    • Confronting Model Predictions of Carbon Fluxes with Measurements of Amazon Forests Subjected to Experimental Drought 

      Powell, Thomas L; Galbraith, David R.; Christoffersen, Bradley O.; Harper, Anna; Imbuzeiro, Hewlley M. A.; Rowland, Lucy; Almeida, Samuel; Brando, Paulo M.; da Costa, Antonio Carlos Lola; Costa, Marcos Heil; Herrera, Naomi Marcil; Malhi, Yadvinder; Saleska, Scott R.; Sotta, Eleneide; Williams, Mathew; Meir, Patrick; Moorcroft, Paul R (Wiley Blackwell, 2013)
      Considerable uncertainty surrounds the fate of Amazon rainforests in response to climate change. Here, carbon (C) flux predictions of five terrestrial biosphere models (Community Land Model version 3.5 (CLM3.5), Ecosystem ...
    • Evolutionary Trajectories and Biogeochemical Impacts of Marine Eukaryotic Phytoplankton 

      Katz, Miriam E.; Finkel, Zoe V.; Grzebyk, Daniel; Knoll, Andrew; Falkowski, Paul G. (Annual Reviews, Inc., 2004)
      The evolutionary succession of marine photoautotrophs began with the origin of photosynthesis in the Archean Eon, perhaps as early as 3.8 billion years ago. Since that time, Earth's atmosphere, continents, and oceans have ...
    • Modeling Analysis of Primary Controls on Net Ecosystem Productivity of Seven Boreal and Temperate Coniferous Forests Across a Continental Transect 

      Yuan, Fengming; Arain, M. Altaf; Barr, Alan G.; Black, T. Andrew; Bourque, Charles P. A.; Coursolle, Carole; Margolis, Hank A.; McCaughey, J. Harry; Wofsy, Steven C. (Blackwell Publishing, 2008)
      Process-based models are effective tools to synthesize and/or extrapolate measured carbon (C) exchanges from individual sites to large scales. In this study, we used a C- and nitrogen (N)-cycle coupled ecosystem model named ...
    • Seasonal fluxes of carbonyl sulfide in a midlatitude forest 

      Commane, Roisin; Meredith, Laura K.; Baker, Ian T.; Berry, Joseph A.; Munger, J. William; Montzka, Stephen A.; Templer, Pamela H.; Juice, Stephanie M.; Zahniser, Mark S.; Wofsy, Steven Charles (Proceedings of the National Academy of Sciences, 2015)
      Carbonyl sulfide (OCS), the most abundant sulfur gas in the atmosphere, has a summer minimum associated with uptake by vegetation and soils, closely correlated with CO2. We report the first direct measurements to our ...
    • Towards Quantifying Uncertainty in Predictions of Amazon 'Dieback' 

      Moorcroft, Paul; Collins, Mat; Harris, Glen R.; Malhi, Yadvinder; Betts, Richard A.; Jones, Chris D.; Cox, Peter M.; Harris, Phil P.; Sitch, Stephen; Booth, Ben B. B.; Mercado, Lina; Fisher, Rosie A.; Huntingford, Chris (The Royal Society, 2008)
      Simulations with the Hadley Centre general circulation model (HadCM3), including carbon cycle model and forced by a 'business-as-usual' emissions scenario, predict a rapid loss of Amazonian rainforest from the middle of ...
    • What is Geobiology? 

      Knoll, Andrew Herbert; Canfield, Donald E.; Konhauser, Kurt O. (John Wiley & Sons, 2012)
