Aggression decreases as play emerges in infant spotted hyaenas: preparation for joining the clan
Article Abstract:
The spotted hyenas, Crocuta crocuta, exhibit prosocial behavior only after two to three weeks of age when intense aggression gives way to high-intensity social play. A study of the behavior of eight sets of captive hyena twins during the first month after birth reveals a significant decline in aggressive bite shakes during the first week. However, there are no changes in the other forms of aggression. Week one is characterized by low-intensity mother-cub prosocial behavior. Intense social play among siblings emerges in week two and frequent interactive play is observed in weeks three and four.

Acquisition of matrilineal rank in captive spotted hyaenas: emergence of a natural social system in peer-reared animals and their offspring
Article Abstract:
Matrilineal rank attainment, a primary characteristic of spotted hyaenas, develops in peer-reared animals irrespective of alterations in group compositions and social organizations. Six groups of mothers, cubs, and adults were studied. It was found that offsprings acquire ranks next to their mothers in response to feeding and agonistic behavior. No female dominance was observed before sexual maturity in groups of peer-reared animals. Group dominance was maintained in the absence of mothers and adults during the competitive and dyadic tests.

Faecal androgen concentrations in adult male spotted hyaenas, Crocuta crocuta, reflect interactions with socially dominant females
Article Abstract:
Research on a large clan of spotted hyenas in Kenya revealed no systematic influence of social status or age on fecal androgens for either adult immigrant or natal males. Findings suggest that androgen concentrations may be correlated with interactions with females; details are discussed.
