The similarity principle underlying social bonding among female rhesus monkeys

Twenty adult female rhesus monkeys (Macaca mulatta) were observed over a three-year period. They lived in a mixed captive group with kinship relations known for three generations. The study's aim was to test Seyfarth's [J. theor. Biol. 65: 671-698, 1977]...

Low light intensity decreases the fertility of Callithrix jacchus

Improvement of the light fixtures in both rooms doubled the lighting force and increased the breeding rate during the following 12 months approximately 20% in the upper and 130% in the lower cages.

Control and early socioemotional development: Infant rhesus monkeys reared in controllable versus uncontrollable environments

For the Master group, responses on the operant manipulanda resulted in the delivery of the appropriate reinforcements [food, water, treats]. For the Yoked group, the manipulanda were inoperative; the occurrence of reinforcements was dependent on the actions of the Master...

A benign method for maintaining ovulatory estrogen levels in cycling rhesus macaques

The goal of this study was to develop a relatively noninvasive technique for generating ovulatory estrogen levels in cycling females over extended periods of time. Eleven intact cycling rhesus macaques were given weekly injections of estradiol cypionate in an effort...

The effect of female proximity and social interaction on the menstrual cycle of crab-eating monkeys (Macaca fascicularis)

We designed a two-cage structure that housed each member of an experimental pair in a separate cage approximately 5.5 cm apart. Thus, each animal could either maintain a safe distance from the other or reach through the cage side to...

Acute restraint device for rhesus monkeys

One of the major drawbacks to the use of nonhuman primates is that they can be difficult and even dangerous to handle. Restraint is therefore necessary and desirable to protect both the investigator and the animal. During restraint procedures often...

Hair pulling-and-eating in captive rhesus monkeys

Hair pulling and eating has not yet received attention in the nonhuman primate literature. Hair pulling and eating was recorded 388 times in two heterogeneous troops of healthy rhesus monkeys that were kept according to modern management practices. The behavior...

Does intermale mounting function as a dominance demonstration in rhesus monkeys?

The relationship between dominance and intermale mounting was analyzed in two troops of captive rhesus monkeys. The data did not support the assumption that mounting among males functions as a dominance demonstration as described in the literature because (1) mounting...

Altruistic interference shown by the alpha-female of a captive troop of rhesus monkeys

Interferences in aggressive disputes were recorded in a captive troop of rhesus monkeys (Macaca mulatta) comprising 19 mature females, 2 mature males and 12 immatures. The top ranking animal – the oldest female, Alpha, 23 years of age – was...
