 expanded this definition to include groups that travel 

 in unison with their pod but rarely mix with other 



groups within the pod. This latter situation occurred 

 only for AB pod, which was divided into three 

 subpods. By direct observation and examination of

Top: dendrogram illu.strating intrapod groups and relationships among individuals with CAI values calculated at the population 

 level. (Relationships among intrapod groups shown in Fig. 2.) Middle: matrix showing CAI values between pairs of individuals 

 calculated at the pod level for AN20 pod. Numbers at the base of each column in the matrix are the number of valid photo 

 sequences in which that individual appears. Bottom: inferred genealogical trees.
