Figure 5 



Top: dendrogram illustrating intrapod groups and relationships among individuals with CAI values calculated 

 at the population level. (Relationships among intrapod groups shown in Fig. 2.1 Middle: matrix showing CAI 

 values between pairs of individuals calculated at the pod level for ADS 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. 



and AN48; ANl 1 and calves AN47 and AN49). These 

 females became most closely bonded to their own 

 calves rather than to their mothers. One juvenile 

 ^oiale, AN19, had a stronger bond with apparent ju- 

 venile sibling AN18 (CAI=16) than with his appar- 

 ent mother, reproductive female AN17 (CAI=4). The 



juvenile AB18 had a stronger bond (CAI=58) with a 

 young calf AB41, in his intrapod group than with 

 his apparent mother, reproductive female AB7 

 lCAI=22). However, in the cases of all five of these 

 whales, the strongest bond with an adult female re- 

 mained with their apparent mothers.
