The Rondonian-San Ignacio Province in the SW Amazonian Craton: An overview

The Rondonian-San Ignacio Province (1.56-1.30 Ga) is a composite orogen created through successive accretion of arcs, ocean basin closure and final oblique microcontinent-continent collision. The effects of the collision are well preserved mostly in the Paragua Terrane (Bolivia and Mato Grosso regions) and in the Alto Guapore Belt and the Rio Negro-Juruena Province (Rondonia region), considering that the province was affected by later collision-related deformation and metamorphism during the Sunsas Orogeny (1.25-1.00 Ga). The Rondonian-San Ignacio Province comprises: (1) the Jauru Terrane (1.78-1.42 Ga) that hosts Paleoproterozoic basement (1.78-1.72 Ga), and the Cachoeirinha (1.56-1.52 Ga) and the Santa Helena (1.48-1.42 Ga) accretionary orogens, both developed in an Andean-type magmatic arc; (2) the Paragua Terrane (1.74-1.32 Ga) that hosts pre-San Ignacio units (>1640 Ma: Chiquitania Gneiss Complex, San Ignacio Schist Group and Lomas Manechis Granulitic Complex) and the Pensamiento Granitoid Complex (1.37-1.34 Ga) developed in an Andean-type magmatic arc; (3) the Rio Alegre Terrane (1.51-1.38 Ga) that includes units generated in a mid-ocean ridge and an intra-oceanic magmatic arc environments; and (4) the Alto Guapore Belt (<1.42-1.34 Ga) that hosts units developed in passive marginal basin and intra-oceanic arc settings. The collisional stage (1.34-1.32 Ga) is characterized by deformation, high-grade metamorphism, and partial melting during the metamorphic peak, which affected primarily the Chiquitania Gneiss Complex and Lomas Manechis Granulitic Complex in the Paragua Terrane, and the Colorado Complex and the Nova Mamore Metamorphic Suite in the Alto Guapore Belt. The Paragua Block is here considered as a crustal fragment probably displaced from its Rio Negro-Juruena crustal counterpart between 1.50 and 1.40 Ga. This period is characterized by extensive A-type and intra-plate granite magmatism represented by the Rio Crespo Intrusive Suite (ca. 1.50 Ga), Santo Antonio Intrusive Suite (1.40-1.36 Ga), and the Teotonio Intrusive Suite (1.38 Ga). Magmatism of these types also occur at the end of the Rondonian-San Ignacio Orogeny, and are represented by the Alto Candeias Intrusive Suite (1.34-1.36 Ga), and the Sao Lourenco-Caripunas Intrusive Suite (1.31-1.30 Ga). The cratonization of the province occurred between 1.30 and 1.25 Ga. (C) 2009 Elsevier Ltd. All rights reserved.

Growth of Channel Catfish, Ictalurus punctatus, in Southern Brazil

Despite successful introduction of channel catfish into Brazil in 1980, no studies have been conducted to assess the performance of channel catfish, Ictalurus punctatus, farming in southern Brazil. Fingerlings (27.0 ± 2.2 g) were stocked in sixteen 16-m2 tanks with cement walls and earthen bottoms. Four stocking densities were used: 0.5, 0.75, 1.0, and 1.25 fish/m2. Fish were fed a diet containing 32% protein according to a feeding chart for 257 days (from April to December). Water temperature ranged from 16.4°C to 30°C during the study. Final average weight (727.1 ± 70.6 g) was significantly higher (P < 0.05) for fish raised at 0.5 fish/m2. Food conversion ratio (FCR) was significantly higher (P < 0.05) for fish stocked at 1.25 fish/ m2. Survival averaged 95.4%, and no significant differences (P > 0.05) were found among treatments. There was no significant difference (P > 0.05) in tank production among the densities of 0.75, 1.0, and 1.25 fish/m2, but they were higher (P < 0.05) than the density of 0.5 fish/ m2. These results demonstrate the viability of channel catfish growth in southern Brazil.

Birds of Santa Teresa, Espírito Santo, Brazil: Do humans add or subtract species?

In uplands and lowlands of Santa Teresa, central Espírito Santo State, Brazil, 405 bird species were confirmed by field, museum, and literature studies. Of these, 16 seem to have disappeared, while 67 other species seem to have been lost from the lowlands (where no large biological reserves exist). Due to a suggestion that human areas add species to beta-diversity, we verified that up to 79 species now present have perhaps invaded with human activity (and 10 others are likely to invade), a total similar to that for lost species. However, lost species are often rare and invading species often widespread, resulting in exchange of Picassos for Coca-Cola bottles. Furthermore, gains exceed losses only when large biological reserves are present, as in the uplands (Nova Lombardia, Santa Lucia Reserves, each with over 250 species). Small or irregular reserves usually lose well over half their species, and these are only partly replaced by the invaders, resulting in net losses of up to half the local avifaunas. If one lists only 31 probable invaders, rather than a possible 79, things are even worse; net losses occur even in the entire township and near reserves, reaching over 200 species around lowland private reserves. Future productive development of human areas can eliminate or maltreat many invading species, too. While approving taxes on improductive use of land, as it leaves other areas free, we suggest that many current local uses, such as for coffee, are luxury production and could, be taxed.

