    Full Text Available Campos rupestres are rare and endangered ecosystems that accommodate a species-rich flora with a high degree of endemism. Here, we make available a dataset from phytosociological surveys carried out in the Itacolomi State Park, Minas Gerais, southeastern Brazil. All species in a total of 30 plots of 10 x 10 m from two study sites were sampled. Their cardinality, a combination of cover and abundance, was estimated. Altogether, we registered occurrences from 161 different taxa from 114 genera and 47 families. The families with the most species were Poaceae and Asteraceae, followed by Cyperaceae. Abiotic descriptions, including soil properties such as type, acidity, nutrient or aluminum availability, cation exchange capacity, and saturation of bases, as well as the percentage of rocky outcrops and the mean inclination for each plot, are given. This dataset provides unique insights into the campo rupestre vegetation, its specific environment and the distribution of its diversity.

    Full Text Available The objective of this work was to evaluate qualitative and quantitative leaf anatomical traits of Palicourea rigida Kunth. (Rubiaceae species occurring in the Brazilian Cerrado and Campo Rupestre ecosystems. Anatomical analysis was performed in fresh or fixed leaves processed with usual plant microtechnique. Leaves showed uniseriate epidermis in petiole and leaf blade which contains uniseriate nonglandular tricomes (tector type occurring only over the vascular bundles. Likewise, paracytic stomata were found only in abaxial side of the leaf surface. The mesophyll contains uniseriate palisade parenchyma and multiseriate spongy parenchyma (nine layers which showed cells with different morphology and size. Crystal idoblasts of different types were observed in both the petiole and leaf blade. Collateral vascular bundles were found both in the petiole and leaf blade. Leaf venation type was pinnate, campylodromous or brochydodromous. The micromorphometric analysis showed significant differences from plants of different environments for all leaf characteristics and Cerrado plants showed higher means for all evaluated traits. Therefore, the influence of environments may had modulated morphological responses in P. rigida, since no difference was found in the type or distribution of leaf tissues in Cerrado or Campo Rupestre.

    The Brazilian "campo rupestre" vegetation shows high light heterogeneity, characteristic which is often disregarded in ecophysiological studies due the difficult of obtaining accurate measurements in a complex environment. The aim of the present study it was to describe how much heterogeneous is the light distribution in this environment, as well as tried to define classes in relation to the photosynthetically active radiation (PAR) for 30 rupicolous individuals of Bulbophyllum involutum. The individuals were marked and previously classified in light classes visually predetermined ("full sun", "partially shaded" and "shaded"). Once defined these classes, principal component analysis, cluster and dispersal analyses using direct and indirect PAR measures were performed to characterize the environment as well as to validate the inclusion of the individuals in each class. The use of multivariate analysis increased the accuracy of predetermined classes of light, and some individuals from "shaded" and "partially shaded" classes needed to be regrouped. After individuals' reclassification, amplitude of PAR variance was reduced in each class, enhancing homogeneity. Ours results show the possibility to evaluate light environment conditions more precisely in "campo rupestre" vegetation using multivariate analysis, allowing the increase in accuracy of this parameter for ecophysiological researches.

    Full Text Available ABSTRACTWe studied the effects of seed storage on germination and dormancy alleviation in three species of Fabaceae endemic to campo rupestrein southeastern Brazil. Fresh seeds of Collaea cipoensis, Mimosa maguirei and Mimosa foliolosawere set to germinate and germination of seeds after four, five and 13 years of storage was tested. Seed viability was maintained for all species after the full storage period. Seed storage significantly increased germination percentage and decreased germination time for C. cipoensisand M. foliolosa, suggesting the alleviation of physical dormancy with storage. However, we did not find evidence of dormancy alleviation in M. maguirei since stored seeds showed a decrease in germination in comparison to that of fresh seeds. Our data indicate species-specific storage-mediated dormancy alleviation, which will have important implications for restoration of campo rupestre.

    Full Text Available Among the compounds stored by plants, several functions are assigned to fructans, such as source of energy and protection against drought and extreme temperatures. In the present study we analyzed the anatomy and distribution of fructans in vegetative organs of Dimerostemma vestitum (Asteraceae, an endemic species from the Brazilian campos rupestres. D. vestitum has amphistomatic and pubescent leaves, with both glandular and non-glandular trichomes. In the basal aerial stem the medulla has two types of parenchyma, which differ from the apical portion. The xylopodium has mixed anatomical origin. Interestingly, although inulin-type fructans with high degree of polymerization were found in all analyzed organs except the leaves, the highest amount and maximum degree of polymerization were detected in the xylopodium. Inulin sphero-crystals were visualized under polarized light in the medulla and in the vascular tissues mainly in the central region of the xylopodium, which has abundant xylem parenchyma. Secretory structures accumulating several compounds but not inulin were identified within all the vegetative organs. The presence of these compounds, in addition to inulin, might be related to the strategies of plants to survive adverse conditions in a semi-arid region, affected seasonally by water restriction and frequently by fire.

    Hymenoptera such as bees and social wasps are regular floral visitors in "campos rupestres" vegetation. A community of bees and social wasps was studied during floral visitation in an area of "campos rupestres", at Chapada Diamantina, BA, Brazil, from September 2001 to April 2002. The community was described in relation to diversity, evenness, and dominance rank, considering the individuals abundance (H' = 2.14/ J' = 0.55) and biomass (H' = 2.34/ J' = 0.60). Thirty nine bee (588 individuals/ 15.742 g) and 11 social wasp species (52 individuals/ 2.156 g) were collected, being the first report of social wasps for the Brazilian "campos rupestres". The main species regarding number of individuals were Trigona spinipes (Fabricius), Apis mellifera L., Frieseomelitta francoi (Moure), and Bombus brevivillus Franklin. About 48% of the species were represented by a single individual. There was an inversion in the dominance rank when the species biomass was considered. B. brevivillus, A. mellifera, T spinipes, and other species represented by 15 individuals or less, such as the social wasps Synoeca cyanea (Olivier), Polistes canadensis (L.) and Myschocyttarus drewseni (Saussure), and the bees Eufriesea nigrohirta (Friese), Xylocopa grisescens Lepeletier and Megachile (Pseudocentron) sp.l were the predominant species. The use of biomass in diversity analysis permitted to detect differences in the relative contribution of species in hierarchy dominance. The comparison between bee faunas from different areas indicates a large similarity of the sampled fauna in Palmeiras (Bahia State) with neighboring ecosystems, although with low values of similarity.

    Full Text Available Hypotheses are presented on the evolution of structural patterns of secondary metabolites (flavonoids and foliar wax alkanes and fatty acids of families of "campos rupestres". The distribution of fatty acids is given for genera of Lythraceae, with emphasis on Cuphea (supposedly more advanced and Diplusodon. Compounds with saturated short chains represent a derived condition in Lythraceae although they are probably restricted to Cuphea. It is suggested that evolution selected for more complex flavonoid patterns in Cuphea, with the inclusion of C-glycoflavones and methoxylated flavonols (rhamnetin and isorhamnetin, which are not found in members of Diplusodon and Lafoensia. The supposedly primitive groups of Eriocaulaceae (e.g., Paepalanthus presented more complex flavonoid patterns characterized by flavones and flavonols, the latter frequently being 6-hydroxylated or methoxylated. More advanced groups of Eriocaulaceae (e.g., Leiothrix and Syngonanthus apparently possess only flavones, C-glycoflavones are a salient feature of species with smaller habits. In Velloziaceae, members of the primitive subfamily Vellozioideae show distribution of alkanes of foliar epicuticular wax in which C27, C29 or C31 predominate; members of the derived subfamily Barbacenioideae usually show distributions with a predominance of C33 or C35, while species of Pleurostima (Barbacenioideae have C31 as the main homologue, thus being intermediate between the two subfamilies. It is suggested that the evolution of alkanes in Velloziaceae follows a trend toward elongation of carbon chains. The condition of advanced or primitive chemical patterns is inferred from the results of cladistic analyses based on morphological characters (Eriocaulaceae and Lythraceae, and morphological and molecular characters (Velloziaceae.

O projeto foi conduzido em vinte propriedades particulares, em Cambará do Sul, utilizando áreas de campo nativo que estavam sendo normalmente utilizadas em pastoreio por bovinos de corte e/ou ovinos, e que não tinham sofrido nenhum tipo de melhoria, reforma ou recuperação (exceto queimada, no mínimo nos últimos 20 anos. Colheram-se nas diversas estações, durante um ano, e dentro de uma mesma área predeterminada em cada propriedade, amostras para determinar as concentrações de ferro, manganês, cobre e zinco. Verificou-se efeito do mês de coleta sobre todos os minerais analisados. Constataram-se teores suficientes de Mn e Fe para todas as categorias de bovinos de corte analisadas. Entretanto, algumas amostras apresentaram níveis tóxicos aos animais. Os teores de Cu não são suficientes para todas as categorias de bovinos em alguns meses do ano. Os teores de Zn estiveram abaixo das exigências mínimas para bovinos de corte.

    Full Text Available The spring of 1995 marked (he discovery of (he Cave of the Moro with a grout of horse engravings of undoubted Upper Palaeolithic date. The numerous other finds that have been made in recent years in the zone of the Campo de Gibraltar suggest that it is an area of great importance. Both the rock art and the material culture evidence, in the open air or in rock shelters, has continually increasing potential for study. Furthermore this group of sites represents the most southern Palaeolithic rock art in Europe.

    En la primavera de 1995 se produjo el descubrimiento de la Cueva del Moro con un conjunto de figuraciones grabadas de équidos con. una filiación superopaleolítica indudable. Los numerosos hallazgos que se están produciendo desde hace unos años en la zona del Campo de Gibraltar nos indican que se trata de una área con una gran importancia y expectativas de estudio. Los hallazgos, tanto de arte rupestre como de cultura material, en estaciones al aire libre o en abrigos rocosos completan un panorama cada día más prometedor. Además este nuevo conjunto representa el arte rupestre paleolítico más meridional de Europa.

  12. Petrochemical characteristics of Serra do Meio alkaline granite (Campo Alegre de Lourdes - Bahia State)

    International Nuclear Information System (INIS)

    The Serra do Meio granite outcrops near the town of Campo Alegre de Lourdes, north-northeast of Bahia State. The granite is intrusive into micachists, which are correlatives of the Salgueiro-Cachoeirinha Group (Early Proterozoic), during early to the syn-tectonic shear phase. The geological setting also comprises a phosphatic rock-bearing carbonatitic complex and gabbroid complexes with one of the main world resources of Fe-Ti-V. The granite mineralogical composition grades from Aegerine-augite alkali-feldspar granite/syenites to Leuco alcali-feldspar granite. The geochemical analysis shows SiO2-enrichment (67 to 76%), in alkalis (Na2+K2O, 7,5 to 12,5%), Nb (up to 680ppm), Zr (up to 2,390ppm), Y (up to 250ppm) e REE (up to 796ppm). The geochemical behaviour is peculiar to alkaline series, denoting a silica-oversaturated, potassium-rich, magma. The chondrite-normalized REE patterns display a first group with smooth slopes from the La to Lu, and a second one with negative slopes. Negative Eu anomalies are displayed in all the patterns. The first group is HREE-enriched, with low fractionation ratios. Samples with milonytic fabrics and higher fractionation ratios are related to the second group, suggesting the interaction of metassomatic fluids and the alkaline magma. Discriminant diagrams for Nb, Y and Rb, coupled with geophysical data, point to an intrusive granite in an extensional within a plate tectonic setting of attenuated continental crust. (author)

    Full Text Available O fogo é um distúrbio recorrente em muitas áreas da Chapada Diamantina, geralmente originado por ação antrópica e que ocasiona rápidas mudanças nas comunidades. Este trabalho objetiva conhecer a composição e estrutura da vegetação de uma área de campo rupestre recém-queimada no Parque Nacional da Chapada Diamantina, Bahia, Brasil, situada entre 700 e 800 m acima do nível do mar, visando discussão das estratégias de regeneração das espécies mais conspícuas e das similaridades florísticas entre áreas com e sem distúrbio recente de fogo. Foi realizado um censo das espécies de plantas vasculares ocorrentes em 16 parcelas de 10x10 m, sendo as coberturas estimadas em cinco subparcelas de 2x2 m de cada parcela. Foram encontradas 85 espécies de 34 famílias, sendo 11 de monocotiledôneas, 22 de eudicotiledôneas e uma de monilófita.

Os Campos Rupestres (G-corrigido = 23,41; p-valor = 0,0001 e os Campos Úmidos (G-corrigido = 80,34; p < 0,0001 diferiram do Espectro Biológico Normal de Raunkiaer, bem como diferenciaram-se entre si (χ2 = 24,23; p < 0,0001. Uma Análise de Correspondência Distendida separou Campos Rupestres de Campos Úmidos devido às maiores frequências de fanerófitos nos primeiros e de hemicriptófitos e terófitos nos últimos. Sugerimos como hipóteses que os micro-habitats favoráveis ao desenvolvimentode fanerófitos sejam mais comuns nos Campos Rupestres de afloramento do que nos Campos Úmidos, ocorrendo o contrário com os micro-habitats favoráveis aos hemicriptófitos. Esta forma de vida pode apresentar melhor ajustamento ao encharcamento do solo do que os caméfitos e geófitos. A estratégia de escape apresentada pelos terófitos seria pouco eficiente em Campos Rupestres de afloramento devido à escassez de solo para proteção das sementes.

Esse é o caso davegetação sobre afloramento rochoso da Estação Experimental de Itapeva – EEI, situada no sudoeste do Estado de São Paulo, região que abriga remanescentes de Cerrado e Mata Atlântica. Visando caracterizar e classificar essa vegetação, foram realizadas coletas mensais de material botânico no período de agosto de 2008 a fevereiro de 2010. A lista de espécies obtida foi comparada com a de campos rupestres e de altitude brasileiros. As comparações foram realizadas por meio de análise de agrupamento, “TWINSPAN” e “NMS”. Foram encontradas 135 espécies, 48 famílias e 108 gêneros. As famílias mais representativas foram Fabaceae, Asteraceae, Bignoniaceae, Myrtaceae, Melastomataceae, Poaceae, Apocynaceae, Sapindaceae e Orchidaceae. A análise de agrupamento com os dados de distribuição de riqueza entre famílias sugeriu maior afinidade florística entre o afloramento rochoso estudado e os campos rupestres. Para os dados de composição de espécies, os diferentes métodos de ligação agruparam a área de estudo ora com campos de altitude ora com campos rupestres. A “NMS” evidenciou o caráter contínuo da variação florística, mas reiterou a maior similaridade entre a área de estudo e os campos rupestres. A “TWINSPAN” reforçou essa hipótese e apontou a família Fabaceae e as espécies Miconia albicans (Sw. Steud. e Periandra mediterranea (Vell. Taub como indicadoras de campos rupestres. O tipo de solo, formado a partir de rochas areníticas, constitui o fator determinante mais plausível para as relações florísticas encontradas.The classification of vegetation communities is not an easy task, especially regarding less studied vegetation types.

    Full Text Available The theme of this work is the evolution of agrarian systems in the region of Campos de Cima da Serra CCS, located in the northeastern area of Rio Grande do Sul. We seek the history of space occupancy, from its earliest inhabitants, the Indians, to follow the historical mode of environmental exploitation and understand how it evolved to its current structure, focusing on two specific goals: to find historical references realizing the production of Serrano cheese (QS, and searching for the origins of the family farmers of CCS. These family farmers are dedicated to beef cattle, in enterprises where the workforce is familiar, the predominantly agrarian structure is considered small for the activity, the economic rationality gives the priority to the social reproduction of the family. In CCS, an alternative to supplement the income of family farmers is the production of QS. In this study, we used as an analytical tool the Theory of Agrarian Systems, which allowed to reconstruct the history of the interaction of society with their natural surroundings, which showed that the QS is a cultural heritage of the CCS.

Foram calculados os índices de atividade e intensidade de produção de botões, flores, frutos imaturos e frutos maduros ao longo de 2001. A influência do clima sobre a fenologia foi avaliada por Análise de Correspondência Canônica (CCA. A germinação foi avaliada a temperaturas constantes de 15-35 ºC (com intervalos de 5 ºC em câmaras de germinação com fotoperíodo de 12 h. A variância dos dados explicada pela CCA foi de 72,8%. A temperatura média do ar, evaporação e radiação solar global apresentaram altos coeficientes de correlação com a fenologia. O florescimento ocorreu nos meses quentes e úmidos, a maturação de frutos se estendeu na estação seca e fria, e a dispersão das sementes, logo antes da estação chuvosa. A germinabilidade foi superior a 80% nas temperaturas de 20-30 ºC, faixa ocorrente no período chuvoso logo após a dispersão das sementes. Comparações com outros estudos indicam que a dispersão e rápida germinação nesses períodos são fortes fatores adaptativos dentro do gênero. Os resultados são importantes para a compreensão dos fatores que afetam o sucesso reprodutivo e expansão populacional, e devem ser considerados para ações de manejo desta espécie rupestre endêmica.The reproductive phenology and seed germination of a Kielmeyera regalis population, from Serra do Cipó (MG, Brazil, were studied.

    Full Text Available Desde hace algún tiempo venimos sosteniendo, junto con otros prehistoriadores, la necesidad de revisar las fases establecidas para el desarrollo del arte rupestre cuaternario y su cronología. El sistema preconizado por Breuil tiene la necesaria flexibilidad para permitir las rectificaciones que el tiempo necesariamente irá imponiendo a raíz de la investigación moderna. De ahí que nuestras notas o reflexiones sean más que críticas que tiendan a desvalorizar el sistema actualmente admitido, simples rectificaciones orientadas en los nuevos puntos de vista, producto de los descubrimientos más recientes. En este sentido hemos de hacer patente la importancia que la cueva del Parpalló (Gandía, con una estratigrafía clara y definida y con una serie de hallazgos de arte mobiliar perfectamente datados, tiene para el estudio del arte rupestre hispanofrancés, del Paleolítico superior.

En esta ultima region, objeto de este trabajo, se catalogaron 14 abrigos con pinturas, la mayoría de los cuales situados en la granja de Otjompaue Sud. El arte rupestre de esta zona está en vías de desaparición a causa de la alteración de las losas que forman los abrigos, a pesar de ello se han podido verificar escenas de caza, lucha enfermedad o vejez, pastoreo y danza, junto a grupos de animales salvajes y domésticos, realizados en un estilo naturalista y combinando a menudo dos colores, blanco y rojo, en una misma figura. La falta de trabajos arqueológicos hace prácticamente imposible datar las pinturas aunque parece intuirse una cronología del período Wilton con cerámica, es decir, dentro del primer milenio a.

