Drought tolerance and implications for vegetation-climate interactions in the Amazon forest
On seasonal and annual timescales, the Amazon forest is resistant to drought, but more severe droughts can have profound effects on ecosystem productivity and tree mortality. The majority of climate models predict decreased rainfall in tropical South America over this century. Until recently, land …

Interactions of Vegetation and Climate: Remote Observations, Earth System Models, and the Amazon Forest
… interactions change across seasons in the Amazon basin. We use observations of solar induced fluorescence from the Orbiting Carbon Observatory 2 (OCO2) to statistically analyze the sensitivity of fluorescence to synoptic variations in temperature and precipitation. In addition to studying …

Wachstumsraten, Wachstumsmuster und Wachstumsstörungen tropischer Bäume: Analyse von Langzeiteffekten und kurzfristigen Störungen mit Hilfe von Jahrringstudien
… data on understanding some aspects of tropical forest dynamics and ecology. In species that produce annual tree rings, tree-ring analysis allows the most precise estimate of these two parameters. The present study assessed the age and radial growth rate of three Hymenaea species inhabiting four …

Microwave Remote Sensing of Saharan Ergs and Amazon Vegetation
… characteristics of the Sahara desert and the Amazon vegetation. Radar and radiometric responses of the Saharan ergs are related to geophysical properties of sand formations and near surface winds. The spatial and temporal variability of the Amazon vegetation is studied using multi-frequency …

Patterns and processes in tropical forests: an analysis of forest structure and function from long-term permanent plots in Venezuela, Northern South America
… with historical and current disturbances affect forest dynamics and creates complex landscape patterns in forest assemblages and structures. Long-term data collected from a wide range of forest conditions provides an excellent opportunity to examine the underlying processes behind these patterns, …

Forests and fisheries in the Brazilian Amazon: Understanding incentives to comply with conservation efforts
… the analysis of specific cases in the Brazilian Amazon. I first analyze the case of smallholder land clearing along the Transamazon and BR-163 highways in the face of Brazilian Forest Code enforcement by the federal government. My hypothesis is that smallholder land clearing paths over time are …
