This thesis presents the results of the studies of basin Peixe fiver, a member of the upper basin of the Araguaia River, in the state of Goiás between 1970 and 2009, based on an approach in Ecology Landscape, Geography and Botany (Floristic) applied to the theme of fragmentation of vegetation. The overall goal is to identify and to characterize the remnants and their relations with the evolution of land use and soil types in order to provide data for the evaluation of conservation and sustainability. Methodologically, it employs geo technologies, analysis of landscape metrics and floristic composition of representative fragments beyond the analysis of the relation between land use, soil types and spatial distribution of remaining with emphasis on Principal Component Analysis. The results revealed high rates of current deforestation and increasing fragmentation between 1985 and 2009, and risk, threat to biodiversity conservation. Also revealed predominance of the relation between Ultisols and Pastures interpreting it as a result of the intermediaries agricultural potential of these soils for intensive cultivation due to its high fragility associated with the high erodibility, which would burden other forms of much use, and emphasize concentration of the remaining in areas Permanent Preservation (APP) in the pastures, especially Riparian Forest, more continuous and with greater floristic richness. It was concluded that expand in cattle raising in the studied area was strongly influenced by the soil factor, the low potential of cultivation, which could also explain the lower rate of conversion of the Cerrado, caused by the use anthropic when compared to neighboring basins, where better soils and softer dominated reliefs and softer, and finally the remnants fragments are still recoverable due sustainability indicators revealed by their metrics. Keywords: / A ocupação do Bioma Cerrado no Brasil Central se caracteriza pela incorporação crescente de novas áreas ao sistema produtivo, à custa de desmatamento e conversão ao uso agropecuário das suas terras, inclusive com o apoio de sucessivas políticas públicas desde a década de 1930, mas, sobretudo da década de 1970, induzidas pelo Polocentro- Programa de Desenvolvimento do Cerrado, quando esse processo se intensificou, gerando fragmentação e isolamento dos remanescentes das suas diversas fitofisionomias. A presente tese apresenta o resultado dos estudos da bacia hidrográfica do rio dos Peixes, integrante da alta bacia do rio Araguaia, no estado de Goiás, entre 1970 à 2009, com base numa abordagem em Ecologia da Paisagem, Geografia e Botânica (Florística) aplicada ao tema de fragmentação da cobertura vegetal. O objetivo geral é identificar e caracterizar os remanescentes e suas relações com a evolução de uso do solo e os tipos de solos, de modo a fornecer subsídios para a avaliação da sua conservação e sustentabilidade. Metodologicamente, utiliza-se de geotecnologias, análise das métricas da paisagem e da composição florística de fragmentos representativos além da análise da relação entre o uso do solo, os tipos de solos e a distribuição espacial dos remanescentes, com ênfase na Análise dos Componentes Principais. Os resultados revelaram elevada taxa de desmatamento atual e fragmentação crescente entre 1985 à 2009, além de comprometimento de conservação da biodiversidade. Revelaram ainda predominância da relação entre Argissolos e Pastagens interpretando-a como resultante do potencial agrícola intermediário desses solos para cultivos intensivos devido sua fragilidade elevada associada a sua alta erodibilidade, o que oneraria muito outras formas de uso, e enfatizam a concentração dos remanescentes em Áreas de Preservação Permanente (APP) nas áreas de pastagem, sobretudo Mata Ciliar, mais contínua e com maior riqueza florística. Concluiu-se que a expansão pecuária na bacia estudada foi fortemente condicionada pelo fator solo, de baixa aptidão agrícola, o que explicaria também sua menor taxa de conversão do Cerrado ao uso antrópico, quando comparada às bacias vizinhas, onde dominam melhores solos e relevos mais suaves, e, finalmente, que seus fragmentos remanescentes ainda são recuperáveis, devido aos indicadores de sustentabilidade revelados por suas métricas.

The Walling Family of Nineteenth-Century Texas recounts the actions of the first four generations of the John Walling family. Through a heavily quantitative study, the study focuses on the patterns of movement, service, and seizing opportunity demonstrated by the family as they took full advantage of the benefits of frontier expansion in the Old South and particularly Texas. In doing so, it chronicles the role of a relatively unknown family in many of the most defining events of the nineteenth-century Texas experience such as the Texas Revolution, Mexican War, Civil War, Reconstruction, and the Close of the Frontier. Based on extensive research in census, tax, election, land, military, family paper, newspaper, and existing genealogical records; the study documents the contributions of family members to the settlement of more than forty counties while, at the same time, noting its less positive behaviors such as its open hostility to American Indians, and significant slave ownership. This study seeks to extend the work of other quantitative studies that looked at movement and political influence in the Old South, Texas, and specific communities to the microcosm of a single extended family. As a result, it should be of use to those wanting a greater understanding of how events in nineteenth-century Texas shaped, and were shaped by, families outside the political and social elite.
