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 Speckled dace (Rhinichthys osculus) is the most widespread minnow in western North America (Gilbert and Williams, 2002). It has diversified widely across its range—both morphologically and genetically—and as such might rightly be called a species complex. Our ongoing work aims to determine where boundaries between potentially undescribed species lie...

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...
