加速计在实验室和野外都是监测各种龙虾物种活动的有用设备。虽然该方法已被证明对确定动物何时活动是有益的，但基于加速度计确定动物的实际旅行距离或运动强度更为困难。为了实现这一目标，我们在实验室中监测了美国龙虾Homarus americanus H.Milne-Edwards，1837，安装了Hobo加速计数据记录器和Vemco V13AP加速计发射器，同时获得了它们行为的延时数字视频。我们使用这些数据将加速度计输出转换为单位时间内移动的距离。这两种加速度计的输出都与行驶距离有很好的相关性。然后，我们使用相同的流浪汉加速度计，利用这些信息分析了在之前的研究中获得的数据。这使得计算活动和每小时旅行距离在一年中季节性变化的程度成为可能。这项分析还显示，在类似的围栏内，在一年中的同一时间，田野中的龙虾活动明显多于实验室中的活动。总体而言，这些结果表明，加速度法是一种适合于在实验室和野外长期监测龙虾相对活动的准确方法，其结果与其他已发表的龙虾运动研究相比是有利的。

Accelerometers are useful devices for monitoring the activity of a variety of lobster species, both in the laboratory and the field. While the method has proven beneficial for determining when animals are active, it is more difficult to determine the actual distance animals travel or the intensity of their movements based on accelerometry. To achieve this goal, we monitored American lobsters, Homarus americanus H. Milne-Edwards, 1837, fitted with HOBO accelerometer dataloggers and Vemco V13AP accelerometer transmitters in the laboratory and simultaneously obtained time-lapse digital videos of their behavior. We used these data to convert accelerometer outputs to distances moved per unit time. The outputs of both types of accelerometers were well correlated with distance traveled. We then used this information to analyze data obtained in a previous study, using the same HOBO accelerometers. This made it possible to calculate to what extent activity and the distance traveled per hour changed on a seasonal basis over a year. This analysis also revealed that lobster activity in the field was significantly greater than activity in the lab at the same time of year, within similar enclosures. Overall, these results demonstrate that accelerometry is a suitable and accurate method for monitoring the relative activity of lobsters over long periods in the laboratory and field and the results compare favorably with other published studies of lobster movements.
