Denitrification Associated with Periphyton Communities [PDF]
Scrapings of decomposing Cladophora sp. mats (periphyton) covering stream bed rocks produced N 2 O when incubated under N 2 plus 15% C 2 H 2 . Denitrification (N 2 O formation) was enhanced by NO

Ranking stressor impacts on periphyton structure and function with mesocosm experiments and environmental-change forecasts. [PDF]
Streams are being subjected to physical, chemical, and biological stresses stemming from both natural and anthropogenic changes to the planet. In the face of limited time and resources, scientists, resource managers, and policy makers need ways to rank ...
