Brain organization mirrors caste differences, colony founding and nest architecture in paper wasps (Hymenoptera: Vespidae).
The cognitive challenges that social animals face depend on species differences in social organization and may affect mosaic brain evolution. We asked whether the relative size of functionally distinct brain regions corresponds to species differences in social behaviour among paper wasps (Hymenoptera: Vespidae). We measured the volumes of targeted brain regions in eight species of paper wasps. ...
متن کاملCorrelated evolution of colony defence and social structure: A comparative analysis in eusocial wasps (Hymenoptera: Vespidae)
Animal societies depend on effective defence of group resources. Defensive mechanisms can be costly and may constrain the evolution of social structure. We analysed how exocrine mechanisms of colony defence were affected by the evolution of social complexity and of nest architecture in paper wasps (Vespidae). Eusocial paper wasp species exhibit two discrete grades of eusociality, with new colon...
متن کاملDistributed cognition and social brains: reductions in mushroom body investment accompanied the origins of sociality in wasps (Hymenoptera: Vespidae).
The social brain hypothesis assumes the evolution of social behaviour changes animals' ecological environments, and predicts evolutionary shifts in social structure will be associated with changes in brain investment. Most social brain models to date assume social behaviour imposes additional cognitive challenges to animals, favouring the evolution of increased brain investment. Here, we presen...
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 کاملCastes and asynchronous colony cycle in Polybia bistriata (Fabricius) (Hymenoptera: Vespidae).
Neotropical swarm-founding wasps, the Epiponini, are an outstanding group of social insects whose societies are polygynic and complex nest builders. Caste dimorphism in these wasps ranges from incipient to highly distinct. Morphometric analyses of nine body parts, ovarian status, relative age and development of the 5th gastral sternite gland (Richards' gland) of Polybia bistriata Fabricius were...