  14. The Late Holocene upper montane cloud forest and high altitude grassland mosaic in the Serra da Igreja, Southern Brazil

    Full Text Available Many soils of the highlands of Serra do Mar, as in other mountain ranges, have thick histic horizons that preserve high amounts of carbon. However, the age and constitution of the organic matter of these soils remain doubtful, with possible late Pleistocene or Holocene ages. This study was conducted in three profiles (two in grassland and one in forest in Serra da Igreja highlands in the state of Paraná. We performed δ13C isotope analysis of organic matter in soil horizons to detect whether C3 or C4 plants dominated the past communities and 14C dating of the humin fraction to obtain the age of the studied horizons. C3 plants seem to have dominated the mountain ridges of Serra da Igreja since at least 3,000 years BP. Even though the Serra da Igreja may represents a landscape of high altitude grasslands in soils containing organic matter from the late Pleistocene, as reported elsewhere in Southern and Southeastern Brazil, our results indicate that the sites studied are at least from the beginning of the Late Holocene, when conditions of high moisture enabled the colonization/recolonization of the Serra da Igreja ridges by C3 plants. This is the period, often reported in the literature, when forests advanced onto grasslands and savannas.Muitos solos dos picos da Serra do Mar, como em muitas outras serras, apresentam horizontes hísticos espessos com elevados estoques de carbono. No entanto, a idade e constituição da matéria orgânica destes solos ainda é pouco conhecida e não se sabe se é predominantemente proveniente de comunidades de plantas do final do Pleistoceno ou do Holoceno. Este estudo foi realizado em três perfis, dois em campos altomontanos sobre Organossolos (1.335 m s.n.m e um em um colo (ponto de sela, onde a floresta altomontana sobre Gleissolos alcança seu patamar mais alto (1.325 m s.n.m.

  16. The Leiobunum rupestre species group: resolving the taxonomy of four widespread European taxa (Opiliones: Sclerosomatidae

    Directory of Open Access Journals (Sweden)

    2016-07-01

    Full Text Available Within the central European opilionid fauna the widely used species names Leiobunum rupestre Herbst, 1799 and Leiobunum tisciae Avram, 1968 pose taxonomic and distributional problems. In addition, Nelima apenninica Martens, 1969 is close to L. tisciae in terms of external and genital morphology, but is specifically distinct. While coxal denticulation is largely lacking in N. apenninica, the validity of the genus Nelima Roewer, 1910 is questioned again. In addition, Leiobunum subalpinum Komposch, 1998, a recently described novelty from the eastern Alps, is closely related to L. rupestre. The four species are combined as the morphologically defined Leiobunum rupestre species group. Except for L. subalpinum, they were found to be allopatrically distributed from the Carpathians across central and Northwest Europe to the south-western Alps. The latter species is locally sympatric and partly elevationally parapatric to L. rupestre. Leiobunum tisciae is a recently introduced name and here recognized as a junior synonym of a number of taxa described much earlier, of which L. gracile Thorell, 1876 is re-introduced as oldest available name. Detailed morphological and distributional data for all taxa are presented.

Abstract This article presents the results of an analysis of the structure and production of speleotourism at Serra da Bodoquena, based on the precepts of ecotourism and ecological sustainability. The methodology included a survey of documents and fieldwork in natural cavities exploited for tourism. The discussion presents a technical-methodological approach for a speleotourism based on ecology and conservation. The study concludes that speleotourism can be established, not only as a specific market segment, but also as a new kind of tourism in the Serra da Bodoquena. Hence new opportunities for environmental management and control of impacts that may exist beyond the paradigms and current models should be identified.

    Full Text Available Questo lavoro non è un trattato sul campo geomagnetico e nemmeno
    una rassegna sull'argomento, almeno nel significato che normalmente
    si attribuisce al termine « rassegna »; esso è semplicemente
    un tentativo di condensare in termini comprensibili agli studiosi non
    specializzati ciò che oggi si sa o si ipotizza sul magnetismo terrestre
    e sulle sue cause. Chi scrive si è sempre trovato a disagio di fronte
    alle richieste di una spiegazione sull'origine del campo magnetico
    terrestre: o si cerca di cavarsela con poche parole (« si tratta di correnti
    elettriche indotte nell'interno della Terra » che possono forse accontentare
    chi non si occupa in modo particolare di problemi scientifici
    ma non possono soddisfare un fisico, oppure ci si sente obbligati a
    tentare faticosamente di approfondire, sia per capirli personalmente
    che per poterli poi spiegare agli altri, argomenti e ragionamenti che
    sono in realtà accessibili solo a un fisico teorico ben preparato. Apparentemente
    non esiste una via di mezzo, come del resto in molti altri
    campi della fisica contemporanea.
    La presente monografia rappresenta appunto il tentativo di trovare
    questa via di mezzo: nel terzo capitolo, dedicato alle teorie sull'origine
    del campo geomagnetico, si cerca di descrivere qualitativamente
    i principali processi fisici proposti come sorgenti del campo,
    dopo un accenno ai fondamenti fisici e matematici sui quali sono state
    elaborate le varie teorie. Senza farmi soverchie illusioni di essere riuscito
    nell'intento, mi dichiarerei tuttavia soddisfatto se questo lavoro
    destasse sull'argomento l'interesse di qualche giovane ricercatore, incoraggiandolo
    ad un approfondimento.

    Full Text Available The aim of this study was to inventory the mayfly fauna, based on nymphal and alate stages, in Serra da Mantiqueira and in Serra do Mar, São Paulo State, as well as to present information about habitats used by the genera. Nymphs were collected in several streams and mesohabitats with a Surber sampler and the winged stages with light attraction methods, entomological nets, and Malaise traps. In all, eight families and 33 genera were recorded, representing a very significant portion of the Brazilian fauna (80% of families and 49% of genera. Furthermore, it was possible to identify 11 species, of which two are new records for the state: Tricorythodes santarita Traver and Caenis reissi Malzacher. Despite the high diversity recorded, the accumulation curves presented an ascending form, indicating an increase in the number of genera with additional sampling effort. The high richness found in these areas are in agreement with the high biodiversity of the Atlantic Forest biome and the sampling effort employed, which included the use of different methods, the collection of both nymphs and winged stages, and the sampling of a large area with diverse streams and habitats.

    Full Text Available A partir del hallazgo de una cueva con pictografías en Isla de Pinos, en 1922, fecha anterior al descubrimiento de la caverna con dibujos rupestres de Lascoux, en Francia, se desató una fiebre por el estudio de esas célebres pinturas parietales entre arqueólogos y estudiosos de la historia y la cultura cubanas. Un alto nivel abstraccional de los pictogramas de la cueva no 1 de Punta del Este en Isla de Pinos, aparentemente no coincidente con la cultura a que aparecen asociados los dibujos, planteó un enigma acerca del Arte rupestre de los aborígenes del País que ha llegado indemne prácticamente hasta el presente. Estudios precedentes de destacadas personalidades de la ciencia han permitido, gracias a su sistematicidad, una base de datos que es utilizada por los autores del presente trabajo para una contrastación de las tendencias de desarrollo del arte rupestre en Cuba mediante métodos computarizados.Los conceptos propios de la pintura y el arte plástico en general, en el estudio de estas manifestaciones en el País, son reenfocados con criterios homogéneos y el rigor científico necesario. Igualmente las referencias al nivel de desarrollo sociocultural de las comunidades aborígenes que se han supuesto sus autores, requirieron de un tratamiento especial de acuerdo con los conocimientos más actualizados sobre la arqueología en el momento de la realización del estudio; todo ello con el fin de deslindar objetivamente los endebles nexos entre autor y obra propios del arte rupestre. Los análisis desarrollados posibilitaron comprobar que los conceptos de figuración y abstracción en las comunidades aborígenes de Cuba concuerdan con las distintas fases de los procesos de “neolitización” en que aquellas se encontraban; y Punta del Este en Isla de Pinos es un caso particular que, no obstante, se enmarca coherentemente en un proceso de esta naturaleza.

  14. Equilibrium and Disequilibrium of River Basins: Effects on Stream Captures in Serra do Mar and Serra da Mantiqueira, Brazil

    DA Silva, L. M.

    2015-12-01

    Landscapes are mainly driven by river processes that control the dynamic reorganization of networks. Discovering and identifying whether river basins are in geometric equilibrium or disequilibrium requires an analysis of water divides, channels that shift laterally or expand upstream and river captures. Issues specifically discussed include the variation of drainage area change and erosion rates of the basins. In southeastern Brazil there are two main escarpments with extensive geomorphic surfaces: Serra do Mar and Serra da Mantiqueira Mountains. These landscapes are constituted of Neoproterozoic and early Paleozoic rocks, presenting steep escarpments with low-elevation coastal plains and higher elevation interior plateaus. To identify whether river basins and river profiles are in equilibrium or disequilibrium in Serra do Mar and Serra da Mantiqueira Mountains, we used the proxy (χ), evaluating the effect of drainage area change and erosion rates. We selected basins that drain both sides of these two main escarpments (oceanic and continental sides) and have denudation rates derived from pre-existing cosmogenic isotopes data (Rio de Janeiro, Paraná and Minas Gerais). Despite being an ancient and tectonically stable landscape, part of the coastal plain of Serra do Mar Mountain in Rio de Janeiro and Paraná is in geometric disequilibrium, with water divides moving in the direction of higher χ values. To achieve equilibrium, some basins located in the continental side are retracting and disappearing, losing area to the coastal basins. On the contrary, there are some adjacent sub-basins that are close to equilibrium, without strong contrasts in χ values. The same pattern was observed in Serra da Mantiqueira (Minas Gerais state), with stream captures and river network reorganization in its main rivers. The initial results suggest a strong contrast between erosion rates in the continental and the oceanic portions of the escarpments.

  17. The Serra do Carambei Granite - PR and the uraniferous anomalism

    International Nuclear Information System (INIS)

    The Serra do Carambei Granite forms a pluton relatively homogeneous, covering about 33 km2, cropping out as an elongate retangular body trending NE-SW, being emplaced in the Cunhaporanga Granitoid Complex. Its characteristics indicates a kind of hololeucocratic granite, equigranular, medium to coarse-grained, consisting predominantly of microperthitic alkali-feldspar, quartz and a small amount of biotite (less than 1%), thus being classified as an alaskite. Chemical data allows a classification in the group of granite with high contents of silica (74-76% Wt. SiO2), dominantly alkaline chemism and hypersolvus character, derived from a parental magma under saturated in water with distinguished features of granitoids from the magnetite series and types I and A granites. The pluton shows important chemical variations due to weathering processes. However detailed chemical studies reveal the presence of anomalous concentrations of trace elements such as U, Sn, Nb, Y, Zr, the Serra do Carambei Granite lacks economically important mineralizations because of the absence of well-developed tardi/pos-magmatic processes that could concentrate them. The SW side of the granite is cut by leucocratic rhyolite dykes that show some radiometric anomalies. These rocks, which are highly diferentiated, were emplaced contemporaneously to the Serra do Carambei Granite. Although petrographic and chronological similarities are found between the uraniferous alaskite of Roessing (Namibia) and the Serra do Carambei Granite anyhow it was not possible to establish any lateral continuity with the uranifeous Pan-African Province.

Furthermore, it was possible to identify 11 species, of which two are new records for the state: Tricorythodes santarita Traver and Caenis reissi Malzacher. Despite the high diversity recorded, the accumulation curves presented an ascending form, indicating an increase in the number of genera with additional sampling effort. The high richness found in these areas are in agreement with the high biodiversity of the Atlantic Forest biome and the sampling effort employed, which included the use of different methods, the collection of both nymphs and winged stages, and the sampling of a large area with diverse streams and habitats.O objetivo do trabalho foi inventariar a fauna de Ephemeroptera, com base em ninfas e estágios alados, da Serra da Mantiqueira e Serra do Mar no estado de São Paulo, bem como gerar informações sobre os hábitats utilizados pelos gêneros registrados.

    2013-09-01

    The capability of determining the flow-by-flow stratigraphy and the long-distance correlation of lava flows in large continental volcanic provinces leads to a considerable advance in the understanding of processes related to generation and evolution of the lavas. The Paraná volcanic province is exposed along the Serra Geral cuesta of southern Brazil in a steeply inclined, 1,000-m-high section starting 40-m above sea level. Each of the 10-20 pahoehoe flows and rhyodacite flow units has a unique chemical composition. Integrated with field stratigraphy and gamma-spectrometric measurements, this leads to the establishment of the correct stratigraphic sequence in each of three different vertical sections. The number of flows integrating the three serras is 26 ("serra" is a mountain range in Portuguese). Each serra has basaltic andesites at the base, whereas rhyodacites are intercalated with basaltic andesites at the top. Three basaltic andesite flows and one rhyodacite flow unit are correlated between Serra Umbu and Serra Boa Vista (10 km). In the Serra Faxinal, a thick (170 m) sill at the base correlates with flow 13F, whereas a dike-sill in the Graxaim quarry (24 km distance) correlates with flow 3F. One basaltic andesite and two rhyodacite flow units correlate between Serra Faxinal and Serra Umbu (50 km). The results are most significant for the understanding of large tracts of continental volcanic provinces with use of common geochemical and gamma-spectrometric techniques.

Todos ellos forman parte de un conjunto de centros cultuales distribuidos por el centro-oeste de España, aunque estrechamente relacionados con otros existentes en el ámbito galaico y en la Celtiberia. Es probahle que, en algunos casos, haya habido pervivencias en el mundo romano, pero lo que define su ceremonial y su liturgia —aparte, claro está, su simbolismo— pertenece a una época anterior. De ahí el que, como ya hemos consignado en otras ocasiones, adscribamos al mundo prehistórico y protohistórico la existencia de tales monumentos religiosos. Como novedad, dentro del conjunto de santuarios que aquí presentamos, aparecen, en uno de ellos, representaciones de manos y del aparato genital masculino. Otro de los que hemos estudiado, muestra una gran profusión de hoyuelos, de lo cual ofrecemos una interpretación. Nuestra tesis es que es preciso recurrir a la investigación de la simbologia primaria, precisamente aquélla que, según todos los indicios, marcaba las pautas de representación principales del hombre en la Antigüedad.ABSTRACT: In this article, we offer a study of various prehistoric rupestrian shrines which have been unknown until now.

It is probable that, in certain cases, these centres existed as such during the Roman Empire but those features characteristic of their ceremonial and liturgical rites —apart from their symbolism— belong to previous times. That is why, as we have set down in previous occasions, we adscribe the existence of such religious monuments to the prehistoric and protohistoric world.

    2005-01-01

    Full Text Available En las artes rupestres del mundo entero, los animales aparecen casi siempre representados de perfil. Un examen detallado pone de manifiesto que, contrariamente a la tendencia a la orientación siniestra que parece "natural" a los psicólogos, los artistas prehistóricos eligen, por aplastante mayoria, el perfil derecho. Dos regiones vecinas muestran, en ocasiones, tendencias completemente opuestas. Estas elecciones mayoritarias son probablemente de origen culttural y, por ello, merecen toda la atencion de los prehistoriadores. En el caso concreto del arte parietal paleolítico de Europa Occidental, la mayor parte de las especies animales están orientadas mayoritariamente hacia la izquierda, a excepción del caballo. Parece que las orientaciones de los animales reunidos en paneles tienen una incidencia en el sentido del mensaje y dependen de una propiedad semiótica descrita por U. Eco bajo el nombre de toposensibilidad.

    Full Text Available Groundwater with anomalous fluoride content and water mixture patterns were studied in the fractured Serra Geral Aquifer System, a basaltic to rhyolitic geological unit, using a principal component analysis interpretation of groundwater chemical data from 309 deep wells distributed in the Rio Grande do Sul State, Southern Brazil. A four-component model that explains 81% of the total variance in the Principal Component Analysis is suggested. Six hydrochemical groups were identified. δ18O and δ2H were analyzed in 28 Serra Geral Aquifer System samples in order to identify stable isotopes patterns and make comparisons with data from the Guarani Aquifer System and meteoric waters. The results demonstrated a complex water mixture between the Serra Geral Aquifer System and the Guarani Aquifer System, with meteoric recharge and ascending water infiltration through an intensive tectonic fracturing.

    The Serra do Mar (SM) mountain range located along the southeast Brazilian continental margin is characterized by a low-lying coastal plateau separated from the elevated inland plateau by a steep escarpment. This morphology is a result of reactivation of Precambrian shear zones since the break-up of the Western Gondwana and opening of the South Atlantic Ocean in Early Cretaceous (1). Previous Thermochronological data from southeast Brazilian highlands (2,3), indicates that the landscape evolution is associated with several distinct exhumation events. In order to clarify the intensity and duration of the post-break up tectonic processes that shaped the SM we have undertaken a low temperature thermochronology study of crystalline basement, from the plateaus and escarpments situated between south of Rio de Janeiro and São Paulo state. Apatite fission track (AFT) and (U-Th/He) and (AHe) dating has been combined with geologic information to generate precise thermal histories and make initial attempts to quantify the amount of exhumation. AFT ages range from 145 to 53 Ma whereas preliminary AHe ages range from 75 to 37 Ma.

    Full Text Available Um inventário da fauna de aranhas foi realizado na Serra do Cachimbo, no Campo de Provas Brigadeiro Velloso, município de Novo Progresso, Pará. As coletas ocorreram em duas expedições, uma na estação seca (agosto e setembro de 2003 e outra na chuvosa (março e abril de 2004. Cada expedição contou com a participação de três coletores. O esforço de amostragem foi de 240 amostras, sendo 96 através de guarda-chuva entomológico e rede de varredura, 96 através de coleta manual noturna e 48 por triagem manual e extratores de Winkler. Foi comparada a diversidade de aranhas de quatro tipos de vegetação, Floresta Ombrófila Aberta, mata de galeria, áreas de Cerrado (Savana Arbórea e de Campina. As coletas resultaram em um total de 4.990 indivíduos, dos quais 2.750 adultos. Foram identificadas 427 morfoespécies em 37 famílias, sendo as mais abundantes Theridiidae, Salticidae e Araneidae e as mais ricas em espécies Araneidae, Salticidae e Theridiidae. As espécies representadas por apenas um indivíduo somaram 40% do total e apenas duas ultrapassaram cem indivíduos. A curva de riqueza específica estimada (ACE atingiu 614 espécies. A maior diversidade alfa (índice de Shannon-Wiener foi encontrada em Floresta Ombrófila, seguida pela mata de galeria, Campina e Cerrado. Tais diferenças entre as vegetações podem ser explicadas devido a variações na complexidade da vegetação e na disponibilidade de microhábitats em cada fitofisionomia.

