Reproductive hierarchies in the African allodapine bee Allodapula dichroa (Apidae: Xylocopinae) and ancestral forms of sociality
The social organization of allodapine bees has been described in detail for most genera, although there remains a notable gap for one major lineage, the genus Allodapula. Here, we provide the first detailed study of social organization in Allodapula dichroa. Colony sizes are small and the frequency of cooperative nesting is low compared with other allodapine taxa, but there is very clear eviden...

Uneven sharing of reproduction (reproductive skew) among members of a cooperative animal society is one of the key features associated with advanced sociality and task specialization. Allocation of reproduction varies greatly among taxa, and reproductive skew models are evolutionary models that aim at explaining this variation. We tested reproductive skew theory using the Australian social allo...
