Abstract

Male prairie vole preferences for estrous versus diestrous females and associated stimuli were investigated. The role of sexual experience in engendering preferences proved more complex than reported for other species. Naive males did not display preferences. Neither males receiving sexual experience through monogamous cohabitation, nor males housed with two females displayed preferences. Males exposed to both estrous and diestrous females, and males housed with other males and females in a semi-naturalistic setting, displayed preferences. Thus, preferences seem to be "tuned" by experiential manipulations. Cues available for discrimination also influenced the display of preferences, as different results were obtained using apparatus that differed in cue availability. The observed pattern of responsiveness to sex odors may be related to the social organization and mating system of the prairie vole, a mammal that is believed to be monogamous.

摘要

对雄性草原田鼠对处于发情期与非发情期的雌性及相关刺激物的偏好进行了研究。性经验在产生偏好方面所起的作用比其他物种的情况更为复杂。未接触过的雄性没有表现出偏好。通过一夫一妻制同居获得性经验的雄性，以及与两只雌性一起饲养的雄性，均未表现出偏好。接触过发情期和非发情期雌性的雄性，以及在半自然环境中与其他雄性和雌性一起饲养的雄性，表现出了偏好。因此，偏好似乎是由经验操纵“调节”的。可供辨别用的线索也影响了偏好的表现，因为使用线索可得性不同的实验装置会得到不同的结果。观察到的对性气味的反应模式可能与草原田鼠的社会组织和交配系统有关，草原田鼠是一种被认为实行一夫一妻制的哺乳动物。
