MICROSATELLITE ANALYSIS OF POPULATION STRUCTURE IN THE SANTA ANA SPECKLED DACE (RHINICTHYS OSCULUS)
… was to characterize and identify polymorphic microsatellite markers for <em>R. osculus</em> in which twenty-three were identified through Illumina pair-end sequencing. Seven of these loci were then used to examine the patterns of genetic variation and population structure that occurred within …

Estimating Population Numbers of Black Bears (Ursus Americanus) in Eastern Kentucky Using Microsatellite Analysis
… 108 hair and scat samples were obtained. Eight microsatellite markers and one SRY marker were used to genotype and determine the sex of individual black bears. A minimum of thirty- nine different individuals (26 males and 13 females) were identified during the study period. Most of the …

Macrogeographic Genetic Structure in Acanthephyra curtirostris (Oplophoridae)
… <p>In this study, gene sequencing and microsatellite analysis were used to test the hypothesis that populations of the deep-sea, cosmopolitan, zooplanktic shrimp Acanthephyra curtirostris (Caridea: Oplophoridae) show genetic diversity within the northeastern Pacific. Tissue samples were …

Survivorship of ploidy-variable unisexual <i>ambystoma</i> aalamanders across developmental stages
… the frequency of ploidy levels (determined by microsatellite analysis) across four life stages within a single year: adults, early larvae, late larvae, and metamorphs. We found that, instead of an abrupt change due to individuals dying at or during metamorphosis, there was a gradual decline in …

The Genetic Consequences of Fragmentation and Small Population Size in Two Grassland Bird Species: The Greater Rhea and the Greater Prairie Chicken
"In addition, genetic analysis of four extant populations of the greater prairie chicken and museum specimens from a prebottlenecked population along with ecological data on population fitness allowed me to directly assess the effects of a demographic bottleneck on the genetic diversity and fitness …

Quantification of genetic variation on Island-breeding populations of Procellariiformes : an assessment of the impact of the longline fishing industry on seabirds
… study genetic variation was quantified using microsatellite analysis in order to investigate the effects of the longline fisheries on seabird populations. In addition, the feasibility of developing diagnostic markers for determining the provenance of birds forming part of the bycatch was also …

Empirical approaches to the conservation of Margaritifera Margaritifera
… intensification, as well as overexploitation. Analysis of recorded distribution data within the United Kingdom and Republic of Ireland showed that the Freshwater pearl mussel range contracted dramatically during the mid 20th century into core areas, however, not at an equal rate within each …

Evaluation of the establishment of predatory beetle, Laricobius nigrinus (Coleoptera: Derodontidae) in Virginia, and assessment of its impact on hemlock woolly adelgid (Hemiptera: Adelgidae) at release sites in the eastern U.S.
… a significant impact on the sistens generation. Microsatellite analysis of Laricobius larvae indicated that L. nigrinus was the primary species recovered at study sites.

Isolation and Characterization of Polymorphic Loci from the Caribbean Flamingo (Phoenicopterus ruber ruber): New Tools for Wildlife Management
… of choice is polymerase chain reaction-based microsatellite analysis. Seven new polymorphic loci were isolated from a microsatellite-enriched Caribbean flamingo genomic library and used to characterize survey populations of Caribbean and African greater flamingos. In addition, four of these …

Occurrence and genetic diversity of lemon sharks (Negaprion brevirostris) at a nursery ground at the Chandeleur Islands, Louisiana.
… of current literature, collection data, and microsatellite analysis it was possible to classify the Chandeleur Islands as an elasmobranch nursery ground under the definition presented by Huepel <em>et al. </em>(2007). Current literature and high densities of <em>N. brevirostris </em>suggests …

The drivers of variation in susceptibility to the amphibian-killing fungus, batrachochytrium dendrobatidis
… on the edge of their range in northwest Scotland.Microsatellites were used to characterise patterns of genetic variability across eleven populations. It was found that seawater serves to isolate demes, producing high levels of population differentiation, and that loss of genetic diversity …

Helminth, protozoan and viral infections of the European eel, Anguilla anguilla
… To explore the A.crassus population further, microsatellite analysis of 7 loci from 72 nematodes, sampled from 10different locations, was conducted. Although multiple alleles (between 12 and 38) existed at allanalysed loci, genetic differentiation of A. crassus was low (average FST = 0.037). …

Female preferences, paternity and fitness: A combined morphometric/molecular genetic study on Poecilia latipinna and Poecilia formosa
… a non-preferred male, paternity was assigned via microsatellite analysis. Poecilia formosa females (N = 34) were mated with either a preferred or a non-preferred male. I found evidence that female preferences in both species did not depend on male size (a measure for male quality). But in P. …

The thermal macrophysiology of core and marginal populations of the aphid Myzus persicae in Europe
… heat tolerance. Clonal type, as identified by microsatellite analysis, did show a relationship with thermal tolerance, suggesting that clonal types could respond independently to climate change, affecting relative proportions of clones within populations.

Development of intermonoploid somatic hybrids of potato and their molecular analysis based on polymorphism for retroelement Tst1
… determined by flow-cytometry and SH confirmed by microsatellite analysis. Field evaluations over three years revealed that intermonoploid SH were inferior to cultivars. Dihaploids derived by anther culture of a tetraploid intermonoploid SH were reduced in vigor with an increase in homozygosity, …

Genetic variation within the Icelandic goat breed: assessment using population data and DNA analysis
… on the base of both pedigree information and DNA analysis. The estimate is based on three approaches. Firstly, pedigree information is used to calculate the rate of inbreeding, pedigree completeness, generation interval, effective population size, highest contributing ancestors and relationship …

Genetic variation within the Icelandic cattle breed: assessment using microsatellites and analysis of single nucleotide polymorphisms in the Leptin and DGAT1 genes
… the samples were genotyped with a set of eleven microsatellite markers and various diversity indices calculated. Second, parts of the Leptin and DGAT1 genes were sequenced in order to search for single nucleotide polymorphisms (SNPs), (several in the Leptin gene and a well known dinucleotide …

Population ecology and conservation genetics of the smooth snake (Coronella austriaca) in a fragmented heath landscape
… occupied sites.<br/>Eight previously described microsatellite markers were used to complete the first assessments of the genetic population structure of C. austriaca at two spatial scales. Initial fine-scale analysis of structuring based on 11 sampling localities within a heathland/coniferous …

An Investigation for Genetic Susceptibility to Type 1 Diabetes Mellitus and its Microvascular Complications
… study, polymerase chain reaction (PCR)-based microsatellite analysis and restriction fragment length polymorphism (RFLP) analysis were used to genotype the genes coding for NFκB, HSP70-A2, sorbitol dehydrogenase (SORD) and protein kinase C- β(PKC-β). The A10 allele of the NFκB gene and H3 and …
