Fig 3. Composition of the vocal repertoire produced by male and estrous female golden hamsters after interacting with an opposite sex individual.

(A) Proportion of USV produced based on structural complexity (GLM, Complexity*Sex: F 5,72 = 4.10, P = 0.0205). (B) Proportion of simple call types produced in each of the 8 major categories (FT = Flats, 1-FJ = one frequency jump, multi-FJ = two or more frequency jumps) (GLM, Call type*Sex: F 15,192 = 1.54, P = 0.156). (C) Proportion of simple call types produced merged into 5 major categories. The category Wavy merged the waves, humps and chevrons and the category Frequency Jumps (F. Jumps) merged 1-FJ and multi-FJ types from previous categorization based on 8 categories (GLM, Call type*Sex: F 9,120 = 2.04, P = 0.0925). (D) Proportion of USV produced based on different levels of deterministic chaos (L = lineal, DC1 = deterministic chaos 1, DC2 = deterministic chaos 2, DC3 = deterministic chaos 3) (GLM, DC*Sex: F 7,96 = 4.11, P = 0.0087). (E) Proportion of USV produced based on the presence or absence of frequency jumps (FJ), (GLM, Sex*FJ: F 3,48 = 3.62, P = 0.0007). *P ≤ 0.05, **P ≤ 0.01.
