* Title Community level leaf C:N ratio in Mydiv in 2021
* Abstract The leaf quality was proposed as a potential mediator to understand the mechanisms underlying the effects of tree species richness and mycorrhizal types on the multitrophic ecosystem functions. The leaf C and N concentrations of three trees for each species in every plot were measured in July 2021 in the MyDiv experiment. The averaging leaf C:N ratio of all species was used as the proxy of leaf quality in every plot. This data was used in the study by Yi et al. (2023) published in the Journal of Ecology

Detailed study design
Measurements *
* Sampling design To measure leaf C and N concentrations as a proxy of leaf quality, we sampled three leaves (without any damage from herbivores or pathogens) at 2.5 m height per tree and three individuals for each species per plot in July 2021 (Cadotte, 2017). Nine leaves for each species per plot were pooled into one sample.
Sample preparation All samples were dried at 60℃ to constant weight, and each sample was ground with a ball mill (MM 400, Retsch, Haan, Germany) to a homogeneous powder.
Sample analysis Five mg from each sample were used to determine leaf total C and total N concentrations with a CHNS elemental analyzer (vario EL cube; Elementar Analysensysteme GmbH, Hanau, Germany).
