Dataset of the paper: Warming Weakens Soil Nitrogen Stabilization Pathways Driving Proportional Carbon Losses in Subarctic Ecosystems
This dataset contains measurements of nitrogen (N) and carbon (C) pools in various ecosystem compartments (e.g., bulk soil, roots, aboveground vegetation, microbial biomass) from a subarctic grassland in Iceland subjected to a long-term soil warming experiment. Data were collected across four season...

| Sumario: | This dataset contains measurements of nitrogen (N) and carbon (C) pools in various ecosystem compartments (e.g., bulk soil, roots, aboveground vegetation, microbial biomass) from a subarctic grassland in Iceland subjected to a long-term soil warming experiment. Data were collected across four seasons (summer, autumn, snowmelt, and spring) and include results from a 15N amino acid tracer study designed to evaluate seasonal and warming-induced changes in nitrogen retention and stabilization. Each row in the dataset corresponds to a specific plot, season, and ecosystem pool, and includes measured variables such as total N and C content (mg/m²), 15N enrichment (atom percent excess), C:N ratios, and tracer recovery percentages. The dataset also includes metadata on soil temperature treatments and flags for statistical outliers. These data were used in the manuscript “Warming Weakens Soil Nitrogen Stabilization Pathways Driving Proportional Carbon Losses in Subarctic Ecosystems” and support analyses of N cycling dynamics under climate warming. |
