    NASA's Global Ecosystem Dynamics Investigation (GEDI) is collecting spaceborne full waveform lidar data with a primary science goal of producing accurate estimates of forest aboveground biomass density (AGBD). This paper ...
  • Adult mortality in a low-density tree population using high-resolution remote sensing 
    Kellner, James R.; Hubbell, Stephen P. (2017)
  • Density-dependent adult recruitment in a low-density tropical tree 
    Kellner, James R.; Hubbell, Stephen P. (2018)
    The Janzen-Connell hypothesis is a well-known explanation for why tropical forests have large numbers of tree species. A fundamental prediction of the hypothesis is that the probability of adult recruitment is less in ...

    Aim Mapping tree species richness across the tropics is of great interest for effective conservation and biodiversity management. In this study, we evaluated the potential of full-waveform lidar data for mapping tree species ...
  • Impact of a tropical forest blowdown on aboveground carbon balance 
    Cushman, K. C.; Burley, John T.; Imbach, Benedikt; Saatchi, Sassan S.; Silva, Carlos E.; Vargas, Orlando; Zgraggen, Carlo; Kellner, James R. (2021)
    Field measurements demonstrate a carbon sink in the Amazon and Congo basins, but the cause of this sink is uncertain. One possibility is that forest landscapes are experiencing transient recovery from previous disturbance. ...
  • Integrating physiological threshold experiments with climate modeling to project mangrove species' range expansion 
    Cavanaugh, Kyle C.; Parker, John D.; Cook-Patton, Susan; Feller, Ilka C.; Park, Williams, A.; Kellner, James R. (2015)
    Predictions of climate-related shifts in species ranges have largely been based on correlative models. Due to limitations of these models, there is a need for more integration of experimental approaches when studying impacts ...
  • Operational Tree Species Mapping in a Diverse Tropical Forest with Airborne Imaging Spectroscopy 
    Baldeck, Claire A.; Asner, Gregory P.; Martin, Robin E.; Anderson, Christopher B.; Knapp, David E.; Kellner, James R.; Wright, S. Joseph (2015)
    Remote identification and mapping of canopy tree species can contribute valuable information towards our understanding of ecosystem biodiversity and function over large spatial scales. However, the extreme challenges posed ...

  • Pervasive canopy dynamics produce short-term stability in a tropical rain forest landscape 
    Kellner, James R.; Clark, David B.; Hubbell, Stephen P. (2009)
