项目摘要

Behavioral and neuroendocrine variation in mammalian mating systemsJerry O. Wolff and Steven M. PhelpsSUMMARYThis research will examine individual and geographic variation in the expression of receptors for the hormone vasopressin, which affects monogamous mating in male prairie voles (Microtus ochrogaster). Vasopressin receptors affect affiliative and paternal behavior in males; this dual role may allow females to choose good fathers as mates. Preliminary evidence suggests that monogamous traits such as affiliation and paternal care are more common in a population of voles from Illinois and less common in voles from Tennessee. A series of field and laboratory experiments will be conducted on voles from these two locations to determine how vasopressin receptors affect individual differences in male fidelity, affiliation and paternal care. Experiments will also determine if females can assess differences in male affiliative behavior and select mates based on paternal characteristics. In addition to examining individual mate preferences, field experiments will be conducted to determine if this trait ultimately affects juvenile survival and population growth rates. This will be the first study to combine data at the level of gene expression, individual behaviors, mating system, field demography and population variation.

哺乳动物交配系统中的行为和神经内分泌变异。作者声明：Steven M. Phelps概述本研究将检测影响雄性草原田鼠（Microtus ochrogaster）一夫一妻制交配的激素加压素受体表达的个体和地理差异。后叶加压素受体影响男性的亲和和父性行为;这种双重作用可能使女性选择好的父亲作为配偶。初步证据表明，一夫一妻制的特点，如从属关系和父亲的照顾是更常见的人口田鼠从伊利诺伊州和不常见的田鼠从田纳西州。一系列的现场和实验室实验将进行田鼠从这两个地点，以确定加压素受体如何影响男性的忠诚度，从属关系和父亲照顾的个体差异。实验还将确定女性是否能够评估男性亲和行为的差异，并根据父亲的特征选择配偶。除了研究个体的择偶偏好外，还将进行实地实验，以确定这种特征是否最终影响少年的生存和人口增长率。这将是第一个在基因表达、个体行为、交配系统、田间人口统计学和种群变异水平上结合联合收割机数据的研究。
