Data from: Genotyping SNPs and inferring ploidy by amplicon sequencing for polyploid, ploidy-variable organisms

Thomas Delomas, Stuart Willis, Blaine Parker, Donella Miller, Paul Anders, Andrea Schreier & Shawn Narum
Whole genome duplication is hypothesized to have played a critical role in the evolution of several major organism groups, including vertebrates, and while many lineages have rediploidized, some retain polyploid genomes. Additionally, variation in ploidy can occur naturally or be artificially induced within select plant and animal species. Modern genetic techniques have not been widely applied to polyploid or ploidy-variable species, in part due to the difficulty of obtaining genotype data from polyploids. In this...

Data from: Genomic region associated with run-timing has similar haplotypes and phenotypic effects across three lineages of Chinook salmon

Stuart Willis
Conserving life history variation is a stated goal of many management programs, but the most effective means by which to accomplish this are often far from clear. Early, premature migrating and late, mature migrating forms of Chinook salmon face unequal pressure from natural and anthropogenic forces. These forces may result in the diminishment of migration variation in some stocks because migration timing is known to be highly heritable. Genomic regions of chromosome 28 are known...

Chinook salmon environmental data and allele frequency matrix

Yara Alshwairikh, Rebekah Horn, Travis Seaborn, Shawn Narum, Lisette Waits, William Swain, Steve Stephens-Cardenas, Jenny Olsson & Shayla Kroeze
Many species that undergo long breeding migrations, such as anadromous fishes, face highly heterogeneous environments along their migration corridors and at their spawning sites. These environmental challenges encountered at different life stages may act as strong selective pressures and drive local adaptation. However, the relative influence of environmental conditions along the migration corridor compared to the conditions at spawning sites on driving selection is still unknown. In this study, we performed genome-environment associations (GEA) to...

Heterogeneous genetic basis of age at maturity in salmonid fishes

Charles Waters, Anthony Clemento, Tutku Aykanat, John Garza, Kerry-Ann Naish, Shawn Narum & Craig Primmer
Understanding the genetic basis of repeated evolution of the same phenotype across taxa is a fundamental aim in evolutionary biology and has applications to conservation and management. However, the extent to which interspecific life-history trait polymorphisms share evolutionary pathways remains under-explored. We address this gap by studying the genetic basis of a key life-history trait, age at maturity, in four species of Pacific salmon (genus Oncorhynchus) that exhibit intra- and interspecific variation in this trait...
