoponera queenless ants, workers are totipotent females and can potentially reproduce, yet only the top-ranking worker actually reproduces. Individual workers ranked immediately below the dominant breeder… 
The build-up of dominance hierarchies in eusocial insects
TLDR
It is described how the emergence of dominance hierarchies can be understood as a kind of self-organizing process through individual memory and local behavioural interactions, and how the resulting global structures can be captured by using network analyses.
Built to change: dominance strategy changes with life stage in a primitively eusocial bee
TLDR
It is found that the queens’ strategy to monopolize reproduction changes with life stage, shifting from overt aggression to chemical signalling as the queen gets older, contributing to the understanding of reproductive dominance in the context of an individual’s life history.
No actual conflict over colony inheritance despite high potential conflict in the social wasp Polistes dominulus
TLDR
Using patterns of egg-laying and egg destruction, it is shown in 32 laboratory colonies that, upon the removal of alpha, workers fully accepted a subordinate as the new breeder, and there was no increase in reproduction by workers and other subordinates.
Crossing the taxonomic divide: conflict and its resolution in societies of reproductively totipotent individuals
TLDR
It is found that premature replacement of a parent breeder by nonbreeders (overthrow) is rare and honest signalling of breeder vitality can maintain group stability and resolve conflicts over reproduction.
Division of labour and risk taking in the dinosaur ant, Dinoponera quadriceps (Hymenoptera: Formicidae)
TLDR
It is suggested that both risk-taking and egg-care behaviours are related to future reproductive prospects in D. quadriceps, a species with relatively simple societies, and a mechanism by which effective division of labour could have been achieved during the early stages of eusocial evolution.
Conflict over the timing of breeder replacement in vertebrate and invertebrate societies
TLDR
This cross-taxonomic review reveals that some non-breeders attempt to replace the breeder or position themselves so as to be able to do so when the opportunity arises, which supports the predictions of the model.
Evolution of wingless reproductives in ants: weakly specialized ergatoid queen instead of gamergates in Platythyrea conradti
TLDR
Gamergates and ergatoid queens are two mutually redundant reproductive phenotypes that allow colonial reproduction by fission in Platythyrea conradti.
Group Size in Animal Societies: The Potential Role of Social and Ecological Limitations in the Group‐Living Fish, Paragobiodon xanthosomus
TLDR
The relationships between resource availability, social conflict, and group size in the coral-dwelling fish, Paragobiogon xanthosomus (Gobiidae) are examined, suggesting that group size may be limited by the social conflicts that characterize size-based dominance hierarchies.
A novel method of assessing dominance hierarchies shows nuance, linearity and stability in the dinosaur ant Dinoponera quadriceps
TLDR
The isolated dya-dic interaction method using the queenless dinosaur ant Dinoponera quadri-ceps showed the hierarchies to be highly linear and stable, and revealed that dominance relationships may extend further down the hierarchythan previously thought.
Global network structure of dominance hierarchy of ant workers
TLDR
It is shown that the observed dominance networks in Diacamma sp.

Dominance hierarchy and reproductive conflicts among subordinates in a monogynous queenless ant
TLDR
The relative importance of chemical communication and dominance interactions to regulate reproduction is investigated and Alpha, beta, and sterile workers have different signatures of cuticular hydrocarbons, and these may provide honest information which underpins worker policing by low-ranking individuals.
Dominance and queen succession in captive colonies of the eusocial naked mole–rat, Heterocephalus glaber
TLDR
The intense dominance–related aggression that accompanies reproductive succession in naked mole–rats provides empirical support for optimal skew theory.
Worker's age regulates the linear dominance hierarchy in the queenless ponerine ant, Pachycondyla sublaevis (Hymenoptera: Formicidae)
TLDR
It is suggested that the dominance hierarchy of this ant species has evolved as a consequence of intra-colonial competition for reproduction.
Dominance Interactions Regulate Worker Mating in the Polygynous Ponerine Ant Gnamptogenys menadensis
TLDR
The probability of mating is regulated by dominance interactions among workers and immobilizations initiated by infertile workers in this polygynous queenless ant.
A linear dominance hierarchy regulating reproduction and polyethism of the queenless antPachycondyla sublaevis
TLDR
In the queenless ant Pachycondyla (= Bothroponera) sublaevis, this is the first discovery of dominance hierarchy in which most members of a colony are potential successors of the reproductive female.
New colony formation in the “highly inbred” eusocial naked mole-rat: outbreeding is preferred
TLDR
It is shown that in laboratory colonies in which each individual had an equal number of familiar siblings and unfamiliar distant kin (UDK) as potential mates, mating pairs were significantly more likely to consist of UDK.
Serial polygyny and colony genetic structure in the monogynous queenless ant Diacamma cyaneiventre
TLDR
The rate of gamergate turnover relative to the rate of worker turnover is shown to be the crucial parameter determining the level of serial polygyny and its effect on the genetic structure of colonies in D. cyaneiventre.
Dominance, access to colonies, and queues for mating opportunities by male boat-tailed grackles
  • J. Poston
  • Biology

TLDR
Male boat-tailed grackles (Quiscalus major) compete for access to colonies of females and form linear dominance hierarchies, which represent queues for mating opportunities.
Monogyny and regulation of worker mating in the queenless ant Dinoponera quadriceps
TLDR
Comparison evidence indicates that worker mating is often regulated in monogynous species, while unrestricted mating of young individuals is typical of polygynous species (oviposition is regulated subsequently).
Policing in queenless ponerine ants
TLDR
This work reviews worker and "queen" policing in queenless ponerine ants and extends the definition of policing to include species, such as queenless ants, where females are totipotent, thereby including not only conflict over male production but also over gamergate replacement and gamergate number.
