Seasonality in squirrel monkeys (Saimiri sciureus): social facilitation by females.
The extent to which social living arrangements influenced seasonal changes in physiology and behavior was examined in adult squirrel monkeys (Saimiri sciureus). Data were collected over 20 months (encompassing two breeding seasons) from animals that were housed in three mixed-sex social configurations that varied in the number of heterosexual and isosexual social partners. For both sexes, the p...
متن کاملHorizontal transmission of Toxoplasma gondii in squirrel monkeys (Saimiri sciureus).
The possibility of horizontal transmission of T. gondii was examined in squirrel monkeys. After three monkeys were inoculated perorally with 1.1-2.1 x 10(3) cysts of the T. gondii ME49, the animals were divided into two cages and maintained with one normal monkey for each cage as a cagemate. Two out of the three T. gondii-inoculated monkeys died, and the remaining one monkey was sacrificed in a...
متن کاملAnnual physiological changes in individually housed squirrel monkeys (Saimiri sciureus).
This study investigated whether annual changes in physiology occur in individually housed squirrel monkeys (Saimiri sciureus). Physiological measures were monitored for 20 months. Over the course of the study, all individually housed males and females exhibited clear annual changes in gonadal and adrenal hormone levels, and males exhibited species-typical changes in body weight. Females exhibit...
متن کاملEnzootic toxoplasmosis in caged squirrel monkeys Saimiri sciureus.
Spontaneous and experimental toxoplasmosis have been reported sporadically as the cause of death in nonhuman primates. These reports indicate that New World monkeys and marmosets (cebidae and hapalidae), are more susceptible to infection by Toxoplasma gondii, or more often develop disease in response to this infection than monkeys and baboons of the Old World (cercopithecidae). This difference ...
متن کاملFlexibility in the use of requesting gestures in squirrel monkeys (Saimiri sciureus).
Three squirrel monkeys, trained to make a requesting gesture, were tested in the presence of a human assistant whose visual attention varied across trials. When food was available in one dish and an empty dish was nearby, the monkeys pointed overwhelmingly toward the former, regardless of where the assistant was looking. Looking at the assistant while pointing ("monitoring") peaked when she loo...
