Patrick J. Mulholland,Patrick J. Mulholland,Ashley M. Helton,Geoffrey C. Poole,Robert O. Hall,Stephen K. Hamilton,Bruce J. Peterson,Jennifer L. Tank,Linda R. Ashkenas,Lee W. Cooper,Clifford N. Dahm,Walter K. Dodds,Stuart E. G. Findlay,Stanley V. Gregory,Nancy B. Grimm,Sherri L. Johnson,William H. McDowell,Judy L. Meyer,H. Maurice Valett,Jackson R. Webster,Clay P. Arango,Jake J.

TL;DR: It is demonstrated that excess nitrate in streams elicits a disproportionate increase in the fraction of nitrate that is exported to receiving waters and reduces the relative role of small versus large streams as nitrate sinks.
Journal ArticleDOI
Nitrous oxide emission from denitrification in stream and river networks
Jake J. Beaulieu,Jennifer L. Tank,Stephen K. Hamilton,Wilfred M. Wollheim,Robert O. Hall,Patrick J. Mulholland,Patrick J. Mulholland,Bruce J. Peterson,Linda R. Ashkenas,Lee W. Cooper,Clifford N. Dahm,Walter K. Dodds,Nancy B. Grimm,Sherri L. Johnson,William H. McDowell,Geoffrey C. Poole,H. Maurice Valett,Clay P. Arango,Melody J. Bernot,Amy J. Burgin,Chelsea L. Crenshaw,Ashley M. Helton,Laura T. Johnson,Jonathan M. O'Brien,Jody D. Potter,Richard W. Sheibley,Richard W. Sheibley,Daniel J. Sobota,Suzanne M. Thomas +28 more
TL;DR: It is found that stream denitrification produces N2O at rates that increase with stream water nitrate (NO3−) concentrations, but that <1% of denitrified N is converted to N1O, and it is suggested that increased stream NO3− loading stimulatesDenitrification and concomitant N2o production, but does not increase the N2 O yield.
Journal ArticleDOI
Inter‐biome comparison of factors controlling stream metabolism
Patrick J. Mulholland,Christy Susan Fellows,Jennifer L. Tank,Nancy B. Grimm,Jackson R. Webster,Stephen K. Hamilton,Eugènia Martí,Linda R. Ashkenas,William B. Bowden,Walter K. Dodds,William H. McDowell,Michael J. Paul,Bruce J. Peterson +12 more
TL;DR: In this article, the authors studied whole-ecosystem metabolism in eight streams from several biomes in North America to identify controls on the rate of stream metabolism over a large geographic range.
Journal ArticleDOI
Inter-regional comparison of land-use effects on stream metabolism
Melody J. Bernot,Daniel J. Sobota,Daniel J. Sobota,Robert O. Hall,Patrick J. Mulholland,Walter K. Dodds,Jackson R. Webster,Jennifer L. Tank,Linda R. Ashkenas,Lee W. Cooper,Clifford N. Dahm,Stanley V.

Thomas,Kym Wilson +34 more
TL;DR: In this article, the influence of land use on stream metabolism across geographic regions is unknown, and there is limited understanding of how land use may alter variability in ecosystem metabolism across regions.
Journal ArticleDOI
Stream Ecosystem Recovery Following a Catastrophic Debris Flow
TL;DR: Study of recovery processes for 3 yr in Quartz Creek, a third-order stream catastrophically impacted by a February 1986 debris flow, found high irradiance levels and reduced grazing by macroinvertebrates contributed to rapid accrual of benthic algae in the disturbed reach, which formed the bioenergetic basis for ecosystem recovery.
