Fecal particle size data of "Variation in chewing efficiency of Yakushima Japanese macaque (<i>Macaca fuscata yakui</i>)"

This dataset includes the data we used for the analysis in the published article (HE et al., 2020; 10.1002/ajpa.23955). The meaning of each column is listed below: No: Identification number of the sample. dmean: The discrete mass particle size of each sample. We followed a previous study (Fritz et al., 2012) for its calculation. p0: The proportion of the finest particles in each sample (Please refer to He et al., 2020 for its calculation method). altitude: The GPS-recorded altitudes of the collection positions. Some GPS records are missing. We marked their altitude as "NA" region: The altitudinal zone each sample belongs to. It is designated based on field observation of vegetation during collection. date: Date of collections. season: Seasons of sample collections. Spring, March-May; summer, June-August; autumn, September-November; winter, December-February.本数据集包含我们用于已发表学术论文（HE等人，2020；DOI: 10.1002/ajpa.23955）中的分析数据。 各列含义如下： No：样本标识编号。 dmean：各样本的离散质量粒径，其计算方法参照既往研究（Fritz等人，2012）。 p0：各样本中最细颗粒的占比，计算方法详见He等人2020年的研究。 altitude：采样点位的GPS记录海拔。部分GPS记录缺失，我们将其海拔标记为"NA"。 region：样本所属的海拔带，基于采样期间的野外植被观测结果划定。 date：样本采集日期。 season：样本采集季节，其中春季为3月至5月，夏季为6月至8月，秋季为9月至11月，冬季为12月至次年2月。
