Operant Schedule

2 adult male squirrel monkeys, Saimiri sciureus, were conditioned on titration schedules of reinforcement which enabled the animals to adjust sucrose concentrations of Noyes 190-mg. food pellets received as reinforcers. Responding on a titration operandum increased available sucrose concentrations by 20% for 30 sec. per titration response. An alternate operandum, which required a response of different topography, produced reinforcers of sucrose concentration determined by titration rate under a FR 30 schedule. Regular insulin, U-40, was administered via the intraperitoneal route in four doses. Highest and lowest doses of insulin resulted in highest sucrose proportion acquired. Intermediate doses resulted in lowest sucrose proportion acquired.

Male Alliances

Abstract1. Male South American squirrel monkeys form groups whose composition remains stable over migrations between troops. These groups are called 'migration alliances'. 2. Members of migration alliances support one another against other males through coalitions in genital display bouts both during immigration and throughout the year. Male alliances do not function to overcome female dominance. 3. Seasonal reproduction in squirrel monkeys may influence male alliances by a) intensification of within-group competition during the mating season, and b) production of temporally and spatially fluctuating mating opportunities between groups.
