家鼠使用尿液标记进行各种形式的社交交流。尿液标记随着优势地位的不同而不同；社交优势雄性家鼠的尿液标记比那些社会从属的要多。实验一旨在证实这一先前的发现。实验二的目的是测试在测试男性攻击性之前测量的尿液标记是否可以用来预测社交优势。小鼠在20 cm×40 cm的矩形笼子里进行尿液标记测试，笼子底部有滤纸。在实验一中，四只雄鼠按循环法进行测试，以评估它们的社会优势，然后将它们单独放入尿液标记笼中。社会优势是包含尿痕的1厘米方块数量的重要预测因素，无论是就内部方块还是对于测试笼子中的周长方块而言。在实验二中，四组雄性首先在尿液标记笼中单独进行测试，然后用来进行循环赛，以评估社会优势。有尿痕的内部方格的数量，以及较小程度的有尿迹的周边方块的数量，都是攻击性分数和社会支配地位的显著预测因素。能够在不让老鼠相遇的情况下判断社会优势可能是未来工作的一个有价值的工具；在获得对男性社会优势地位的估计时，可以避免对激素水平等参数的混淆影响。(C)2001 Elsevier Science B.V.保留所有权利。
House mice use urine marking for a variety of forms of social communication. Urine marking varies with dominance status; socially dominant male house mice urine mark more than those that are socially subordinate. Experiment I was designed to confirm this previous finding. Experiment II was designed to test whether urine marking, measured prior to testing males for aggression, could be used to predict social dominance. Mice were tested for urine marking in 20 cm x 40 cm rectangular cages with filter paper below the wire mesh bottom of the cage. In Experiment I, groups of four males were tested in a round robin design to assess social dominance and were then placed individually in urine marking cages. Social dominance was a significant predictor of the number of 1 cm squares that contained urine marks, both with regard to interior squares and for perimeter squares in the test cage. In Experiment II, groups of four males were first tested individually in urine marking cages and then used for round robin aggressive encounters to assess social dominance. The number of interior squares with urine marks, and, to a lesser extent, the number of perimeter squares with urine marks, were both significant predictors of aggression scores and social dominance status. Being able to judge social dominance without having the mice encounter each other could be a valuable tool for future work; confounding effects on such parameters as hormone levels could be avoided while obtaining an estimate of male social dominance status.
