Human Domination of Earth's Ecosystems
Human alteration of Earth is substantial and growing. Between one-third and one-half of the land surface has been transformed by human action; the carbon dioxide concentration in the atmosphere has
HUMAN ALTERATION OF THE GLOBAL NITROGEN CYCLE: SOURCES AND CONSEQUENCES
Nitrogen is a key element controlling the species composition, diversity, dynamics, and functioning of many terrestrial, freshwater, and marine ecosystems. Many of the original plant species living
Terrestrial ecosystem production: A process model based on global satellite and surface data
This paper presents a modeling approach aimed at seasonal resolution of global climatic and edaphic controls on patterns of terrestrial ecosystem production and soil microbial respiration. We use
Biological invasions by exotic grasses, the grass/fire cycle, and global change
Biological invasions into wholly new regions are a consequence of a far reaching but underappreciated component of global environmental change, the human-caused breakdown of biogeographic barriers to
Significant Acidification in Major Chinese Croplands
TLDR
A meta-analysis of a regional acidification phenomenon in Chinese arable soils that is largely associated with higher N fertilization and higher crop production is presented, likely to threaten the sustainability of agriculture and affect the biogeochemical cycles of nutrients and also toxic elements in soils.
Consequences of changing biodiversity
TLDR
The large ecological and societal consequences of changing biodiversity should be minimized to preserve options for future solutions to global environmental problems.
Enhanced nitrogen deposition over China
TLDR
The impact of N deposition on Chinese ecosystems includes significantly increased plant foliar N concentrations in natural and semi-natural ecosystems and increased crop N uptake from long-term-unfertilized croplands.
Terrestrial phosphorus limitation: mechanisms, implications, and nitrogen-phosphorus interactions.
TLDR
It is suggested that depletion, soil barriers, and low-P parent material often cause ultimate limitation because they control the ecosystem mass balance of P and cause it to be an ultimate limiting nutrient.
Nitrogen limitation on land and in the sea: How can it occur?
AbstractThe widespread occurrence of nitrogen limitation to net primary production in terrestrial and marine ecosystems is something of a puzzle; it would seem that nitrogen fixers should have a
Nutrient Cycling and Nutrient Use Efficiency

TLDR
The pattern for nitrogen circulation and nitrogen use efficiency in forests has important implications for ecosystem-level properties, including the development of low nitrogen availability in soil.
