| Summary: | The interplay of natural selection and genetic drift, influenced by geographic isolation, mating systems and population size, determines patterns of genetic diversity within species. The sperm whale provides an interesting example of a long-lived species with few geographic barriers to dispersal. Worldwide mtDNA diversity is relatively low, but highly structured among geographic regions and social groups, attributed to female philopatry. However, it is unclear whether this female philopatry is due to geographic regions or social groups, or how this might vary on a worldwide scale. To answer these questions, we combined mtDNA information for 1091 previously published samples with 542 newly obtained DNA profiles (394-bp mtDNA, sex, 13 microsatellites) including the previously unsampled Indian Ocean, and social group information for 541 individuals. We found low mtDNA diversity (π = 0.430%) reflecting an expansion event <80 000 years bp, but strong differentiation by ocean, among regions within some oceans, ... : Sperm whale DNA profiles and sample informationTab delimited file (column names if different from column description are given in parentheses) of: sample name (Sample_ID); individual code (Individual_ID); latitude; longitude; date/time of sampling in format yyyy-mm-dd:T24:59 (Date_Time); region with abbreviations as follows: ALD: Aldabras, ATL: Atlantic crossing, AUS_SAUS: Australia, BAH: Bahamas, C_ATL: Central Atlantic, CNI: Canary Islands, COC: Cocos Island, E_MED: E.
