| We assessed the genetic diversity of two northern muriqui (Brachyteles hypoxanthus Primata, Atelidae) populations, the Feliciano Miguel Abdala population (FMA, n = 108) in the Brazilian state of Minas Gerais (19°44' S, 41°49' W) and the Santa Maria de Jetibá population (SMJ, n = 18) in the Brazilian state of Espírito Santo (20°01' S, 40°44' W). Fecal DNA was isolated and PCR-RFLP analysis used to analyze 2160 bp of mitochondrial DNA, made up of an 820 bp segment of the gene cytochrome c oxidase subunit 2 (cox2, EC 1.9.3.1), an 880 bp segment of the gene cytochrome b (cytb, EC 1.10.2.2) and 460 bp of the hypervariable segment of the mtDNA control region (HVRI). The cox2 and cytb sequences were monomorphic within and between populations whereas the HVRI... |

| 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... |
