Rates of survival, infant growth and fertility of rhesus monkeys with two, one and no C allele(s) at the transferrin locus are compared. Infants with no C allele experience slower growth rates than animals with either one or two C allele(s). While heterozygous females exhibit the highest infant growth rates among females, their fertility is lower and(More)
Using weight and skinfold thickness to calculate relative body fat, the fat content of 21 captive female rhesus macaques was estimated. Although age and. pregnancy had no effect on fat, rank was significant, especially during winter, with high-rank females having the highest fat scores. Rank therefore has a significant effect on the health of captive(More)
A captive group of rhesus macaques (Macaca mulatta) was observed during the breeding season to determine if consortship behavior, rather than promiscuous matings, resulted in higher reproductive success for either partner. The 38 adult females in this group were observed “in consort” with the 5 adult or 4 subadult males on 179 occasions. Most of these(More)
9 adult rhesus macaque females (Macaca mulatta) and 7 adult bonnet macaque females (Macaca radiata) were observed during the birth season to identify possible differences between mothers and nonmothers in time budgets and social interactions. Rhesus mothers spent less time moving, feeding, grooming others and aiding others than rhesus nonmothers did. Bonnet(More)
The hypothesis that the matrilineal affiliation of 410 infants born in three captive groups of rhesus macaques is independent of the patrilineal affiliation of these infants was tested. Preferential mating with particular patrilines was observed for matrilineal members. We conclude that lineage affiliation does influence mate choice of rhesus macaques, at(More)
The possibility that male offspring are more costly to produce than female offspring was investigated in captive Macaca mulatta. Differential maternal investment into 187 infants was evaluated by comparing birth weight, infant growth rate, month of birth, and interbirth interval of males and females. There were no statistically significant differences(More)
Bonnet (Macaca radiata) and rhesus (Macaca mulatta) macaque females were observed during the breeding season to evaluate differences in mating strategies between females without infants and females with dependent offspring. Rhesus nonmothers participated in consortships earlier in the breeding season and initiated and received more approaches with adult(More)
