Optimal reproductive-skew models fail to predict aggression in wasps.
Optimal-skew models (OSMs) predict that cooperative breeding occurs as a result of dominants conceding reproductive benefits to subordinates, and that division of reproduction within groups reflects each cooperator's willingness and ability to contest aggressively for dominance. Polistine paper wasps are a leading model system for testing OSMs, and data on reproduction and aggression appear to ...
متن کاملNatural History of Tropical Parasitoid Wasps
The order Hymenoptera currently includes the impressive number of more than 115000 known species. The tropical hymenopteran fauna, however, is poorly known and this number probably represents just a small fraction of the real richness of the group. A great part of the species within Hymenoptera is composed of parasitoids, animals that exploit other organisms to death in order to acquire the foo...
متن کاملReproductive skew in the polygynandrous acorn woodpecker.
Reproductive skew models, which focus on the degree to which reproduction is shared equally (low skew) or monopolized by a single individual (high skew) within groups, have been heralded as providing a general unifying framework for understanding the factors determining social evolution. Here, we test the ability of optimal skew, or "transactional," models, which predict the level of skew neces...
متن کاملReproductive caste determination in eusocial wasps (Hymenoptera: Vespidae).
Wasps (Vespidae) exhibit a range of social complexity, from solitary living to eusocial colonies, and thus are exemplary for studies of the evolutionary origin and maintenance of social behavior in animals. Integral to the definition of eusociality is the presence of reproductive castes, group members that differ qualitatively in their ability to reproduce in a social setting. Behavioral and mo...
متن کاملA novel `sit and wait' reproductive strategy in social wasps
I present evidence indicating that a subset of spring females in the social wasp Polistes dominulus do not initiate colonies but rather s̀it and wait' to adopt colonies initiated and abandoned by other conspeci¢cs. These results are, to my knowledge, the ¢rst to demonstrate conclusively this alternative reproductive strategy in social wasps. Individuals engaging in the sit-and-wait strategy beha...