    Full Text Available During the last years, one of the authors has turned her attention, increasingly, to the anuran fauna of the high forested ranges near the sea-board of S.E. Brazil. This has led to the finding of a number of very interesting frogs which do not occur in the lower, mesic, or, occasionally, xeric, open country. One of these forms is presented here. As it did not fit perfectly into any of the known genera, she decided to consult her fellow herpetologist at the National Museum, Mr. Antenor Leitão de Carvalho, who is interested in anatomy. He cleared an adult and a juvenille specimen; the osteological characters found are given below. Joint publication was decided upon, one author contributing her field-notes and the morphological characters and drafting the text, whereas the other contributed the osteology, drawings and measurements. The specific name was also chosen by Leitão de Carvalho, in homage to the late Professor Adolpho Lutz, a pioneer in the study of Brazilian frogs. In regard to the specific designation, the co-author and daughter of Adolpho Lutz wishes to publish the following.Ao correr dos últimos anos, a co-autora dêste trabalho vem se dedicando ao estudo da fauna anura das zonas mais elevadas das serras vizinhas da costa brasileira. Êste fato conduziu à descoberta, ou ao conhecimento mais exato, de certo número de formas muito interessantes que não ocorrem em altitudes menores ou na planície. Uma destas formas constitui o assunto do presente trabalho. Tratando-se de batrácio que não se enquadra perfeitamente em nenhum dos gêneros descritos, resolveu ela consultar o seu colega Sr. Antenor Leitão de Carvalho, conhecedor exímio de anatomia, que diafanisou um exemplar adulto e outro juvenil. Os caractéres osteológicos encontrados levaram á criação de mais um gênero cujos caractéres diferenciais são enumerados abaixo.

    Full Text Available This work is included in one of the research lines of the Prehistory Area of the Department of Historical Sciencies (University of Cantabria, devoted to the documentation of regional rock art. The palaeolithic figures at Covalanas are a sinchronic and ordered group, that uses the pointed-line technique and other pictorial procedures close to it. From the stylistic analysis of figures and signs, and from comparisons with other well-dated «sanctuaries», an advanced Solutrean date can be proposed for these paintings.

    Full Text Available O presente trabalho investigou a evolução do relevo da média Serra do Espinhaço Meridional (SdEM, região que delimita três das mais importantes bacias hidrográficas do sudeste brasileiro: à oeste, a do rio São Francisco e, à leste, as dos rios Doce e Jequitinhonha. Os procedimentos metodológicos basearam-se na utilização de dois tipos de análises. A primeira baseou-se em observações de campo e em análises cartográficas e visou reconhecer áreas onde os processos erosivos eram mais ativos. A segunda objetivou mensurar a atual denudação geoquímica em 16 bacias hidrográficas que se localizam nas duas vertentes da média SdEM. Os resultados demonstram que a litologia predominante – quartzito – é extremamente resistente aos processos intempéricos e desnudacionais e que o arcabouço litoestrutural controla os processos desnudacionais da área investigada. Demonstram ainda que, embora a vertente leste apresente relevo mais dissecado, fato que indica que no passado nesta vertente os processos desnudacionais eram mais intensos, é na vertente oeste que, atualmente, os processos desnudacionais geoquímicos são mais agressivos.

    International Nuclear Information System (INIS)

    The Serra Dourada granite is related to one of the various large tin-bearing domic structures that occur in central-eastern Goias, where rocks of Uruacu and Brasilia folded belts and of Goias median massif crop out. The present study was undertaken in the southern part of Serra Dourada as an attempt to contribute to the petrologic, metallogenetic and stratigraphic aspects of the granitic rocks present in that region. The methodological approach consisted of the preparation of a 1:45.000 geological map and included the obtention of petrographic, ore microscopic and geochronological data, as well as the determination of major element concentrations in rocks and some minerals. Trace elements were only determined for rocks. (author)

    Full Text Available RESUMEN: El arte rupestre es una forma especializada de cultura material, pero raras veces puede por si mismo proporcionar los datos que nos permitan conocer el tiempo de su realización, de ahí que se halla tenido que recurrir con frecuencia a la identificación de motivos paralelizables y las que se derivaban de la posible evolución estilística de los motivos para obtener un índice relativo de aproximación cronológica. El hallazgo de trece conjuntos en la provincia cacereña dentro de contextos con materiales muebles, posibilita una reducción del relativismo con el que veníamos trabajando y abrir nuevas vías de interpretación a partir de un enmarque cronológico más preciso.ABSTRACT: The rupestrian art is a specialised form of material culture, but it can hardly ever povide the data necessary to know the time when it was made, so that it has often been required to fall back on parallel motives and the data coming from the possible stylistic evolution ot these motives to get a relative Índex of chronological approach. The find of thirteen sets in the province of Cáceres in contexts with material furniture makes possible a reduction of this relativism wich we have been working with and opens new paths of interpretations from a more precise chronological framework.

Pero como desde hace algún tiempo me encuentro en radical disconformidad con la mayoría de mis colegas, nacionales y extranjeros, respecto a la etapa histórico-cultural que se viene asignando a esta extraordinaria manifestación artística de la Prehistoria peninsular, creo que ha llegado el momento de encuadrar mis ideas y opiniones en torno a los distintos problemas que este arte tiene planteados. Por adelantado digo que no creo haber hallado la solución por todos tan buscada y que al orientar mi exposición hacia nuevos derroteros me ha guiado el propósito de replantear desde puntos de vista algo más rigurosos la problemática de este arte y librar de prejuicios un camino por el que la investigación pueda progresar libre de todos los escolasticismos.

Breuil en los años 33 al 35. No es que desde esa fecha no se haya descubierto nada sobre el tema, si se ha descubierto, lo que sucede es que ninguno de los hallazgos se han publicado con los calcos y fotografías que era de esperar y la noticia de los mismos no ha rebasado nunca, o muy pocas veces el ámbito local o regional, en cualquier caso no se les ha prestado la atención debida. Por eso queremos hoy traer una muestra de estos descubrimientos, cumpliendo así dos objetivos: en primer lugar dar a conocer con calcos y fotografías recientes las nuevas pinturas y en segundo lugar rendir un sincero homenaje a todas aquellas personas que con entusiasmo, sacrificio y desinterés se han ocupado en buscar y reunir datos tan valiosos para la ciencia prehistórica, labor siempre dura y mal pagada, pero muy útil para quien posteriormente quiera hacer un trabajo de conjunto. Por ello con motivo de la tesis que tenemos en curso de preparación, no tenemos más remedio que reconocer, respetar y agradecer el trabajo realizado por estas personas, unas al brindarme su amistad y acompañarme como D. Jesús Cánovas y D. Graciano Baus, otras al indicarme los lugares de palabra y por escrito, otras finalmente al no haber ocultado la noticia y autorizarme a darla.

Entretanto, nem todas as pessoas se beneficiam com a atividade, como deficientes e pessoas com mobilidade reduzida, pois não podem usufruir dos espaços e atrativos turísticos devido à falta de adaptações. Assim, esta pesquisa tem como objetivo discutir e analisar a infraestrutura do Parque Nacional Serra da Capivara – PI, Patrimônio Cultural brasileiro, no que diz respeito à acessibilidade. Para tanto, realizou-se uma pesquisa bibliográfica sobre o tema e em uma pesquisa de campo, durante os meses de julho a setembro de 2010, com observação direta da área, coleta de dados, entrevistas e conversas informais. Percebeu-se, então, que a infraestrutura do Parque possui algumas adaptações, destinadas principalmente a cadeirantes, mas de maneira superficial e em alguns casos, incorreta.Palavras-chave: turismo acessível; unidade de conservação; deficiência. AbstractTourism provides many benefits for both as destinations for people who practice it. However, not all people benefit from the activity, such as the disabled and persons with reduced mobility because they can not make use of spaces and tourist attractions due to the lack of adjustments.

    Full Text Available A uva 'Chardonnay' é uma cultivar originária da região da Borgonha, França. Na Serra Gaúcha, RS, ela adquiriu notoriedade em razão da produção de vinho branco varietal e da sua utilização como base para espumante. Na safra de 2007, representou 6,3% do total das uvas brancas viníferas processadas. Em vista disso, este trabalho foi realizado com o objetivo de avaliar a composição físico-química do vinho Chardonnay elaborado na Serra Gaúcha, visando à formação de um banco de dados, à determinação de sua identidade varietal e a sua caracterização regional. Analisaram-se 125 vinhos, safras 1998 a 2005, de 28 vinícolas. As análises foram realizadas na Embrapa Uva e Vinho, em Bento Gonçalves, RS. As determinações clássicas foram efetuadas por meio de métodos físico-químicos; os compostos voláteis, por cromatografia gasosa; e os elementos minerais, com exceção do P, por espectrofotometria de absorção atômica. Os resultados mostram que o vinho Chardonnay enquadrou-se nos limites estabelecidos pela legislação brasileira. Observaram-se valores elevados de álcool, extrato seco reduzido, cinzas, prolina e K, variáveis que garantem boa estrutura e corpo ao vinho branco; e teores baixos de compostos voláteis, especialmente de álcoois superiores, que favorecem os aromas frutados e florais.'Chardonnay' is a grapevine cultivar which origin is in the Burgundy region, France. It acquired economic importance in the Serra Gaúcha viticultural area, Brazil, due to the production of varietal white wine and sparkling wine. In 2007 it represented 6.3% of the total vinifera white grapes processed. Because of its importance to the wine industry, the physicochemical composition of Chardonnay wine from the Serra Gaúcha was evaluated to develop a databank and to establish its varietal identity and regional characterization. Chardonnay wines 125 samples from the 1998 to 2003 vintages, made by 28 wineries, were analyzed. Analyses

    This paper presents a floristic survey of the wood component of cerrado s.s. (eastern face) and gallery forest (western face) areas carried out in the southern part of the Serra de Maracaju. The dispersal syndromes and floristic relations of this portion of the Serra were compared to those of other formations from different regions of Brazil. Between October 2007 and September 2008, monthly collections identified 144 species. As for dispersal syndromes, zoochory prevails, followed by autochory and anemochory. The gallery forest is a heterogeneous formation that shelters floristic elements shared with the Atlantic rain forest, the Amazonian forest, semi-deciduous seasonal forests and dry forests of the Pantanal. Low similarity between the two areas analyzed makes this region unique and suggests that the Serra de Maracaju is greatly influenced by the semi-deciduous seasonal forests of the southeastern region.

    Full Text Available O campo da Psicologia Social é apresentado como território fértil, na contemporaneidade, para constituir-se como um laboratório para a produção em Ciências Humanas, uma vez que, no século XX, cada vez mais o social foi em direção ao psicológico. Neste campo, nosso embate dá-se no modo como entendemos o hífen pressuposto na integração psicossocial. A autora propõe que, entre o psicológico e o social, o hífen domina, pois ele é a própria essência relacional que é inerente a cada um dos elementos. Sugere que o modelo para entender o homem e suas circunstâncias proposto por Freud imbrica de forma indissociável o psicológico e o social, a ontogênese e a filogênese, com uma potência que teve impacto sobre todo o campo das Ciências Humanas. A Psicanálise é um instrumento hermenêutico para colaborar na elucidação dos fenômenos sociais. A autora utiliza imagens construídas por Freud e Walter Benjamin e poemas de Carlos Drummond de Andrade para fortalecer o entendimento do hífen psicossocial tanto em sua ação multidimensional quanto em sua organização.

Se trata de tres sectores con motivos lineales, geométricos, pintados en rojo. En el faldeo de la misma sierra, se localizaron dos estructuras pequeñas de piedra pircada de forma circular. En la cima de otro afloramiento rocoso, ubicado 500 m al oeste de estas estructuras, se halló una acumulación oval de piedras. En este trabajo se resumen las características del conjunto arqueológico y se presentan los resultados de los sondeos realizados en una de esas estructuras. Se examina la contemporaneidad entre las estructuras y las pinturas rupestres y su posible filiación tehuelche. Se comparan estas pinturas con otras manifestaciones similares de la Región Pampeana. Por último, se exploran aspectos simbólicos y religiosos de las sociedades pampeanas tardías.In the Curicó hills (also known as the La China hill, in the Olavarría district, rock art has been discovered on walls and in shelters in the quartzite tabular outcrops of the Balcarce Formation. The paintings are in three sectors and consist of lineal and geometrical motifs painted in red. On the slope of the hill, two stone circular structures were detected, and on the top of the opposite hill an oval stone structure was also found. In this article, the characteristics of this archaeological material are summarised and the results from test pits, excavated in one of these structures is presented. The contemporaneity among the findings is examined as well as its possible tehuelche affiliation. Finally, the symbolic and religion dimensions of the Late Pampean indigenous societies are explored.

    1996-12-01

    Full Text Available Rock art deteriorates because of both environmental factors and visitor erosion which affect its conservation and, therefore, its study. Graphic recording carried out in the past is sometimes the only recorded evidence for what once existed. However, the graphic record also presents problems of preservation on the long-term, a problem particularly highlighted on modern color photographic materials. In this paper we deal with new approaches to solve this problem. We illustrate our work with the photographic collection about Levantine rock art, which belongs to the CSIC, and is held in the Department of Prehistory of Centro de Estudios Históricos. Two methods are highlighted: the use of the new Kodak Photo CD system, and the multiband Digital Imaging analysis.

    El deterioro que padece el arte rupestre tanto por factores ambientales como antrópicos atañe a su conservación e investigación en el futuro. La documentación gráfica, en algunos casos el único vestigio disponible, se ve limitada también por problemas de conservación a largo plazo, en especial cuando se trata de fotografía en color. En este trabajo se plantean nuevas líneas de investigación para solventar estos problemas a partir de una investigación en curso en el Departamento de Prehistoria del Centro de Estudios Históricos (CSIC. Se trata de la conversión del importante archivo fotográfico del Corpus de Pintura Rupestre Levantina a formatos digitales (Kodak Photo CD y la aplicación del tratamiento digital de imagen multiespectral a la investigación de estas manifestaciones artísticas.

    Full Text Available This study aimed to map and characterize the vegetation of the National Park of Serra de Itabaiana, with emphasis on the most abundant plant species, evaluating strategies for their conservation. There was a predominance of open formations of grassy fi elds, characterized as high-altitude grassland (3,289ha, mainly in areas of slopes. The forests are characterized as ecotones between Lowland Dense Rain Forest and Semideciduous Forest (2,643ha, mostly as secondary forest. The habitat called the White Sands (347ha, previously characterized as salt marshes, only occurs on the eastern side of Itabaiana and Comprida Serras, and it has a type of physiognomy normally associated with high-altitude grassland. The disturbed areas are concentrated at the edges of the park, roads and trails used by human visitors. Of these areas, regions with exposed soils are the most abundant, occurring in a total of 699ha; the brushwood (586ha is more frequent at the forest’s edge, originating from fi res caused by the cultivation of sugar cane; plantations and withdrawals of soil (131ha occur in areas close to settlements.agreste; description; protected areas; white sand

    We studied the amphibian community of the Private Reserve of Natural Heritage (RPPN) Serra Bonita, an area of 20 km(2) with steep altitudinal gradients (200-950 m a.s.l.) located in the municipalities of Camacan and Pau-Brasil, southern Bahia State, Brazil. Data were obtained at 38 sampling sites (including ponds and transects within the forest and in streams), through active and visual and acoustic searches, pitfall traps, and opportunistic encounters. We recorded 80 amphibian species distributed in 15 families: Aromobatidae (1), Brachycephalidae (3), Bufonidae (4), Centrolenidae (2), Ceratophryidae (1), Craugastoridae (7), Eleutherodactylidae (2), Hemiphractidae (2), Hylidae (42), Hylodidae (1), Leptodactylidae (7), Microhylidae (3), Siphonopidae (1), Odontophrynidae (3) and Pipidae (1). Species richness was positively correlated with monthly rainfall. Near 36% of the species were found in strictly forest environments, 15% are endemic to Bahia State and 77.2% are endemic to the Atlantic Forest biome. The large species diversity of this small area, the high degree of endemism and the taxonomic and biogeographic significance turn the Serra Bonita mountain into a hotpoint for amphibians within Brazil's Atlantic Forest hotspot.

    Full Text Available The Atlantic Forest is a priority area for the conservation of amphibians, with some regions already showing knowledge gaps. We analyzed the composition and richness of anuran species in an area of dense ombrophilous forest at Serra do Tabuleiro, the seasonal richness variation, and the daily activity of males during vocalization shifts. We collected samples of anurans from two permanent ponds and from a track within the forest for 14 months. We recorded 32 anuran species, among which Aplastodiscus cochranae, A. ehrhardti, and Hypsiboas poaju are included in the list of endangered species in the state. The highest number of species was associated to spring and summer. The most frequent anuran species were H. bischoffi, Adenomera araucaria, and Physalaemus nanus, registered throughout the study period. The daily activity of males was concentrated between 8 p.m. and 12 p.m., but some species keep vocalizing overnight, indicating that vocal activity can differ among species undergoing the same weather conditions. The diversity of anurans recorded in our study was high, including endangered species and species with poor biological knowledge, reinforcing the relevance of Serra do Tabuleiro as a priority area for preserving the Atlantic Forest.

    Full Text Available Serra da Capivara National Park and surrounding areas in Southeastern Piau State (Brazil were subjected to morphostratigraphical, sedimentological, and geochronological studies about superficial deposits in order to interpret quaternary paleoenvironmental events. The following sedimentary deposits associated with morphostructural units were identified: colluvial fans at Serra Branca Valley and Structural Staircases, and eluvial-colluvial deposits at Reverse of the Cuesta. There are also colluvial and alluvial deposits outside Serra da Capivara National Park. Many colluvial and alluvial deposits are contemporaneous and indicate a semiarid climate. According to luminescence dating (thermoluminescence and optically stimulated luminescence, the present landscape evolution began around 436 51.5 ka when the Piau River deposited clayey sediments. From 296.55 46.95 ka to 116.3 19.52 ka, the fluvial channel likely exhibited a braided pattern and deposited sand and gravel bars. Penecontemporaneous sands and muds with ages ranging from 202.75 32.81 ka, 135 16.4 ka to 117 14.5 ka were deposited on Serra da Capivara National Park hillslopes. A colluviation episode occurred between 84.7 13.4 ka to 76.2 9.35 ka, which lacks correlatable alluvial deposits. In the Northern hemisphere last glacial maximum, the colluviation and alluviation processes intensified. These depositional processes likely occurred between 15.8 1.9 and 10.35 1.76 ka, during the Holocene-Pleistocene transition.

