Correlation between USV emission and the latency to the first litter (LFL). Each symbol represents one breeding pair consisting of either unrelated (blue circles) or related (red triangles) individuals. During the introduction phase (a) the grand mean frequency of USVs (kHz) and (b) the vocal repertoire (number of syllable types emitted during 10 min) were correlated with LFL in related pairs. During the interaction phase (c) the mean length of USVs (ms) and (d) the number of simple syllable types (total number of simple syllables emitted during 10 min) were correlated with LFL in unrelated pairs
