Spotted hyenas (Crocuta crocuta) are large mammalian carnivores, but their
societies, called ‘clans,’ resemble those of such cercopithecine primates
as baboons and macaques with respect to their size, hierarchical
structure, and frequency of social interaction among both kin and
unrelated group-mates. However, in contrast to cercopithecine primates,
spotted hyenas regularly hunt antelope and compete with group-mates for
access to kills, which are extremely rich food sources, but also rare and
ephemeral. This unique occurrence of baboon-like sociality among top-level
predators has favored the evolution of many unusual traits in this
species. We briefly review the relevant socio-ecology of spotted hyenas,
document great demographic variation but little variation in social
structure across the species’ range, and describe the long-term fitness
consequences of rank-related variation in resource access among
clan-mates. We then summarize patterns of genetic relatedness within and
between clans, including some from a population that had recently gone
through a population bottleneck, and consider the roles of sexually
dimorphic dispersal and female mate choice in the generation of these
patterns. Finally, we apply social network theory under varying regimes of
resource availability to analyze effects of kinship on the stability of
social relationships among members of one large hyena clan in Kenya.
Although social bonds among both kin and non-kin are weakest when resource
competition is most intense, hyenas sustain strong social relationships
with kin year-round, despite constraints imposed by resource limitation.
Our analyses suggest that selection might act on both individuals and
matrilineal kin groups within clans containing multiple matrilines.