    Serra da Estrela is the highest mountain in Portugal (1,993 m ASL) and part of the Iberian Central Cordillera. The mountain has a strong relief and a lithological diversity with several types of granitoids and metasediments. Most of the western plateau area was glaciated during the Last Glacial Maximum and its morphology is dominated by glacial landforms. Vieira (2004) produced a detailed geomorphological map of Serra da Estrela and described several sites showing stratified slope, head and debris-flow deposits. Based on the geomorphological analysis of the relationships between glacial and periglacial evidence, a first relative chronology was presented. However, a detailed and systematical sedimentological analysis has not been conducted before and absolute ages are also lacking. Micromorphology analysis has proven to be of considerable value in the interpretation of mountain soils and sediments. Such interpretation depends on identifying diagnostic features, indicating factors as the presence or absence of permafrost, thickness of the active layer, ice segregation and the operation of processes of mass-wasting. In this study, micromorphology was used to answer questions concerning the composition, structure, origin and depositional processes of relict slope deposits. Micromorphology allowed a systematic description of the physical characteristics of the sediments. Lamination and sorting, when preserved, are good evidence for overland flow. Features due to deformation (folds, boudins, coatings and tails due to the rotation of clasts) are associated with sliding. Other mass-movements such as debris flows, earth flows, and to a certain extent, dry grain flows may be characterized by similar microscopic facies, typically a poorly sorted, porphyric material. Porosity gives evidence for both liquefaction (debris flows) and frost-induced mass-movement (solifluction). The relict slope deposits of the Serra da Estrela show an increase in cryogenic micromorphological

    We received for examination a small colection of ticks captured in the National Park of the Serra da Canastra (MG), between 1979 and 1980. The authors demonstrated the existence of a broad co-accomodation of Amblyomma pseudoconcolor on Edentata of the family Dasypodidae, being Dasypodini the tribe more adjusted to this infestation. In conformity to the Figs 1 and 2, Dasypodini are probably the real hosts of A. pseudoconcolor and also the oldest hosts. For the first time, A. pseudoconcolor is also recorded on Cabassous tatouay, C. unicinctus, Priodontes maximus and Euphractus sexcincuts. Also for the first time A. pseudoconcolor and Amblyomma calcaratum were recorded in the State of Minas Gerais. The ectoparasites are deposited in the "Departamento de Parasitologia da Universidade Federal de Minas Gerais, Brasil".

    Full Text Available Nella storiografia filosofica spagnola non esiste, probabilmente, una definizione ambigua e problematica come quella che riguarda la cosiddetta "Scuola di Barcellona". La tesi principale di questo articolo è che tale scuola non giunse mai a nascere, ma ne esistette soltanto una forma embrionale che non poté maturare perché, in conseguenza della situazione politica venutasi a creare con la guerra civile (1936-1939, i suoi componenti si dispersero nell'esilio. Ciò nonostante, è possibile riconoscere alcuni tratti comuni, seppur labili e (forse non sostanziali, nella diaspora degli intellettuali catalani che rendono possibile definirla, con le dovute cautele, "Scuola di Barcellona". Tali caratteristiche comuni si possono far risalire a colui che, in un certo senso, fu il fondatore della scuola, essendo il principale maestro delle nuove leve filosofiche della Catalogna all'inizio del XX secolo: Jaume Serra Hunter.

    Antitumor, antimicrobial and antioxidant activities of basil were studied, along with its characterization in phenolic compounds, organic acids and soluble sugars. The results placed basil as a valuable candidate for functionalization and conservation of food products, maintaining their nutritional properties, while increasing their shelf life and potential health effects. The basil leaves were then incorporated in "Serra da Estrela Cheese", either in its dehydrated form or as a decoction. The cheeses were then subject to a nutritional evaluation, being characterized for their fatty acids, minerals and CIE color parameters. To assess the combined effects of plant incorporation and storage time, a 2-way ANOVA was used to process the results, further analysed through a linear discriminant analysis. Overall, basil leaves provided antioxidant activity to the cheeses, reduced the moisture, and preserved the unsaturated fatty acids and proteins. Comparing both incorporation types, the decoctions had a higher functionalizing and conservative effect. PMID:27080879

    Full Text Available The pig activity, as well as other livestock activities, is directly dependent on natural resources and therefore the lack of knowledge about the impact on water resources in the cattle industry could compromise the sector's growth. In this context, the water footprint comes as a comprehensive indicator of water use that evaluates which is the fuel used, directly or indirectly, to produce a particular product throughout the supply chain. In this context, this study aimed to evaluate the gray water footprint for pigs slaughtered in 2014 in Corede Serra/RS, in the confinement process. The gray water footprint in Corede Serra was 0.1346 km3. The municipalities of Parai (0.0142 km3, Nova Prata (0.0133 km3 and Serafina Correa (0.0103 km3 showed the largest footprints while the municipalities of São Marcos (0.00001 km3 and Bento Gonçalves (0.00002 km3 presented the smallest footprints. Because of the concentration of phosphorus in pig manure have presented a significant value (1.65 kg animal year-1 when evaluated under the total number of animals slaughtered in each municipality and considering the phosphorus concentration provided for in Conama Resolution n° 357/05, the demand is observed a large volume of water to phosphorus load assimilation. The gray water footprint can be reduced through the use of more efficient technologies for processing of manure, so that phosphorus is removed or reduced to low concentrations.

    This paper presents a petrographical characterization of shales from Albacora, Marlim and Marlim Sul fields (offshore Campos Basin, Brazil). The characterization program included petrography analysis of thin section of undisturbed shale samples, scanning electron microscope (SEM) images and energy dispersive spectrometry (EDS) analysis. The tests were realized with the purpose of obtaining information to observe the nature of the rock microstructure. From the results presented herein, the shales can be described as silty and calciferous. The description of the thin sections indicated that all the shale samples are very similar from the compositional and textural point of view. The samples are rich in clay minerals, that show small size grains and seem homogeneous, and carbonatic cement. The samples are constituted by calcite, quartz, kaolinite, smecite, illite, illite/smectite, kaolinite/illite/smectite, feldspar, plagioclase, dolomite, chlorite and pyrite. The samples showed a great amount of calcium, resultant from the microfossils, that covers partially the clay minerals. Pyrite is also observed as small grains disperse throughout the sample with form of agglomerated pyrite framboids, cubo-octahedral and octahedral crystals. The EDS show the presence of picks of Si, Al, Mg, K and Na particles, indicating the presence of clay minerals, calcite, pyrite and chlorite. (author)

    Full Text Available This paper proposes a mapping of landforms units for the southern portion of the middle third of the Serra do Espinhaço Meridional. The landforms units were delineated from the integrated analysis of thematic maps and satellite images that allowed the observation of changes in morphology, altimetry, slope, lithostructure and organization of the drainage network. The step of digital mapping, processed in the software ArcGIS 9.2, was based in the use of SRTM products (Shuttle Radar Topography Mission. The methodological procedures also included field work and literature research. The taxonomy of geomorphological mapping proposed by IBGE (2009 was applied , through which fourteen Geomorphologycal Units were individualized. The units are distributed amongst five different compartments as follows: two plateaux, two escarpments, six depressions, three sets of ridges and one set of intermediate levels. It was observed that the general layout of the units reflects the strong lithostructural control forced to regional relief. The differentiated resistance of the various lithologies in relation to denudational processes and the influence of neotectonic on landscape evolution are noteworthy.

    The interruption of important phenological series and the progressive disappearance of phenological observations in Catalonia led the Meteorological Service of Catalonia (SMC) to design and impulse a new phenological network promoted by the Climate Change Unit of this Met Service. The "Fenocat" network was born in March 2013, and currently has around fifty observers distributed throughout Catalonia that observe plants, birds and butterflies. We are providing data from different plant phenophases to PEP725 database. Besides this new phenological network (Fenocat), one of the aims of SMC is to rescue and preserve historical data from different observation points in Catalonia. We show in this poster the example of rescue and preservation of phenological data from la Serra d'Almos (in Tivissa, near Tarragona, Catalonia, NE Iberian Peninsula), an observation series that began in 1973. After digitalization process and quality control tasks, we show preliminary results of this phenological series, and we compare them with those of similar European series. We show the evolution trends for different observed species, such as almond tree (Prunus dulcis), hazel (Corylus avellana), plum (Prunus domestica), olive tree (Olea europea), apple tree (Malus domestica) or vineyard (Vitis vinifera).

The results showed that 219 fires were recorded, burning 415,572.50 ha. In the average, 10.43 fires occurred per year, resulting in 19,789.17 ha burned. Incendiaries caused largest fires regarding the affected area, followed by fires caused by debris burning and lighting, that is first in number of occurrences. Fires caused by incendiaries and the unknown causes were more frequent in August and September. Fires caused by lightings occurred mainly in October and February, and those associated to debris burning were concentrated in the month of July. The largest fires occurred in areas with steep slopes, while the fires smaller than 4.0 ha, occurred in flat or smooth areas. Most of fires that occurred during the study period burned up to 200.000 ha and the larger fires occurred in the park region where the IBAMA (Instituto Brasileiro do Meio Ambiente e do Desenvolvimento Sustentável already has the ownership or land control. These fires were possibly caused by incendiaries.

Respecto a la época, se lo ubica en el llamado “Periodo de Desarrollos Regionales” entre los años 900 y 1430 después de Cristo. Se discute sobre si es posible extender lo consignado por ciertos cronistas mestizos y españoles (Poma de Ayala y Cieza de León a la interpretación de este motivo. Estas Crónicas de la Conquista hablan de una época preincaica de conflicto interétnico permanente o Edad de los Auca Runa. Se plantea si el motivo tiene igual presencia que las imágenes de caravanas que también se dan en este periodo y se alude a la tradición oral para dirimir la cuestión.ABSTRACT: This article deals with the motif (or theme of war and weapons in the rock art of the andean provinces of Argentina. This motif appears repeatedly during the Regional Developments Period (900-1430 AD. It is interesting to discuss the possible extension of the so called “Warriors Era” of the Spanish Chroniclers in Perú (Poma de Ayala and Cieza de León to the interpretation of this motif. These Chronicles speak about a Pre-Inka Era characterized by unrest and confrontation among andean groups. At the same region and period the motif of lama caravans increase its importance. Oral tradition is decisive to adopt or to reject the peruvian model.

    Full Text Available De un tiempo a esta parte, los estudios de género en arqueología han tomado relevancia dentro de la arqueología mundial (ver Gero y Conkey 1991; Brumfield 1996; Escoriza Mateu 2002; entre otros. En nuestro país, sin embargo, este tópico ha sido prácticamente inexplorado. Este trabajo propone analizar la manera en que fueron representadas las relaciones de género en un sitio del Valle Calchaquí Norte durante el Período Tardío -900/1470 DC- (Tarragó 1974. Partiendo del estudio de los grabados rupestres del sitio Los Cerrillos y tomando como objeto de análisis sólo las representaciones antropomorfas presentes, se avanzará en el conocimiento acerca de cómo eran producidas y reproducidas las relaciones de género a través de la narrativa manifiesta en el arte rupestre de Los Cerrillos. Del análisis realizado se concluye que las representaciones de las figuras femeninas y masculinas son cuantitativamente diferentes, representando esto un discurso explícito en donde se resaltan las diferencias sociales de cada género.

    Seven biostratigraphic intervals have been identified through biostratigraphic studies based on calcareous nannofossils from samples of the Quaternary section of Campos and Santos basins. These intervals (named A to G) are based mainly on biological events such as extinction, first appearance, and prevalence (acme zone) of cosmopolitan taxa. In view of this, almost all recognized sections have an identity with colval biozones that have been described in the bibliography, making easier their correlation with magneto stratigraphic units and the inference of absolute ages. Nevertheless, interval D has not been consistently identified. According to what was observed it is possible to further divide the section. Such detailing would be based mainly on the appearance of Helicosphaera inversa (in interval C) and form B of H. carteri. var. wallichii (at the base of interval F), and on the abundance of H. carteri s.l. (in interval G). It is possible that other subdivisions will be delineated through quantitative investigation. However, these would be based on `anomalous` concentrations of some species with strong environmental connotation. This is the case, for example, of sharp variations in the absolute frequency of Coccolithus pelagicus which, for the time being, have been detected in intervals F and G. According to the bibliography, this species attains maximum proliferation during glacial epochs. (author). 5 figs., 1 tab.

    Full Text Available The Campina Grande and Serra Redonda Granites are intrusive along the contact of the Paleoproterozoic basement(Alto Moxotó Domain with the Tonian gneisses (Alto Pajeú Domain of the Borborema Province (northeast Brazil. TheCampina Grande Granite (U-Pb age = 581± 2 Ma shows a concentric oval-shaped structure whereas the Serra RedondaGranite (U-Pb age = 576 ± 3 Ma has a tabular shape, elongated in the NE-SW direction. The plutons are separated bythe left-lateral Galante transcurrent shear zone. In this study, the anisotropy of magnetic susceptibility (AMS was appliedto 64 outcrops of granites to determine the internal structures of these plutons and to explore the relationship betweenmagmatism and deformation in an orogenic setting. The magnetic fabrics are concordant with the metamorphic structure ofthe host rocks. Strike-slip shear zones controlled the emplacement of the Serra Redonda Granite, as indicated by sigmoidalfoliation, defining shear bands associated with the Galante shear zone. In contrast, the magmatic/magnetic fabric of theCampina Grande granite seems to have been produced by body (ascensional forces. The pluton displays an inward dipping, concentric planar fabric parallel to the wall rock contact and lineations highly oblique to the foliation trend. The fabric of the Campina Grande pluton is consistent with a magma moving over a ramp dipping to southwest, with the lineation at high angle to the NE-trending flow direction. The contrasting structures of the plutons reflect the episodic nature of orogenic deformation, which was punctuated by the alternation of weak and strong strains, affecting the fabric development of the syntectonic intrusions.

  9. Rb/Sr geochronology in whole rocks and minerals of the Cumaru granodiorite, Serra dos Gradaus, Para state, Brazil

    International Nuclear Information System (INIS)

    The Cumaru granodiorite occurs in the Serra dos Gradaus region, southeastern part of the Metallogenic Province of Carajas, Para. Rb-Sr systematics have been provided in whole rocks and minerals for samples of the Cumaru granodiorite thus an age of 2543 ± 53 Ma, with an initial isotopic ratio of 0.70311 ± 34 (MSWD+1.87) was obtained for whole rocks samples. Taking in account that these rocks are not affected by metamorphism and/or deformation, we consider the age of 2543 ± 53 Ma as an emplacement age corresponding to the crystallization of the body. Such an age confirms the existence of a late Archaean plutonic event in the Serra dos Gradaus area and the interpretation of the Cumaru granodiorite as a contemporaneous and cogenetic body of the Juruena type granites (Ca. 2000 Ma old), as proposed previously, must be definitively abandoned. Therefore, Archaean ages for the greenstone belt sequence (Gradaus group) as well as for the Xingu complex in this area are also confirmed, although by indirect evidence. The age obtained implies that the latter represents an Archaean metamorphic basement in the Serra dos Gradaus region rather than the reworking of the late archaean granitics rocks during the Transmazonian orogenic event. The initial isotopic ratio of 0.70311 ± 34 is close to a mantellic or low time of crustal residence source material ratios at the end of Archaean times. Therefore, comparison with isotopic initial ratios of other granitic rocks which occur in the Rio Maria region identifies an evolution line with a Rb-Sr ratio of 0.25 for a crustal source material that would have separated from mantle about 2.8 Ga ago.

    Full Text Available In the southern escarpment of the Serra da Mantiqueira, northeast geographic divider between the State of São Paulo and Minas Gerais, there was an environmental accident caused by the disruption of an adductor whose purpose is to lead the water from a reservoir located at an altitude of 1820 m to the machine house where there is an electric generator located at 750 m.  This accident resulted in the formation of a scar on the hillside forest, with removal of soil and vegetation. To reverse the erosion processes, a methodology was developed consisting of the use of four barriers (numbered I to IV formed by seedlings of Bambusa mutiplex (Lour., whose purpose was to divert the water runoff in order to provide the regeneration of native vegetation. Stalks of bamboo intercropped with Bambusa multiplex were used to contain debris in two gullies formed by erosion. The development of vegetation was monitored for 18 months and evaluated by the application of a Leopold Matrix composed of 5 points, which are: erosion, regeneration of vegetation, success of bamboo planting, installed conservation structures and functionality. The purpose of the matrix was to demonstrate the effectiveness of interventions using bamboo. The result of the classification matrix enabled the quantitative and qualitative classification of the interventions, resulting in five levels, where the barriers I, II and IV were considered to be of very high efficiency, and barrier III was considered to be of high efficiency. The contention of the gully was considered to be of medium to very high efficiency.

The main reasons for its introduction in Brazilian rivers have been the increase in and Rio Macae (RJ in 1952. Currently, the species can now be found in all the states of the South sport fishing and tourism, often on the grounds of alleged lack of other species of fish in the rivers, as happened for example in Sierra Santa Catarina. More recently the Law nº1098 by prohibiting the creation of exotic species in Brazilian rivers included the trout which was later also excluded from this relationship that allowed the creation of this kind continue to occur. Although historically trout has been introduced by government initiative, and the legislation has been lenient, the main supporters of this activity, now are businessmen in the tourist industry and anglers. The trout farming has also been practiced for sale of live specimens, without obtaining the environmental license. Restrictive environmental standards are very recent and little publicized. Impact assessment studies on the native fauna to support educational campaigns and to propose measures for handling and marketing Trout are recommended actions.

    Full Text Available We inventoried the birds from Serra do Aracá region, state of Amazonas. The region encompasses a high diversity of vegetation types, including white sand forests and campinas, terra firme and flooded forests, montane forests and tepuis. We recorded 416 bird taxa in 69 families through captures with mist nets, tape recording of bird voices, and collection of voucher specimens. A large proportion of them (61% were recorded in a single vegetation type. Qualitative estimates suggest that approximately 580 bird species occur in the region. The avifauna of the Aracá region has a mixed biogeographic composition, with species typical of both margins of the Rio Negro occurring sympatrically. Additionally, species whose distributions are restricted to three areas of endemism for Amazonian birds (Imeri, Guiana and Pantepui were recorded in the region. Rare landscapes in the Brazilian Amazon are found in the Serra do Aracá region. Additionally, we recorded endemic and rare birds, highlighting the value of the region for conservation. The Serra do Aracá State Park officially protects montane forests, terra firme forests and tepuis. We suggest that the large extension of white sand campinas and igapó forests at the southern portion of Serra do Aracá should be also preserved in order to improve the representation of the rich natural heritage of the region.

  8. Helping enhances productivity in campo flicker ( Colaptes campestris) cooperative groups

    Dias, Raphael Igor; Webster, Michael S.; Macedo, Regina H.

    2015-06-01

    Reproductive adults in many bird species are assisted by non-breeding auxiliary helpers at the nest, yet the impact of auxiliaries on reproduction is variable and not always obvious. In this study, we tested Hamilton's rule and evaluated the effect of auxiliaries on productivity in the facultative cooperative breeder campo flicker ( Colaptes campestris campestris). Campo flickers have a variable mating system, with some groups having auxiliaries and others lacking them (i.e., unassisted pairs). Most auxiliaries are closely related to the breeding pair (primary auxiliaries), but some auxiliaries (secondary auxiliaries) are unrelated females that joined established groups. We found no effect of breeder quality (body condition) or territory quality (food availability) on group productivity, but the presence of auxiliaries increased the number of fledglings produced relative to unassisted pairs. Nonetheless, the indirect benefit of helping was small and did not outweigh the costs of delayed breeding and so seemed insufficient to explain the evolution of cooperative breeding in campo flickers. We concluded that some ecological constraints must limit dispersal or independent breeding, making staying in the group a "best-of-a-bad-job" situation for auxiliaries.

