Nitrogen oxide emissions after nitrogen additions in tropical forests
Article Abstract:
Phosphorus-limited forest loses more nitrogen oxides than nitrogen-limited forest, according to research based on measurements of soil nitrous oxide and nitric oxide emissions before and after nitrogen additions in two forests situated at the ends of a clearly defined substrate-age gradient in the Hawaiian Islands. The nitrogen-limited site showed very low fluxes of nitrogen oxides. The fluxes did not rise significantly after the first nitrogen addition. It is possible that nitrogen oxide emissions from phosphorus-limited tropical ecosystems are particularly sensitive to anthropogenic nitrogen inputs.

Marine microorganisms and global nutrient cycles
Article Abstract:
Marine microorganisms are a major component of global nutrient cycles due to their capacity for rapid growth. Four exciting aspects of marine microbial ecology that are receiving great attention and might prove to be crucial to a revised understanding of marine and global nutrient cycling are highlighted.

Agricultural runoff fuels large phytoplankton blooms in vulnerable areas of the ocean
Article Abstract:
A study demonstrates that nitrogen-deficient areas of the tropical and subtropical oceans are acutely vulnerable to nitrogen pollution. The findings highlight the present and future vulnerability of these ecosystems of agricultural runoff.
