13. Abundância e distribuição de Aeglidae (Crustacea: Anomura) em função do uso da terra na bacia hidrográfica do Rio Jacutinga, Rio Grande do Sul, Brasil
This study investigated the influence of land use and occupation on the density and distribution of aeglids in the hydrographic basin of the Jacutinga river (northern state of Rio Grande do Sul, Brazil). Sampling was carried out during the summer and winter of 2004, at 12 sites distributed in river spring, agriculture, grazing, and urban areas. Animals were

14. Análise por vetor de mudanças para a avaliação multitemporal e multissensores da cobertura das terras do cerrado / Change vector analysis for multitemporal and multisensor assessment of Cerrado land cover
The main objective was to study the multitemporal expansion of agriculture for 33 years using there different satellites/sensors, by applying Principal Components Analysis techniques in order to generate the components of brightness and greenness for each dataset. The use of these components for the Change Vector Analysis can thus provide information on the

16. Cartographic and aerophotogrametric techniques in the study of erosion: high basin of the river Araquá, municipality of Sao Pedro and Charqueada / SP / Técnicas cartográficas e aerotogramétricas no estudo da erosão: alta bacia do Ribeirão Araguá - São Pedro e Charqueada / SP
This study aimed to make an inventory of the forms of linear erosion in the high basin of the river Araquá, municipality of San Pedro and Charqueada / SP, based on cartographic and aerophotogrametric techniques in analog and digital environment. The survey was conducted in 2 different scales of approach: 1:50.000 (semi-detailed) and 1:15.000 (detailed). In

17. TERRITORIALIDADES RURAIS EM JÚLIO DE CASTILHOS RS: DA PECUÁRIA EXTENSIVA À AGRICULTURA FAMILIAR. / RURAL TERRITORIALITIES IN JÚLIO DE CASTILHOS RS: FROM EXTENSIVE CATTLE RANCHING TO FAMILY FARM.
Júlio de Castilhos City has undergone significant transformations in its rural space last decades. It has happened because of large lands retraction and extensive cattle ranching in favour of Soya new agriculture. The partial fragmentation of cattle breeding and its reorganization has occurred in three main forms: land rent, land sell and expropriation when

19. Soil quality of cultivated and native pastures systems in the Nhecolandia sub-region, South Pantanal Wetlands. / Qualidade do solo em sistemas de pastagens cultivada e nativa na sub-regiÃo da NhecolÃndia, Pantanal Sul Mato-Grossense
The Pantanal is one of the planetâs largest continuous wetlands areas and where fauna and flora of outstanding beauty and abundance develops. Favored by the richness of natural resources, beef cattle raising, conducted in extensive raising systems, constitutes the chief economic activity. However, the search for yield increases and greater competitivity of

20. Caracterização física, estrutural e da diversidade floristica de fragmentos florestais na alta bacia do Rio Araguaia
The upper Araguaia river basin region has been transformed by rapid and intensive human occupation processes that began in the 1970s, and now the landscape is highly fragmented. Remnant forests are surrounded by cotton and soybean plantations and pasture. They continue to be subjected to degradation and little is known about their ecological integrity. The o

22. Environmental impacts and nutrient recycling on pastures grazed by cattle
Grasslands are being replaced by urbanization and more profitable agricultural activities around the world. Producers may be faced with land constraints and need to consider intensification of the remaining grasslands as a means of maintaining overall production on a decreasing land resource. However, intensification of the grazing system is usually associat

23. Aspects of natural history and conservation of Pseudalopex vetulus (Lund, 1842) (Carnivora: Canidae) / Aspectos da história natural e conservação de Pseudalopex vetulus (Lund, 1842) (Carnivora: Canidae)
The influence of human activities on wild species has been increasing in a rate without precedents. As to Cerrado, the second biggest Brazilian vegetal formation, around a half of its original ground cover has already been changed into grazing lands, annual crops and other sort of usages; such fact represents a threatening to the survival of species that liv

24. Aplicação de lodo de esgotos municipais no solo : ensaios de respirometria para avaliar a estabilidade do lodo
The final fate of the sewage sludge, trom treatment plants, is a serious problem alI over the world today. The recycling of this material through its incorporation on agricultural and grazing soils is an important alternative. The dry sludge has 60-70 % of organics and some percent of nutrients. The remaining material, after its residual degradation, is a go
