Queen size mediates queen survival and colony fitness in harvester ants.
We examined the effect of queen size on the probability of new colony establishment in the ant Pogonomyrmex occidentalis. Large queens are significantly more likely to survive than small queens through the initial stages of colony founding. These differences in individual fitness correlates have corresponding effects on colony fitness. In species in which individual queens vary in fitness, sexu...
متن کاملPolygynous Ants: Ecological Repercussions of a Multi-queen Colony
Many recent studies of polygynous ants have focused on producing an ecological and reproductive cost-benefit analysis of polygynous systems in order to shed light on how or why it developed over the more common practice of monogyny. Polygyny, the practice of keeping multiple reproductive queens in one colony, has evolved in many ant species, some of which display both polygynous and monogynous ...
متن کاملExtreme queen-mating frequency and colony fission in African army ants.
Army ants have long been suspected to represent an independent origin of multiple queen-mating in the social Hymenoptera. Using microsatellite markers, we show that queens of the African army ant Dorylus (Anomma) molestus have the highest absolute (17.3) and effective (17.5) queen-mating frequencies reported so far for ants. This confirms that obligate multiple queen-mating in social insects is...
متن کاملColony fusion and worker reproduction after queen loss in army ants.
Theory predicts that altruism is only evolutionarily stable if it is preferentially directed towards relatives, so that any such behaviour towards seemingly unrelated individuals requires scrutiny. Queenless army ant colonies, which have anecdotally been reported to fuse with queenright foreign colonies, are such an enigmatic case. Here we combine experimental queen removal with population gene...
متن کاملColony genetic structure and queen mating frequency in fire ants of the subgenus Solenopsis (Hymenoptera: Formicidae)
Colony genetic structure was studied in natural populations of three fire ant taxa, Solenopsis richteri Forel, S. geminata (Fabr.), arid hybrid S. inuicta/richteri, using allozyme markers. All colonies studied exhibited arrays of femalc gcnotypes predicted under a model of monogyny (single functional queen) and monoandry (single insemination of queens). Males produced in the colonies appear to ...
