Diversity in resource use strategies promotes productivity in young planted tree species mixtures

This dataset compiles measurements from 21 experimental tree diversity sites within the TreeDivNet network across temperate, Mediterranean, and tropical biomes on five continents. It includes data on species richness, composition, traits (wood density, leaf nitrogen content), functional and structural diversity, and stand- and species-level productivity in 1,609 plots. Net biodiversity effects and their partitioning into selection and complementarity effects are also provided. The data can be reused to study biodiversity–productivity relationships, trait–function linkages, and forest ecosystem functioning across biomes. , , # Data from: Diversity in resource use strategies promotes productivity in young planted tree species mixtures The database contains four main data files and this README file, each corresponding to a hypothesis tested in the associated article: * README.md * DS1.xlsx * DS2.xlsx * DS3.xlsx * DS4.xlsx Missing values are noted as \"n/a\". #### **File: DS1** Plot-level dataset used to address hypothesis 1. | Variable | Description | Unit | | --------------------------------- | --------------------------------------- | ------------ | | Experiment | Experiment ID | - | | Block | Unique block ID | - | | Plot | Unique plot ID | - | | Species\_richness | Number of tree species in a plot | - | | Species\_compositio...,本数据集整合了TreeDivNet网络内覆盖五大洲温带、地中海及热带生物群系的21个林木多样性试验站点的实测数据，共包含1609个样地的物种丰富度、物种组成、功能性状（木材密度、叶片氮含量）、功能与结构多样性，以及林分和物种水平的生产力数据。此外还提供了净生物多样性效应及其分解为选择效应与互补效应的相关结果。该数据集可被复用开展跨生物群系的生物多样性-生产力关系、性状-功能关联以及森林生态系统功能相关研究。 # 数据来源：资源利用策略多样性促进人工栽植幼龄混交树种的生产力 本数据库包含四个主要数据文件与本说明文件，分别对应关联论文中验证的四项研究假说： * README.md * DS1.xlsx * DS2.xlsx * DS3.xlsx * DS4.xlsx 缺失值以"n/a"标注。 #### **数据集文件：DS1** 用于验证假说1的样地水平数据集。 | 变量名 | 描述 | 单位 | | --------------------------------- | --------------------------------------- | ------------ | | Experiment | 试验编号 | - | | Block | 唯一区组编号 | - | | Plot | 唯一样地编号 | - | | Species_richness | 样地内林木物种数量 | - | | Species_compositio...,
