TL;DR: In this article, the role of Saint Joaquim's Fort in the consolidation of the border and of the occupation of the Rio Branco valley, located in the current State of Roraima, is discussed.
Abstract: This article talks about the role of Saint Joaquim’s Fort in the consolidation of the border and of the occupation of the Rio Branco valley, located in the current State of Roraima. It strives to comprehend the process of occupation of the region in the end of the XVIII and XIX centuries, describe the colonial policies of the Portuguese and the Brazilian Empire alike, to discuss questions related to the memory of Saint Joaquim’s Fort, trying to emphasize the subjects who participated in this process. Moreover, there is a discussion about the dispute over Saint Joaquim’s Fort, a question that involves several segments of Roraima’s society, a memory that was appropriated by the so called “pioneer” families because some of them had their origins bound to ex-participants of the fortification and utilized them to justify their possessions and to consolidate their social place.

TL;DR: In this paper, the authors assess the phenology, population structure and the fruit and seed production of native Brazil nut trees in the state of Roraima, and characterizes the extractive communities and extraction system practiced in this region of Amazonia.
Abstract: This paper assesses the phenology, population structure and the fruit and seed production of native Brazil nut trees in the state of Roraima, and characterizes the extractive communities and extraction system practiced in this region of Amazonia. Characterization of the extractive communities and extraction system was done through questionnaires and panel discussions conducted between 2005 and 2010. Analyses of population structure, phenology and fruit and seed production were conducted at sites located in the municipalities of Caracarai and Sao Joao da Baliza, installed between the years 2005-2008. We found that the extraction of Brazil nut makes up a significant part of the income of riverine and indigenous communities but is performed with low levels of social organization, little government support and without any control over the processes that can lead to contamination by aflatoxins. The density and productivity of Brazil nut trees are within the range expected for the Amazon region. We found that Brazil nut tree flowering occurs in the dry season, and lasts five to six months. Dispersal of fruits occurs during four to six months in the rainy season, and peaks between April to June.
