Assessing substitution patterns, rates and homoplasy at HVRI of Steller sea lions, Eumetopias jubatus.

14 Jul 2009 Despite the widely recognized incidence of homoplasy characterizing this region, the hypervariable region I (HVRI) of the mitochondrial control region is one of the most frequently used genetic markers for population genetic and phylogeographic ... Read more...

Contrasting patterns of genetic diversity at three different genetic markers in a marine mammal metapopulation.

2 Jun 2009 Many studies use genetic markers to explore population structure and variability within species. However, only a minority use more than one type of marker and, despite increasing evidence of a link between heterozygosity and individual fitness, few ... Read more...

The monophyletic origin of sea lions and fur seals (Carnivora; Otariidae) in the Southern Hemisphere.

25 Feb 2009 The pinniped family Otariidae (sea lions and fur seals) is composed of 7 extant genera with 14 species. They are mainly distributed in the Southern Hemisphere, but the fossil record is only known from the Northern Hemisphere until Pliocene. To ... Read more...
