Response of Temperate and Tropical N2-Fixing Trees to Global Environmental Change
Entry ID: USDA0584

[ Update this Record ]

Summary
Abstract: The purpose of this data is to determine the effect of increased carbon dioxide
and associated climate change on temperate and tropical nitrogen-fixing trees
and to determine the impact of environmental change on fixed-nitrogen input
into natural ecosystems.

The approach of this study is to grow nitrogen-fixing tree seedlings under
current and future CO2 concentrations and temperature and to compare the growth
and physiology of the seedlings under these treatments. The change in nitrogen
availability under these experimental regimes is also examined.
