Biological Sciences Correction for “Functional consequences of convergently evolved microscopic skin features on snake locomotion,” by Jennifer M. Rieser, Tai-De Li, Jessica L. Tingle, Daniel I. Goldman, and Joseph R. Mendelson III, which published February 5, 2021; 10.1073/pnas.2018264118 (Proc. Natl. Acad. Sci. U.S.A. 118, e2018264118).
The authors note: “The denominator in Eq. 6 is mistyped in the manuscript. We note that all results presented in the original manuscript are not affected as the correct equation was used for all calculations. Eq. 6 should read: S(δ(r)) = 1/(1+exp[a(δ(r)+b)]).”
The online version has been corrected.
