Texto completoThe dissertation aims to contribute to a broader review effort of what has been commonly identified as hierarchical organisation in the Americas. It is a question of exploring the challenges posed by the supposed eyiguayegui/kadiwéu hierarchy: slaves treated with affection and who are not forced to work; voluntary servants; taxpayers who receive gifts from their masters; captains who do not command; hereditary status that are won or lost by force of character or skills; female warriors; male singers and a social stratification seemingly analogous to that of feudal Europe, but in which even slaves could rise to the rank of nobleman or captain. Starting from this panorama constructed by the specialized literature, lightened by the current reflections of Americanist ethnology, the dissertation exams the data collected by the colonial documentation and the current ethnographies in order to analyze (and to question) the construction of an epistemic regime that reads the relations eyiguayegui/kadiwéu as based on a hierarchy system and on a separation between \"domestic\" and \"political\" domains. A close examination of these data has led to the questioning of various terms used over the centuries in the descriptions of the eyiguayegui/kadiwéu political relations, such as \"slavery\", \"labor\", \"servitude\", \"symbiosis\", \"ownership\" social stratification and the idea of \"hierarchy\" itself. This questioning has led, finally, to the reflection about the construction of the eyiguayegui bodies and, consequently, of what I denominate distinctions or differentiations between eyiguayegui people.

Texto completoLand-use change is a primary driver of biodiversity loss. During recent decades, the tropics and subtropics have witnessed accelerating deforestation rates, resulting in widespread extinctions. Even if further deforestation was to be avoided, species would likely continue to disappear due to delays in their responses to land-use change. The goals of this thesis were to provide a better understanding of the effects of past and contemporary land use on biodiversity in the Argentine Dry Chaco, and to develop approaches that capture the impacts of land-use change on biodiversity before local extinctions occur. The Argentine Dry Chaco provides an excellent scenario for this purpose due to its dynamic land-use history, the high deforestation rates, and its high biodiversity levels. At the community level, I found that species richness of birds and mammals was influenced by past landscape patterns, suggesting time-delayed responses to land-use change and the evidence of an extinction debt. These time-delayed responses were due to habitat fragmentation rather than habitat loss. At the population level, I found that giant anteater occupancy decreased particularly after 2000 when agriculture expanded rapidly. My results further suggested that land-use change had substantial indirect effects on species’ populations. Finally, I assessed the effects of deforestation on collared peccaries at the population and individual level. Peccary occupancy was highest in areas with high woodland cover. Where peccaries were present, physiological stress was negatively correlated with food availability. Overall, this thesis shows that deforestation is driving species to extinction in the Argentine Dry Chaco. While some species may disappear quickly following deforestation, extinctions of others may not be immediate, providing an opportunity to prevent those extinctions. The approaches presented in this thesis help to identify those opportunities in dynamic landscapes such as deforestation frontiers.

Texto completoParallelisms between stories of biblical inspiration and myths that describe the origins of the human beings, their corporal transformations and the differences between diverse types of beings can be found in contemporary narrations of the Toba people (Qom) of the Argentinean Gran Chaco. Events described in the Bible are usually spun with elements of the mythical past of Toba people, therefore generating a biblical reading of the indigenous past and new readings on the human origins, of the differences between beings and of the importance of the body in the constitution of human specificity. This paper examines some of these narrations where myths and Biblical stories are interlaced giving rise to new notions of body and person.

