The authors acknowledge the contributions of Nate Campbell and Andrew Matala in initial modification to the GT-seq pipeline to accommodate tetraploid data, analysis of the RAD data to identify variant sites, curation of the white sturgeon ascertainment samples and data, and filtering of candidate markers. Andrea Schreier provided insightful discussion on ploidy patterns in white sturgeon. Lori Maxwell and Stephanie Harmon assisted in the lab with preparation of samples and sequencing. The white sturgeon project was supported by Bonneville Power Administration (Grant no. 2008-907-00).