Efeitos de níveis de cobertura do solo sobre a produtividade e crescimento do feijoeiro irrigado, em sistema de plantio direto

The objective of this research was to study the effects of five different treatments of grass (Brachiaria decumbens) straw mulch on common beans (Phaseolus vulgaris L.): 0% (0 t.ha-1), 25% (2,25 t.ha-1), 50% (4,5 t.ha-1), 75% (6,75 t. ha-1) and 100% (9,0 t/ha) designed by randomized blocks, with four replicates. The irrigation was applied when minimum soil water potential were reached about - 30kPa. The water management based on tensiometers and soil water characteristic curve. A microsprinkler irrigation system was used. The experiment was set up at the Experimental Station of Embrapa Rice and Bean (Empresa Brasileira de Pesquisa Agropecuária Arroz e Feijão) at Santo Antonio de Goiás, Brazil, in a Dark - Red Latosol soil. The results showed: the bean yield and his components were not affected by treatments, except grain number/pod,. The mulch increased the water use efficiency and, consequently, decreased the number of irrigations when the mulch reached more than 50% straw mulch. The treatment with 100% of mulching presented the largest leaf area index and dry matter accumulation was not affected by mulching.

Avaliação de política ambiental e sustentabilidade: Estudo de caso do município de Santo André - SP

The management of the São Paulo Metropolitan Area has as one of the challenges to bring a sustainable solution for land use in watershed protection areas, aiming at regional water resources protection. This paper has the objective to contribute to the discussion about Sustainable Development Strategy Assessment, from an analisys with focus at the environmental policies of the Santo André City - SP Brazil, in the context of water resources protection. For this, the proposal is to verify, based on the Bellagio Principles, the use of systemic approach, transparency, participatory process and social engagement in its policy formulation and implementation process. It was observed coherence within the policies, programmes and actions analysed, nevertheless, gaps were identified, which, within a strategic approach, means weakness for the construction of the local sustainability, as the lack of a consolidated sustainability indicators system.

Cursos de geologia: expansão, interiorização e consolidação do ensino de geologia no brasil

A short time after the creation of the first Geology courses in Brazil (in 1957 with the pioneers in the University of São Paulo and in the Federal Universities of Ouro Preto, Pernambuco and Rio Grande do Sul, and then in the following year in the Federal Universities of Bahia and Rio de Janeiro), there arose other initiatives that spread almost twenty Geology courses throughout Brazil. In addition to expanding the Geology teaching in the South, Southeast and Northeast regions, these initiatives succeeded in allowing access to geological education for the population in the North and Central-west of Brazil. In the 1960s, the courses in the Federal University of Para in Belém (1964), University of Brasilia (1965) and São Paulo State University in Rio Claro (1969) were implanted. In the following decade, the courses in the Federal Rural University of Rio de Janeiro in Seropédica (1970), the Federal University of Ceará in Fortaleza (1970), the University of Rio dos Sinos in São Leopoldo (1973), the Federal University of Paraná in Curitiba (1973), the Federal University of Minas Gerais in Belo Horizonte (1973), the Federal University of Amazonas in Manaus (1976), the Federal University of Mato Grosso in Cuiabá (1976), the Federal University of Rio Grande do Norte in Natal (1976), and the State University of Rio de Janeiro in Rio de Janeiro (1977) were all created. At the close of the twentieth century, the course was implanted in the State University of Campinas (1998). Now, at the beginning of the twenty-first century, new Geology courses are being implanted, accentuating the movement inland of Geology teaching in Brazil. The Federal University of Pará began a new course in its campus in Marabá in the south-east of Pará and the Federal University of Bahia implanted a new course in its campus in Barreiras in the west of Bahia. Finally, the Federal Universities of Sergipe, Espírito Santo and Roraima commenced Geology courses in Aracaju, Alegre and Boa Vista, respectively. This chapter will present the synthesis of the Geology courses which, over the last decades of the twentieth century, contributed to the expansion of Geology teaching in the country, taking it to every region and giving opportunities to a large number of Brazilian citizens to realize their dreams and tread the paths of their professional vocation.
