Data from: Kinship influences sperm whale social organization within, but generally not among, social units ...
Sperm whales have a multi-level social structure based upon long-term, cooperative social units. What role kinship plays in structuring this society is poorly understood. We combined extensive association data (518 days, during 2005-2016) and genetic data (18 microsatellites and 346bp mtDNA control...

| Summary: | Sperm whales have a multi-level social structure based upon long-term, cooperative social units. What role kinship plays in structuring this society is poorly understood. We combined extensive association data (518 days, during 2005-2016) and genetic data (18 microsatellites and 346bp mtDNA control region sequences) for 65 individuals from 12 social units from the Eastern Caribbean to examine patterns of kinship and social behaviour. Social units were clearly matrilineally-based, evidenced by greater relatedness within social units (mean r=0.14) than between them (mean r=0.00) and uniform mtDNA haplotypes within social units. Additionally, most individuals (82.5%) had a first-degree relative in their social unit, while we found no first-degree relatives between social units. Generally and within social units, individuals associated more with their closer relatives(matrix correlations: 0.18-0.25). However, excepting a highly-related pair of social units that merged over the study period, associations between ... : GeneticData_byIndIndividual genetic data and unit assignment: Unit assignment, sex, mtDNA haplotype, and microsatellite genotypes for all unique genetic individuals.UnitAssociationsUnit-level association matrices: Association matrices for sperm whale social units, using half-weight association indices, calculated for four different combinations of association measures and sampling intervals. ... |
