Analogous above- and belowground traits for twelve boreal tree species

It is heavily debated whether analagous aboveground and belowground traits are coordinated. Here, we collected trait data (above- and belowground) for twelve boreal forest tree species to assess trait coordination in leaves and roots. We find only partial evidence for above-belowground coordination for \"fast-slow economic traits\", such that N content and dry matter content were positively correlated with each other. However, root dry matter content and leaf N had no significant relationship. For reseource acquisition traits we found no strong evidence for trait cordination, as specific root length and specific leaf area were not positively correlated.Site explained little of the total trait variation, whereas within-site variation contributed substantially to the total trait variation for a large number of traits, more so for morphological root traits than leaf traits., , , # Analogous above- and belowground traits for twelve boreal tree species

## Description of the data and file structure

The data were collected at two sites within Sweden (one northern and one central site). In this dataset, the northern site is Vindeln (abbreviated \"VI\") and the central site was located in Garpenberg (abbreviated \"GA\"). Each site consisted of 3 blocks each with plots consisting of monocultures of twelve different species. Six species were common between the two sites. In the dataset, the species are Pinus contorta (CO), Pseudotsuga menziesii (DO), Picea abies (SP), Larix sibirica (LS), Betula pendula (BI), Pinus sylvestris (PN), Larix sp. (LH), Picea glauca (WS), Picea mariana (PM), Abies lasciocarpa (AL), Abies sibirica (AS), and Pinus banksianna (PB). The measured traits and their units are leaf carbon content (C_Leaf; %); leaf nitrogen content (N_Leaf; %); specific leaf area (SLA; c...

长期以来，学界围绕地上（aboveground）与地下（belowground）对应性状是否存在协同关联存在广泛争议。本研究收集了12种北方针叶林（boreal forest）树木的地上与地下性状数据，以评估叶片与根系的性状协同模式。我们仅发现部分证据支持“快速-慢速经济谱性状”的地上-地下协同：即氮含量与干物质含量呈显著正相关。然而，根系干物质含量与叶片氮含量并无显著关联。针对资源获取类性状，我们未发现显著的性状协同证据：比根长（specific root length）与比叶面积（specific leaf area, SLA）并未呈现正相关关系。样地对总性状变异的解释度极低，而样地内变异对多数性状的总变异贡献显著，其中形态学根系性状的样地内变异贡献度高于叶片性状。
