Behavioural and hormonal correlates of cooperation in female Norway rats
Norway rats (Rattus norvegicus) are social animals that live in large colonies of both related and unrelated individuals. Especially females show complex social behaviour, including allogrooming, communal nursing, as well as food hoarding and sharing. Using a manual food-exchange task, we previously showed that female rats differ in their propensity to cooperate according to previous social experiences. Particularly, they provide help to a partner from which they have received help before (direct reciprocity) and are in general more cooperative to any individual after experiencing help by a conspecific (generalised reciprocity).
Currently, we investigate different modalities of reciprocal cooperation, as well as their connectivity with behavioural syndromes ("personality"), hormon levels (oxytocin, dopamin) and genetic background. For our projects, we house 160 male and female wild-type Norway rats in groups of same-sex sibling with which we test different forms of reciprocity and investigating their potental proximate and ultimate mechanisms.
