| Resumo: |
Infant care is known to impose high energetic costs on female primates because in addition to lactation, most primate mothers also provide transport for their offspring. Many studies have documented the high energetic costs of lactation, but less is known about energetic costs of infant carrying and their effects on the recovery of maternal physical condition. We compared the activities of female northern muriquis (Brachyteles hypoxanthus Kuhl, 1820) over a 12-month period at the RPPN Feliciano Miguel Abdala, Minas Gerais, Brazil to investigate whether mothers during their weaning year behaved differently than mothers in their post-weaning year, when they resumed reproductive cycling and copulating, and conceived again. We found no significant differences in the behavioral activity budgets of mothers in their weaning year (n = 4) versus post-weaning year (n = 5), despite the significantly higher proportion of time that mothers in their weaning year spent in close proximity with their infants and carrying their infants compared to mothers in their post-weaning year. We suggest that the energy budgets of weaning are similar to those of post-weaning in female northern muriquis.
