Social dominance and serum testosterone concentration in dyads of male Macaca fascicularis

Of 16 pairs, five dyads had to have their composition changed at some point [of the 8-month study period] owing to excessive fighting. [Pair formation procedure is not described.] Testosterone concentration and dominance were associated according to the type of...

An Ecological and Behavioral Study of the Pig-Tailed Macaque

Excellent overview of the species-typical behavior of wild pig-tailed macaques. Groups did not appear to select particularly large or emergent trees, but sleeping sites tended to be clumped on the upper part of the hill (which is to say, away...

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...
