| Abstract |
- Despite the vital role in carbon (C) sequestration and
nutrient retention, variations and patterns in root C and nitrogen (N)
stoichiometry of the first five root orders across woody plant species
remains unclear.
- We compiled a dataset to explore variations and patterns
of root C and N stoichiometry in the first five orders of 218 woody
plant species.
- Across the five orders, root N concentrations were
greater in deciduous, broadleaf, and arbuscular mycorrhizal species than
in evergreen, coniferous species, and ectomycorrhizal associations
species, respectively. Contrasting trends were found for root C:N
ratios. Most root branch orders showed clear latitudinal and altitudinal
trends in root C and N stoichiometry. There were opposite patterns in N
concentrations between latitude and altitude. Such variations were
mainly driven by plant species, and climatic factors together.
- Our results indicate divergent C and N use strategies
among plant types and convergence and divergence in the patterns of C
and N stoichiometry between latitude and altitude across the first five
root orders. These findings provide important data on the root economics
spectrum and biogeochemical models to improve understanding and
prediction of climate change effects on C and nutrient dynamics in
terrestrial ecosystems.
