Nitrogen and phosphorus enrichment differentially affect grassland ecosystem functioning via multi-trophic pathways

The enrichment of nutrients (e.g., N and P) is crucial in shaping the links between diversity and ecosystem functions. Previous research has mainly focused on how nutrient enrichment affects community diversity and composition within a single trophic level, such as plants or soil microbial communities. However, how nutrient enrichment affects community composition and diversity across multiple trophic levels and ecosystem functions has not been extensively explored. By conducting two long-term N- and P-enrichment experiments in temperate steppes, we explored the response of diversity and composition at both the community and functional group level across the soil food webs to nutrient enrichment, as well as their relationship with ecosystem functions. We found that the responses of soil biota and plants to nutrient enrichment varied depending on the community and functional group. N-enrichment resulted in a decrease in plant and bacterial richness at both the community and functional gr..., , # Nitrogen and phosphorus enrichment differentially affect grassland ecosystem functioning via multi-trophic pathways

The dataset consists of an NP_Data.xlsx and an R code file (R_code.txt). Sheet 1 was the dataset for all raw data. The dataset contains 113 variables for Sheet 1. NA in the dataset indicates missing data for the relevant variable.