Resumo: As áreas de Chaco em território sulamericano, representam a maior área de floresta seca contínua do continente. No Brasil, estas áreas são encontradas principalmente na porção sudeste do domínio, no estado de Mato Grosso do Sul, região sul-pantaneira. Talvez por serem áreas de pouca cobertura, o seu conhecimento ainda é incipiente. Embora novos projetos tenham sido realizados nestas áreas nos últimos anos, a sua crescente supressão pelas atividades de pecuária extensiva tem sido preocupante. Não há na região qualquer tipo de Unidade de Conservação a fim de preservar o patrimônio genético das espécies que lá ocorrem, muitas das quais têm sua distribuição limitada a esta fitofisionomia. Desta forma, estudos que visem o conhecimento da variabilidade genética ainda existente, principalmente em áreas em processo de degradação são fundamentais para o conhecimento da atual situação das populações existentes, para indicar métodos de conservação, bem como a propor políticas públicas visando a manutenção e conservação do Chaco brasileiro. A fim de efetuar estimativas da diversidade genética, o uso de marcadores moleculares tem sido empregado em diversos estudos de populações nas diversas formações vegetacionais, principalmente no Brasil. Os microssatélites (SSRs), tem se mostrado uma ferramenta versátil e confiável. O presente estudo teve por objetivo efetuar um estudo genético populacional de Prosopis rubriflora e P. ruscifolia em áreas de Chaco brasileiro, com distintos níveis de perturbação antrópica e ainda, avaliar o sistema de reprodução, pelo uso de progênies, em P. rubriflora, com o emprego de microssatélites. Inicialmente foi construída uma biblioteca enriquecida em microssatélites para P. rubriflora e P. ruscifolia, empregando-se DNA genômico extraído de material foliar. Foram obtidos 21 marcadores microssatélites polimórficos, sendo nove deles para P. rubriflora e 12 para P. ruscifolia. Posteriormente, foram amostrados indivíduos de ambas as espécies em 19 áreas remanescentes de Chaco em Mato Grosso do Sul, com diferentes níveis de perturbação. Uma área aparentemente conservada na região foi selecionada para a amostragem das progênies de P. rubriflora em dois anos consecutivos de amostragem. A genotipagem foi efetuada por meio de sequenciador automático ABI 3500 Genetic Analyzers. Os resultados da genotipagem foram utilizados para estimar os parâmetros de diversidade genética, tendo eles sido similares em ambos os táxons, como o He = 0,59 em P. rubriflora e He = 0,60 em P. ruscifolia. Foi detectado efeito de gargalo populacional em todos os remanescentes de P. rubriflora e na maioria de P. ruscifolia. Constatou-se ausência de estruturação genética intrapopulacional em P. rubriflora (FIS = 0,042), bem como estruturação genética interpopulações moderada (FST = 0,057) resultante da nítida separação dos remanescentes de Nioaque e Porto Murtinho. Em P. ruscifolia foi encontrado, indícios de estruturação ao nível intrapopulacional, e baixa estruturação interpopulacional (FIS = 0,138 e FST = 0,042). Identificou-se que P. rubriflora apresenta um sistema de reprodução preferencialmente alógamo e deve apresentar mecanismos bastante efetivos para evitar a endogamia, principalmente, devido a maioria dos polinizadores apresentarem baixa dispersão entre as plantas. As duas espécies deste estudo apresentam respostas relativamente distintas às perturbações ambientais nas áreas chaquenhas, sendo que P. ruscifolia parece ser mais vulnerável às degradações em comparação a P. rubriflora. Assim, espera-se que estes dados sirvam de apoio para medidas conservacionistas para as áreas chaquenhas, que são extremamente diminutas em território brasileiro
Abstract: Chaquenian areas in Brazil have a short range distribution and are found mainly in Mato Grosso do Sul county, South Pantanal region, and it comprehends a narrow coverage, is possibly the main reason for the poor knowledge of these areas. While new projects were conducted in these areas in recent years, the suppression of the remnant areas due to cattle breeding activities has been a source of concern, because there is no conservation units to protect the genetic heritage of the native species those counties, where the Chaco¿s remnants occur. In this scenario, studies aiming to increase the knowledge of the current genetic diversity, specially where environmental disturbing processes take place, provides important data to understand the current situation of the remaining populations. Moreover, with this study it is possible to indicate conservation measures and public politics aiming at the maintenance and conservation Brazilian chaquenian areas. In order to estimate the genetic diversity, molecular markers have been used in several population studies from different vegetation formations, mainly in Brazil. Microsatellites (SSRs) is one of the most popular molecular markers, considerated a versatile and reliable tool. This study aimed a population genetics study with Prosopis rubriflora and P. ruscifolia in Brazilian chaquenian areas with distinct disturbing levels and conducts a mating system study with P. rubriflora. Initially, we built an enriched library of microsatellites from P. rubriflora and P. ruscifolia using leaf tissue to extract genomic material, which allowed to obtain 21 polymorphic markers, where, nine markers were developed for P. rubriflora and 12 for P. ruscifolia. Then, we sampled individuals of both species in 19 remnant areas of Chaco in Mato Grosso do Sul¿s county, with different disturbance levels. We selected one apparently conserved remnant for sampling progenies of P. rubriflora, with two consecutive years of sampling. The genotyping procedure was performed using an automatic sequencer ABI 3500 Genetic Analyzers. Through the genotyped data, we estimated genetic diversity parameters and observed results He = 0.59 for P. rubriflora and He = 0.60 for P. ruscifolia. We were able to detect a bottleneck effect in all remnants of P. rubriflora and also, in most of P. ruscifolia remnant areas. We reported a not significant intrapopulation genetic structure in P. rubriflora (FIS = 0.042) although with moderated structure between-populations (FST= 0.057) was observed, with the separation of two distinct populations for the studied remnants. A low, but significant genetic structure within and a low genetic structure between populations (FIS = 0.138 and FST = 0.042), is reported for P. ruscifolia in this study. The analysis showed an outcrossing mating system for P. rubriflora suggesting a very effective mechanism to prevent inbreeding, even with the pollinators of predominently low dispersion. The species in this study presents a relatively distinct response to environmental disturbance caused by anthropic factors in chaquenhas areas, P. ruscifolia seems to be more vulnerable to degradations as compared to P. rubriflora. Despite this scenario, we hope that these available data will aid into conservation measures for chaquenhas areas, which is distributed in a narrow range in Brazilian¿s territory

