Genetic relatedness cannot explain social bonds in black-and-white ruffed lemurs (Varecia variegata)

It is found that dyadic ruffed lemur social associations were generally sparse and weak; that home range overlap was minimal; and that average relatedness within the community was low, suggesting that other social, ecological, and biological factors such as shared resource defense or communal breeding might also play a role in social attraction.

Maternal lineages best explain the associations of a semisocial marsupial

The way social behaviors may be shaped by how kin selection and fine-scale spatial genetic structure interact is demonstrated.

Kinship and reproductive condition correlate with affiliation patterns in female southern Australian bottlenose dolphins

Female dolphins formed preferred associations and social clusters which ranged from overlapping to discrete home ranges, and matrilineal kinship and biparental relatedness, as well as reproductive condition, correlated with the strength of female affiliations.

Age proximity influences herd composition in wild giraffe

It is suggested that giraffe have evolved mechanisms for fostering the formation of social associations with similar aged non-kin, and for the first time that calves born into the same cohort have stronger social associations than calvesBorn into different age cohorts, and that the strength of their association is independent of the strengthof maternal associations.

Sex-specific association patterns in bonobos and chimpanzees reflect species differences in cooperation

Comparing sex-specific association patterns in chimpanzees and bonobos, which differ in the level of between-group competition and in the degree to which sex and kinship influence dyadic cooperation, finds clear species differences in association patterns.

Evaluating the influence of ecology, sex and kinship on the social structure of resident coastal bottlenose dolphins

The study emphasizes that stable isotope analysis is a promising tool to investigate the link between social structure and ecological specializations, particularly in taxa that are difficult to observe in the wild.

Kinship does not predict the structure of a shark social network

The role of genetic relatedness in shaping the social structure of adult shark populations has never been investigated and the lack of parental care in this species may contribute to the breakdown of family links in the population early in life, thereby preventing the formation of kin-based social networks.



Herd composition, kinship and fission–fusion social dynamics among wild giraffe

It is suggested that giraffe herds share many characteristics of fission–fusion social systems and propose that sophisticated communication systems are a crucial component regulating subgroup dynamics.

Sociogenetic structure, kin associations and bonding in delphinids

It is proposed that sexual conflict favoured the formation of these stable societies and in turn facilitated the development of kin‐biased behaviours in delphinid social systems.

Heterogeneous social associations within a sperm whale, Physeter macrocephalus, unit reflect pairwise relatedness

It is found that the patterns of association among members of this unit were heterogeneous and that individuals had preferred associations or avoidances with specific individuals, which indicate intra-unit social complexity, a basis for which seems to be genetic relatedness.

The ties that bind: genetic relatedness predicts the fission and fusion of social groups in wild African elephants

It is found that genetic relatedness predicted group fission; adult females remained with their first order maternal relatives when core groups fissioned temporarily, and relatedness also predicted temporary fusion between social groups.

Genetic relationships between roost-mates in a fission–fusion society of tree-roosting big brown bats (Eptesicus fuscus)

Kin-based patterns of associations are often observed in group living mammals. Colonies of forest-living big brown bats (Eptesicus fuscus) exhibit fission–fusion roosting behavior and female

Rank-related partner choice in the fission–fusion society of the spotted hyena (Crocuta crocuta)

It was found that subordinates who initiated group formation benefited by gaining social and feeding tolerance from dominants, and rates at which dominants provided coalitionary support to subordinates did not vary with AIs, which resemble patterns of association among cercopithecine primates.
