Hyena clan rank metrics need to be trait specific to fully explain hierarchies, scientists argue

Spotted hyenas live in hierarchically organized groups (clans). An individual’s dominance over another determines priority access to resources such as food or mating partners, and thus reproductive success. However, the rank within the clan can be calculated using different metrics—and that matters. Using data from almost 500 hyenas collected over 28 years, scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) showed that different metrics best predict the animals’ reproductive success—depending on which reproductive trait they examined.
