| É fundamental para os Modelos de Vegetação Dinâmica Global (DVGM na sigla em inglês) representar corretamente o ciclo diário, as variações sazonais e interanuais das trocas de massa e energia entre o ecossistema e a atmosfera, a hidrologia do solo, a fenologia das plantas e a evolução do estoque de carbono do ecossistema. Este estudo dedica-se a validação e calibração do DVGM IBIS (Integrated Biosphere Simulator) para um ecossistema de floresta tropical úmida de terra firme, localizada na Reserva Biológica do Cuieiras do INPA. Foram utilizados nove anos de dados meteorológicos da torre de fluxo K34, como também dados de diâmetro de árvores, medidas de sonda de nêutrons, de liteira fina e foi realizado um ajuste nos parâmetros físicos do solo do modelo. Os... |

| Canopy and aerodynamic conductances (gC and gA) are two of the key land surface biophysical variables that control the land surface response of land surface schemes in climate models. Their representation is crucial for predicting transpiration (?ET) and evaporation (?EE) flux components of the terrestrial latent heat flux (?E), which has important implications for global climate change and water resource management. By physical integration of radiometric surface temperature (TR) into an integrated framework of the Penman?Monteith and Shuttleworth?Wallace models, we present a novel approach to directly quantify the canopy-scale biophysical controls on ?ET and ?EE over multiple plant functional types (PFTs) in the Amazon Basin. Combining data from six LBA... |

| Canopy and aerodynamic conductances (gC and gA) are two of the key land surface biophysical variables that control the land surface response of land surface schemes in climate models. Their representation is crucial for predicting transpiration (λET) and evaporation (λEE) flux components of the terrestrial latent heat flux (λE), which has important implications for global climate change and water resource management. By physical integration of radiometric surface temperature (TR) into an integrated framework of the Penman?Monteith and Shuttleworth?Wallace models, we present a novel approach to directly quantify the canopy-scale biophysical controls on λET and λEE over multiple plant functional types (PFTs) in... |

| The Amazon rain forest sustains the world's highest tree diversity, but it remains unclear why some clades of trees are hyperdiverse, whereas others are not. Using dated phylogenies, estimates of current species richness and trait and demographic data from a large network of forest plots, we show that fast demographic traits ? short turnover times ? are associated with high diversification rates across 51 clades of canopy trees. This relationship is robust to assuming that diversification rates are either constant or decline over time, and occurs in a wide range of Neotropical tree lineages. This finding reveals the crucial role of intrinsic, ecological variation among clades for understanding the origin of the remarkable diversity of Amazonian trees and... |

| An important current problem in micrometeorology is the characterization of turbulence in the roughness sublayer (RSL), where most of the measurements above tall forests are made. There, scalar turbulent fluctuations display significant departures from the predictions of Monin?Obukhov similarity theory (MOST). In this work, we analyze turbulence data of virtual temperature, carbon dioxide, and water vapor in the RSL above an Amazonian forest (with a canopy height of 40 m), measured at 39.4 and 81.6 m above the ground under unstable conditions. We found that dimensionless statistics related to the rate of dissipation of turbulence kinetic energy (TKE) and the scalar variance display significant departures from MOST as expected, whereas... |

| Abstract: Forestry in the Cerrado Biome have the potential to act as carbon sink and storage and can be used as climate change mitigation option through compensatory planting. The Cerrado occupies about 23% of the national territory, presenting varied physiognomies. The Cerrado sensu stricto (herbaceous layer with different densities of tree and shrubs) is the predominant physiognomic type with total extent of about 41.8 million hectares. The Cerrado biome may play a significant role on global carbon balance due to carbon storage and fixation. However, vast areas of Cerrado have been degraded as a result of extensive and frequent fire mainly related with cattle ranching. Planted forests in Cerrado are predominant comprised of eucalyptus, which are... |

| The Amazon Basin plays key roles in the carbon and water cycles, climate change, atmospheric chemistry, and biodiversity. It already has been changed significantly by human activities, and more pervasive change is expected to occur in the next decades. It is therefore essential to establish long-term measurement sites that provide a baseline record of present-day climatic, biogeochemical, and atmospheric conditions and that will be operated over coming decades to monitor change in the Amazon region as human perturbations increase in the future. The Amazon Tall Tower Observatory (ATTO) has been set up in a pristine rain forest region in the central Amazon Basin, about 150 km northeast of the city of Manaus. An ecological survey including a biodiversity... |
