The running-wheel behavior of white-tailed antelope squirrels was studied in the laboratory by quantitative analysis of wheel revolutions and by visual inspection of video recordings with the assistance of Google Nest's detection algorithm. There was great interindividual diversity of running styles, although no systematic difference was found between male and female squirrels. Some animals ran on the outside of the wheel instead of inside, some ran consistently inside the wheel but alternating directions every few seconds, some ran on a virtual wheel while avoiding the actual wheel and doing back flips in the air instead, and some ran around the cage and occasionally hit the wheel thus generating a stable record of wheel revolutions. On average, the squirrels woke up an hour after lights-on, started activity on the running wheel about 40 minutes later, ran for 10 hours covering a distance of 2 km, and fell asleep about an hour after lights-off. This pattern of running-wheel behavior partially resembles that of laboratory mice, but its extreme diversity is unique to this species.

羚羊地松鼠跑轮行为的不同风格

在实验室中，通过车轮转数的定量分析和视频记录的视觉检查，在谷歌 Nest 检测算法的帮助下，研究了白尾羚羊松鼠的跑轮行为。尽管在雄性和雌性松鼠之间没有发现系统性差异，但个体之间的跑步方式差异很大。有些动物跑在轮子的外侧而不是内侧，有些动物一直在轮子里面跑，但每隔几秒就会改变方向，有些动物在虚拟轮子上跑，同时避开实际轮子并在空中做后空翻，还有一些跑来跑去保持架并偶尔撞击车轮，从而产生稳定的车轮转数记录。平均而言，松鼠在开灯后一小时醒来，大约40分钟后开始在跑轮上活动，跑了10个小时，跑了2公里，熄灯大约一个小时就睡着了。这种跑轮行为模式部分类似于实验室老鼠，但其极端的多样性是该物种所独有的。
