Shifts and linkages of functional diversity between above- and below-ground compartments along a flooding gradient

Trait-based approaches have the potential to reveal general and predictive relationships between organisms and ecosystem functioning. However, the mechanisms underlying the functional structure of communities are still unclear. Within terrestrial ecosystems, several studies have shown that many ecological processes are controlled by the interacting above- and below-ground compartments. However, few studies have used traits to reveal the functional relationships between plants and soil fauna. Mostly, research combining plants and soil fauna solely used the traits of one assemblage in predictive studies. Above-ground (plants) and below-ground (Collembola) compartments were sampled over a flooding gradient in northern France along the Seine River. First, we measured the effect of flooding on functional and taxonomic assembly within both communities. We then considered the linkages between plant and Collembolan species richness, community traits and assessed whether traits of both compartm...基于功能性状的研究方法（Trait-based approaches）具备揭示生物与生态系统功能间普适性、可预测关联的潜力。然而，群落功能结构的潜在调控机制仍未明晰。在陆地生态系统中，已有多项研究表明诸多生态过程受地上与地下分室的交互作用调控，但目前鲜有研究借助功能性状阐释植物与土壤动物间的功能联系。过往结合植物与土壤动物的研究，在预测性分析中大多仅采用单一类群的功能性状。 本研究沿法国北部塞纳河沿岸的水淹梯度，对地上（植物）与地下（弹尾纲（Collembola））分室进行了采样。首先，我们测定了水淹对两类群落的功能组装与分类学组装的影响；随后，我们探究了植物与弹尾虫物种丰富度、群落功能性状之间的关联，并评估了两类分室的性状是否……
