Accelerometers have been used to study both terrestrial and aquatic wildlife, mainly for mammal and bird species. In terrestrial mammals, there is a bias toward ungulates and carnivores, with fewer studies on nonhuman primates. In this study, we tested the use of accelerometers for studying the activity of Japanese macaques (Macaca fuscata). We modeled the activity of a male and a female subject by matching continuous focal observations from video recordings to sensor parameters derived from collar-mounted accelerometers. Models achieved classification performance (AUC) of greater than 90% for both subjects, with similar results when subjects were cross-validated. Accelerometer-based estimates of activity had comparable accuracies to estimates from instantaneous sampling at 1 min and 5 min intervals. We further demonstrated the use of model estimates for analyzing circadian rhythm and night time activity of M. fuscata. Our results add support to the feasibility of using accelerometers for studying activity of nonhuman primates. We discussed the limitations, benefits and potential applications of remote-sensing technology like accelerometers for advancing primalotogical studies.
加速度计已被用于研究陆生和水生野生动物，主要针对哺乳动物和鸟类物种。在陆生哺乳动物中，研究偏向于有蹄类动物和食肉动物，对非人类灵长类动物的研究较少。在本研究中，我们测试了使用加速度计来研究日本猕猴（Macaca fuscata）的活动情况。我们通过将视频记录中的连续焦点观察与从颈圈式加速度计得出的传感器参数相匹配，对一只雄性和一只雌性个体的活动进行建模。两个个体的模型分类性能（AUC）均大于90%，当对个体进行交叉验证时结果相似。基于加速度计的活动估计与1分钟和5分钟间隔的瞬时采样估计具有相当的准确性。我们进一步展示了使用模型估计来分析日本猕猴的昼夜节律和夜间活动。我们的结果为使用加速度计研究非人类灵长类动物的活动的可行性提供了支持。我们讨论了像加速度计这样的遥感技术在推进灵长类动物学研究方面的局限性、益处和潜在应用。
