Progressive Nitrogen Limitation of Ecosystem Responses to Rising Atmospheric Carbon Dioxide
Abstract A highly controversial issue in global biogeochemistry is the regulation of terrestrial carbon (C) sequestration by soil nitrogen (N) availability. This controversy translates into great…

Responses of terrestrial ecosystems to temperature and precipitation change: a meta‐analysis of experimental manipulation
Global mean temperature is predicted to increase by 2–7 °C and precipitation to change across the globe by the end of this century. To quantify climate effects on ecosystem processes, a number of…

A global synthesis reveals biodiversity loss as a major driver of ecosystem change
TLDR
The analyses clearly show that the ecosystem consequences of local species loss are as quantitatively significant as the direct effects of several global change stressors that have mobilized major international concern and remediation efforts.

Nitrogen and Climate Change
Models project that land ecosystems may be able take up a considerable proportion of the carbon dioxide released by human activities, thereby counteracting the anthropogenic emissions. In their…

Altered soil microbial community at elevated CO2 leads to loss of soil carbon
TLDR
It is shown how elevated CO2, by altering soil microbial communities, can cause a potential carbon sink to become a carbon source.

The fate of carbon in grasslands under carbon dioxide enrichment
The concentration of carbon dioxide (CO2) in the Earth's atmosphere is rising rapidly, with the potential to alter many ecosystem processes. Elevated CO2 often stimulates photosynthesis, creating the…

Measuring terrestrial subsidies to aquatic food webs using stable isotopes of hydrogen.
TLDR
The consistent differences between leaves and algae in deltaD among these four watersheds, along with the intermediate values in higher trophic levels, indicate that natural abundance hydrogen isotope signatures are a powerful tool for partitioning energy flow in aquatic ecosystems.

Carbon-Nitrogen Interactions in Terrestrial Ecosystems in Response to Rising Atmospheric Carbon Dioxide
AbstractInteractions involving carbon (C) and nitrogen (N) likely modulate terrestrial ecosystem responses to elevated atmospheric carbon dioxide (CO2) levels at scales from the leaf to the globe and…

Global change, nitrification, and denitrification: A review
We reviewed responses of nitrification, denitrification, and soil N2O efflux to elevated CO2, N availability, and temperature, based on published experimental results. We used meta‐analysis to…
