Diversity-enhanced canopy space occupation and leaf functional diversity jointly promote overyielding in tropical tree communities

This dataset contains canopy space-filling, abundance, leaf traits and productivity data to identify the biodiversity-productivity relationships in the forest. The data were collected from the Sardinilla experiment in Panama in 2017. The analysis was done in subplots (4 subplots nested in 1 plot). Because of the high mortality (>85%) of C. alliodora in the first year of the experiment, the species' monoculture data is unavailable. Following that, C. alliodora available in 12 subplots in 2017 was excluded from the datasets.

本数据集涵盖林冠空间填充度、物种丰度、叶片性状及生产力数据，旨在探究森林生态系统的生物多样性与生产力之间的关联。该数据采集自2017年巴拿马萨尔迪利亚（Sardinilla）野外实验。数据分析以嵌套样地为单元开展，每个主样方嵌套4个副样地。因实验第一年中C. alliodora的死亡率超过85%，该物种的单作林样地数据未能获取。据此，2017年12个副样地中留存的C. alliodora相关数据被排除出本数据集。
