Ultraviolet light has been used to examine urine marks deposited by adult male house mice on filter paper on the floors of their cages during overnight tests. Both the urination frequency and the pattern in which urine was deposited on the filter paper depended upon social rank. Dominant males vigorously marked their entire cage floor, whereas subordinate males typically voided urine in only two to four pools in the corners of their cages.
在夜间测试期间，紫外线被用于检查成年雄性家鼠在其笼子地板上的滤纸上留下的尿液痕迹。排尿频率以及尿液在滤纸上的分布模式都取决于社会等级。占主导地位的雄性会用力标记整个笼子的地板，而从属雄性通常只在笼子角落的两到四个小水洼中排尿。
