Description
Hui An's dataset contains results from a 7-year field experiment in a desert grassland, manipulating nutrient addition (nitrogen, phosphorus, potassium) and precipitation change (±50%). It quantifies how plant functional component assembly, including species turnover and intraspecific trait variation, regulates the stability of aboveground, belowground, and total biomass. The data supports analysis of how precipitation and nutrient enrichment influence biomass stability through different trait-assembly pathways.
Use Cases
Modeling aboveground biomass stability based on precipitation change and species turnover metrics.
Analyzing belowground biomass stability responses to nutrient addition and intraspecific trait variation.
Investigating interactions between nutrient enrichment and increased precipitation on total biomass stability.
Studying the role of leaf economic spectrum strategies (conservative vs. acquisition) in mediating biomass stability.
Strengths
Data originates from a controlled 7-year field experiment, providing longitudinal insights.
Measures three distinct aspects of plant trait structure: species turnover, intraspecific trait variation, and leaf economic spectrum strategies.
Released under a permissive CC-BY-4.0 license, facilitating reuse.
Limitations
Column names and a precise row count are not provided in the available metadata, limiting understanding of the data structure.
The dataset's size is given as 183358 (likely bytes), but its exact dimensions and variable count are unknown.
The description is duplicated across platform entries, suggesting potential for incomplete or non-standardized metadata.
