Interactive effects of plant litter type and yak excrement on litter decomposition in a shrub-encroached alpine meadow

In the plant community with a shrub-grass mosaic, the main types of litter include herbaceous litter and its mixed forms with shrub leaves and stems. However, the quantitative relationship between the litter composition type and the litter decomposition, as well as how these processes are influenced by grazing activities (e.g., excrement deposition), remains largely unexplored. 
Herein, a three-year litter incubation experiment was conducted in a shrub-encroached alpine meadow. We aimed to elucidate the individual and interactive effects of litter type (solely grass litter (L), a mixture of grass litter and shrub leaves (L1), and a mixture of grass litter, shrub leaves, and shrub stems (L2)) and yak excrement addition (no addition, addition of dung only, addition of urine only, addition of both dung and urine) on the litter decomposition rate and nutrients release. Additionally, the initial chemical quality of litter, soil microclimate, soil nutrients, and soil microbial attributes..., , # Interactive effects of plant litter type and yak excrement on litter decomposition in a shrub-encroached alpine meadow

## Description of the data and file structure

This dataset has two .csv files with (1: Plant litter remaining, 2: Initial quality of litter) in the article, specifically as follow:

For the data of Plant litter remaining, the variations include Dry matter residual mass (g), Hemicellulose ...,

在灌草镶嵌型（shrub-grass mosaic）植物群落中，枯落物（litter）主要类型包括草本枯落物，以及其与灌丛枝叶混合形成的复合枯落物。然而，枯落物组成类型与枯落物分解之间的定量关系，以及放牧活动（如粪便沉积（excrement deposition））如何调控这一过程，目前仍未得到充分研究。

本研究在灌丛入侵（shrub-encroached）的高寒草甸中开展了为期三年的枯落物培养实验，旨在阐明枯落物类型[仅草本枯落物（L）、草本枯落物与灌丛叶片混合（L1）、草本枯落物与灌丛枝叶混合（L2）]与牦牛粪便（yak excrement）添加处理[无添加、仅添加牦牛粪便、仅添加牦牛尿液、同时添加粪便与尿液]对枯落物分解速率及养分释放的单独效应与交互效应。此外，本研究还涵盖枯落物初始化学品质、土壤微气候、土壤养分及土壤微生物属性……
