Genetic Stock Structure, Relative Productivity and Migration (Gene Flow) of White Sturgeon Among Bonneville, The Dalles, John Day and McNary Reservoirs in the Lower Mid-Columbia River Region

This report presents the results of genetic monitoring of white sturgeon (Acipenser transmontanus) in the second of a ten year implementation period for the project. These results will be used to address long-term objectives for monitoring and conservation of populations among four upstream...

Genetic Variation and Structure of Chinook Salmon Life History Types in the Snake River

We evaluated 25 inland populations of Chinook salmon (Oncorhynchus tshawytscha) in the Snake River with 13 microsatellite loci to test for contemporary genetic differentiation at three scales: between life history types, among regions within life history types, and among populations within...

Genome-wide Association Reveals Genetic Basis for the Propensity to Migrate in Wild Populations of Rainbow and Steelhead Trout

Little is known of the genetic basis of migration despite the ecological benefits ...

Genomic Islands of Divergence Infer a Phenotypic Landscape in Pacific Lamprey

High rates of dispersal can breakdown coadapted gene complexes. However, concentrated genomic architecture (i.e., genomic islands of divergence) can suppress recombination to allow evolution of local adaptations despite high gene flow. Pacific lamprey (Entosphenus tridentatus) is a highly...

Genomic Patterns of Diversity and Divergence of Two Introduced Salmonid Species in Patagonia, South America

Invasive species have become widespread in aquatic environments throughout the world, yet there are few studies that have examined genomic variation of multiple introduced species in newly colonized environments. In this study, we contrast genomic variation in two salmonid species (anadromous...

Genomic Signatures Among Oncorhynchus nerka Ecotypes to Inform Conservation and Management of Endangered Sockeye Salmon

Conservation of life history variation is an important consideration for many species with trade‐offs in migratory characteristics. Many salmonid species exhibit both resident and migratory strategies that capitalize on benefits in freshwater and marine environments. In this study, we investigated...

Genomics in Conservation: Case Studies and Bridging the Gap Between Data and Application

We agree with Shafer et al. [1] that there is a need for well-documented case studies of the application of genomics in conservation and management as well as increased communication between academics and natural resource managers. However, we challenge Shafer et al.’s [1]...

Genotyping-by-sequencing in Ecological and Conservation Genomics

The fields of ecological and conservation genetics have developed greatly in recent decades through the use of molecular markers to investigate organisms in their natural habitat and to evaluate the effect of anthropogenic disturbances. However, many of these studies have been limited to narrow...

Genotyping-in-thousands by Sequencing (GT-seq): A Cost Effective SNP Genotyping Method Based on Custom Amplicon Sequencing

Genotyping-in-Thousands by sequencing (GT-seq) is a method that uses next-generation sequencing of multiplexed PCR products to generate genotypes from relatively small panels (50–500) of targeted single-nucleotide polymorphisms (SNPs) for thousands of individuals in a single Illumina HiSeq lane....

Genotyping-in-Thousands by Sequencing (GT-seq): A Low Cost, High-throughput, Targeted SNP Genotyping Method

GT-seq is a genotyping method which leverages large read numbers from Illumina sequencers to genotype hundreds of single nucleotide polymorphisms within pools of multiplex PCR amplicons generated from thousands of individual samples. This method produces genotypes that are 99.9% concordant to those...
