Effect of woody debris on fluvial system nitrogen
General Background:
Woody debris in fluvial systems may stimulate denitrification, the microbial conversion of nitrate-N to N2O and N2 which needs anaerobic conditions and carbon or another electron donor.
We are exploring this topic through two projects:
- Wood block mesocosms to assess denitrification hotspots in RI and PA streams
- Sediment core incubations to assess denitrification hotspots in RI beaver ponds

Talk will be presented at the 2012 AWRA Summer Specialty Conference, June 2012.
