Community Weighted Mean Trait Data

This file contains the data used the community weighted mean trait analyses, with the exception of climate data which was obtained from DAYMET (Thornton et al. 2012). The “Site_Plot” column lists the site and plot identifier where the data were collected. “Date” gives the date that the trait measurements were collected. “Elevation” is the height (cm) of the center of the plot above the nearest stream. “Bulk Density” is the plot soil bulk density (g/cm3). “Days Since Burn” is the number of days since the last fire. “Shannon Index” gives the Shannon Diversity Index, H. The remaining columns give the community weighted mean SLA (g/cm3) and LDMC (%) based on the landscape level species trait averages and the plot level species values.本数据集包含用于群落加权平均性状分析的全部数据，气候数据除外——该部分数据取自DAYMET（Thornton等，2012）。"Site_Plot"列列出了数据采集所在的样地与地块标识符；"Date"列记录了性状测量的采集日期；"Elevation"列表示地块中心相对于最近溪流的海拔高度（单位：厘米）；"Bulk Density"列对应地块的土壤容重（单位：克/立方厘米）；"Days Since Burn"列代表自上次火灾以来的天数；"Shannon Index"列对应香农多样性指数（Shannon Diversity Index）H；剩余列则基于景观尺度的物种性状平均值与地块尺度的物种数值，给出了群落加权平均比叶面积（Specific Leaf Area，SLA，单位：克/平方厘米）与叶干物质含量（Leaf Dry Matter Content，LDMC，单位：%）。