  9. Changing collecting strategies of the clam Donax serra Röding (Bivalvia: Donacidae) during the Pleistocene at Pinnacle Point, South Africa.

    2014-03-01

    South Africa's Middle Stone Age (MSA) coastal sites have played a prominent role in documenting early evidence of systematic shellfish collection and adaptation to aquatic environments in the context of anatomically modern humans. Pinnacle Point 13B cave is important among these MSA sites not only because it holds the earliest yet known evidence for human use of marine resources (∼162 ka [thousands of years ago]), but because shellfish observations have been integrated more fully into discussions of MSA adaptations. This is particularly the case of Donax serra procurement on sandy beaches, where skills that are usually indicative of an aspect of behavioural modernity (in the context of hunting) were apparently used. In this paper, D. serra from 110 to 91 ka old assemblages are studied in detail by way of metrical analyses and relevant biological and ecological literature of this species. Existing seasonality studies derived from oxygen isotope analyses on the same molluscs are incorporated into this reconstruction. Shellfish appear to have been collected in winter over many millennia when D. serra are most nutritious due to high gonad content. A dramatic change in collection strategies took place during the same millennia-long period. Earliest systematic collection of D. serra consisted of mostly unselective procurement of animals in terms of shell size along the tidal gradient and beach depth. In later visits, people collected mostly larger individuals by narrowing their collection to the mid-intertidal. This change increased the efficiency of D. serra collection, which reflects a positive adaptive behaviour that endured into Later Stone Age (LSA) times.

  10. Ore mineralogy of the Serra Pelada Au-Pd-Pt deposit, Carajás, Brazil and implications for ore-forming processes

    2016-08-01

    Serra Pelada is a world-class hydrothermal Au-Pd-Pt deposit located at the eastern border of the Amazon craton, northern Brazil. The rocks at Serra Pelada have experienced intense tropical weathering for about 70 Ma, but drill core samples preserve the primary mineralogy and hydrothermal alteration features, with extreme grades of Au, Pd and Pt individually reaching hundreds of parts per million (ppm) by weight. Mineralization at Serra Pelada occurs in hydrothermally altered metasiltstones and dolomitic metasandstones at the hinge zone of a recumbent syncline, comprising zones of hematite, chlorite-carbon, argillic, and siliceous alteration. The main hydrothermal gangue minerals are quartz, kaolinite, sericite, amesite, hematite, monazite, florencite and variable amounts of highly reflective carbonaceous matter. Hydrothermal carbon input is evident from precipitated carbon occurring along crenulation planes and veinlets associated with the precious metals. Ore and accessory minerals include a variety of sulphide, selenide, arsenide, sulphate and oxide minerals, including gold with variable metal contents, palladian gold, fischesserite, sudovikovite, sperrylite, selenian braggite, isomertieite, mertieite-II and secondary Au-Pt-Pd alloys. The composition of fischesserite varies from the ideal formula (Ag3AuSe2) towards a more Ag-rich composition, indicating a disordered solid solution form that is stable only above 260 °C, consistent with the high thermal maturity of associated carbonaceous matter approaching graphite. Primary ore and gangue minerals at Serra Pelada comprise a suite of elements that are best transported in oxidising conditions and precipitated upon reduction. This suggests that fluid mixing between a highly oxidised (metal carrier) and a reduced fluid was a key process for high-grade noble metal precipitation at Serra Pelada.

    El proyecto de instrumentación de mayor importancia que ha tenido el Instituto de Astrofisica de Canarias en los últimos afios ha sido el diseflo y construcción del te1escopio IAC8O. Este requería del esfuerzo con junto en mec´nica, óptica y electrónica, lo que facilitó la estructuración y el crecimiento de los respectivos grupos de trabajo, que posteriormente se integraron en departamentos En su origen (1977), el telescopio IAC80 fue concebido como un sistema clásico tipo Cassegrain, con una razón focal F/i 1.3 para el sistema Casse grain y una razón focal F/20 para el sistema Coudé. Posteriormente, aunque se mantuvo la filosofia de que el sistema básico fuera el F/11.3, se consideró conveniente el diseño de secundarios para razones focales F/16 y F/32, y se eliminó el de F/20. Sin embargo, dada la importancia relativa que un foco estrictamente fotográfico tiene en un telescopio moderno, diseñado básicamente para fotometría fotoeléctrica y con un campo util mínimamente de 40 minutos de arco, se decídió Ilevar a cabo el diseño de un secundario F/8 con un sistema corrector de campo, pero que estuviera formado únicamente por lentes con superficies esféricas para que asl su construcción fuera posible en España ó en México. La creciente utilización de detectores bidimensionales para fines de investigación astron6mica y la viabilidad de que en un futuro cercano éstos tengan un área sensible cada vez mayor, hicieron atractiva la idea de tener diseñado un sistema corrector de campo para el foco primario (F/3), con un campo útil mínimo de un grado, y también con la limitante de que sus componentes tuvieron sólamente supérficies esféricas. Ambos diseños de los sis-temas correctores de campo se llevaron a cabo, en gran medida, como parte de un proyecto de colaboración e intercambio en el área de diseño y evaluación de sistemas ópticos.

    Created at 1977, the Parque Estadual da Serra do Mar - PESM is managed by Fundacao Florestal of Sao Paulo - FF and it covers mores than twenty cities between the coast and the plateau. In the 1950 and 1960 years PETROBRAS had its industrial plants installed, specially the pipeways, from coast to plateau. These installations suffered the interference of the PESM and because of this turned to constitute a conflict zone using. As a strategy to solve conflicts and to prospects tendencies of management that can influence on the maintenance and eventual amplifying of pipelines and other installations, the Company passed to integrate the management councils of the PESM. This recent experience has appointed to good results, especially by the opportunity to expand the Company involvement in the social and environmental issues, in cooperation with public sector on conservation area, maintaining direct relation with sustainable development.

    In this work, results on studies carried out on radioactive samples from Serra do Sossego (close to Carajas , in the state of Para) are reported. According to studies of mineralogical characterization, involving petrographic and mineralographic analysis, complemented by other specific techniques, it was possible to determine the forms of presentation of the uraninite (UO{sub 2}), and its respective association to sulphide minerals rich in copper, primarily those with greater concentration, such as bornite (Cu{sub 5}FeS{sub 4}) and, secondarily, calcopirite (CuFeS{sub 2}). These sulphides come associated to abundant iron oxide, such as magnetite (Fe{sub 3}O{sub 4}) and its alteration products, and also assorted silicate minerals. From the results of autoradiographic tests and an electronic microprobe, a significant amount of uraninite was determined, showing that sulfites and oxides that occur associated to the uranium mineral, include this element in their crystalline lattices.

The results showed that the extraction rate was maximum when 70%methanol was as solvent and microwave method was better than water bathing. Dracocephalum rupestre could adsorb heavy metals nickel and copper ions under the condition of simulating tea drinking condition. The adsorbtion to Ni 2+and Cu2+was endothermic and elevated temperature was advantaged. The adsorbtion isotherms of both ions were fitted to a Langmuir equation, which means the adsorption is monodermic. The maximum number of adsorbed metal ions was given:50.25 mg/g for Ni2+and 57.47 mg/g for Cu2+.

    Results of apatite and zircon fission track analysis of samples from the Serra de Santana mesa provide quantitative constraints on the depositional age of the nonfossiliferous Serra do Martins Formation. This unit consists of sedimentary remnants preserved at high elevations on the Borborema Plateau and its distributions and age are considered important in understanding the geomorphological evolution and denudation history of northeastern Brazil following the early Cretaceous breakup. We also report apatite fission track results from post-rift units of the Potiguar Basin (Acu and Tibau formations). Apatite fission track analysis (AFTA) of samples from the Serra do Martins Formation suggests that they reached maximum paleotemperatures around 60 deg C, from which they began to cool some time between 30 and 0 Ma. Due to the high thermal gradients related to the prolonged Cenozoic volcanism in the study area, we hypothesize that the paleotemperatures modeled for those samples may be related dominantly to an anomalous heat flow, rather than to significant burial. Zircon fission track analysis (ZFTA) in two samples of the Serra do Martins Formation yields ages of 135 {+-}18 Ma and 165{+-}40 Ma, but both samples show a significant spread in the data, and the youngest population of grains in these samples are characterized by ages of 83{+-} Ma and 65{+-} Ma, respectively. As the AFTA data show that these ages have not been reset after deposition, the zircon fission track ages must represent inherited provenance ages, demonstrating that those sediments can be no older than Paleocene. Independent lithological observations provide additional support to reject a stratigraphic correlation between the Serra do Martins and Acu formations. Combining the AFTA and ZFTA results, and integrating available geological evidence, we suggest that the Serra do Martins Formation was deposited some time between 64 and 25 Ma (Paleocene-Oligocene).

    Chestnut flowers, lemon balm plants and their decoctions were incorporated into "Serra da Estrela" cheese, to assess their potential to preserve its nutritional properties and provide new foodstuffs. The analyses were carried out after the normal ripening period of 1month and after 6months of storage. The most abundant nutrients were proteins and fats. The most abundant minerals were Ca and Na, while C16:0 and C18:1 were the main fatty acids. Saturated fatty acids were the most abundant, followed by the monounsaturated. Moisture seemed to be lower in the samples with the plants incorporated. The dried plants, when incorporated, seemed to be more efficient as preservers then the decoctions, although these better preserved the proteins. These plants can be regarded as promising natural preservers in foodstuffs cheese, given the preservation of key parameters and the slight impact on the nutritional value. PMID:26988492

    Full Text Available Abstract: Aim The goal of this study is to examine the composition and richness of caddisfly assemblages in streams at the Serra da Bocaina Mountains, Southeastern Brazil, and to identify the main environmental variables, affecting caddisfly assemblages at the streams with different conditions of land use. Methods The sampling was conducted in 19 streams during September and October 2007. All sites were characterized physiographically by application of environmental assessment protocol to Atlantic Forest streams and by some physical and chemical parameters. Of the 19 streams sampled, six were classified as reference, six streams as intermediate (moderate anthropic impact and seven streams as poor (strong anthropic impact. In each site, a multi-habitat sampling was taken with a kick sampler net. The sample was composed by 20 units, each one corresponded to 1 m2 of collected substrate, corresponding 20 m2 of sampling area. The material was placed in a plastic container (500 µm of mesh, washed, homogenized and sub-sampled. For each stream, 6 subsamples were randomly sorted. Results Were collected 2,113 caddisfly larvae, belonging to 12 families and 28 genera. Hydropsychidae and Leptoceridae were the most abundant families, and Smicridea was the most abundant genus. Sorensen’s index results showed that the streams studied were grouped according to environmental integrity. The Indicator Species Analysis showed only characteristic taxa to reference streams. Canonical Correspondence Analysis showed that caddisfly assemblage was strongly influenced by nitrate concentration, pH and condition of riparian vegetation. Multiple regression analysis indicated significant correlations to five genera with some environmental parameters, besides total abundance of Trichoptera. Conclusions Ours results showed that degree of environmental impact, mainly the nitrate concentration, pH, and condition of cover vegetation acted as a major factor in determining the

    The petroleum systems of the Campos Basin contains 60 billion barrels of discovered oil in place and 775 billion cubic meters of natural total gas in place, comprising one of the most prolific petroleum systems in South America . It is located in southeast Brazil covering about 100,000 km{sup 2} with 44 oil fields, seven giants, holding up to 90% of total Brazilian oil reserves and 50% of total natural gas reserves. The Campos Basin produces mostly from turbiditic sandstones of the Carapebus formation (Cretaceous-Tertiary), comprising the biggest part of the total production. Other important reservoirs are calcarenites of the Macae formation (Albian), bioclastic lacustrine limestones of the Lagoa Feia formation (Barremian), and fractured basalts of the Cabiunas formation (Neocomian). The source rocks are saline-to-brackish lacustrine water of the Lagoa Feia formation (Barremian) containing 5% TOC average, an average thickness about 100 m with a maximum of 500 m in depocenters, covering approximately 50,000 km{sup 2}. Trapping style is chiefly structural for the Cabiunas formation; structural-stratigraphic for the coquinas (bioclastic limestones of the Lagoa Feia formation), where pinch-out of the coquinas is a common feature; strongly structural for the calcarenites of the Macae formation (rollovers related to salt tectonics), and finally structural combined with sandstone pinch-out for the Cretaceous and Tertiary turbidites of the Carapebus formation. At the Corvina-Parati depo center, thermal basin modeling suggests the onset of oil generation in late Albian, reaching its maximum during the Miocene and it is still going on to present days. The top of oil window is about 4,5000 m deep and transformation rate reaches up to 70%. Seismically, the Campos Basin shows distinct response and characteristics according to lithologies and ages. The lowermost sequence (Lagoa Feia and Cabiunas formations) is poor in seismic attributes; the geological model is more adequate for

Los espasmos y catarros en vías aéreas superiores fueron las afecciones más frecuentes en la población de Campo Quijano. En rinitis no se encontraron diferencias entre barrios. El barrio San Roque presentó las mayores prevalencias en CVAs, espasmos y tos irritativa. Barrios cercanos a las borateras presentaron prevalencias dispares, lo que podría relacionarse con características socio-culturales, sanitarias y económicas, entre otros factores de riesgo, no considerados en este diagnóstico.

    Full Text Available El autor propone que existe una serie de creencias y prácticas tradicionales que pueden proporcionar pistas acerca de la interacción de campos electromagnéticos en la biosfera. Por ejemplo, la creencia en el mal de ojo puede ser una construcción cultural relacionada con la sensación de estar siendo observado, pero a su vez puede estar basada en las emisiones de ondas electromagnéticas a través de los ojos. En este artículo se presentan datos para apoyar esta hipótesis. Otras creencias tradicionales, como la importancia de la conexión con la Madre Tierra también pueden contener una explicación similar. En este artículo se presentan una serie de hipótesis científicamente verificables sobre creencias tradicionales y campos electromagnéticos. En esta fase, los datos son insuficientes para confirmar la hipótesis, no obstante el objetivo de este artículo es estimular el pensamiento crítico y la investigación sobre algunas creencias tradicionales.

    Serra da Estrela Protected Designation of Origin (PDO) cheese is the most famous Portuguese cheese and has a high commercial value. However, the adulteration of production with cheaper/lower-quality milks from non-autochthones ovine breeds compromises the quality of the final product and undervalues the original PDO cheese. A Randomly Amplified Polymorphic DNA (RAPD) method was developed for efficient detection of adulterant breeds in milk mixtures used for fraudulent production of this cheese. Furthermore, Sequence Characterized Amplified Region (SCAR) markers were designed envisioning the detection of milk adulteration in processed dairy foods. The RAPD-SCAR technique is here described, for the first time, to be potentially useful for detection of milk origin in dairy products. In this sense, our findings will play an important role on the valorization of Serra da Estrela cheese, as well as on other high-quality dairy products prone to adulteration, contributing to the further development of the dairy industry.

    The Macae Formation (Late Albian-Turonian of the Campos Basin) is represented by a thick column of carbonate sediments whose deposition began soon after the evaporitic phase that marks the beginning of the marine occupation of the basin. The top of this interval is represented by an unconformity (Type I), indicative of a variation in the base level of the basin, on which the turbidities of the basal sequence of the Namorado Field were deposited. For a better understanding of the depositional geometry of these turbidities, the paleogeomorphology analysis demonstrated to be quite efficient. The method of work used for so was a combination among the seismic 3D visualization (VoxelGeo{sup R}), from the characterization of different physical attributes of the seismic signal, and the facies analysis of wells profiles of the referred field. The developed analysis allowed the individualization and the three-dimensional visualization of a sinuous paleochannel in the top of the interval, until then not described in previous interpretations of this depositional system. With the information coming from this study, a better understanding of the genesis of this accumulation can be reached, especially in the part regarding to the units of important economic character, represented by the turbidities deposits and whose occurrences are related with stages of relative lowering of the sea level.

    One of the fundamental problems to understanding the evolution of volcano-sedimentary sequences in southeastern Brazil is constraining their depositional ages. Brasiliano tectonic and metamorphic either obscured or destroyed primary features, such as unconformities, as well as other geologic relationships. This problem is exemplified by the Serra do Itaberaba and Sao Roque groups, where the lack of data about the timing of their deposition has prevented resolution of proposed one-and two-stage geotectonic/depositional models. Recent U-Pb zircon data obtained from metavolcanic rocks in the Sao Roque Group indicate that it was deposited between 628 and 607 Ma. New U-Pb zircon data of 1395{+-} 10 Ma for a metandesite in the basal Morro da Pedra Preta Formation (Serra do Itaberaba Group) indicate the maximum age for the beginning of the deposition of the pelites overlying MORB-like basalt. A metarhyolite of the upper unit, the Nhangucu Formation, contains two zircon populations. One yielded an age of 619 {+-}3 Ma, which defines the crystallization age of the rock, and the other an age of 1449 {+-}3 Ma, interpreted as inherited xenocrystal grains from older units of the Serra do Itaberaba Group. The younger metarhyolite was affected only by the S{sub 2} foliation, generated during the Brasiliano orogenesis, whereas the Middle Proterozoic metavolcano-sedimentary sequence records additional metamorphic and deformational events, confirming the presence of two different geotectonic cycles.

  16. Temperature effect correction for the cosmic ray muon data observed at the Brazilian Southern Space Observatory in São Martinho da Serra

    International Nuclear Information System (INIS)

    The negative atmospheric temperature effect observed in the muon intensity measured by surface-level detectors is related to the atmospheric expansion during summer periods. According the first explanation given, the path of muons from the higher atmospheric level (where they are generated) to the ground becomes longer, and more muons decay, leading to a muon intensity decrease. A significant negative correlation, therefore, is expected between the altitude of the equi-pressure surface and the muon intensity. We compared measurements of the altitude of 100 hPa equi-pressure surface and data from the multidirectional muon detector installed at the Brazilian Southern Space Observatory in São Martinho da Serra, RS. Significant correlation coefficient were found (up to 0.95) when using data observed in 2008. For comparison, data from the multidirectional muon detector of Nagoya, located in the opposite hemisphere, is studied and an anti-phase in the cosmic ray variation related with the temperature effect is expected between data from detectors of Nagoya and São Martinho da Serra. The temperature influence is higher for the directional channels of Nagoya than for ones of São Martinho da Serra.

