Background Knowledge of biological and climatic controls in terrestrial nitrogen (N) cycling
within and across ecosystems is central to understanding global patterns of key ecosystem …

We compiled new and published data on the natural abundance N isotope composition
(δ15N values) of soil and plant organic matter from around the world. Across a broad range …

Advances in technology have made extensive surveys of 15 N natural abundances in
terrestrial ecosystems feasible at the regional and even global scale within the last decade …

The nitrogen (N) cycle involves a set of N compounds transformed by plants and microbes.
Some of these N compounds, such as nitrous oxide (N 2 O) or nitrate (NO 3−), are …

Ratios of nitrogen (N) isotopes in leaves could elucidate underlying patterns of N cycling
across ecological gradients. To better understand global‐scale patterns of N cycling, we …

To determine the dominant processes controlling nitrogen (N) dynamics in soils and
increase insights into soil N cycling from nitrogen isotope (δ 15 N) data, patterns of 15 N …

Nitrogen cycling in forest soils has been intensively studied for many years because
nitrogen is often the limiting nutrient for forest growth. Complex interactions between soil …

Quantifying global patterns of terrestrial nitrogen (N) cycling is central to predicting future
patterns of primary productivity, carbon sequestration, nutrient fluxes to aquatic systems and …

Nitrogen (N) influences local biological processes, ecosystem productivity, the composition
of the atmospheric-climate system, and the human endeavour as a whole. Here we use …

Isotope pool dilution studies are increasingly reported in the soils and ecology literature as a
means of measuring gross rates of nitrogen (N) mineralization, nitrification, and inorganic N …
