The human molecular clock and mutation process : a characterization using microsatellite DNA
… on studying human evolution through the use of microsatellites, which are simple repetitive sections of DNA of typically 1-6bp motifs (e.g. CACACACACA) that are highly polymorphic and highly mutable. The first aim is to establish that microsatellites are useful as reliable molecular clocks, such …

Characterisation of the population genetics of farm-bred Haliotis midae using microsatellite DNA markers
… was investigated in order to determine whether microsatellite DNA analysis could be used to separate farmed abalone into phenotypically different groups with respect to growth rate. Microsatellites display high levels of variability and this makes them suitable for a wide variety of applications …

Population structure of lake trout (Salvelinus namaycush) In Atlin Lake, British Columbia and contributions to local fisheries: a microsatellite DNA-based assessment
… other western lake trout populations at eight microsatellite DNA loci and for body morphology to determine: (i) the level of genetic variation present, (ii) the level of substructure that occurs in Atlin Lake, and (iii) whether there was a relationship between the genetic and morphological …

Evaluation of the Genetic Management of the Endangered Mississippi Sandhill Crane (Grus canadensis pulla)
… managed captive breeding and release program. Microsatellite DNA data provided information on shared founder genotypes, allowing for refined analysis of genetic variation in the population, and informed breeding recommendations. The genetic variation observed in the Mississippi sandhill crane …

The development of the single-strand conformation polymorphism (SSCP) technique to assess sequence level variation within the major histocompatibility complex (MHC) DRB1 gene in four South African buffalo (Syncerus caffer) populations
… in a study on the same populations using microsatellite DNA, (iv) the statistical comparisons were used to assess the appropriateness of SSCP data for population genetic analysis. Levels of heterozygosity, allelic diversity and population differentiation were quantified using MHC DRB1 …

Genetic diversity in Neospora caninum
… approaches such as sequencing of ribosomal DNA. Mini- and microsatellite DNA markers have recently been reported to represent a valuable tool to study genetic diversity within this parasite. This is the topic of this thesis. In the present study, mini- and microsatellite DNA markers were …

The Population Genetics Of The Wood Frog, Rana Sylvatica, Across Its Geographic Range
… locations of glacial refugia for this species. DNA microsatellites were used as the genetic marker. This study found significant genetic differentiation across the geographic range of Rana sylvatica that increased with geographic distance. In addition three likely glacial refugia, Alaska, New …

Genetic Variation Among Geographically Disparate Yellow Perch Broodstock Populations
… selection, genetic variation revealed by microsatellite DNA was evaluated in yellow perch, Perca flavescens, from four wild North American populations collected in 2003-2004 (Maine, ME; New York, NY; North Carolina, NC; and Pennsylvania, PA), and two captive populations (Michigan, MI; …

Determining parentage and the effects of relatedness on play partner preference in Belding's ground squirrels
… litters. I evaluated paternity using microsatellite DNA analysis, which is more accurate than examining blood allozymes. My results indicate that multiple paternity in <em>U. beldingi</em> is more extensive than previously shown, occurring in about 90% of litters with more than one …

Spatial and temporal population genetics at deep-sea hydrothermal vents along the East Pacific Rise and Galápagos Rift
… disjunct habitats, a suite of 12 highly variable microsatellite DNA markers were developed for this species. Eight of these loci were used to assess the regional and within-ridge genetic structure of recent colonists and resident adults collected from nine sites in the eastern Pacific Ocean over …

Population genetics of wood frogs (Lithobates sylvaticus) in a forested ridge-top wetland ecosystem
… this. Genetic data were analyzed for nine microsatellite DNA loci from twenty-five wood frog egg clutches at each of five randomly selected natural wetlands. Overall, genetic variation was measured by calculating observed heterozygosity (0.250-0.960), expected heterozygosity (0.270-0.913), …

Genetic Marker-Assisted Management of Virginia Sport Fishes
… exhibit low genetic variation. Screening 12 microsatellite DNA markers across the range to define population genetic structure, I found that anadromous populations in the Southeast and the Chesapeake Bay were differentiated from landlocked populations in the Roanoke River basin, with an …

Detectability, movement, and population structure of the endangered Candy Darter in Virginia
… is greater than previously described. Using microsatellite DNA markers, I describe population genetic structure and estimate effective population sizes of the four extant populations of Candy Darter in Virginia and provide insight into which populations may be successful as sources for …

Conservation and management of the Allegheny woodrat in the central Appalachians
… for this species.;I developed 11 polymorphic microsatellite DNA markers and examined Allegheny woodrat genetic variation at two spatial scales, geographically distinct regional populations and subpopulations within regional populations. The markers detected significant genetic variation and …

Salamander Mating Behaviors and Their Consequences for Individuals and Populations
… summarizes the characteristics of several novel microsatellite DNA loci as well as cross-amplified loci for marbled salamanders and mole salamanders that may be used for future studies. In the second chapter, I report estimates of sire number for 13 marbled salamander clutches based on …

Population Structure of Lake Whitefish (Coregonus Clupeaformis) on Multiple Spatial Scales: Transitioning to a Genomics Approach
… undertaken to inform the recent transition from microsatellite DNA markers to single nucleotide polymorphisms (SNPs) in the field of molecular ecology, and to explore the population structure of important fish species. Microsatellite markers were the gold standard for two decades and were used to …

Genetic Characterization of Intermixed Walleye Stocks in Claytor Lake and the Upper New River, Virginia
… areas, such as Fosters Falls. Using allozymes, microsatellite DNA, and mitochondrial DNA marker techniques to examine population structure of walleye, I determined that the walleye within Claytor Lake are a panmictic population. This is the result of years of stocking walleye from different …

The study of molecular variation in Atlantic salmon (Salmo salar L.) and brown trout (Salmo trutta L.)
Polymorphic microsatellite DNA loci were used here in three studies, one on Salmo salar and two on S. trutta. In the case of S. salar, the survival of native fish and non-natives from a nearby catchment, and their hybrids, were compared in a freshwater common garden experiment and subsequently in …

Genetic diversity and hybridisation estimates of Arctocephalus tropicalis and A. gazella from Marion Island
… region I (HVRI) of the mitochondrial DNA (mtDNA) control region, and five microsatellite loci were used to assess genetic variability and the extent of hybridization between the two fur seals (Arctocephalus tropicalis and A. gazella), that occur on Sub-Antarctic Marion Island. Both …