    The Serra da Canastra region, located in southwestern Minas Gerais, Brazil, is recognized worldwide for its tradition of producing artisanal cheeses. However, as production is done by hand, great variability exists in the characteristics of artisanal Minas cheese. Thus, it is important to characterize the sensory profile of these products and verify the quality attributes that lead to their acceptance. Therefore, this study aimed to characterize the dynamic sensorial profile of artisanal Minas cheese produced in the Serra da Canastra region through temporal dominance of sensations and sensory acceptance tests and verify the attributes that lead to product quality. We observed that the texture and flavor profile varied among the evaluated artisanal Minas cheeses from Serra da Canastra, some cheeses being more characterized by creamy and soft or hard and firm sensations, whereas others had high dominance rates for crumbly texture. In relation to flavor, salty and bitter tastes were dominant in most cheeses, some also being characterized by a sour taste, and others by buttery and rancid attributes, which indicates a lack of product standardization. However, all samples obtained scores between 6 (liked slightly) and 7 (liked moderately), indicating good acceptability in relation to the texture and flavor of the evaluated cheeses. Moreover, it is possible to infer that creamy and soft or hard and firm are positive attributes for cheese texture, and bitter, buttery, salty, and acid taste drive cheese acceptance. This study provides important information for product standardization, quality improvement, and process origin indications, besides providing quality attributes that meet consumer desires.

Its complex structure has been possible to characterize, not only due to excellent outcrop condition (mostly induced by the competent behaviour of the Lower Ordovician Armorican Quartzite Formation), but also to the detailed lithostratigraphic control of the Ordovician-Silurian lithologies. These units are present in a homogeneous regional distribution, unconformably overlain the Cambrian Beiras Group. Concerning the Variscan structures, their geometry and kinematics show that they could be ascribed to progressive deformation induced by the first and main D1 tectonic event. During this event, a complex NNW-SSE aggregation of fold and thrust arrays have been developed. At the macroscale, this pattern is mainly characterized by the Serra de Moradal-Fajão syncline. Both limbs of this major D1 Variscan fold, which present a slightly ENE facing, have been disrupted by convergent thrust systems, leading to the superposition of the Cambrian Beiras metasediments on top of the Ordovician-Silurian succession. Concerning its SW limb, a major single overthrust has been developed, the Vilar Barroco-Fajão one, although in some very localized sectors, some minor thrusts could be emphasized; as they present a ENE facing, they are interpreted as duplex style forethrusts in relation to the main overthrust. Regarding the NE limb, a different behaviour is found. Indeed, in this sector, an imbricated thrust system has been mapped; due to their WSW facing it should be considered as backthrusts. Concerning the temporal relations between the previously described structures, although in some rare cases backthrusts cut forethrusts, the scarcity of

    Full Text Available The geochemical characterization of thirteen Serra Geral Group flows in the Vista Alegre region (RS-SC, southern Brazil, displays the homogeneous basaltic composition near 50 wt.% SiO2. Each of the five basal flows (Pitanga-type, high-Ti/Y ~600, TiO2 > 3 wt.% and eight upper flows (Paranapanema-type, medium Ti/Y ~400, TiO2 > 2 wt.% can be identified from their chemical composition; sets of flows have parallel variation in chemical composition. The flow-by-flowcorrelation in four sections shows the horizontal position of the flows in three profiles and an approximately 200-m downdrop of the Itapiranga block with respect to the Frederico Westphalen block. The world-class amethyst geode mineralization and the systematic presence of native copper in the basalts make the correlation of great geological and economic significance.A caracterização geoquímica de treze derrames do Grupo Serra Geral na região de Vista Alegre (RS e SC, sul do Brasil, exibe uma composição basáltica homogênea próxima a 50% de SiO2. Os cinco derrames basais são classificados quimicamente como tipo Pitanga (alto Ti/Y ~600 e TiO2 > 3 em peso percentual, os demais oito derrames possuem médio Ti/Y ~400 com TiO2 ~2.5 em peso percentual, sendo classificados como magma tipo Paranapanema. Cada derrame pode ser identificado através de sua composição química e correlacionado, com variação paralela entre os perfis estudados. A correlação derrame a derrame nos quatro perfis demonstra uma posição horizontal em três perfis e um rejeito vertical de aproximadamente 200 m do bloco Itapiranga em relação ao bloco Frederico Westphalen. A presença de jazidas de ametista em geodos e a sistemática ocorrência de cobre nativo nos basaltos da região tornam a correlação de grande significado geológico e econômico.

    Full Text Available Peatlands are soil environments that store carbon and large amounts of water, due to their composition (90 % water, low hydraulic conductivity and a sponge-like behavior. It is estimated that peat bogs cover approximately 4.2 % of the Earth's surface and stock 28.4 % of the soil carbon of the planet. Approximately 612 000 ha of peatlands have been mapped in Brazil, but the peat bogs in the Serra do Espinhaço Meridional (SdEM were not included. The objective of this study was to map the peat bogs of the northern part of the SdEM and estimate the organic matter pools and water volume they stock. The peat bogs were pre-identified and mapped by GIS and remote sensing techniques, using ArcGIS 9.3, ENVI 4.5 and GPS Track Maker Pro software and the maps validated in the field. Six peat bogs were mapped in detail (1:20,000 and 1:5,000 by transects spaced 100 m and each transect were determined every 20 m, the UTM (Universal Transverse Mercator coordinates, depth and samples collected for characterization and determination of organic matter, according to the Brazilian System of Soil Classification. In the northern part of SdEM, 14,287.55 ha of peatlands were mapped, distributed over 1,180,109 ha, representing 1.2 % of the total area. These peatlands have an average volume of 170,021,845.00 m³ and stock 6,120,167 t (428.36 t ha-1 of organic matter and 142,138,262 m³ (9,948 m³ ha-1 of water. In the peat bogs of the Serra do Espinhaço Meridional, advanced stages of decomposing (sapric organic matter predominate, followed by the intermediate stage (hemic. The vertical growth rate of the peatlands ranged between 0.04 and 0.43 mm year-1, while the carbon accumulation rate varied between 6.59 and 37.66 g m-2 year-1. The peat bogs of the SdEM contain the headwaters of important water bodies in the basins of the Jequitinhonha and San Francisco Rivers and store large amounts of organic carbon and water, which is the reason why the protection and preservation

    Apesar da astronomia ser um dos temas indicados pelos Parâmetros Curriculares Nacionais, observa-se que poucas mudanças ocorreram desde a implementação do mesmo em sala de aula. A presente pesquisa diz respeito sobre como os tópicos de astronomia estão sendo abordados pelos professores no ensino médio. Optou-se por aplicar um questionário com os professores que ministram a disciplina de física. Os mesmos trabalham em escolas estaduais situadas nas cidades de Ribeirão Pires e Rio Grande da Serra, ambas subordinadas a Diretoria de Ensino de Mauá, no Estado de São Paulo. O questionário foi aplicado durante o 2° semestre de 2006. Até o momento os resultados são preliminares. Dos 82,0% dos professores que responderam ao questionário no município de Rio Grande da Serra, 66,7% não aplicaram nenhum tópico de astronomia, 77,8% não utilizaram qualquer tipo de programa computacional, 66,7% não utilizaram laboratório, que 77,8% nunca levaram os alunos a museus e ou planetários e que 66,7% não indicaram qualquer tipo de revista ou livro sobre astronomia aos seus alunos. No município de Ribeirão Pires, 53,3% dos professores responderam ao questionário, destes 75,0% não aplicaram nenhum tópico de astronomia, 93,8% não utilizaram qualquer tipo de programa computacional, 75,0% não utilizaram laboratório, 81,3% nunca levaram os alunos a museus e ou planetário e 56,3% não indicaram qualquer tipo de revista ou livro sobre astronomia ao seus alunos. Apesar da maioria dos professores reconhecerem que o conteúdo de astronomia influi na formação do jovem, os mesmos não incluem o tema em seus planejamentos escolares.

    Full Text Available Analogue experiments were carried out to get insights into the processes governing positive inversion during the foreland propagating thrust tectonics in the southern Serra do Espinhaço, a Brasiliano/Panafrican foldthrust belt in southeast Brazil. In particular, model listric half-grabens were inverted by applying contractional displacement to the footwall blocks. We investigated two different inversion conditions in listric half-grabens: (i extensional and contractional detachments at the same level and (ii at different positions. The models revealed that the development of a forward-breaking thrust system occurs in the basin synrift deposits, by contractional translation of the extensional footwall block when the extensional and contractional master faults do not coincide. Our experiments show the tectonic imbrication between basement and synrift sequences which characterizes the southern Serra do Espinhaço, and support the location in the eastern mountain range domain of the Espinhaço rift master fault system, which is not exposed at the surface.Em experimentos de areia foi simulada a inversão positiva com o intuito de investigar os processos que governam a tectônica da Cordilheira do Espinhaço Meridional na borda sudeste do Cráton São Francisco. Analisou-se, em particular, a evolução progressiva de hemigrabens, com falha de borda lístrica, na qual o fechamento da bacia ocorreu através da translação do bloco do muro da falha mestra. Duas condições foram investigadas: (i os descolamentos distensivos e compressivos ocorrem na mesma cota e (ii os descolamentos situam-se em posições diferentes. Os modelos revelaram que um sistema de falhas de cavalgamento com estilo colapso da lapa se desenvolve no interior do depósito sinrift quando os descolamentos não coincidem. O imbricamento entre escamas do pré- e sinrift, nos modelos, permite esboçar uma analogia com a tectônica da porção sul da Cordilheira do Espinhaço e situar a

    The analysis of trace elements such as rare earths, Th, U, Ta, Hf, Ba, Rb and Ba, is a very important tool for petrogenetic studies. In order to study these processes in dykes of Enxame Serra do Mar (Coast of Sao Paulo and Rio de Janeiro), belonging to the Parana Magmatic Province (PMP), one of the most significant provinces of continental basalts in the world, were perform analyzes by neutron activation in these dikes. The technique, employed in Centro de Reator de Pesquisa of the Instituto de Pesquisas Energeticas e Nucleares, provided concentrations of trace elements with accuracy levels of 10% and 9%, which are suitable for petrogenetic studies. Due to the low concentrations of the elements analyzed, the experimental routine sample preparation processes covered very careful to avoid contamination. The samples investigated can be divided into four groups: basic rocks (SiO{sub 2} <55%) with Ti / Y> 500; basic rocks with Ti / Y <500; intermediate rocks (55% 63%). Dikes of intermediate and acid composition only occur at the Sao Sebastiao Island and adjacent coastal region. The concentrations of major and minor elements, as well as the abundance patterns of rare earths and other incompatible elements of these more differentiated rocks, show significant similarities with the type of the volcanic Chapeco, suggesting similar genesis, in other worlds, including also processes of crustal contamination.

    Full Text Available The avifauna of the Araucaria forests in the higher reaches of the Serra da Mantiqueira massif is little known and poorly documented. This region is recognized as an important area of differentiation of birds in southeastern Brazil. Here, we present the first ornithological survey of the Araucaria forests and associated habitats in the mountains of extreme southern Minas Gerais state, near the southern tip of the Serra da Mantiqueira. The study area comprises the Serra do Juncal region and several adjacent sites, located in the municipalities of Gonçalves and Camanducaia. We recorded 206 bird species, of which 57 (27.7% are endemic to the Atlantic forest. Several records represent the first specimens for Minas Gerais, in the hinterlands of Serra da Mantiqueira, proving that many Atlantic species also occur in the intern most slope of this mountain range. Examples are: Dysithamnus xanthopterus, Chamaeza ruficauda, Leptasthenura setaria, Heliobletus contaminatus, Hemitriccus obsoletus, Phylloscartes difficilis, Piprites pileata, Poospiza thoracica, and Cacicus chrysopterus. The region is also a previously unknown area of sympatry of other closely related species: Scytalopus notorius and S. speluncae, Lepidocolaptes squamatus and L. falcinellus, and Basileuterus culicivorus and B. hypoleucus. Both species of Lepidocolaptes and Basileuterus hybridize in the region. We also comment on the avifauna conservation, which have been threatened by eco-tourism, building of new styles of houses, domestic animals, forest fragmentation, and plantations.A avifauna das florestas de Araucaria das partes mais elevadas da Serra da Mantiqueira é pouco conhecida e documentada.

    Cutaneous leishmaniasis (CL) in the state of Rio de Janeiro is sporadic and can be characterised as a peridomestic transmission that occurs in modified natural environments. The aim of this work was to study the fauna and ecological characteristics of sandflies in an environmentally protected area (the State Park of Serra da Tiririca) within the remnants of the Atlantic Forest in the municipalities of Niterói and Maricá and their possible relationship with leishmaniasis. Captures were performed using light traps during the night once a month for one year in both sylvatic environments and areas surrounding homes near the park. A total of 1,037 sandflies were captured, belonging to nine genera and 12 species: Evandromyia tupynambai (34.1%), Migonemyia migonei (20.6%), Brumptomyia cunhai (13.8%), Micropygomyia schreiberi (9.7%), Psathyromyia lanei (6.5%), Brumptomyia nitzulescui (5.7%), Evandromyia edwardsi (5.4%), Nyssomyia intermedia (2.8%), Evandromyia cortelezzii (0.6%), Pintomyia bianchigalatiae (0.5%), Lutzomyia longipalpis (0.2%) and Sciopemyia microps (0.1%).

    Full Text Available The lack of bioecological studies on aphids in regions with complex floristic and faunistic structure, such as the Atlantic Tropical Rain Forest, lead to the initiation of this research. The objectives were to determine species richness and diversity of aphids and to investigate the influence of altitude and environmental perturbations on aphid populations. The collections were made with yellow pan traps at 11 sites with altitudes from -10 m to 1000 m above sea level (a.s.l., in the Serra do Mar, Paraná, Brazil, from December 1993 to December 1994. Richness and diversity of aphids were greatest at 85 m a.s.l. This site was characterized by three distinct floral communities: primary vegetation, secondaiy vegetation in successional stages, and secondary vegetation subject to regular mowing. No pattern in the number or kinds of species could be established along the altitudinal gradient. These results, indicate that several factors interact, but especially floristic composition and climatic conditions, to determine aphidofauna richness and diversity in this region of the Atlantic Tropical Rain Forest.

    Full Text Available Fruit-feeding butterflies are used in ecological studies following standardized sampling protocols because they are easily collected using traps baited with food. This trait, and the fact that their populations respond rapidly to changes in habitat, make them good biological indicators. The goal of this study is to present a list of fruit-feeding butterfly species, including morphological and ecological characteristics of this group, for the Atlantic Forest of Serra do Tabuleiro State Park (Santa Catarina, to improve the knowledge about the butterflies from this region. Six field expeditions were carried out between November 2009 and August 2010. Twenty-five bait traps were used, which remained active for ten days and were checked every 48 h to replace the bait and collect individuals. Twenty species and 331 individuals were captured, which belonged to three subfamilies: Biblidinae, Charaxinae and Satyrinae. The study added eleven new species to the already existing list of the Atlantic Forest butterflies of Santa Catarina.

    Limeira city is located in the Sao Paulo State, in the second area of the State with the largest economic and demographic growth. It possesses expressive economy, with industries in several productive sections. As the Graminha and Aguas da Serra streams present its nascent ones in the urban zone of the Limeira city, they cross part of the rural zone and it unites draining in the Piracicaba River, it is possible that these basins suffer or have already suffered the impacts related to the environmental pollution caused by anthropogenic factors. Once the city have galvanization industries for the jewels, semi-jewels and bijoux production the descriptions and interpretations of the concentrations of heavy metals, in the water and in the sediments, are indicative to elucidate the influence anthropogenic and the loading of these compounds for Piracicaba River. For the metal determination Synchrotron Radiation Total Reflection X-Ray Fluorescence (SR-TXRF) was used. All measurements were performed using a white beam of synchrotron radiation for excitation and a Ge hyperpure detector. Detection limits for water samples was 0.04 -{mu}g.L{sup -1} and in sediment samples 0.03 {mu}g.g{sup -1} for Cu and Zn elements. In the water samples concentrations higher than permissive values established by CONAMA for Al, Fe, Zn, Cr, Ni, Cu and Pb were observed. For sediment samples values higher than reference value quality defined by CETESB was verified for Cr, Zn, Cu, Ni and Pb. (author)

    2012-09-01

    In the province of Chaco, Argentina, there is a very unique dispersion of metallic meteorites called ``Campo del Cielo''. One of the meteoric fragments of this dispersion, the meteorite called ``El Chaco'', consisting of 37 tons, is the second heaviest in the world. These meteorites are of great importance to the worldview of the Moqoit, aboriginal people that inhabit this region. For the local Creole population the meteorites are also relevant, that's why they have being cited in numerous documents and reports since the colonial period. During the first months of 2012, two Argentine artists and the Artistic Director of the German contemporary art exhibition called dOCUMENTA (13) tried to move ``El Chaco'' meteorite to Germany in order to exhibit it as an artistic object. Due to the fact that moving the meteorite could have a negative impact according to the Moqoit cosmology and that they were not able to participate in the decision they begun a manifestation against the movement of El Chaco. The opposition made by aboriginal communities and experts in cultural astronomy was able to stop the transfer. The whole process and its impact on the local community have promoted a deep discussion about art, science and cultural colonialism. In this paper we aim to address this debate and its consequences. This will allow us to think about contemporary forms of colonialism that are hidden in many scientific and artistic projects. Furthermore, we aim to debate about the most effective ways of protecting astronomical heritage in the Third World.

    Full Text Available In this paper we present an example of a specific metric which geometrizes explicitly a light-like four-vector potential (chiral field. The geometrization shows that such a vector has the same geometrical structure as a gravitational Kerr field. We discuss a theoretical proposition that a rotating body generates, besides a special gravitational field, a magnetic-type gauge field which might be identified with a chiral geometrized field. This chiral field represents a novel type of field because we cannot identify it with any of the known electromagnetic fields. As an application of this theory we discuss the morphology of the planets around the sun.En este trabajo se presenta un ejemplo de una métrica especifica que geometriza explícitamente un potencial cuadrivector tipo luz (campo quiral. La geometrización muestra que tal vector tiene la misma estructura geométrica que un campo gravitacional Kerr.

Este campo quiral representa un tipo novedoso de campo que no puede ser identificado con alguno de los campos electromagnéticos conocidos. Como aplicación de esta teoría se discute la morfología de los planetas alrededor del sol.

    Full Text Available This study aimed to characterize the trophic structure of the fish assemblage in streams of the Serra Japi, an ecotonal area between the Atlantic Forest and inland forests of São Paulo State, Southeastern Brazil. Fish were collected with electrofishing equipment in 15 sites covering different regions, substrate types and riparian vegetation, distributed throughout the Caguaçú River, Caxambú, Piraí and Guapeva River micro-basins, during the rainy (January/February and dry season (June of 2007. The 589 specimens analyzed from 22 species, were assigned to different trophic groups, discriminated through a matrix of similarity, based on the food index (IAi. The results show the formation of seven groups with a predominance of insectivorous and omnivorous species, followed by detritivores, piscivores, omnivore-carnivores and herbivores, which consumed mostly items of autochthonous origin, where algae and young insects were dominant. Canonical correspondence analysis (CCA, correlating the biomass of trophic groups to environmental variables, showed that omnivores, insectivores and omnivore-carnivores displayed a wide distribution, while detritivores, herbivores and piscivores were restricted to specific locations, related to different physical and chemical variables as total nitrogen, conductivity and temperature. Despite the increase in total biomass at the most urbanized sites, the results indicate that the streams maintain a diverse community, suggesting that most of them are in preserved conditions.O presente trabalho teve por objetivo caracterizar a estrutura trófica da comunidade de peixes de riachos da Serra do Japi, uma área de transição entre a Mata Atlântica e o interior paulista, no sudeste brasileiro.

