Development of a lightweight, portable, waterproof, and low power stem respiration system for trees [PDF]
MethodsX, 2023 Stem respiration is a quantitatively important, but poorly understood component of ecosystem carbon cycling in terrestrial ecosystems. However, a dynamic stem gas exchange system for quantifying real-time stem carbon dioxide (CO2) efflux (Es) is not ...

Mortality correlates with tree functional traits across a wood density gradient in the Central Amazon [PDF]
Frontiers in Plant ScienceIntroductionUnderstanding the mechanisms of tree mortality in tropical ecosystems remains challenging, in part due to the high diversity of tree species and the inherently stochastic nature of mortality.

Canopy gaps and associated losses of biomass – combining UAV imagery and field data in a central Amazon forest [PDF]
Biogeosciences, 2023 Understanding mechanisms of tree mortality and the dynamics of associated canopy gaps is relevant for robust estimates of carbon balance in forests. We combined monthly RGB images acquired from an unoccupied aerial vehicle with field surveys to identify ...

Windthrows increase soil carbon stocks in a central Amazon forest [PDF]
Biogeosciences, 2016 Windthrows change forest structure and species composition in central Amazon forests. However, the effects of widespread tree mortality associated with wind disturbances on soil properties have not yet been described in this vast region.
