Plant functional traits measured at the individual level within four temperate wetland types (bog, fen, meadow, marsh) in North-East America.

We replicated a natural species richness gradient where communities included from 2 to 16 species within four wetlands (bog, fen, meadow, marsh) contrasting in plant productivity. We sampled functional traits from individuals in each community and used hierarchical distributional modelling in order to analyze the independent variation of the mean and dispersion of functional trait space at ecosystem, community and species levels.

我们复现了自然物种丰富度梯度，实验涵盖4种植物生产力存在显著差异的湿地类型——泥炭沼泽（bog）、富营养沼泽（fen）、草甸（meadow）、草本沼泽（marsh），各湿地内的群落包含2至16个物种。我们从每个群落的个体中采集功能性状数据，并采用分层分布建模方法，分析生态系统、群落及物种三个层级下功能性状空间的均值与离散度的独立变异规律。