    The Serra da Canastra region, located in southwestern Minas Gerais, Brazil, is recognized worldwide for its tradition of producing artisanal cheeses. However, as production is done by hand, great variability exists in the characteristics of artisanal Minas cheese. Thus, it is important to characterize the sensory profile of these products and verify the quality attributes that lead to their acceptance. Therefore, this study aimed to characterize the dynamic sensorial profile of artisanal Minas cheese produced in the Serra da Canastra region through temporal dominance of sensations and sensory acceptance tests and verify the attributes that lead to product quality. We observed that the texture and flavor profile varied among the evaluated artisanal Minas cheeses from Serra da Canastra, some cheeses being more characterized by creamy and soft or hard and firm sensations, whereas others had high dominance rates for crumbly texture. In relation to flavor, salty and bitter tastes were dominant in most cheeses, some also being characterized by a sour taste, and others by buttery and rancid attributes, which indicates a lack of product standardization. However, all samples obtained scores between 6 (liked slightly) and 7 (liked moderately), indicating good acceptability in relation to the texture and flavor of the evaluated cheeses. Moreover, it is possible to infer that creamy and soft or hard and firm are positive attributes for cheese texture, and bitter, buttery, salty, and acid taste drive cheese acceptance. This study provides important information for product standardization, quality improvement, and process origin indications, besides providing quality attributes that meet consumer desires.

    Full Text Available This study was set out with the objective of analyzing successional process in areas which are deforested and dominated by Pteridium aquilinum in the Serra da Mantiqueira mountain range, by researching the natural regeneration of shrub and tree species and evaluating both disturbance history and the edaphic conditions on the natural regeneration community. This research investigated two abandoned pasture areas in Bocaina de Minas county exposed to natural regeneration intervals ranging from six years (area named 6A to twenty years (area named 20A. The inventory occurred from sixty plots of 10 m², where all samples surveyed were between 0.15 m and 3 m high. All samples were identified and both the diameter in ground level and total height of the specimens were measured. The survey totaled 1,159 samples and 53 species. Melastomataceae was registered with the highest species richness and the highest specimen abundance. The two sampled areas showed species composition differences, with Jaccard similarity coefficient equal to 3.7%. The canonical correspondence analysis showed the correlations between natural regeneration stratum and non-labile phosphorus and clay in the 6A area. On the other hand, the 20A area showed correlations between plant regeneration and the K, P, Ca²+, Al³+ levels, with higher pH levels, and with the sum of exchangeable bases. In addition, the vegetation surveyed in area 20A was correlated with higher Pteridium population density. The results showed that the dominance of Pteridium aquilinum leads to successional process under inhibition, in which the ferns act negatively on the richness and abundance of shrub populations. It was also confirmed the Pteridium's affinity to steep areas, mainly in higher altitudes, where the soil is acid, as well as its preference to disturbed areas. Moreover, we highlight the fragilities of the mountain environments and the importance of preserving natural vegetation, as well as the bracken

    Full Text Available This study constructed a fire risk map for the Serra de São Domingos Municipal Park (SSDMP, southern Minas Gerais Sate, Brazil, which harbors Atlantic Forest remnants and endangered species. Geo-processing techniques were used for producing a preliminary risk map for altimetry (a, land slope (e, slope orientation (d, land-use/cover (u and influence of roads and buildings (i. After, the risk maps were overlaid to produce a structural fire index (SFI-based risk map for the Park. The SFI was calculated by using the formula SFI = 0,35i + 0,30u + 0,15d + 0,10a + 0,10e. The risks classes were classified as low (0.0-0.9, moderate (1.0-1.9, high (2.0-2.9, very high (3.0-3.9 and extreme (4.0-5.0. All data were processed with 2.5 m base spatial resolution by using the ArcView GIS. According to the SFI calculated, the SSMP area can be divided into the following fire risk zones: Low (0.93%, Moderate (61.77%, High (31.32%, Very High (4.79% and Extreme (1.19%. The main risk factor is due to the influence of roads and buildings and most fires start due to anthropogenic causes. The low and moderate risk classes comprehend most of the rainforest area. Clearings and grasslands fit mainly the High risk class. The most vulnerable area of SSDMP was the Northern area bordering pasture, crops and eucalypt fields. The SFI map can be a valuable tool for elaborating a fire prevention plan in a small conservation unit when few climate and fire occurrence data are available.

    Full Text Available Soil information is needed for managing the agricultural environment. The aim of this study was to apply artificial neural networks (ANNs for the prediction of soil classes using orbital remote sensing products, terrain attributes derived from a digital elevation model and local geology information as data sources. This approach to digital soil mapping was evaluated in an area with a high degree of lithologic diversity in the Serra do Mar. The neural network simulator used in this study was JavaNNS and the backpropagation learning algorithm. For soil class prediction, different combinations of the selected discriminant variables were tested: elevation, declivity, aspect, curvature, curvature plan, curvature profile, topographic index, solar radiation, LS topographic factor, local geology information, and clay mineral indices, iron oxides and the normalized difference vegetation index (NDVI derived from an image of a Landsat-7 Enhanced Thematic Mapper Plus (ETM+ sensor. With the tested sets, best results were obtained when all discriminant variables were associated with geological information (overall accuracy 93.2 - 95.6 %, Kappa index 0.924 - 0.951, for set 13. Excluding the variable profile curvature (set 12, overall accuracy ranged from 93.9 to 95.4 % and the Kappa index from 0.932 to 0.948. The maps based on the neural network classifier were consistent and similar to conventional soil maps drawn for the study area, although with more spatial details. The results show the potential of ANNs for soil class prediction in mountainous areas with lithological diversity.

    Full Text Available The Cerrado is the second largest biome in Brazil after the Amazon and is the savanna with the highest biodiversity in the world. Serra Tombador Natural Reserve (STNR is the largest private reserve located in Goiás State, and the fourth largest in the Cerrado biome. The present study aimed to map the burnt areas and to describe the spatial patterns of fire recurrence and its interactions with the classes of land-cover that occurred in STNR and its surroundings in the period between 2001 and 2010. Several Landsat TM images acquired around the months of July, August and September, coinciding with the region’s dry season when fire events intensify, were employed to monitor burnt areas. Fire scars were mapped using the supervised Mahalanobis-distance classifier and further refined using expert visual interpretation. Burnt area patterns were described by spatial landscape metrics. The effects of fire on landscape structure were obtained by comparing results among different land-cover classes, and results summarized in terms of fire history and frequencies. During the years covered by the study, 69% of the areas analyzed had fire events. The year with the largest burnt area was 2004, followed by 2001, 2007 and 2010. Thus, the largest fire events occurred in a 3-year cycle, which is compatible with other areas of the Brazilian savanna. The regions with higher annual probabilities of fire recurrence occur in the buffer zone around the park. The year 2004 also had the highest number of burnt area patches (831. In contrast, the burnt area in 2007 showed the most extensive fires with low number of patches (82. The physiognomies that suffered most fires were the native savanna formations. The study also identified areas where fires are frequently recurrent, highlighting priority areas requiring special attention. Thus, the methodology adopted in this study assists in monitoring and recovery of areas affected by fire over time.

    In the northern area of Campos Basin salt gliding/spreading processes promoted the break-up and transport of Cretaceous and Tertiary rocks overlying the evaporites. This process is known as raft tectonics, and it represents the most extreme form of thin-skinned extension above the salt decollement surface. Three distinct geotectonic domains were recognized that formed in response to the raft tectonics. The first one, confined to the shallower shelf portion of the basin, is characterized by minor extension (pre-raft domain), probably because of small salt thickness and low gradient. In the second domain (or disorganized rafts domain), located in distal platformal and slope areas, seismic sections show the occurrence of blocks or rafts with angular shapes, sometimes imbricated and frequently discontinuous. In the third domain, or domain of organized rafts, located in bacinal region, seismic sections show a more continuous raft pattern, often folded because of salt compression in the distal portions of the basin. The main purposes of this work is to characterize these three tectonic domains distinguished by raft tectonics, as well as their importance in hydrocarbon accumulations in calcarenites. (author)

    There are numerous applications given to clays including oil and water adsorbent, ceramic, whitening of beverages, porcelain, waste treatment, organic carrier molecules in cosmetics and pharmaceuticals, support for catalysts. In the pharmaceutical industry, the clays are used as excipients, diluents, desiccants, emulsifiers, to mask undesirable flavors, isotonic agent such as charger and delivery of active substances. These characteristics have contributed to the expansion of the search for applications of clay minerals in the cosmetic industry. The aim of this study was to determine the elemental composition of clays from Campos Gerais, Minas Gerais, with a view to their applicability in the production of cosmetics. The elements As, Ba, Br, Ce, Cl, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Nd, Rb, Sb, Sc, Sm, Ta, Tb, Th,U, Yb and Zn were determined by neutron activation analysis and radionuclide activity concentration of {sup 226}Ra, {sup 228} Ra, {sup 210}Pb and {sup 40}K were determined by gamma spectrometry. It was verified that the activity concentration of radionuclides was in the same concentration as the global average, indicating that these samples do not present a risk of increased radiation exposure. The concentration of most elements determined is less than or equal to the overall mean concentrations, indicated by the values of Continental Upper Crust. (author)

  9. Energy and Mass Balance At Gran Campo Nevado, Patagonia, Chile

    Science.gov (United States)

    Schneider, C.; Kilian, R.; Casassa, G.

    The Gran Campo Nevado (GCN) Ice Cap on Peninsula Muñoz Gamero, Chile, is lo- cated in the southernmost part of the Patagonian Andes at 53S. It comprises an ice cap and numerous outlet glaciers which mostly end in proglacial lakes at sea level. The total ice covered area sums up to approximately 250 km2. GCN forms the only major ice body between the Southern Patagonian Icefield and the Street of Magallan. Its almost unique location in the zone of the all-year westerlies makes it a region of key interest in terms of glacier and climate change studies of the westwind zone of the Southern Hemisphere. Mean annual temperature of approximately +5C at sea level and high precipitation of about 8.000 mm per year lead to an extreme turn-over of ice mass from the accumulation area of the GCN Ice Cap to the ablation areas of the outlet glaciers. Since October 1999 an automated weather station (AWS) is run continuously in the area at Bahia Bahamondes for monitoring climate parameters. From February to April 2000 an additional AWS was operated on Glaciar Lengua a small outlet glacier of GCN to the north-west. Ablation has been measured at stakes during the same pe- riod. The aim of this study, was to obtain point energy and mass balance on Glaciar Lengua. The work was conducted as part of the international and interdisciplinary working group SGran Campo NevadoT and supported by the German Research Foun- & cedil;dation (DFG). Energy balance was calculated using the bulk approach formulas and calibrated to the measured ablation. It turns out, that sensible heat transfer is the major contribution to the energy balance. Since high cloud cover rates prevail, air tempera- ture is the key factor for the energy balance of the glacier. Despite high rain fall rates, energy input from rain fall is of only minor importance to the overall energy balance. From the energy balance computed, it was possible to derive summer-time degree-day factors for Glaciar Lengua. With data from the nearby

    2005-03-01

    New Re-Os molybdenite ages provide constraints on the timing of Late Archean Cu-Au-Mo mineralization in the northern Carajás Mineral Province. Molybdenite from the Gameleira iron oxide Cu-Au-Mo deposit yielded an age of 2,614±14 Ma. This age overlaps within its analytical error with Re-Os ages of molybdenite from the Serra Verde Cu-Au-Mo vein deposit (2,609±13 Ma) and from the nearby small Garimpo Fernando gold mining operation (2,592±13 and 2,602±13 Ma), which is probably related to the latter. The geochronological data imply that the hydrothermal Cu-Au-Mo mineralization in these three deposits was epigenetic and coincides with a regional tectonic regime changing from dextral transtension and clastic sedimentation at 2.7 2.6 Ga to sinistral transpression and inversion at 2.6 Ga. Previously reported stable isotope and microthermometric data are compatible with a magmatic affiliation of the Cu-Au-Mo ores at Gameleira and Serra Verde. A genetic relationship of mineralization may therefore exist with 2.56 2.76 Ga Archean alkaline granitoids or with 2.6 2.7 calc-alkaline to tholeiitic volcanic-arc type magmatism.

    Analogue experiments were carried out to get insights into the processes governing positive inversion during the foreland propagating thrust tectonics in the southern Serra do Espinhaço, a Brasiliano/Panafrican foldthrust belt in southeast Brazil. In particular, model listric half-grabens were inverted by applying contractional displacement to the footwall blocks. We investigated two different inversion conditions in listric half-grabens: (i) extensional and contractional detachments at the same level and (ii) at different positions. The models revealed that the development of a forward-breaking thrust system occurs in the basin synrift deposits, by contractional translation of the extensional footwall block when the extensional and contractional master faults do not coincide. Our experiments show the tectonic imbrication between basement and synrift sequences which characterizes the southern Serra do Espinhaço, and support the location in the eastern mountain range domain of the Espinhaço rift master fault system, which is not exposed at the surface.

A figure of wounded deer facilitates some parallel referred to its construction and the perspective used in the extremities, or to the unusual morphology of the weapon. This study allows to establish a narrow linking with the premagdalenian art of other caves nearby, and facilitates an up-to-date discussion on the temporary modification in the perspective in animal representations during the Upper Palaeolithic.

    The Albacore and Marlim giant fields are located in the province of Campos basin, about 110 km (68 mi) offshore Cape Sao Tome, in water depths ranging from 200 m (656 ft) to 2,000 m (6562 ft). The Albacora field was discovered in September 1984 by the wildcat 1-RJS-297, drilled in 293 m (961 ft) of water. Subsequently, the wildcats 1-RJS-305 and 1-RJS-342 extended the field limits to deeper waters. The Albacora field is approximately 235 km{sup 2} (90 mi{sup 2}) in area, with an estimated volume of 4.5 billion bbl of oil in place. The Marlim field was discovered in February 1985 by the wildcat 1-RJS-219A, in a water depth of 853 m (2,800 ft). The Marlim field area is about 152 km{sup 2} (58 mi{sup 2}), and the latest estimate of oil in place is about 8.2 billion bbl. The Marlim complex encompasses Marlim field itself and the surrounding proved and potential areas known as East-of-, West-of-, and South-of-Marlim, respectively. The current estimated volume of oil in place in the Marlim complex is close to 13.9 billion bbl, with a total surface of about 350 km{sup 2} (135 mi{sup 2}). Oil production in the Albacora field comes from Lower Cretaceous (Albian) and Tertiary (Eocene, Oligocene, and Miocene) turbidite reservoirs. Oligocene turbidite sandstones are the potential reservoirs in the Marlim field. These deposits are genetically associated with sea level variations and are mainly composed of massive sandstones and, subordinately, of contourites. Both fields are structurally and stratigraphically controlled accumulations. Hydrocarbons are trapped in anticlines and/or faulted blocks associated with salt tectonics. Stratigraphic contributions result from sandstone bodies pinching out against shales and marls. The development of these fields has been supported by three-dimensional seismic data. The Albacora field is being gradually put on stream from shallower to deeper waters.

    Due to the irregular occurrence of rainfall in Brazilian Savannas, associated with a vast range of models that aim to evaluate it, this study was carried out to estimate the monthly amount of rainfall, at different probability levels, in Tangará da Serra, Mato Grosso State, Brazil, by using the Gamma function. Pluviometric data from 1970 to 2007 (38 years, provided by the Agência Nacional de Águas (ANA, collected in a pluviometric station located at 14°37’55”S, 57°28’05”W, and 488 m of altitude, were used. The adjustment analysis between estimated and observed data was carried out in accordance with the Kolmogorov-Smirnov adherence test, at 5% of significance, resulting in no significant differences for monthly periods, including those with several values equal or close to zero, allowing the Gamma distribution use. The highest expected monthly precipitation levels took place from November to March (rainy season, while from June to August were noticed the lowest ones (dry period. The other months can be considered as intermediaries between the dry and rainy seasons.

    The Serra de Tramuntana, which forms the backbone of the north-west of Mallorca (Spain), was declared in 2011 World Heritage Site by UNESCO under the cultural landscape category. The particular landscape of this range is the fruit of the exchange of knowledge between cultures, with small-scale works performed collectively for a productive aim, conditioned by the limitations imposed by the physical medium. The steep topography of the chain, highly related to its geological complexity, and the Mediterranean climate, influence intense slope dynamics with the consequent multiple types of slope failures: rock slides, earth landslides and rockfalls, which cause significant damage and specifically to the road network (Mateos, 2013a). The human landscape marked by agricultural terraces (dry stone constructions) has significantly contributed to the slope stability in the range for centuries. In the present work, a landslide inventory map with 918 events has been updated and the landslides state of activity was analyzed exploiting 14 ALOS PALSAR satellite SAR (Synthetic Aperture Radar) images acquired during the period 2007-2010. Landslide activity maps were elaborated through the use of PSI (Persistent Scatterers Interferometry) technique (Bianchini et al., 2013). Besides assessing the PS visibility of the study area according to the relief, land use and satellite acquisition parameters, these maps evaluate, for every monitored landslide, the average velocities along the satellite Line Of Sight (VLOS) and along the maximum local steepest slope (VSLOPE), providing an estimate of their state of activity and their potential to cause damages. Additionally, a ground motion activity map is also generated, based on active PS clusters not included within any mapped landslide phenomenon. A confidence degree evaluation is carried out to attest the reliability of measured displacements to represent landslide dynamics. Results show that 42 landslides were identified as active (VSLOPE

    The Serra dos Órgãos batholith in the State of Rio de Janeiro (Brazil) is a NE-SW-trending elongated body that occupies ca. 5000 km2 in plan view. It is a foliated intrusion, especially at its borders and is crosscut by syn-magmatic shear zones, with foliations that are moderately-to steeply-dipping to the northwest and moderately-to shallow-dipping in the center and to the southeast, in a configuration of a large laccolith. It was emplaced between 560 and 570 Ma, during an extensional episode that was part of a series of events that comprise the Brasiliano Orogeny in SE Brazil, and which includes deformation, metamorphism and granite intrusion during the interval between 630 and 480 Ma. The two main rock types in the batholith are biotite-hornblende monzogranite, and biotite leucogranite, with subordinate tonalite, granodiorite, diorite, quartz diorite (enclaves), aplite and pegmatite. Harker-type diagrams help show two rock groups with similar trends of evolution: a dioritic and a granitic. The first one is tholeiitic, whereas the second is calc-alkaline, with medium-to high-K calc-alkaline affinity and metaluminous to slightly peraluminous character. In both groups strong decrease in Al2O3, MgO, FeOT and CaO relative to silica contents are observed, which is compatible with trends of fractional crystallization involving clinopyroxene and/or hornblende, plagioclase, opaque minerals, apatite, microcline and biotite. The Sr and Nd isotopic data suggest recycling of a Paleoproterozoic crust as an important petrological process to generate the batholith rocks. Geothermometry (amphibole composition) and geobarometry (saturation in zircon and apatite) indicate that most of the batholith solidified at mid to lower crustal levels at about 750 °C and between 5 and 5.5 kbar. We consider that Serra dos Órgãos crustal protoliths underwent melting caused by the interaction with hotter mafic magma at the base of the crust. These two magmas, with distinct initial

  4. Deposition of trace substances via cloud droplets in the Atlantic Rain Forest of the Serra Do Mar, São Paulo State, SE Brazil

    Vautz, W.; Pahl, S.; Pilger, H.; Schilling, M.; Klockow, D.

