  • Nitrous oxide emission from denitrification in stream and river networks 

    Beaulieu, Jake J.; Tank, Jennifer L.; Hamilton, Stephen K.; Wollheim, Wilfred M.; Hall, Robert O.; Burgin, A.J. (National Academy of Sciences, 2011-11-11)
    Nitrous oxide (N2O) is a potent greenhouse gas that contributes to climate change and stratospheric ozone destruction. Anthropogenic nitrogen (N) loading to river networks is a potentially important source of N2O via ...
  • Have we overemphasized the role of denitrification in aquatic ecosystems? A review of nitrate removal pathways 

    Burgin, A.J.; Hamilton, Stephen K. (Ecological Society of America, 2007-03-01)
    The removal of nitrogen (N) in aquatic ecosystems is of great interest because excessive nitrate in groundwater and surface water is a growing problem. High nitrate loading degrades water quality and is linked to eutrophication ...
  • Nitrate removal in stream ecosystems measured by 15N addition experiments: Denitrification 

    Mullholland, Patrick J.; Hall, Robert O.; Sobota, Daniel J.; Dodds, Walter K.; Findlay, Stuart E. G.; Grimm, Nancy B.; Hamilton, Stephen K.; McDowell, William H.; O'Brien, Jonathan M.; Burgin, A.J. (Association for the Sciences of Limnology and Oceanography, 2009-05-12)
    We measured denitrification rates using a field 15NO3− tracer-addition approach in a large, cross-site study of nitrate uptake in reference, agricultural, and suburban-urban streams. We measured denitrification rates in ...
  • Nitrate removal in stream ecosystems measured by 15N addition experiments: Total uptake 

    Hall, Robert O.; Tank, Jennifer L.; Sobota, Daniel J.; Mullholland, Patrick J.; O'Brien, Jonathan M.; Dodds, Walter K.; Webster, Jackson R.; Valett, H. Maurice; Burgin, A.J. (Association for the Sciences of Limnology and Oceanography, 2009-05-12)
    We measured uptake length of 15NO3− in 72 streams in eight regions across the United States and Puerto Rico to develop quantitative predictive models on controls of NO3− uptake length. As part of the Lotic Intersite Nitrogen ...
  • Sediment nitrate manipulation using porewater equilibrators reveals potential for N and S coupling in freshwaters 

    Payne, E.K.; Burgin, A.J.; Hamilton, Stephen K. (Inter Research, 2009-02-24)
    Anthropogenic nitrogen (N) loading to agricultural and populated landscapes has resulted in elevated nitrate (NO3–) concentrations in ground water, streams and rivers, ultimately causing problems in coastal marine environments ...
  • Restarting the conversation: challenges at the interface between ecology and society 

    Groffman, Peter M.; Stylinski, Cathlyn; Nisbet, Matthew C.; Duarte, Carlos M.; Jordan, Rebecca; Burgin, A.J.; Previtali, M. Andrea; Coloso, James (Ecological Society of America, 2010-08-01)
    The exchange of information between researchers, resource managers, decision makers, and the general public has long been recognized as a critical need in environmental science. We examine the challenges in using ecological ...
  • Beyond carbon and nitrogen: how the microbial energy economy couples elemental cycles in diverse ecosystems 

    Burgin, A.J.; Yang, Wendy H.; Hamilton, Stephen K.; Silver, Whendee L. (Ecological Society of America, 2011-02-01)
    Microbial metabolism couples elemental reactions, driving biogeochemical cycles. Assimilatory coupling of elemental cycles, such as the carbon (C), nitrogen (N), and phosphorus cycles, occurs when these elements are ...
  • Soil O2 controls denitrification rates and N2O yield in a riparian wetland 

    Burgin, A.J.; Groffman, Peter M. (American Geophysical Union, 2012-02-01)
    [1] Wetland soil oxygen (O2) is rarely measured, which limits our understanding of a key regulator of nitrogen loss through denitrification. We asked: (1) How does soil [O2] vary in riparian wetlands? (2) How does this ...
  • The under-ice microbiome of seasonally frozen lakes 

    Bertilsson, Stefan; Burgin, A.J.; Carey, Caylen C.; Fey, Samuel B.; Grossart, Hans-Peter; Grubisic, Lorena M.; Jones, Ian D.; Kirillin, Georgiy; Lennon, Jay T.; Shade, Ashley; Smyth, Robyn L. (Association for the Sciences of Limnology and Oceanography, 2013-10-21)
    Compared to the well-studied open water of the “growing” season, under-ice conditions in lakes are characterized by low and rather constant temperature, slow water movements, limited light availability, and reduced exchange ...
  • Iron clad wetlands: Soil iron-sulfur buffering determines coastal wetland response to salt water incursion 

    Schoepfer, Valerie A.; Bernhardt, Emily S.; Burgin, A.J. (American Geophysical Union, 2014-10-25)
    Coastal freshwater wetland chemistry is rapidly changing due to increased frequency of salt water incursion, a consequence of global change. Seasonal salt water incursion introduces sulfate, which microbially reduces to ...
  • The Lotic Intersite Nitrogen Experiments: an example of successful ecological research collaboration 

    Jarecke; Dodds, W.K.; Webster, J.R.; Crenshaw, C.L.; Helton, A.M.; O'Brien, Jonathan M.; Martí, E.; Tank, J.L.; Burgin, A.J. (University of Chicago Press, 2016-05-06)

  • Using an Analytic Hierarchy Process Approach to Prioritize Public Policies Addressing Family Farming in Brazil 

    Petrini, M. A.; Rocha, J.; Brown, J. Christopher; Bispo, R. (Elsevier, 2016-02-01)
    In Brazil, some see intensive, large-scale production of sugarcane-based ethanol, based on a model of capital and land concentration, as a threat to the survival of family farming. Family farmers are increasingly under ...
