Multiple global change factors alter the scaling of nitrogen to phosphorus in alpine plants

The stoichiometry and allometry of nitrogen (N) and phosphorus (P) reflect plant nutrient absorption and dynamic allocation. They can be regulated by global change factors (e.g., climate warming, nitrogen enrichment, and altered precipitation). Yet, how multiple global change factors act interactively to influence the stoichiometric characteristics of N and P and their scaling relationships in different plant organs remains poorly understood. In a field experiment with treatments of nitrogen addition (Nadd), warming (W), and reduced precipitation (Pr) in an alpine meadow, we examined how global change factors interact to alter N and P stoichiometric characteristics of leaves and seeds. An allometry model (i.e., N = βPα) was employed to detect changes in the scaling of plant N to P under different treatments. Our results showed that nitrogen addition significantly increased leaf N concentration (+44.0 %), seed N concentration (+16.9 %) and leaf N : P ratios (+27.8 %) under ambient temper..., , # Multiple global change factors alter the scaling of nitrogen to phosphorus in alpine plants
