Data from: Morphological constraints on plant-mediated methane release and oxidation under experimental warming in a peatland and meadow on the Qinghai-Tibetan Plateau

This dataset comprises measurements of plant-mediated methane (CH₄) and
carbon dioxide (CO₂) fluxes from an alpine meadow and a peatland on the
Qinghai-Tibetan Plateau. It includes flux measurements from 45 plant
species in the alpine meadow and 7 species in the peatland, collected
during the peak growing season of 2023. The dataset records gas flux
values (CH₄ and CO₂) derived from shoot-level enclosures, alongside key
plant traits such as leaf area (LA_m²), dry biomass (DB), and
environmental variables including temperature and treatment type (e.g.,
control, warming treatments). Additional normalized flux metrics (fluxLA,
fluxDB) are provided to facilitate cross-species and cross-treatment
comparisons. Data are structured in a tabular format with metadata for
closure time, gas type, fitting method, plant functional type (PFT),
species, and experimental treatments. This dataset supports reuse in
ecological modeling, meta-analyses on plant-mediated greenhouse gas
fluxes, and studies on climate-ecosystem feedbacks. No legal or ethical
restrictions apply; users are encouraged to cite the related research
