Alloparental care in glassfrogs: males care for unrelated clutches only when associated with their own

Abstract Parental care is costly, thus theory predicts that parents should avoid caring for unrelated offspring. However, alloparenting has been reported in many taxa because it may increase the caregiver mating success or offspring survival. We experimentally investigated the existence of allopater...
