For the experiment， the wheels were enclosed so that small animals could come and go but so that larger animals could not knock them over. Dr. Meijer set up motion sensors and automatic video ral years and 12，000 snippets of video later， she and Yuri Robbers， also a Leiden researcher， reported the results. They were released online Tuesday in the Proceedings ofthe Royal Society B.
为了进行试验，跑轮被围了起来，这样小动物就能来去自由，大动物则无法把它们撞翻。梅杰安放了运动传感器和自动摄影机。她和同为莱顿研究人员的尤里·罗伯斯（Yuri Robbers）报告称，几年后，他们获得了1.2万个视频片段。周二，这些结果被公布在了《英国皇家学报B》（Proceedingsof the Royal Society B.）的网站上。
