Examination of the cause-effect relationship between queen mating frequency and worker policing indicates that worker policing is caused by queen polyandry but thatworker policing is unlikely to cause polyandries, although it may help stabilize it if police workers show behavioral dominance.
Conflict resolution in insect societies.
Five major areas of reproductive conflict in insect societies are reviewed: (a) sex allocation, (b) queen rearing, (c) male rearing), (d) queen-worker caste fate, and (e) breeding conflicts among totipotent adults.
Paternity in eusocial Hymenoptera
It is concluded that reliably documented high paternity or insemination frequencies (> 2) are currently restricted to one phylogenetically isolated and highly eusocial taxon each in ants, eussocial bees and wasps (Atta, Apis and Vespula, respectively).
Ancestral Monogamy Shows Kin Selection Is Key to the Evolution of Eusociality
It is found that mating with a single male, which maximizes relatedness, is ancestral for all eight independent eusocial lineages that are investigated, and monogamy was critical in the evolution of eussociality, strongly supporting the prediction of inclusive fitness theory.
Task partitioning in insect societies
The data show that task partitioning occurs in many species, with examples in ants, bees, wasps, and termites, and that it is an important and widespread feature of work organisation in insect societies.
Worker policing in the honeybee
Experiments showing strong discrimination by honeybee (Apis mellifera) workers against worker-laid male eggs are described, supporting the worker-policing hypothesis.
An evolutionary ecology of individual differences.
It is concluded that a complete understanding of evolutionarily and ecologically relevant individual differences must specify how ecological interactions impact the basic biological process (e.g. Darwinian selection, development and information processing) that underpin the organismal features determining behavioural specialisations.
Long-range foraging by the honey-bee, Apis mellifera L.
Waggle dances of honey-bees were decoded to determine where and how far the bees foraged during the blooming of heather in August 1996 using a hive located in Sheffield, UK, east of the heather moors.
Conflict in single-queen hymenopteran societies : the structure of conflict and processes that reduce conflict in advanced eusocial species
Kin conflict over caste determination in social Hymenoptera
It is argued that caste determination, the process whereby females in the social Hymenoptera develop into either queens or workers, is subject to kin-selected conflict, and two contexts leading to potential caste conflict are suggested.
