(A) Vocalization minimum frequency as a function of species body mass for terrestrial (n = 105), semiaquatic (n = 23), and aquatic (n = 42) environments on a log scale. The dotted line represents the phylogenetic generalized least squares (PGLS) regression line for terrestrial mammals log(Y) = –0.41log(X)–0.21 (CI –0.50, –0.32) the dash‐dot line represents semiaquatic mammals log(Y) = –0.41log(X) + 0.06 (CI –0.50, –0.32) and the solid line for aquatic mammals log(Y) = –0.41log(X) + 0.93 (CI –0.50, –0.32).

(B) Vocalization maximum frequency as a function of species body mass for terrestrial (n = 125), semiaquatic (n = 23), and aquatic (n = 41) environments on a log scale. Terrestrial mammals log(Y) = –0.38log(X) + 0.98 (CI –0.34, –0.06), semiaquatic mammals log(Y) = –0.18log(X) + 1.13 (CI –0.28, 0.45), and aquatic mammals log(Y) = –0.18log(X) + 1.63 (CI –0.31, –0.06).
