Abstract: Social relationships in female mammals are usually determined by
an interplay among genetic, endogenous, social and ecological factors that
ultimately affect their lifetime reproductive success. However, few studies
have attempted to control for, and integrate these factors, hampering our
understanding of drivers underlying female sociality. Here, we used
generalized affiliation indices, combined with social networks,
reproductive condition, and genetic data to investigate drivers of
associations in female southern Australian bottlenose dolphins. Our
analysis is based on photo-identification and genetic data collected
through systematic boat surveys over a two-year study period. Female
dolphins formed preferred associations and social clusters which ranged
from overlapping to discrete home ranges. Furthermore, matrilineal kinship
and biparental relatedness, as well as reproductive condition, correlated
with the strength of female affiliations. In addition, relatedness for both
genetic markers was also higher within than between social clusters. The
predictability of resources in their embayment environment, and the
availability of same-sex relatives in the population, may have favoured the
formation of social bonds between genetically related females and those in
similar reproductive condition. This study highlights the importance of
genetic, endogenous, social and ecological factors in determining female
sociality in coastal dolphins.
