Table 3. Social accommodation over time.

The effect of sex, exposure time and the interaction thereof on vocal distance (ln-transformed Euclidean distance) between the vocalisations of four translocated MA individuals and the call type specific average of the new population (“Baseline ZH colony”) for each call type. Parameter estimates, standard errors, and statistical significance are obtained from a linear mixed effects model. Significant (highest-order) effects are indicated with p-values in bold, trends in italics.
