Carbon Dynamics

 
         CD-Q3 - What are the relative contributions of fluxes from natural and disturbed ecosystems to the net Amaz˘nia-wide flux?
 

Nutrient Dynamics and Surface Water Chemistry

 
         ND-Q4 - How do changes in land use and climate alter the stocks, processes and fluxes of dissolved and particulate organic matter, nutrients, and trace gases from the uplands across the riparian zones and floodplains and down the channels of river corridors?
         ND-Q4a - How will the composition and quantity of nutrients and organic matter entering and being processed within streams be altered under different land-use change scenarios?
         ND-Q4b - Are there unique signatures that can be traced downstream?
         ND-Q4c - To what extent do intact riparian zones buffer streams against changes due to anthropogenic activities in surrounding uplands?
         ND-Q5 - What is the importance of periodically "wet" environments (from moist soils to standing and flowing waters) for the land and atmospheric balances of nutrients, carbon dioxide, trace gases, and water and energy on multiple scales?
 

Trace Gas and Aerosol Flux

 
         TG-Q1 - How are fluxes of trace gases and aerosols between ecosystems (both upland and wetland) and the atmosphere of Amaz˘nia affected by land cover and land use change?
