Abstract

Helpers in cooperative breeders support the dominants in raising offspring. Such support is expected to be task dependent and to increase breeders’ current or future reproductive success. We show that breeder females adjust their workload depending on the task in a cooperatively breeding fish by reducing their territory defense and broodcare according to the received help. However, they consistently showed the same amount of territory maintenance, indicating both load-lightening and additive effects taking place.
