Beechcoste52 Database
收藏资源简介：
The BeechCOSTe52 includes phenotypic trait measurements from individual trees measured in an international network of provenance tests compiled by the COST Action E52 (2006 – 2010). It comprises 39 trial sites and 217 provenances covering the distribution of European beech (<em>Fagus</em><em> </em><em>sylvatica</em> L.). The BeechCOSTe52 database provides individual tree phenotypic measurements of height, diameter at breast height, basal diameter, mortality, spring and autumn leaf phenology. The following files are included: <strong>Fsylvatica.csv</strong>: individual tree measurements by trial and provenance of origin. <strong>Trials_coords.csv</strong>: geographical coordinates of the trials <strong>Prov_coords.cvs</strong>: geographical coordinates of the provenances <strong>BeechCOSTe52_metadata_descriptor.doc</strong><strong>x</strong>: description of the fields of Fsylvatica.csv, Trials_coords.csv and Prov_coords.cvs databases. <strong>Subset_by_trial.R</strong><strong>: </strong>R script to subset the original database (<strong>Fsylvatica.csv</strong>) by trial <strong>Merge_trial_prov-coords_individualmeasurements.R</strong>: R script to merge the coordinates of trials and provenances (<strong>Trials_coords.csv</strong><strong> </strong>and<strong> </strong><strong>Prov_coords.cvs</strong>) with the phenotypic measurements (<strong>Fsylvatica.csv</strong><strong>)</strong>. <strong>Plot_Trial-Prov_locations.R</strong><strong>:</strong> R script to map trial and provenance locations. <strong>Hplot.R</strong>: R script to map tree height variation across provenances and trials. <strong>Fagus_sylvatica_EUFORGEN.X:</strong> Shape files containing the distribution of Fagus sylvatica from EUFORGEN (http://www.euforgen.org)
BeechCOSTe52数据集包含由COST行动E52（2006–2010）汇编的国际种源试验网络中单株树木的表型性状测量数据。该数据集涵盖39个试验站点与217个种源，覆盖欧洲山毛榉（*Fagus sylvatica* L.）的自然分布范围。BeechCOSTe52数据库提供单株树木的多项表型测量指标，包括树高、胸径、基径、死亡率、春季与秋季叶片物候。 本数据集包含以下文件： 1. **Fsylvatica.csv**：按试验站点与起源种源整理的单株树木测量数据。 2. **Trials_coords.csv**：试验站点的地理坐标数据。 3. **Prov_coords.cvs**：种源的地理坐标数据。 4. **BeechCOSTe52_metadata_descriptor.docx**：Fsylvatica.csv、Trials_coords.csv及Prov_coords.cvs三个数据库的字段说明文档。 5. **Subset_by_trial.R**：用于按试验站点对原始数据库Fsylvatica.csv进行子集提取的R脚本。 6. **Merge_trial_prov-coords_individualmeasurements.R**：用于将试验站点与种源的坐标数据（Trials_coords.csv与Prov_coords.cvs）与表型测量数据（Fsylvatica.csv）进行合并的R脚本。 7. **Plot_Trial-Prov_locations.R**：用于绘制试验站点与种源分布位置的R脚本。 8. **Hplot.R**：用于绘制不同种源与试验站点间树高变异情况的R脚本。 9. **Fagus_sylvatica_EUFORGEN.X**：源自EUFORGEN（http://www.euforgen.org）的欧洲山毛榉分布范围矢量形状文件。
