All data and analyses of the manuscript are available here.<br>please download all files to the same working directory for running the R script. Below a brief description of each file<br>1. 'seed_mass_experiment_main_script.R' - this R script includes all the analyses presented in the paper. 2. 'slope_abundance.csv' - this dataset describes community abundance in southern slope along soil depth gradient in Beit Guvrin (described in Kadmon &amp; Ron 2018) the data was collected in four soil depth categories 3. 'slope_seed_mass.csv' - this dataset include seed mass data (in mg) for all species in 'slope_abundance.csv'(mass of zero means no available data)4. 'valley_abundance.csv' - this dataset describes community abundance in northern slope and valley in Beit Guvrin (described in DeMalach et al. 2017) the data was collected in two habitats (northern slope and valley) and include also fertilization and removal manipulation (these manipulations were not analyzed in this manuscript)5. 'valley_seed_mass.csv' - this dataset includes seed mass data(in mg) for all species in 'valley_abundance.csv' (mass of zero means no available data)6. 'mesocosm_abundance.csv' - this dataset describes community abundance in mescosom experiment in Jerusalem (described in Kadmon &amp; Ron 2018) the data was collected for four years in four soil depth categories7. 'mesocosm_seed_mass.csv' - this dataset include seed mass data (in mg) for all species in 'mesocosm_abundance.csv' (mass of zero means no available data)8. 'clipping_abundance.csv' - this dataset describes community abundance in clipping experiment in Beit Guvrin (described in Segre et al. 2016) The dataset include only the third year of the experiment9. 'clipping_seed_mass.csv' - this dataset include seed mass data (in mg) for all species in 'clipping_abundance.csv' (mass of zero means no available data)10.'greenhouse.csv' - this dataset include data on biomass (in mg) of the species in the greenhouse experiment. This include seed mass, shoot biomass after45 days and root and shoot biomass at the end of the experiment. <br><br>contact me for any question:<br>[e-mail]本论文手稿的全部数据与分析代码均可在此获取。请将所有文件下载至同一工作目录，以运行R脚本。 以下为各文件的简要说明： 1. `seed_mass_experiment_main_script.R`：该R脚本包含论文中呈现的全部分析代码。 2. `slope_abundance.csv`：该数据集记录了贝特古夫林（Beit Guvrin）南坡沿土壤深度梯度的群落多度数据（详见Kadmon & Ron, 2018），数据按4个土壤深度类别采集。 3. `slope_seed_mass.csv`：该数据集包含`slope_abundance.csv`中所有物种的种子质量数据（单位：mg），其中质量值为0代表无可用数据。 4. `valley_abundance.csv`：该数据集记录了贝特古夫林（Beit Guvrin）北坡与河谷的群落多度数据（详见DeMalach et al., 2017），数据采自2种生境（北坡与河谷），同时包含施肥与移除操作的相关记录（本手稿未对这些操作进行分析）。 5. `valley_seed_mass.csv`：该数据集包含`valley_abundance.csv`中所有物种的种子质量数据（单位：mg），其中质量值为0代表无可用数据。 6. `mesocosm_abundance.csv`：该数据集记录了耶路撒冷（Jerusalem）中宇宙实验（mesocosm）中的群落多度数据（详见Kadmon & Ron, 2018），数据按4个土壤深度类别采集，时长为4年。 7. `mesocosm_seed_mass.csv`：该数据集包含`mesocosm_abundance.csv`中所有物种的种子质量数据（单位：mg），其中质量值为0代表无可用数据。 8. `clipping_abundance.csv`：该数据集记录了贝特古夫林（Beit Guvrin）刈割实验中的群落多度数据（详见Segre et al., 2016），仅包含实验第3年的观测数据。 9. `clipping_seed_mass.csv`：该数据集包含`clipping_abundance.csv`中所有物种的种子质量数据（单位：mg），其中质量值为0代表无可用数据。 10. `greenhouse.csv`：该数据集包含温室实验中各物种的生物量数据（单位：mg），内容包括种子质量、培养45天后的地上生物量，以及实验结束时的地上与地下生物量。 如有任何疑问，请联系：[e-mail]
