Early social and ecological experience triggers divergent reproductive investment strategies in a cooperative breeder

Abstract Unlike eusocial systems, which are characterized by reproductive division of labour, cooperative breeders were predicted not to exhibit any reproductive specialization early in life. Nevertheless, also cooperative breeders face a major life-history decision between dispersal and independent...
