What influences the worldwide genetic structure of sperm whales (Physeter macrocephalus)?

Creator:

Alexander, Alana, Steel, Debbie, Hoekzema, Kendra, Mesnick, Sarah L., Engelhaupt, Daniel, Kerr, Iain, Payne, Roger, and Baker, C. Scott

Abstract:

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...

The influence of social structure and molecular evolution on genetic diversity in the sperm whale (Physeter macrocephalus)

Creator:

Alexander, Alana

Abstract:

The sperm whale (Physeter macrocephalus) shows some of the most derived characteristics of any mammal: a large body size, large brain, complex social organization and a capacity for deep foraging dives that few other marine mammals can match. Despite a history of exploitation that removed hundreds of thousands of individuals,...

Low Diversity in theMitogenome of Sperm Whales Revealed by Next-Generation Sequencing

Creator:

Alexander, Alana, Steel, Debbie, Slikas, Beth, Hoekzema, Kendra, Carraher, Colm, Parks, Matthew, Cronn, Richard, and Baker, C. Scott

Abstract:

Large population sizes and global distributions generally associate with high mitochondrial DNA control region (CR) diversity. The sperm whale (Physeter macrocephalus) is an exception, showing low CR diversity relative to other cetaceans; however, diversity levels throughout the remainder of the sperm whale mitogenome are unknown. We sequenced 20 mitogenomes from...
