Regional Unequal Development: The Case of The Amazon Region, 1880-1960
The purpose of this dissertation is to analyze the development and underdevelopment of the Amazon Region in the period 1880-1960 through a historical perspective.

Estimating evapotranspiration from the Amazon Basin using the atmospheric water balance
The spatio-temporal patterns of evapotranspiration (ET) in the Amazon basin are still poorly understood. Field studies in the Amazonian forest have shown that at some sites, deep roots allow trees to sustain elevated transpiration during several months of minimal rainfall, whereas at others, trees …

Air-breathing and movement ecology of Arapaima sp. in the Amazon
The annual hydrological cycle of floodplains supports fishes that are uniquely adapted to optimize resources throughout the year. Such adaptations to changing environments include air-breathing for seasonally hypoxic waters and directed movements to best utilize habitats as they become available. …

Ecology, Growth, and Migration of Pseudoplatystoma fasciatum in the Amazon Basin
… one-third of all freshwater species occur in the Neotropics, with an estimated 4,475 species within 71 families. Catfishes of the Order Siluriformes include 39 families with 498 accepted genera and 4,123 species. More specifically, members of the Family Pimelodidae, the long-whiskered …

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 …

Trees and people : an anthropology of British campaigners for the Amazon Rainforest
This thesis presents an ethnography of British campaigners and campaigns for the Brazilian Amazon rainforest in the 1990s. It is the result of over two and a half years investigation amongst campaigners in environmental, social and human rights organisations in the UK. My approach combines …

Remote Sensing of Fire, Flooding, and White Sand Ecosystems in the Amazon
<p>Human and natural disturbance affect the Amazon basin at several spatial and temporal scales. In this thesis, I used satellite-detected hot pixels to examine patterns of human-caused disturbance and protected areas in the Brazilian Amazon from 1996-2006. Deforestation fires, as measured by hot …

The impact of edge-effects on aerial insectivorous bat assemblages in the Amazon
Edge effects, the abiotic and biotic changes associated with habitat boundaries, are amongst the most important factors determining a species’ distribution in human-modified landscapes. Bats are the second most diverse mammalian order, however many species are not targeted in studies on …

Forest policy enforcement at the Amazon frontier : the case of Mato Grosso, Brazil
… für eine erhöhte Durchsetzung der Waldgesetze in Amazonien darstellt, wobei seine tatsächliche Wirksamkeit durch eine Reihe polit-ökonomischer und institutioneller Faktoren beeinflusst wird.

Patterns of shallow clouds and rainfall over the Amazon : climatic impacts of deforestation
… to a lesser extent, cold cloud patterns over the Amazon. Through complex interactions, the results reported in this thesis may have important implications for the local ecosystem dynamics of the Amazon, for the geomorphology of the Amazon river basin, for the flow regimes of the Amazon river, …

Local and landscape scale effects of fragmentation on aerial insectivorous bats in the Amazon
Deforestation is the main driver of the biodiversity crisis. Resulting landscapes are left fragmented with isolated remnant forest patches embedded in a human-modified matrix which has the propensity to regenerate into successional forest. The Biological Dynamics of Forest Fragments Project (BDFFP) …

Interactions of Vegetation and Climate: Remote Observations, Earth System Models, and the Amazon Forest
The natural composition of terrestrial ecosystems can be shaped by climate to take advantage of local environmental conditions. Ecosystem functioning, e.g. interaction between photosynthesis and temperature, can also acclimate to different climatological states. The combination of these two factors …

Isotopic constraints on sources and cycling of riverine dissolved inorganic carbon in the Amazon Basin
… of riverine biogeochemical functioning. Amazonian and humid tropical rivers represent a large, neglected source of CO2 to the atmosphere. Carbon isotopes are invaluable tools for examining sources and cycling of inorganic carbon. However, 14C-DIC has never been analyzed in Amazonia, while …

The Amazon in antiquity and on television : deployments of a figure within gender (re)negotiations
Throughout history, the figure of the Amazon has captured the human imagination. In this study, I argue that the popularity of the Amazon is in large part due to her importance as a site of the continuous process of gender negotiation. After drawing upon the work of feminists such as Simone de …

A Geocritical Approach to Coloniality and Aesthetics: Mapping the Spatial Narratives of the Amazon Basin
<p>Coloniality, or the living legacies and practices of the 500 years of European colonization, has produced racial, political, and cultural hierarchies around the colonial difference dividing East from West, center from periphery, civilization from the Global South. This dissertation examines a …

Intensification of agriculture and livestock based on low carbon technologies in the Amazon and Atlantic Forest
The Amazon and the Atlantic Forest are Brazilian biomes that have undergone intense land use and cover changes, marked by the loss of native forest and the expansion of agriculture and livestock. These are areas with potential use for intensification based on low-carbon technologies, but this …
