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 کامل: ) ' ( - ~ Sameness - Difference Judgments in Saimiri Sciureus
The rationale was to apply Piaget's theory and methods to the study of the phylogenetic development of cognitive abilities. It was asked whether squirrel monkeys have the prerequisite skills for conservation of quantity, and, specifically, whether they might respond differentially to equivalent and· unequivalent volumetric cues. All monkeys responded significantly and differentially to pairs of...
متن کاملConditional discrimination with conceptual simultaneous and successive cues in the squirrel monkey (Saimiri sciureus).
At the end of several stages of training, 4 squirrel monkeys met an 87% criterion for choosing correctly between exemplars of the concept "sameness" and the concept "difference," the simultaneous cues, as a function of having been cued by an exemplar either of the concept "triangularity" (cued sameness) or "heptagonality" (cued difference), the successive cues, which were presented in random or...
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 کاملSubcutaneous Leiomyosarcoma in a Common Squirrel Monkey (Saimiri sciureus).
Leiomyosarcoma in soft tissue has only been reported in humans or animals. We performed pathological examination of a 3-years-old male squirrel monkey which had a large mass in the right axilla. The mass in the right axilla was surgically resected but it soon reoccurred. This tumor was diagnosed as a leiomyosarcoma based on histopathology and immunohistochemistry using the expression of alpha-s...
