  • Annual rainfall and seasonality predict pan-tropical patterns of liana density and basal area 
    DeWalt, Saara J.; Schnitzer, Stefan A.; Chave, Jerome; Bongers, Frans; Burnham, Robyn J.; Cai, Zhiquan; Chuyong, George B.; Clark, David B.; Ewango, Corneille E. N.; Gerwing, Jeffrey J.; Gortaire, Esteban; Hart, Terese; Ibarra-Manriquez, Guillermo; Ickes, Kalan; Kenfack, David; Macia, Manuel J.; Makana, Jean-Remy; Martinez-Ramos, Miguel; Mascaro, Joseph; Moses, Sainge; Muller-Landau, Helene C.; Parren, Marc P. E.; Parthasarathy, Narayanaswamy; Perez-Salicrup, Diego; Putz, Francis E.; Romero-Saltos, Hugo; Thomas, Duncan (2010)
    We test the hypotheses proposed by Gentry and Schnitzer that liana density and basal area in tropical forests vary negatively with mean annual precipitation (MAP) and positively with seasonality. Previous studies correlating ...
  • Controls over aboveground forest carbon density on Barro Colorado Island, Panama 
    Mascaro, Joseph; Asner, G. P.; Muller-Landau, Helene C.; van Breugel, Michiel; Hall, Jefferson S.; Dahlin, K. (2011)
    Despite the importance of tropical forests to the global carbon cycle, ecological controls over landscape-level variation in live aboveground carbon density (ACD) in tropical forests are poorly understood. Here, we conducted ...
  • Evaluating uncertainty in mapping forest carbon with airborne LiDAR 
    Mascaro, Joseph; Detto, Matteo; Asner, Gregory P.; Muller-Landau, Helene C. (2011)
    Airborne LiDAR is increasingly used to map carbon stocks in tropical forests, but our understanding of mapping errors is constrained by the spatial resolution (i.e., plot size) used to calibrate LiDAR with field data ...
  • High-fidelity national carbon mapping for resource management and REDD+ 
    Asner, Gregory P.; Mascaro, Joseph; Anderson, Christopher; Knapp, David E.; Martin, Roberta E.; Kennedy-Bowdoin, Ty; van Breugel, Michiel; Davies, Stuart James; Hall, Jefferson S.; Muller-Landau, Helene C.; Potvin, Catherine Jeanne; Sousa, Wayne; Wright, S. Joseph; Bermingham, Eldredge (2013)
  • Hydrological Networks and Associated Topographic Variation as Templates for the Spatial Organization of Tropical Forest Vegetation 
    Detto, Matteo; Muller-Landau, Helene C.; Mascaro, Joseph; Asner, Gregory P. (2013)
  • Increasing Liana Abundance and Basal Area in a Tropical Forest: The Contribution of Long-distance Clonal Colonization 
    Yorke, Suzanne R.; Schnitzer, Stefan A.; Mascaro, Joseph; Letcher, Susan G.; Carson, Walter P. (2013)
    Recent evidence suggests that liana abundance and biomass are increasing in Neotropical forests, representing a major structural change to tropical ecosystems. Explanations for these increases, however, remain largely ...
  • Novel forests maintain ecosystem processes after the decline of native tree species 
    Mascaro, Joseph; Hughes, R. Flint; Schnitzer, Stefan A. (2012)
    The positive relationship between species diversity (richness and evenness) and critical ecosystem functions, such as productivity, carbon storage, and nutrient cycling, is often used to predict the consequences of extinction. ...
  • These are the days of lasers in the jungle 
    Mascaro, Joseph; Asner, Gregory P.; Davies, Stuart James; Dehgan, Alex; Saatchi, Sassan (2014)
    For tropical forest carbon to be commoditized, a consistent, globally verifiable system for reporting and monitoring carbon stocks and emissions must be achieved. We call for a global airborne LiDAR campaign that will ...
  • A universal airborne LiDAR approach for tropical forest carbon mapping 
    Asner, Gregory P.; Mascaro, Joseph; Muller-Landau, Helene C.; Vieilledent, Ghislain; Vaudry, Romuald; Rasamoelina, Maminiaina; Hall, Jefferson S.; van Breugel, Michiel (2012)
    Airborne light detection and ranging (LiDAR) is fast turning the corner from demonstration technology to a key tool for assessing carbon stocks in tropical forests. With its ability to penetrate tropical forest canopies ...
