Passage II
Meerkats (Suricata suricatta) are mammals that typically live in groups of 2 to 30 individuals. Some group members called helpers, help parents care for their pups. Figure 1 shows how the percent contribution to babysitting and to pupfeeding by helpers varied with the age of the helpers, as categorized in Table 1.
A helper's food intake, as measured by daily weight gain (average number of grams gained by a helper per hour during a 24 hr day), can affect its contribution to pup care. Figure 2 shows how the percent contribution to babysitting and to pupfeeding by helpers older than 1 yr varied with daily weight gain.
