According to behavioural ecology theory, sociality evolves when the net benefits of close
association with conspecifics exceed the costs. The nature and relative magnitude of the …

Spotted hyenas (Crocuta crocuta) are large mammalian carnivores, but their societies,
called 'clans', resemble those of such cercopithecine primates as baboons and macaques …

Virtually nothing in nature is uniform. Observed at the right scale, most entities are clustered
rather than evenly distributed, spatially and temporally, and this applies across domains …

Kin selection can explain the evolution of cooperative breeding and the distribution of
relatives within a population may influence the benefits of cooperative behaviour. We …

Traffic collisions can be a major source of mortality in wild populations, and animals may be
expected to exhibit behavioral mechanisms that reduce the risk associated with crossing …

Behavioural observations suggest that orang‐utans are semi‐solitary animals with females
being philopatric and males roaming more widely in search of receptive partners, leading to …

The maned wolf Chrysocyon brachyurus is a nocturnal and shy species, which has proven
difficult to study in the field; consequently, data about its behavioural biology are almost …

The Canidae are successful, being a widespread, abundant, speciose, and adaptable
family. Several canids in particular have recently experienced rapid expansions in range …

Cooperative breeding (ie when alloparents care for the offspring of other group members)
has been studied for nearly a century. Yet, inconsistent definitions of this breeding system …

Male-biased sexual size dimorphism is typical of polygynous mammals, where the degree of
dimorphism in body mass is related to male intrasexual competition and the degree of …
