  1. ESM 3: Graphical representation (a) and statistical results (b) of the Discriminant Functional Analysis used to test the reliability of the call-to-caller assignment in male small-clawed otters. • Social partner discrimination based on sounds and scents in Asian small-clawed otters(Aonyxcinereus), Naturwissenschaften, Lemasson, Mikus, Blois-Heulin, Lodé; Animal and Human Ethology lab, Rennes 1 University (France), alban.lemasson@univ-rennes1.fr (a) (b) Males: M3 M4 M2 M1 M5 Discriminant function 2 Discriminant function 1 The Discriminant Functional Analysis was done used 100 calls (20 per male) as a training sample and 100 other calls as a test sample. Definition of the acoustic variables correlated with functions 1 and 2: duration of the call (Dt), number of harmonics (H), fundamental frequency at the beginning (F0beg), end (F0end) and top (F0max) of the call.
