Collaborative Research: Does competition for nitrogen between autotrophs and heterotrophs control carbon fluxes in the western coastal Arctic?
This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).
Scientists on this collaboration will investigate the microbial controls on the productivity of a coastal Arctic ecosystem by focusing on the competition between autotrophs and heterotrophs for nitrogen (N). In the winter and summer waters near Barrow, Alaska, supplemented with complementary international research opportunities, the PIs will measure in situ concentrations of key microbial and biogeochemical constituents, relevant uptake activities, and expression of key N cycling genes to address two hypotheses:
This collaborative research involves grants 0910252 (Yager, UGA, Lead) 0909647 (Frischer, Skidaway); and 0909839 (Bronk, VIMS). The researchers will study the near-shore marine food web, specifically the nitrogen cycle and how it is partitioned between microbial autotrophs and heterotrophs.
