The ontogenesis of hemoglobins in Macaca nemestrina.
Macaca nemestrina have two fetal hemoglobins which differ in the structures of their .y chains. Thus animals of this species, like man, appear to possess duplicate y-chain loci. In this study, the ontogenesis of hemoglobins in M. nemestrina was followed in animals ranging in age from the 60th day of gestation to adulthood. Fetuses in the 60th day of gestation had the two fetal hemoglobins and a...

In some species of Cercopithecine primates\ unrelated adult males and females maintain a.liative relationships "{friendships|# that are apparently unrelated to mating or parental care[ This study investigated the occurrence of friendships in a captive group of pigtail macaques\ and some of their possible determinants[ Study subjects were six adult males and 04 adult females with their newborn i...
متن کاملMaternal encouragement of infant locomotion in pigtail macaques, Macaca nemestrina
This study investigated whether pigtail macaque mothers encourage their infants’ independent locomotion by increasing distance from them and displaying a retrieval signal, the pucker face. Fifteen mother–infant pairs living in a large captive social group were focally observed during the first 12 weeks of infant life. Mothers puckered to their infants only when out of contact with them, and the...
متن کاملTRIMCyp expression in Old World primates Macaca nemestrina and Macaca fascicularis.
Primates have evolved a variety of restriction factors that prevent retroviral replication. One such factor, TRIM5alpha, mediates a postentry restriction in many Old World primates. Among New World primates, Aotus trivirgatus exerts a similar early restriction mediated by TRIMCyp, a TRIM5-cyclophilin A (CypA) chimera resulting from a CypA retrotransposition between exons 7 and 8 of the TRIM5 ge...
متن کاملMacaques (Macaca nemestrina) recognize when they are being imitated.
This study investigated whether monkeys recognize when a human experimenter imitates their actions towards an object. Two experimenters faced 10 pigtailed macaques, who were given access to an interesting object. One experimenter imitated the monkeys' object-directed actions, the other performed temporally contingent but structurally different object-directed actions. Results show a significant...
