Globally Mapping the Nitrogen Stable Isotope Ratios of Terrestrial Vegetation From 1984 to 2022

open access: yesEarth's Future, Volume 13, Issue 12, December 2025.
Abstract Nitrogen cycles control the structure, function, and composition of ecosystems globally. Despite their importance, our understanding of long‐term changes in global nitrogen cycles remains limited. The foliar nitrogen stable isotope ratio (δ15N) serves as a valuable metric for assessing changes in nitrogen cycling and potentially in plant ...
