A bottleneck in population size of a species is often correlated with a sharp reduction in genetic variation. The northern elephant seal (Mirounga angustirostris) has undergone at least one extreme bottleneck, having rebounded from 20-100 individuals a century ago to over 175,000 individuals today. The relative lack of molecular-genetic variation in contemporary populations has been documented, but the extent of variation before the late 19th century remains unknown. We have determined the… 
Molecular Population Genetics of the Northern Elephant Seal Mirounga angustirostris
TLDR
It is demonstrated that genetic analysis can be useful for evaluating the population biology of the northern elephant seal, in spite of the bottleneck that removed most genetic variation from the species.
Genetic consequences of a severe population bottleneck in the Guadalupe fur seal (Arctocephalus townsendi).
Population bottlenecks may lead to diminished genetic variability and correlative effects on fitness. The Guadalupe fur seal was nearly exterminated by commercial sealers during the late 18th and
Genetic consequences of a demographic bottleneck in the Scandinavian arctic fox
TLDR
The results suggest that the genetic differentiation between North Russia and Scandinavia has doubled over the last 100 years, and the level of heterozygosity was significantly higher than expected from the simulations.
Spatial and temporal variation in genetic diversity of an endangered freshwater seal
TLDR
This study strongly suggests that enhancing gene flow and population growth is crucial for maintaining the remaining genetic diversity of the Saimaa ringed seal.
Consequences of a demographic bottleneck on genetic structure and variation in the Scandinavian brown bear
TLDR
The results have implications for the future management of the Scandinavian brown bear because they indicate a recent loss in genetic diversity and also that the current genetic structure may have been caused by historical ecological processes rather than recent anthropogenic persecution.
Impact of a population bottleneck on symmetry and genetic diversity in the northern elephant seal
TLDR
Comparison of archive samples collected prior to and following the northern elephant seal population bottleneck suggests a strong disruption in the pattern of allele frequencies following the bottleneck and measures of genetic diversity show a loss of variation consistent with expectations.
Low genetic variation support bottlenecks in Scandinavian red deer
TLDR
Hierarchical Bayesian coalescent analyses consistently yielded estimates of a large ancestral and a small current population size in all investigated European populations and suggested the onset of population decline to be between 5,000 and 10,000 years ago, which coincide well with postglacial colonisation.
Low Genetic Variation in the Heath Hen Prior to Extinction and Implications for the Conservation of Prairie-Chicken Populations
TLDR
This study examines the mitochondrial control region from museum specimens of the Heath Hen, which went extinct in 1932, and shows that 30 years prior to their extinction, Heath Hens had low levels of mitochondrial genetic variation when compared with contemporary populations of prairie-chickens.
Genetic diversity from pre-bottleneck to recovery in two sympatric pinniped species in the Northwest Atlantic
TLDR
Overall, the genetic data are consistent with the historical presence of large, genetically diverse populations of pinnipeds prior to human exploitation, and suggest that gray seals were more dramatically impacted by historical bottlenecks than harbor seals in the Northwest Atlantic.
Mitochondrial phylogeography of the Eurasian beaver Castor fiber L.
TLDR
The low level of sequence divergence of the entire cytochrome b gene among six individuals representing six subspecies suggests differentiation during the last glacial period and existence of multiple glacial refugia.

Elephant seal genetic variation and the use of simulation models to investigate historical population bottlenecks.
TLDR
DNA sequence diversity in two mtDNA regions was investigated and found low genetic variation in the northern elephant seal: there were only two control region haplotypes (sequence difference = 1%), which was consistent with an extreme founder event in the recent history of the northern species.
History and present status of the northern elephant seal population
I ABSTRACT. The northern elephant seal, Mirounga angustirostris, was presumed extinct by 1 89 2 owing primarily to commercial harvesting for their blubber oil that began in the early 1800s. A small,
Worldwide patterns of mitochondrial DNA differentiation in the harbor seal (Phoca vitulina).
TLDR
The results suggest that harbor seals are regionally philopatric, on the scale of several hundred kilometers, however, genetic discontinuities may exist, even between neighboring populations such as those on the Scottish and east English coasts or the east and west Baltic.

TLDR
It is suggested that the low levels of variability observed in endangered populations are more likely to result from a combination of publication biases, which tend to inflate the level of variability which is considered 'normal', and inbreeding effects, which may hasten loss of variability due to drift.
Molecular genetic diversity and evolution at the MHC DQB locus in four species of pinnipeds.
TLDR
A pattern of evolution of the immune response in pinnipeds similar to that in terrestrial mammal species is suggested, including the maintenance of polymorphisms by natural selection.
Elephant Seals: Genetic Variation and Near Extinction
TLDR
Blood samples from northern elephant seals, representing five breeding colonies in California and Mexico, were surveyed electrophoretically for protein variation reflecting underlying genetic differences, and no polymorphisms were found.
Molecular Evolutionary Genetics
TLDR
Recent developments of statistical methods in molecular phylogenetics are reviewed and it is shown that the mathematical foundations of these methods are not well established, but computer simulations and empirical data indicate that currently used methods produce reasonably good phylogenetic trees when a sufficiently large number of nucleotides or amino acids are used.
Palaeontology in a molecular world: the search for authentic ancient DNA.
TLDR
The survival of ancient DNA in specimens up to several thousands of years old is established, but the authenticity of these fossil DNA sequences is questionable on theoretical and empirical grounds, and the existence of authentic geologically ancient DNA remains to be proven.
New uses for old DNA.
TLDR
Researchers continue to find new ways to exploit preserved genetic information in studies of more recent remains, widening the utility of ancient DNA.

TLDR
A method for the reassembly of genes from their random DNA fragments, resulting in in vitro recombination is reported, and mixtures of synthetic oligonucleotides and PCR fragments can be mixed into a gene at defined positions based on homology.
