    • 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 ...

    • Phylogeny, diversification patterns and historical biogeography of euglossine orchid bees (Hymenoptera: Apidae) 

      RAMÍREZ, SANTIAGO R.; ROUBIK, DAVID W.; SKOV, CHARLOTTE; Pierce, Naomi E. (Wiley-Blackwell, 2010)
      The orchid bees constitute a clade of prominent insect pollinators distributed throughout the Neotropical region. Males of all species collect fragrances from natural sources, including flowers, decaying vegetation and ...

    • Resolving systematic errors in estimates of net ecosystem exchange of CO2 and ecosystem respiration in a tropical forest biome 

      Hammond-Pyle, Elizabeth; Munger, J. William; Saleska, Scott R.; Daube, Bruce C.; Restrepo-Coupe, Natalia; Wofsy, Steven; de Camargo, Plinio B.; Hutyra, Lucy R. (Elsevier, 2008)
      The controls on uptake and release of CO<sub>2</sub> by tropical rainforests, and the responses to a changing climate, are major uncertainties in global climate change models. Eddy-covariance measurements potentially provide ...

    • Seasonal carbon dynamics and water fluxes in an Amazon rainforest 

      Kim, Yeonjoo; Knox, Ryan G.; Longo, Marcos; Medvigy, David; Hutyra, Lucy; Pyle, Elizabeth; Wofsy, Steven Charles; Bras, Rafael L.; Moorcroft, Paul R (Wiley-Blackwell, 2012)
      Satellite-based observations indicate that seasonal patterns in canopy greenness and productivity in the Amazon are negatively correlated with precipitation, with increased greenness occurring during the dry months. Flux ...
