Kinship has been shown to be an important correlate of group membership and associations among many female mammals. In this study, we investigate association patterns in female Indo-Pacific bottlenose dolphins (Tursiops aduncus) inhabiting an embayment in southeastern Australia. We combine the behavioral data with microsatellite DNA and mitochondrial DNA data to test the hypotheses that genetic relatedness and maternal kinship correlate with associations and social clusters. Mean association… 
Patterns of association among female Indo-Pacific bottlenose dolphins (Tursiops aduncus) in a population forming large groups
Ass associations among 70 females suggest that even in a population with large group size, the reproductive status of females is one of the factors influencing their associations.
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.
Home range overlap, matrilineal and biparental kinship drive female associations in bottlenose dolphins
Home range overlap , matrilineal and biparental kinship drive female associations in bottlenose dolphins
Few studies of kinship in mammalian societies have been able to consider the complex interactions between home range overlap, association patterns and kinship, which have created a critical gap in
Groups of related belugas (Delphinapterus leucas) travel together during their seasonal migrations in and around Hudson Bay
It is shown that relatives other than strictly parents, and especially females, play a role in maintaining a social structure that could facilitate the learning of migration routes and cultural conservatism may limit contributions from nearby summer stocks to endangered stocks.
Complex Social Structure of an Endangered Population of Bottlenose Dolphins (Tursiops truncatus) in the Aeolian Archipelago (Italy)
Associations between dolphins were hierarchically structured, where two mixed-sex social units were subdivided into smaller temporarily dynamic groups, and most likely dolphins' social organization depends on a combination of socio-ecological, demographic and anthropogenic factors.
Environmental and social influences on the genetic structure of bottlenose dolphins (Tursiops aduncus) in Southeastern Australia
The results suggest that the scale of connectivity of bottlenose dolphin communities inhabiting heterogeneous environments is likely to be affected by local habitat adaptation, which has important implications for the management of communities exposed to increasing levels of anthropogenic disturbances.
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.
Spatial and Social Sexual Segregation Patterns in Indo-Pacific Bottlenose Dolphins (Tursiops aduncus)
Habitat use by female dolphin groups suggests that shallow tributaries may provide a sanctuary from aggressive males, access to suitable prey items and density for mothers and their calves, or a combination of these factors.


Alliance membership and kinship in wild male bottlenose dolphins (Tursiops aduncus) of southeastern Australia
Testing whether individually identified male bottlenose dolphins preferentially associate and form alliances with kin in a small coastal resident population of southeastern Australia indicated that mechanisms other than kin selection may be foremost in the development and maintenance of cooperation between male bottleneck dolphins.
Genetic evidence for sex‐biased dispersal in resident bottlenose dolphins (Tursiops aduncus)
The genetic data contradict the hypothesis of bisexual Philopatry to natal site and suggest that these bottlenose dolphins are not unusual amongst mammals, with females being the more philopatric and males the more dispersing sex.
Sex Differences in Patterns of Association Among Indian Ocean Bottlenose Dolphins
Patterns of association among bottlenose dolphins resident in Shark Bay, Western Australia were analyzed using party membership data and found male-female associations were generally inconsistent and depended in part on female reproductive state.
Flexible social structure of a desert rodent, Rhombomys opimus: philopatry, kinship, and ecological constraints
It is concluded that great gerbils are facultatively social and may be adaptive in unpredictable desert conditions because they live solitarily under conditions of limited food and high mortality that disrupt social behavior and group formation.
Relatedness structure and kin-biased foraging in the greater horseshoe bat (Rhinolophus ferrumequinum)
The results suggest that inclusive fitness benefits may only be accrued through discriminate cooperation within matrilines, and not at the wider colony level.
Reproductive success increases with degree of kinship in cooperative coalitions of female red howler monkeys (Alouatta seniculus)

Female red howler monkeys were examined for three populations with different densities and growth rates, and reproductive success clearly increases with degree of gene correlation among females within cooperative coalitions, and coalitions that recruit more daughters produce more offspring.
Microsatellites in the bottlenose dolphin Tursiops truncatus
Five primer sets successfully amplified the target sequence and showed high levels of polymorphism in the bottlenose dolphin, and the utility of the primer sets for the amplification of microsatellite regions in four other cetacean species is tested.
Coastal bottlenose dolphins from southeastern Australia are Tursiops aduncus according to sequences of the mitochondrial DNA control region
The results strongly indicated that these two bottlenose dolphin populations from southeastern Australia belong to 2: aduncus, extending the range of the species to subtropical waters of the Western South Pacific Ocean.
Group Characteristics, Site Fidelity And Seasonal Abundance Of Bottlenosed Dolphins (Tursiops Aduncus) In Jervis Bay And Port Stephens, South-Eastern Australia
While mean group size of feeding dolphins did not vary between sites, travelling and socialising groups were significantly larger in JB, and the lack of dolphin matches between areas suggests that they represent distinct populations.
A tagging-observation program was conducted to study the behavioral ecology of Atlantic bottlenose dolphins near Sarasota, Florida, and found that social organization was characterized by small dynamic groups that appeared to be subunits of a larger socially interacting herd.
