Presence of a dominant native shrub is associated with minor shifts in the function and composition of grassland communities in a northern savannah

Dataset for Peetoom Heida et al. (2021). There are 4 data files, one R code file, and a metadata file. <br>The Main_Data_File contains the core data for the study, with species data, soil chemistry, biomass and diversity measurements. <br>The Stem_Map file contains the spatial data for all wolf-willow stems found in the plot. Each stem has a location and several architectural measurements.<br>The Score_Input file is a subset of the Main_Data_File, containing all inputted measurements for the "Wolf-willow score" calculations from the study.<br>The pca_wwscore file contains the results of the ""Wolf-willow score" calculations from the study.<br>The SppRespCSV file contains the output from the generalized linear models run on species occurence in wolf-willow and grassland plots (Figure 5 in text).<br>The metadata file contains metadata for the above files, and includes units where applicable.<br>The R code contains all code needed to produce the analyses and figures in the manuscript.

本数据集对应Peetoom Heida等人（2021）的研究。数据集共包含4个数据文件、1个R代码文件与1个元数据文件。<br>主数据文件（Main_Data_File）包含本研究的核心数据，涵盖物种数据、土壤化学指标、生物量与多样性测定结果。<br>茎映射文件（Stem_Map）包含样地内所有银水牛果（wolf-willow）茎干的空间分布数据，每条茎干均记录了其空间位置与多项形态结构测定指标。<br>评分输入文件（Score_Input）为主数据文件的子集，包含本研究中“银水牛果评分”计算所需的全部输入测定数据。<br>主成分分析-银水牛果评分文件（pca_wwscore）包含本研究中“银水牛果评分”的计算结果。<br>物种响应CSV文件（SppRespCSV）包含针对银水牛果样地与草地样地中物种出现情况构建的广义线性模型输出结果，对应论文正文的图5。<br>元数据文件（metadata）包含上述所有文件的元数据，并在适用情况下标注了各指标的计量单位。<br>该R代码文件包含复现论文中所有分析与图表所需的全部代码。
