Amazon rainforests green-up with sunlight in dry season
[1] Metabolism and phenology of Amazon rainforests significantly influence global dynamics of climate, carbon and water, but remain poorly understood. We analyzed Amazon vegetation phenology at multiple scales with Moderate Resolution Imaging Spectroradiometer (MODIS) satellite measurements from 2000 to 2005. MODIS Enhanced Vegetation Index (EVI, an index of canopy photosynthetic capacity) incr...
متن کاملImpact of Evapotranspiration on Dry Season Climate in the Amazon Forest*
Moisture recycling can be an important source of rainfall over the Amazon forest, but this process relies heavily upon the ability of plants to access soil moisture. Evapotranspiration (ET) in the Amazon is often maintained or even enhanced during the dry season, when net radiation is high. However, ecosystem models often over predict the dry season water stress. The authors removed unrealistic...
متن کاملThe Impact of Atmospheric Aerosol from Biomass Burning on Amazon Dry-season Drought
It is increasingly apparent that the future of the Amazon rainforest is under threat from both climate change and agricultural practices. Here we use a 13-year time series of (A)ATSR derived aerosol optical depth (AOD) measurements to examine the role of aerosols in the interaction between deforestation, biomass burning and drought over the Amazon. The seasonal cycle of AOD shows peaks in Septe...
متن کاملEffects of an accidental dry-season fire on the reproductive phenology of two Neotropical savanna shrubs.
Fire is a recurrent disturbance in savanna vegetation and savanna species are adapted to it. Even so, fire may affect various aspects of plant ecology, including phenology. We studied the effects of a spatially heterogeneous fire on the reproductive phenology of two dominant woody plant species, Miconia albicans (Melastomataceae) and Schefflera vinosa (Araliaceae), in a savanna area in South-ea...
