“…Concession models predict that skew should positively correlate with relatedness between potential reproductives (Vehrencamp 1983a;Reeve & Ratnieks 1993;Reeve & Keller 1997). In line with this prediction, we found that queen relatedness is higher in the functionally monogynous population than in polygynous populations (Chan & Bourke 1994;Heinze 1995;Hammond et al 2001Hammond et al , 2006.…”

Identifying species exhibiting variation in social organization is an important step towards explaining the genetic and environmental factors underlying social evolution. In most studied populations of the ant Leptothorax acervorum, reproduction is shared among queens in multiple queen colonies (polygyny). By contrast, reports from other populations, but based on weaker evidence, suggest a single queen may monopolize all reproduction in multiple queen colonies (functional monogyny). Here we identify a marked polymorphism in social organization in this species, by conclusively showing that functional monogyny is exhibited in a Spanish population, showing that the social organization is stable and not purely a consequence of daughter queens overwintering, that daughter queen re-adoption is frequent and queen turnover is low. Importantly, we show that polygynous and functionally monogynous populations are not genetically distinct from one another based on mtDNA and nDNA. This suggests a recent evolutionary divergence between social phenotypes. Finally, when functionally monogynous and polygynous colonies were kept under identical laboratory conditions, social organization did not change, suggesting a genetic basis for the polymorphism. We discuss the implications of these findings to the study of reproductive skew.

“…These models start from the premise that aggression is used by dominants to suppress reproduction in subordinates and by subordinates to claim a share of reproduction from dominants. For example, the transactional model of Reeve and Keller (1997) shows that it will always pay a dominant individual to appease a potential challenger by offering it a share of reproduction. By contrast, the tug-of-war model assumes that the distribution of reproduction is the outcome of a scramble competition in which the dominant individual exerts a stronger "tug" (Reeve et al 1998;Cant and Shen 2006).…”

Recent theory suggests that much of the wide variation in individual behavior that exists within cooperative animal societies can be explained by variation in the future direct component of fitness, or the probability of inheritance. Here we develop two models to explore the effect of variation in future fitness on social aggression. The models predict that rates of aggression will be highest toward the front of the queue to inherit and will be higher in larger, more productive groups. A third prediction is that, in seasonal animals, aggression will increase as the time available to inherit the breeding position runs out. We tested these predictions using a model social species, the paper wasp Polistes dominulus. We found that rates of both aggressive "displays" (aimed at individuals of lower rank) and aggressive "tests" (aimed at individuals of higher rank) decreased down the hierarchy, as predicted by our models. The only other significant factor affecting aggression rates was date, with more aggression observed later in the season, also as predicted. Variation in future fitness due to inheritance rank is the hidden factor accounting for much of the variation in aggressiveness among apparently equivalent individuals in this species.

“…By contrast, concession models set a lower limit on the share of direct reproduction that subordinates will acquire. Even if the dominant has complete control over the allocation of reproduction within the group (as existing concession models in fact assume), it must yield a share at least as great as thè staying incentive' of Reeve & Ratnieks (1993) to avert the threat of subordinate departure (see Reeve & Keller 1997).…”

Most recent models of the partitioning of reproduction attempt to explain patterns of skew on the assumption that dominant individuals have complete control over breeding opportunities within the group, but may nevertheless concede a share of direct reproduction to subordinates as an incentive to remain peacefully in the association. Although these models may be applicable to some animal societies, we argue that they fail to provide a comprehensive theory of skew. Instead, we suggest that subordinates may often be able to claim unsanctioned reproduction for themselves, but will be forced to exercise a degree of reproductive restraint lest they incite ejection by the dominant. Reproductive skew, in other words, may re£ect the threat of ejection (inducing subordinate restraint) rather than the threat of subordinate departure (inducing reproductive concessions by dominants). We present a simple evolutionarily stable strategy model of reproductive skew under these circumstances, which demonstrates that a shift in emphasis from reproductive concessions by dominants to reproductive restraint on the part of subordinates, radically alters the predictions of skew models. High group productivity, high relatedness and (when group members are related) strong ecological constraints are all expected to lead to reduced skew (the opposite conclusions to those of previous, concession-based analyses). The reason is that these factors reduce the bene¢ts (or increase the costs) of ejection to the dominant, who therefore does best to tolerate more subordinate reproduction.
