Figure S5. Candidate SNP allele frequencies by river mile location of collections of Pacific lamprey distributed throughout the range (blue) and within the Willamette River basin (orange). The candidate SNP Etr_464 represents the adaptive region on chromosome 1 that is associated with female maturity and the allele associated with small gonad size is plotted (left). The candidate SNP Etr_5713 represents the adaptive region on chromosome 2 that is associated with adult body size and the allele associated with large body size is plotted (right).

Figure S6. Temporal distributions of candidate SNP Etr_5317 using the adult Pacific lamprey migration at Willamette Falls. The timing of AA, AC, and CC genotypes at Etr_5317 for both a)2014 and b)2015 runs. The pies indicate the relative proportions of those genotypes for first and second halves of the run. The migration timing of the AA and CC genotypes are generally associated with large versus small body sizes among premature adults migrants. However, late stages of maturation causes body size shrinkage (Clemens et al . 2009) and so even genotypes associated with large and intermediate body size (i.e. genotypes AA and AC at Etr_5317) can exhibit relatively short body lengths in the lower 50% distribution of length when they mature. Genotypes at Etr_5317 did not show consistent trends in the first and second halves of the runs in 2014 and 2015, however when body size phenotypes and Etr_5317 genotypes were considered together there were consistent patterns (see Figure 5).
