Table 1 depicts the demographics of each social group (A-D) during the study period 2012-2014 (top) as well as the historical components during original group formation (bottom).

^*Data from group D includes only years 2013 and 2014 due to a temporary group split in 2012 for management purposes.

^**A subset of animals was removed from group C in 2002 and the number of matrilines was reduced from 34 to 14.
