Data from: Genomic variation underlying complex life history traits revealed by genome sequencing in Chinook salmon

Shawn R. Narum, Alex Di Genova, Steven J. Micheletti, Alejandro Mass & Alejandro Maass
A broad portfolio of phenotypic diversity in natural organisms can buffer against exploitation and increase species persistence in disturbed ecosystems. The study of genomic variation that accounts for ecological and evolutionary adaptation can represent a powerful approach to extend understanding of phenotypic variation in nature. Here we present a chromosome-level reference genome assembly for Chinook salmon (Oncorhynchus tshawytscha; 2.36 Gb) that enabled association mapping of life history variation and phenotypic traits for this species. Whole...

Data from: Physiological and genomic signatures of evolutionary thermal adaptation in redband trout from extreme climates

Zhongqi Chen, Anthony P. Farrell, Amanda Matala, Nicholas Hoffman & Shawn R. Narum
Temperature is a master environmental factor that limits the geographical distribution of species, especially in ectotherms. To address challenges in biodiversity conservation under ongoing climate change, it is essential to characterize relevant functional limitations and adaptive genomic content at population and species levels. Here, we present evidence for adaptive divergence in cardiac function and genomic regions in redband trout (Oncorhynchus mykiss gairdneri) populations from desert and montane streams. Cardiac phenotypes of individual fish were measured...

Data from: Utility of pooled sequencing for association mapping in non-model organisms

Steven J. Micheletti & Shawn R. Narum
High density genome-wide sequencing increases the likelihood of discovering genes of major effect and genomic structural variation in organisms. While there is an increasing availability of reference genomes across broad taxa, the greatest limitation to whole-genome sequencing of multiple individuals continues to be the costs associated with sequencing. To alleviate excessive costs, pooling multiple individuals with similar phenotypes and sequencing the homogenized DNA (Pool-Seq) can achieve high genome coverage, but at the loss of individual...

Data from: Long-term evaluation of fitness and demographic effects of a Chinook salmon supplementation program

Ilana Janowitz-Koch, Craig Rabe, Ryan Kinzer, Doug Nelson, Maureen A. Hess & Shawn R. Narum
While the goal of supplementation programs is to provide positive, population-level effects for species of conservation concern, these programs can also present an inherent fitness risk when captive-born individuals are fully integrated into the natural population. In order to evaluate the long-term effects of a supplementation program and estimate the demographic and phenotypic factors influencing the fitness of a threatened population of Chinook salmon (Oncorhynchus tshawytscha), we genotyped tissue samples spanning a 19-year period (1998-2016)...
