Повний текст джерелаThe humid mountains of Northeast Brazil, locally named Brejos de altitude, form islands of humidity where evergreen forest (mata atlântica) contrasts with the semi-arid conditions of the surrounding plain (Sertão). Despite the ecological, cultural and socio-economic importance of such humid mountains across a wide semi- arid area (‘Polígono das secas’), the high diversity of their physical environment has so far been poorly characterised. This study outlines the relevance of a pedogeomorphological approach to the understanding and management of landscape systems. Here the Baturité massif (Ceará) showcases the methodology used in this study, which involves i) a detailed field survey based on a combined description of landforms, weathering mantles and soils ; ii) the analytical characterization of soils and weathering materials based on a wide range of complementary pedological, sedimentological and geochemical laboratory methods ; and iii) the processing and spatial analysis of field and laboratory data in a GIS, with an aim to develop a modernised method of pedogeomorphic mapping applicable to the study of other mountains. The main results are presented in the form of an original inventory of pedogeomorphic landscape units for the Baturité massif and its piedmont. These results are placed within a more global scientific debate centred on the evolution of tropical landscapes, and the hypotheses are tested against geographic comparisons in Brazil and on other continents (Africa, India). The potential for agricultural development of the land systems of the humid mountains and their surrounding semi- arid plains are discussed in the light of the original results of this study

Повний текст джерелаIn this work we carry out a terminological study and give a terminographic treatment to the vocabulary of the conceptual field "protection of the environnement of Brasil", more specifically, from Brazil's protected areas. We have therefore elaborated a specialised encyclopedic vocabulary the functions of which are as follows : a synthesis of the most important information on the linguistic level and of knowledge of the terminology in the chosen domain ; b. Conveying the information which could help relations between organised sectors of brasilian and french societies interested by the conservaation of nature in Brazil. Therefore we propose a model of macrostructure, macrostructure microstructure and of returning system adapted to the type of directory. We have also organised the terminology into a unified system of terms and notions. In this thesis we propose some definition models adapted each time to the type of vocabulary and to the domain studied; we observe the principal theoreticl problems of the translation into french of the vocabulary of Brazil's protected areas. From a terminological (lexicological) point of view, we analyse the morpho-syntaxic and lexico-semantic of the terminology that is dealt with; we identify the principal process of creation and of lexical renewal into the protected areas of Brazil and finally we analyse the principal relations of established meaning between terminological unities studied

Повний текст джерелаThe fact that we have been attributing increasing importance to scientific research on the tropical rain forest, specially on the amazon, means that we should study these activities that became strategie. The objective of this work is to contribute to our understanding of those scientific practices, their dynamics and organization at the amazon region. Our focus is on the construction of knowledge and the build up of a research infrastructure and for doing that we use two series of interviews (in Brazil and France), one case study and examination of the scientific literature. This inquiry allow us to advancie the thesis that those actions of one researche actors posses one unique dynamics because each step forward reveal the conformation of the object of study that is renewes accordind to place, time and scale of observation. The combination of specific factors generated form different situations that does not maintaint the relionship among them. A dynamic view of the context and environment where research is conducted take us to the conclusion them the word amazon acquires various meanings, and that the scientific knowledge produced on/from this region results in a multitude of cognitive practices where the concrete realizations do not let themselves harmonize easily

Повний текст джерелаFree-Iiving marine nematodes are the most important taxon in shallow-water sediments. In tropical environments nematodes colonize preferentially the calcareous sand of Thalassia testudinum seagrass beds and mud sediments of mangrove swamp. The results presente demonstrate by SEM analysis and by molecular hybridization FISH/CARD-FISH, the presence of extracellular bacteria belonging to the y proteobacteria and localized on the body surface of eight species of nematodes belonging to the genera Eubostrichus, Robbea and Stilbonema (Stilbonematinae family). The analysis conducted in Raman microspectrometry have revealed the presence of elemental sulfur S8 in the bacterial coat associate of nematodes and more specifically to the sulfur granules translucent observed by MET in the periplasmic space of bacteria. The Raman microspectrometry has proven a powerful tool for the detection of sulfo-oxidizing symbioses and more generally for the detection of thiotrophic metabolism among mangrove meiofauna organisms. The study of the mangrove nematofauna has revealed a f1uctuating dynamic of the population, either monospecific or diverse, colonizing a heterogeneous and reduced sulfur (1mM to 10mM) sediment. Nematodes of mangroves are dominated by deposit feeders and sorne genera such as Terschellingia, Daptonema and Gomphionema constitute the basic nematofauna in this environment with more specific nematodes such as Eubostrichus, Croconema and Pseudochromadora
