General Background:
• Small, first and second order streams have been associated with substantial denitrification and nitrogen uptake.
• Previous studies have shown that streams vary markedly in their ability to cycle nitrogen, yet streams that have high removal rates may be important nitrogen sinks across the landscape.
What are we currently doing?
We are employing the isotope
tracer method to assess the denitrification potential in first
and second order New England streams. We hypothesize that streams
with increased leaf and woody debris will have higher potential
for denitrification.
