Enhanced social learning between siblings in common ravens, Corvus corax
It has been suggested that social dynamics affect social learning but empirical support for this idea is scarce. Here we show that affiliate relationships among kin indeed enhance the performance of common ravens, Corvus corax, in a social learning task. Via daily behavioural protocols we first monitored social dynamics in our group of captive young […]
Relationship with the mother modulates the response of yearling Japanese macaques (Macaca fuscata) to the birth of a sibling
The authors investigated the changes induced by the birth of a sibling in the relationship of 1-year-old Japanese macaques (Macaca fuscata) with their mothers and group companions. After the birth of a sibling, mother-yearling contact, proximity, and grooming decreased dramatically. Yearlings responded to such a reduction in maternal care in either of 2 radically different […]
Mothers and offspring: The rabbit as a model system in the study of mammalian maternal behavior and sibling interactions
This article is part of a Special Issue “Parental Care”. Jay Rosenblatt effectively promoted research on rabbit maternal behavior through his interaction with colleagues in Mexico. Here we review the activities of pregnant and lactating rabbits (Oryctolagus cuniculus), their neuro-hormonal regulation, and the synchronization of behavior between mother and kits. Changing concentrations of estradiol, progesterone, […]
