Correction: Linking Genetic Variation in Adaptive Plant Traits to Climate in Tetraploid and Octoploid Basin Wildrye [Leymus cinereus (Scribn. & Merr.) A. Love] in the Western U.S.

[This corrects the article DOI: 10.1371/journal.pone.0148982.].

There is an error in Table 3. In the column for leaf ratio, the octoploid and tetraploid values were reversed, so when significant, the tetraploids rather than the octoploids had the greater leaf ratio values. The written descriptions of the results and discussion are not affected. Please see the corrected Table 3 here.

Table 3

Mean comparisons between wild octoploid (n = 57) and tetraploid (n = 52) basin wildrye among years and common gardens sites at Central Ferry (CF) and Pullman (PU), WA.
