Figure 1From: Vocal communication in a complex multi-level society: constrained acoustic structure and flexible call usage in Guinea baboonsResults of a two-step cluster analysis. Respective Silhouette values (Sc) of each clustering are shown in the graph. The black dot indicates the solution chosen for the discriminant function analysis (DFA). This six call-cluster solution was the most appropriate one, since it yields a high cluster validity and corresponded to most of the audibly distinct call types.Back to article page
