CHARACTERIZATION OF MICROSATELLITE LOCI AND PILOT POPULATION GENETIC ANALYSIS IN HICKORY SHAD, ALOSA MEDIOCRIS
… analysis of this species, employed 12 neutral microsatellite loci to estimate genetic diversity and population structure in tributaries of lower Chesapeake Bay, Virginia including James River and its tributaries (Appomattox and Chickahominy Rivers), Rappahannock River, and Pamunkey River. …

Identification and isolation of microsatellite loci from the Trematode Echinostoma Trivolvis for use in interspecific and intraspecific variation studies
… a significant impact on amphibian populations. Microsatellite markers were to be identified and isolated because of their highly variable nature and reported ease of use with PCR. Parasite DNA was extracted from planorbid snails from several locations within California including: Point Reyes …

Development and Characterization of Microsatellite Markers for the Grain Amaranths (Amaranthus spp. L.)
… a set of highly informative, reproducible microsatellite markers for the grain amaranths. A total of 1457 clones were sequenced from three genomic libraries enriched for the microsatellite motifs AAC, AAT and AC. Of these, 353 (24%) contained unique microsatellites. An additional 29 …

Microsatellite-based genetic profiling for the management of wild and captive flamingo populations.
… lack of genetic data for flamingo populations. Microsatellites are loci composed of 2-6 base pair tandem repeats, scattered throughout higher eukaryotic genomes, often exhibiting high levels of polymorphism and heterozygosity. These loci are thus important genetic markers for identity, parentage …

A Systematic Review of the Viola palmata Species Complex in the Gulf Coastal Plain and Southern Appalachians
… and analyzed for phylogenetic analysis; four microsatellite loci were amplified, run on a gel for detection and sizing of alleles, and analyzed for population and/or geographic patterns. At each population, soil characteristics including soil texture, pH, percent organic matter, and …

Comparative Phylogeography of Eastern Chipmunks and White -Footed Mice: Population Histories Since the Last Glacial Maximum
Finally, analyses of variation at 6 microsatellite loci among 210 P. leucopus from three sites each around three of the largest cities in Illinois recovered reduced levels of gene flow among sites separated by urban development compared to sites separated by deciduous forest habitat. Mitochondrial …

A Holistic Approach to Taxonomic Evaluation of Two Closely Related Endangered Freshwater Mussel Species, the Oyster Mussel (Epioblasma capsaeformis) and Tan Riffleshell (Epioblasma florentina walkeri) (Bivalvia: Unionidae)
Primers for 10 polymorphic DNA microsatellite loci were developed and characterized for the endangered oyster mussel Epioblasma capsaeformis from the Clinch River, TN. Microsatellite loci also were amplified for individuals collected from the following additional populations or species: (1) E. …

Fine-scale genetic structure and parentage in Urocitellus beldingi
… and demographically for several decades. Microsatellites were developed for this species and conditions for polymerase chain reaction (PCR) were defined. Nine microsatellite loci amplified adequately and were in Hardy-Weinberg equilibrium, displaying an average heterozygosity of 0.67±0.19. …

An investigation of genetic heterogeneity in a biological sentinel species (Lumbricus rubellus)
… in a second study featuring cross-amplifying microsatellite loci. Both the sequencing and fragment analysis of these microsatellite loci strongly supported the existence of a high degree of reproductive isolation between the two lineages.<br/><br/>Finally microsatellite markers were applied to …

Supplementing the studbook. Using genetic analysis to complement a captive breeding programme of an endangered primate, Hylobates moloch.
… DNA hypervariable region-I (mtDNA HV-I), 15 microsatellite loci and the second exon of the major histocompatibility complex (MHC) DRB region, were carried out to ascertain genetic variability levels, levels of inbreeding, signs of selection and confirm the pedigree. Captive born individuals …

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 …

Misura della connettività e della dispersione dell’aragosta rossa Palinurus elephas (Fabricius, 1787) in Sardegna con l’uso di marcatori genetici STRs e mitocondriali
… two different molecular markers: 10 different microsatellite loci, of nuclear origin, and a portion of the mitochondrial control region. The two types of markers have substantial differences in terms of measuring the spatial and temporal variability, thus can be considered complementary in the …

Toward genetic marker-assisted improvement of aquaculture stocks
… for applying genomic mapping, quantitative trait loci (QTL) detection and marker-assisted selection (MAS) to genetic improvement of aquaculture species. Genes affecting aquaculture performance, or quantitative trait loci (QTLs}, can be mapped in relation to naturally-occuring genetic markers. …

Molecular Evidence Suggests Multiple Evolutionary Origins of Sociality in the Polyphenic Spider <em>Anelosimus studiosus</em> (Araneae: Theridiidae).
… thus leading to multiple origins of evolution. Microsatellite loci were used to determine genetic structure of the population and to estimate the origins of social behavior. All loci showed lower observed than expected heterozygosities and all populations show indications of high levels of …

Temporal changes in unisexual and sexual Ambystoma salamander populations in southeast Michigan
… using epidermal cell nuclei measurements and microsatellite loci. I found that population composition has shifted away from the more northern-distributed <em>A. laterale</em> and toward populations dominated by unisexuals in five out of six ponds. There was a significant relationship between …

Population genetics and evolutionary history of some deep-sea demersal fishes from the Azores - North Atlantic
MtDNA sequences and microsatellite loci were used as independent molecular markers to reveal the genetic population structure in three deep-sea demersal fish species from the North Atlantic. In the Azores archipelago, the demersal fishery is the second most important after tuna and Helicolenus …

Effects of Culverts on Brook Trout Genetic Diversity
… were genetically analyzed using a suite of 13 microsatellite loci above 7 culverts with varying levels of passability classified through a physical protocol. While most sites were not found to have losses in genetic diversity, populations above culverts with a high outlet drop were found to …

Influence Of Landscape On Gene Differentiation In The American Pika (Ochotona princeps) Within The Interstate 90 Snoqualmie Pass Corridor
… from 85 individuals and genotyped at six microsatellite loci to determine genetic differentiation among each pair of patches. A variety of models estimating the influence of landscape factors on gene flow were then used to find “resistance scores” between each pair of patches using the …

Genetic diversity and population structure of Vaccinium vitis-idaea
… across 15 populations, assayed at 18 nuclear microsatellite loci to reveal the sexual and asexual reproductive strategies of this species. Five of the fifteen populations were found to consist of only two clones each, while other populations maintained a higher number of genetically unique …
