Abstract:

This study compares the soils, floristic composition, phytosociological structure and history of seven Brazilian savannas in the Amazon basin: those at Alter do Chao, Amapa, Roraima and SE Humaita are islands in rain forest; and those at Chapada dos Parecis, Redencao, and Carolina are on the periphery (northern border) of the central Brazilian savannas (the so-called 'cerrado'). A total of 26 transects were sampled by the PCQ method (for trees with dbh greater than or equal to 5 cm) and additional tree species were recorded by 'wide patrolling'. A total of 101 species were recorded from the tr

Abstract:

En este artículo argumentamos que este tipo de agricultura para el caso del Valle del río Apurímac y Ene (VRAE), localizado en la región sur de selva alta peruana, seguía en funcionamiento durante los años del 2001 y 2004. En ese período han ocurrido cambios en esta modalidad de uso del suelo, pero éstos han sido realmente menores. Para ilustrar estos cambios, aprovechamos un estudio realizado hace 14 años utilizándolo como testimonio histórico. En este trabajo describimos las estrategias productivas de los colonos y su impacto en la deforestación. Nuestro argumento central es que la co

Abstract:

Conservation of the world's biodiversity is increasingly viewed as a development problem, requiring the alleviation of poverty together with the promotion of alternative livelihoods in resource-reliant communities. To be successful, such efforts must recognize the underlying logic of resource-users' livelihood choices. This study uses the activity of aquarium fish extraction in the Peruvian Amazon as a case study through which to examine the role that physical and non-physical assets (primarily knowledge) might play in determining households' participation patterns.

Abstract:

This thesis investigates the resistance of actors of civil society against perceived militarism, by means of a qualitative case study. As the title suggests, the establishment of a “Cyber Valley” in Tübingen, has not only been met with approval by local citizens. This thesis examines a protest movement against the Cyber Valley – a cooperative research project for technological advancements in Artificial Intelligence and Machine Learning. The research reveals that this protest movement was not reliant on a firm organizational structure but was led by an open alliance of individuals, called the

Abstract:

Physical erosion can mobilise particulate organic carbon (POC) from vegetation and soil, representing an export of primary productivity from ecosystems, and a lateral transfer of carbon recently-derived from the atmosphere. These carbon transfers are thought to be enhanced in mountain forests where erosion rates are high. However, the rates and controls on POC transfer remain poorly constrained, as does the impact of POC export on carbon cycling at regional and global scales. This thesis takes an interdisciplinary approach to address this issue, using remote sensing, river geochemistry, river

Abstract:

This thesis is an ethnographic study of the pursuit of kametsa asaiki (‘the good life’) in an Ashaninka village by the Bajo Urubamba River (Peruvian Amazonia). My study centres on Ashaninka social organization in a context made difficult by the wake of the Peruvian Internal War, the activities of extractive industries, and a series of despotic decrees that have been passed by the Peruvian government. This is all framed by a change in their social organization from living in small, separated family-based settlements to one of living in villages. This shift presents them with great problems when

Le Río Beni se caractérise en effet par un style à méandres à la migration très rapide, tandis que le Napo développe un style anastomosé, individualisant des îles végétalisées et

Abstract:

Austrian playwright Jovita Epp's German language novel Amado mío, which takes place in post-WWII Argentina, is a modern adaptation of the traditional colonial novel. As such, the romances between the female main character, an Argentine of German descent, and her two love interests, an Argentine of Spanish descent (Criollo), and an Austrian Argentine, reflect the hopes and fears of persons and/or cultures caught up in the imperialist dreams of their nation. In the wake of WWII, Argentina becomes a space in which European(-descended) settlers can look back at Europe's "barbarism," questioning

Abstract:

The composition and distribution of fish assemblages was examined in a floodplain lake system in the Amazon basin. Quantitative samples were collected during the 1992-1993 flooding season at Marchantaria Island, Solimoes River. A total of 25,819 specimens representing 8 orders, 30 families, 101 genera and 139 species of fish were collected. Analysis of species richness distribution among 7 vegetation strata showed that vegetated sites had higher species richness than unvegetated sites. Stands of Paspalum repens had the most diverse fish fauna. Canonical correspondence analysis (CCA) was used t

Abstract:

Geography and the Environment<br>Studies of the Amazon drainage network have primarily focused on the Western Basin and the Amazon Cone, but they have neglected the integration between these areas. Data presents a time gap in the Amazon’s development and the forces responsible for the organization of the drainage network are poorly understood. A key element towards gaining an improved awareness of the Amazon is the Eastern Amazon River Valley. The focus of this study is an 80,000 km² portion of this area. An integrated method is adopted that combines terrain information derived from a digital
