Unchecked climate change will cause severe drying of the Amazon forest
extreme drought Amazon rain forests Unchecked climate change
2021/8/4
Amazon rain forests could be at far higher risk of extreme drought than previously thought, according to new research.
Improving the ISBACC land surface model simulation of water and carbon fluxes and stocks over the Amazon forest
water and carbon fl uxes surface model simulation
2015/8/6
We evaluate the ISBACC (Interaction Soil Biosphere Atmosphere Carbon Cycle) land surface model
(LSM) over the Amazon forest, and propose a revised parameterization of photosynthesis, including new so...
Predicting the response of the Amazon rainforest to persistent drought conditions under current and future climates: a major challenge for global land surface models
major challenge global land surface models
2014/12/19
While a majority of global climate models project drier and longer dry seasons over the Amazon under higher CO2 levels, large uncertainties surround the response of vegetation to persistent droughts i...
Fine root dynamics for forests on contrasting soils in the Colombian Amazon
Fine root dynamics forests contrasting soils the Colombian Amazon
2010/1/21
It has been hypothesized that as soil fertility increases, the amount of carbon allocated to below-ground production (fine roots) should decrease. To evaluate this hypothesis, we measured the standing...

A simulation model based on satellite observations of monthly vegetation cover from the Moderate Resolution Imaging Spectroradiometer (MODIS) was used to estimate monthly carbon fluxes in terrestrial ...
Branch xylem density variations across the Amazon Basin
Branch xylem density variations Amazon Basin
2010/1/19
Xylem density is a physical property of wood that varies between individuals, species and environments. It reflects the physiological strategies of trees that lead to growth, survival and reproduction...
Estimates of fire emissions from an active deforestation region in the southern Amazon based on satellite data and biogeochemical modelling
fire emissions active deforestation region Amazon satellite data biogeochemical modelling
2010/1/19
Tropical deforestation contributes to the build-up of atmospheric carbon dioxide in the atmosphere. Within the deforestation process, fire is frequently used to eliminate biomass in preparation for ag...
