本研究的目的是确定雌性棕色旅鼠是否会选择性地与占优势的同种雄性交配。在二元遭遇，发情期女性与占主导地位的男性进行更频繁的脊柱前凸和接触的社会行为比那些与下属男性配对。占主导地位的男性和下属的安装和推力分数没有显着差异。当女性同时获得拴主导和下属男性，他们花了更多的时间在接近主导男性，避免与下属男性接触。交配得分较高占主导地位的男性。在与自由活动的主导和从属男性的三重接触中，发情期女性花更多的时间接近，并与主导男性进行更多的性行为。雄性间的竞争性相互作用导致了优势男性对女性的特权。性行为得分较低，有一个10倍的增加，在三重接触女性和陌生的占主导地位和从属地位的男性之间的男性间的侵略。雄性间的竞争相互作用和女性的选择行为占主导地位的男性的差异交配成功。
The objective of this study was to determine whether female brown lemmings would selectively mate with dominant conspecific males. In dyadic encounters, estrous females paired with dominant males engaged in more frequent lordosis and contact social behaviors than those paired with subordinate males. The mount and thrust scores of dominant and subordinate males did not differ significantly. When females had simultaneous access to tethered dominant and subordinate males, they spent more time in close proximity to dominant males and avoided contact with subordinate males. Copulation scores were higher with dominant males. In triadic encounters with free-moving dominant and subordinate males, estrous females spent more time near, and engaged in more sexual behavior with dominant males. Intermale agonistic interactions resulted in privileged access to females by dominant males. Sexual behavior scores were lower and there was a 10-fold increase in intermale aggression in triadic encounters between females and unfamiliar dominant and subordinate males. Both intermale agonistic interactions and female choice behavior accounted for the differential copulatory success of dominant males.