Texto completoObjectifs: Les principaux buts de la thèse sont (1) de déterminer l’influence de l’aridité et des conditions édaphiques sur la distribution et la structure des assemblages de fourmis terricoles du sol en forêts tropicales sèches, (2) mettre en évidence les mécanismes qui facilitent la coexistence des espèces de fourmis à l’échelle locale, (3) déterminer si à l’échelle régionale les fourmis et les plantes répondent de façon similaire aux conditions du milieu.
Méthode: Onze localités ont été échantillonnées le long d’un transect régional long de 400km. Au niveau de chaque localité, trois transects élémentaires longs de 200m et séparés les uns des autres par 200m ont été effectués. La myrmécofaune a été échantillonnée à l’aide de 20 pièges à fosse et de 20 Winkler par transect élémentaire. La végétation de chaque site a été caractérisée sur base de l’abondance de 45 espèces d’arbres ou d’arbustes caractéristiques de la flore chaquéenne. Les propriétés physico-chimiques du sol ont également été mesurées. A fine échelle, l’organisation spatio-temporelle d’un assemblage a été étudié dans une localité de référence.
Résultats: Au total, plus de 50.000 spécimens correspondant à 206 espèces de fourmis ont été collectés avec en moyenne (± SD) 62 ± 10 espèces par localité. Pour un même effort d’échantillonnage, le nombre d’espèces de fourmis récoltées à l’aide des pièges à fosse augmente avec l’aridité et une tendance inverse est observée pour les Winkler. Puisque les Winkler peuvent entraîner une sévère sous-estimation de la diversité des fourmis d’un habitat, seules les données des pièges à fosse sont utilisées pour la suite des analyses.

Texto completoDeixis is prior to naming in the history of language (s), nouns are substitutes to deictics, not the other way round. It is therefore wrong to speak about "pronouns". This is confirmed by morphophonological, syntactical, diaglottic (borrowing), ontogenetic and phylogenetic criteria. Deicticity is one among several properties of language which do not reflect nor depend on sheer reason: iconicity, phonosymbolism, multiplicity of encoding, contradictability, fixity, tabouicity. Diachronic evolutivity is also definitory of language. For all these reasons the concept of "natural language" is tautological. Language reflects in its very structure the nature both spiritual and affective of its speakers, who are not only rational beings

Texto completoOf Arawak origin, the ethnic group identified as the Chané indigenous group in the Amerindian literature, settled on the eastern slopes of the Andes before the Conquest of the Occidental region or Paraguayan Chaco took place. There, this group engaged in complex inter-ethnic relationships with other Guarani-speaking ethnic groups, Chaco natives, and thereafter, as the colonization process consolidated, with several Creole social agents: landowners, foremen of sugar plantations, the military, and missionaries. Supported by ethnographic and ethno-historical documents, the author suggests that the open, flexible, malleable and integrating organization of Chané shamanism was marked by these multiple historical interactions, thereby becoming an ideal symbolic language to reflect the problems arising from situations of intercultural contact.

The Gray Area The Interpretation of Chen Chao-Liang’s Printmaking Printmaking differs from other sorts of surface painting in that it starts with another medium to express its own concept and emotion. Other sorts of painting, on the other hand, enable viewers to feel stronger and more direct interaction between the artist and the work of art. This thesis serves the following four purposes: 1. because of regarding the time space and the memory reciprocity, pauses in-depth spirit face, unifies the correlation theories foundation to make uniform, so as to explains the self-creation idea the basic construction.; 2. it clarifies my creation style and direction by structuring and modifying my creation system and texture; 3. it arranges and analyzes personal works, completing the current printmaking creation; 4. it explores the direction of future research through reflecting upon and criticizing current works. In short, this thesis is composed of the basis of theory research, the body of personal works of art, and the reflection on the spirit of creation through discourse. It expresses my own artistic insight in both subjective and objective ways, discusses the relationship between printmaking creation and personal works of art, and analyzes the form and meaning of my personal works. In the fourth chapter, the interaction between idea and form will be discussed, which helps clarify and build my personal creation style; this is done by examining my works in a chronicle order and connecting real creation experiences and literal descriptions of the works. The discourse of this thesis, in the space and time of memory, through the subjectivity of personal creation ideas and the objectivity of forms of art, starts from my own artistic concept, moves across the form of art and meaning of creation, and positions the future direction of personal creation. In the process of research, I came to a new form of printmaking presentation through the combination of different materials. With the use of a second Shade version and basic version, the printmaking presentation becomes more flexible, and the picture size more extensive. The discovery of new materials has brought me new insights into creation, larger space for imagination, and a whole new creation experience. Keywords: Dream, Memory, Time, Space, Printmaking, Intaglio