    The Atlantic Rain Forest of the Serra do Mar close to Cubatão, São Paulo State, SE Brazil, is severely affected by the emissions of a big industrial complex. Measurements of trace substance concentrations in air as well as in rain were carried out over a period of 6 years to investigate the interrelation of pollution and vegetation damage. Due to the local atmospheric circulation, orographic clouds occur very frequently at the top of the Serra do Mar, where vegetation damage also is very high. Therefore, additional information was required about trace substance deposition via cloud water. During three field experiments, various samples of cloud water and of the interstitial aerosol were taken by help of a sampling device especially modified for this purpose, and were analysed for the major anions and cations (hydrogen ions, ammonium, chloride, sodium, nitrate and sulphate). The trace substance concentrations found in cloud water were in the same range as for polluted sites in Europe. Over all samples, about 90-100% of the trace substances—both gaseous and particulate matter—found in the atmosphere before a cloud event were found in the cloud water. A resistance model using meteorological input data (wind speed, atmospheric liquid water content) was adapted to the characteristics of the Atlantic Rain Forest to estimate the cloud water deposition to vegetation. The results from cloud water analyses and from modelled cloud water deposition were combined to investigate the ion deposition to the vegetation. A rough estimate of the annual deposition showed, that the deposition via rain is in the order of one magnitude (factor 6-40) higher than that via cloud. The high amount of water deposition via precipitation overcompensates the higher trace substance concentrations in cloud water. Furthermore the trace substance deposition to vegetation via cloud water in the Atlantic Rain Forest is in the order of one magnitude lower than for typical German spruce forests due

    Full Text Available Data on species composition, richness, and density are presented for the leaf litter frog assemblage of an area of Atlantic Rainforest at the Serra dos Órgãos mountain range, in the state of Rio de Janeiro, southeastern Brazil. Three sampling methods were used: plot sampling, visual encounter surveys, and pitfall traps. The local assemblage of leaf litter frogs was composed of 16 species, with the direct-developing species, Euparkerella brasiliensis (Parker, 1926, being the most abundant. The estimated density of the local leaf litter frog assemblage based on plot sampling was 17.1 ind/100 m² and the estimated overall leaf litter frog mass was 684.2 g/ha. The estimated density of leaf litter frogs at the present study is the highest currently reported for Atlantic Rainforest areas, which reinforces the idea of higher densities of leaf litter frogs in the Neotropical Region compared to the Old World tropics.

The first succession was generated by a low rate of eruption in a closed flow system allowed the flow toreach distances > 100 km of the source.T he ´a´ā lava flow types were generated by higher rates of eruption andt ransported in openchannels where rapid cooling prevented long distances from the source to be reached. The two types of basalts are low-TiO2 tholeiiticand the morphology of flows is not related to variations in SiO2 and MgO contents. Above these rock types outcrop acidic volcanicrocks geochemically of Caxias Group (Palmas Subgroup. Dimension stones extraction exposed the inner portions of the acidicfeeder dikes with vertical magmatic foliations. The lava domes have exogenous characteristics and horizontal foliations. We proposea model for the generation of domes involving the diapirically rise of acids magmas that become vesicular and more viscous, thatstop near the surface. New magmatic pulses extracted “pieces” of the vesicular fraction generating autobreccias in the conduit andvertical structures that extend laterally toward the surface organizing the lava domes with vitrophyres in the base and in the top, witha thin massive phaneritic core. Magmatic textures of the domes are typical of effusive units and the identification of the feeder dykesin the area allows the understanding of the emplacement process of acidic flows in the Serra Geral Formation.

  3. Actual stage of organic geochemical knowledge from Campos and Espirito Santo basins, Brazil

    International Nuclear Information System (INIS)

    Campos and Espirito Santo basins display several similar geochemical aspects. The microbial and other degradation processes caused changes in the composition of the oils in the reservoir rocks. The oils are biodegraded in different degrees, with the reservoir temperature developing an important role in the control of the biodegradation process. The migration pathway model is similar for Campos and Espirito Santo basins, involving the upward secondary migration through a window in the evaporitic seals. The oils passed to the marine sequence where migration and accumulation were controlled by faults, regional unconformities and by reservoirs. The geochemical correlation of oils are realized by gaseous and liquid chromatography analysis, carbon isotopes and biolabelled compounds. (author)

  6. El arte rupestre de la fachada mediterránea: entre la tradición epipaleolítica y la expansión neolítica

    Full Text Available RESUMEN: El Arte Levantino se caracteriza por las representaciones naturalistas de personas y animales, por escenas de caza que muestran hombres armados con arcos o en actitud de disparo y animales heridos. Se ha considerado propio del modo de vida epipaleolítico cazador-recolector. Además, en la fachada mediterránea se reconocen otros dos tipos de arte rupestre. El Arte Macroesquemático, limitado a una de sus zonas, expresión de una nueva religiosidad neolítica de origen mediterráneo. Y el Arte Esquemático, en parte identificado con el anterior y en parte coincidente con los nuevos símbolos religiosos del Calcolítico. En las últimas décadas, el modelo de una dualidad cultural, formada por los grupos neolíticos y por el substrato epipaleolítico, atribuía a los primeros el Arte Macroesquemático y el primer Esquemático, mientras el Levantino pertenecía a los grupos epipaleolíticos que se neolitizan. El estudio de las superposiciones, de los paralelos muebles y del propio proceso de neolitización conducen ahora a considerar que el Arte Levantino corresponde a las primeras sociedades neolíticas.ABSTRACT: The Levantine Arr is characterised by naturalisric depictions of people and animals, by hunting scenes showing men with bows and arrows and hurt animals. It has been considered to show the hunting and gathering Epipalaeolithic way of life. In addition, two more different art traditions are known in the Mediterranean façade of the Iberian Peninsula. The Macroschematic Art, with a very restricted distribution, shows the new Neolithic religious mentality of Mediterranean origin. On the other hand, rhe Schematic Art has mixed features of the Neolithic and Copper Age imagery. In the last decades, within the model of cultural duality, the Neolithic groups were considered the authors of the Macroschematic and the first Schematic Art, while the Levantine Art was made by the Epipalaeolithic groups adopting the Neolithic way of life.

    Full Text Available The objective of the present study was to characterize the richness (number of species of large and medium-sized mammals, and the antropic threats in the Parque Nacional da Serra do Divisor (PNSD. In 31 days data were collected through direct observations or evidences (bones, hairs, vocalizations and tracks along pre-existing trails distributed in different types of vegetation. Wild mammals captured by local people were also considered. They were found 44 species of terrestrial mammals (with the exception of small mammals and bats and two species of cetaceans, representing 73% of the total predicted, according to the literature and information of local dwellers were registered in PNSD. They exist in the area two species classified by IUCN (1996 as "Endangered" [Cacajao calvus rubicundus (I. Geoffroy, 1806 and Priodontes maximus (Kerr, 1792] and five as "Vulnerable" [Ateles chamek (Humboldt, 1812, Callimico goeldii (Thomas, 1904, Lagothrix lagotricha poeppigii (Humboldt, 1812, Myrmecophaga tridactyla Linnaeus, 1758 and Inia geoffrensis (Blainville, 1817]. Given that subsistence and commercial hunting are common in the PNSD, mammals more affected by hunting [Ateles chamek (Humboldt, 1812, Lagothrix lagotricha (Humboldt, 1812, Tayassu pecari (Link, 1795] were observed only in the more remote areas such as Serra do Divisor, Rio Moa.

    Full Text Available A doença de Alzheimer é uma enfermidade neurodegenerativa, progressiva e irreversível, de aparecimento insidioso, e com a evolução da doença seu portador perde a autonomia e precisa de um cuidador que lhe dedique total atenção. Diante deste contexto, este trabalho objetivou descrever e compreender como ocorre a reconfiguração de campo do familiar cuidador responsável pelo portador de Alzheimer. Para tanto, realizou-se uma pesquisa qualitativa, pautada na perspectiva fenomenológica e na teoria de campo, fundamento teórico da abordagem Gestáltica, e utilizou-se o método de Amedeo Giorgi. O estudo desenvolveu-se com três cuidadoras familiares de pacientes portadores de Alzheimer diagnosticados havia mais de seis meses. Encontraram-se quatro categorias que descrevem a reconfiguração do campo das cuidadoras: Assumindo a responsabilidade em cuidar; Mudanças na família; Rede de apoio social; e Estratégias de enfrentamento. Concluiu-se que o processo de reconfiguração do campo do familiar cuidador é longo e passa por diversas reestruturações dinâmicas e estruturais.

    Full Text Available This paper approaches the recent strategies of building construction in the metropolitan area of Vitoria (RMGV. It focuses on the transformations of urban space in the municipality of Serra-ES, whose urban dynamics was related historically to the peripheral expansion of the metropolis since 1970. Thus, the forms of housing construction were articulated, above all, with the reproduction of the lower income population, such as lots and housing for the working class. In recent years, the city is a privileged stage for real estate investment materialized in new spatial forms, such as horizontal and vertical condominiums. In the real estate dynamics of the metropolis, Serra emerges as another front in the performance of real estate capital, which is based on promoting a new product in the State of Espírito Santo market, gated communities and image associated with security, access to nature etc. The activity of capitalist building production in the city is marked by new relations promoted by large corporations, publicly traded on the stock exchange, which establish partnerships with local companies.

    Full Text Available The pollinators and breeding system of two species of Vellozia (Velloziaceae from high-altitude quartzitic grasslands in SE Brazil were studied. Vellozia leptopetala is shrubby and grows solely on rocky outcrops, V. epidendroides is herbaceous and grows on stony soils. Both bear solitary, hermaphrodite flowers, and have massive, short-lasting annual blooms. We evaluated the level of self-compatibility and need for pollinators of 50 plants of each species and 20-60 flowers per treatment: hand self- and cross-pollination, spontaneous pollination, agamospermy and control. The behavior of floral visitors on flowers and within plants was recorded. Both species are mostly self-incompatible, but produce a small number of seeds by self-fertilization. The pollen-ovule ratio suggests facultative xenogamy. They were visited primarily by bees, of which the most important pollinators were two leaf-cutting bees (Megachile spp.. Vellozia leptopetala was also pollinated by a territorial hummingbird. Low natural seed production compared to cross-pollination seed numbers suggests that pollen limitation is the main cause of low seed set. This was attributed to the combined effect of five mechanisms: selfing prior to anthesis, enhanced geitonogamy as a result of large floral displays, low number of visits per flower for the same reason, pollen theft by many insect species, and, in V. leptopetala, delivery of mixed pollen loads on the stigma as a consequence of hummingbird promiscuity.Foram pesquisados os polinizadores e o sistema reprodutivo de duas espécies de Vellozia (Velloziaceae de campos rupestres quartzíticos do sudeste do Brasil. Vellozia leptopetala é arborescente e cresce exclusivamente sobre afloramentos rochosos, V. epidendroides é de porte herbáceo e espalha-se sobre solo pedregoso.

L. fischeri was the dominant species at the canopy, where it fed chiefly on the chicken and from 4 to 5 a.m., although at ground level it fed mostly from 8 to 12 p.m. and preferred man.

    Full Text Available Graxains-do-campo habitam o centro-leste da América do Sul, desde o sudeste do Brasil e leste da Bolívia. A displasia renal compreende um espectro de anomalias e é frequentemente relatada em cães de diversas raças, sendo a maioria dos relatos achados de necropsia. A maior parte das doenças renais congênitas nos cães apresenta caráter progressivo, portanto o tratamento é limitado e direcionado a fim de retardar a progressão da doença renal estabelecida. No presente relato é descrita a realização de nefrectomia laparoscópica em graxaim-do-campo (Pseudalopex gymnocercus com displasia renal. Suspeitou-se de doença no rim direito por meio de ultrassonografia e urografia excretora. Para o procedimento cirúrgico foram utilizados três portais (10, 10, 5mm, endoscópio rígido de 10mm/0(0 e clipes para hemostasia dos vasos renais. A técnica cirúrgica utilizada neste canídeo selvagem foi semelhante à usada em cão doméstico, devido à escassez de relatos em cirurgias em graxaim e a inexistência de descrições de nefrectomia videolaparoscópica em graxaim-do-campo. O animal foi acompanhado por um período de 30 dias pós-cirurgia sem a ocorrência de complicações. O presente relato demonstra que a técnica proposta foi adequada para a realização de nefrectomia videolaparoscópica em Graxaim-do-campo.

El objetivo de esta investigación es demostrar la pertinencia del supuesto teórico darwinista de selección natural en la discriminación de belleza escénica de la figura del bailarín en el sistema piramidal de selección, formación y desempeño profesional del campo cubano del ballet. El campo del ballet se registra fácticamente en instituciones culturales pobladas por individuos que persiguen cotidianamente crear bailarines profesionales aptos -primera condición es ser revolucionario- que representen internacionalmente a la Revolución Cubana. El campo se estructura en un sistema piramidal de selección, formación y desempeño de bailarines profesionales que rige sus prácticas principales de exclusión/inclusión -puntos de corte- por el principio darwinista de selección natural. Los exámenes de capacidades físicas de ingreso y pase de nivel a la enseñanza de nivel medio y la aceptación a la compañía profesional Ballet Nacional de Cuba conforman los puntos de corte del sistema piramidal. Estos contienen prácticas sociales que valoran -empírica, pero sistemáticamente- las características morfo-funcionales de los participantes interesados respecto al deber ser del canon artístico de figura, para seleccionar siempre a los más bellos, los más aptos, bailarines de ballet.

    Biodiversity studies allow ecosystem assessment and monitoring of environmental changes and impacts. Parasite diversity could reflect the host/ parasite coevolutionary process and the environment changes that permit the loss, gain or maintenance of species. This survey used species/morphotypes of helminths eggs found in feces from seven wild mammal species (the groups Dasypodidae and Large Cats, and Tamandua tetradactyla, Cebus apella, Alouatta caraya, Cerdocyon thous, Pecari tajacu) and from two domestic species (Canis familiaris and Sus scrofa), which occur within the Serra da Capivara National Park (PNSC) and surrounding areas in order to analise the diversity of mammal intestinal helminths. This work used the helminthological fauna findings of wild and domestic mammals, to consider a possible helminth flux between these two host groups using Unweighted Pair Group Method with Arithmetic Mean (UPGMA) of the hosts based on helminthological fauna composition. The results indicate that the region of the PNSC still maintains environmental conditions that still keep wild mammal helminthological fauna composition different from the one found for domestic mammals.

    Full Text Available Three northern areas of Parque Estadual da Serra do Brigadeiro (PESB were sampled for terrestrial medium- and large-sized mammals, using camera traps, for twelve months. Nine wild species and one domestic species were registered, through 49 records. The community’s composition was based on an exponential series with dominance of few species. In contrast, there was a relatively high proportion of species that might be “rare” in the community observed, with dominance of puma (Puma concolor over the other ones. The results show that the area named Vale Perdido is the most important one for the conservation of mammals, because the estimated species richness is higher there (13.99 ± 2.23 when compared to that of the other two areas, which had a richness of 6.00 ± 1.41 and 6.00 ± 1.00, respectively. It’s possible that the structural and spatial characteristics of Vale Perdido favored the use of this area by the species. The structure of the community of medium-and large-sized terrestrial mammals of PESB is unstructured or in a structuring phase. Possibly, this model was caused by negative historical effects of the occupation and extraction that the region underwent in the 1960s.

    Grasslands are the most threatened physiognomies of the Cerrado biome (Brazilian savanna), a biodiversity hotspot with conservation as a priority. The Serra da Canastra National Park protects the most important remnants of the Cerrado's southern grasslands, which are under strong anthropogenic pressure. The present study describes the structure of bird assemblages that directly use food resources in burned areas, comparing areas affected by natural fire to the areas where controlled fires were set (a management strategy to combat arson). The tested null hypothesis was that different bird assemblages are structured in a similar manner, regardless of the post-fire period or assessed area. Between December/2012 and January/2015, 92 species were recorded foraging in the study areas. The results indicate that both types of burnings triggered profound and immediate changes in bird assemblages, increasing the number of species and individuals. Natural fires exhibited a more significant influence on the structure (diversity and dominance) than prescribed burnings. Nevertheless, all the differences were no longer noticeable after a relatively short time interval of 2-3 months after prescribed burnings and 3-4 after natural fires. The findings may help the understanding of prescribed burnings as a management strategy for bird conservation in grasslands. PMID:27192195

    Full Text Available The structure of western Serra do Curral, Quadrilátero Ferrífero, represents the partial exposure of a syncline that verges to NNW – Piedade Syncline. This regional structure has parasitic folds denominated as B1A which are refolded by folds B1B that also have vergence to NNW. Both of them have ENE-WSW direction, are non-cylindrical folds and configure an interference pattern that is similar to Type 3 from Ramsay. This refolding occur during progressive deformation. The occurrence of high-grade magnetitic-martitic accumulation (> 64% Fe of medium size (~ 100 Mt is controlled by the combination of these folds and high angle thrust fault, both with the same direction. Above these structures, there is a development of folds with NNW- SSE direction and WSW vergence (B2 folds. These folds are restricted to the B1 limbs and they configure an interference pattern named “abbuting fold”. The age obtained by U/Pb SHRIMP on monazite grains is 2034±11 Ma. The monazite grains occur on textural balance with the iron oxide from high-grade accumulations. This age corresponds to the formation timing of the high-grade bodies and suggests that the mineralization process is contemporary to the regional metamorphic peak of Quadrilátero Ferrífero.

Systematized biweekly human bait collections were made three times a day, for periods of 2 or 3 h each, in sylvatic and rural areas for 24 consecutive months (January 1991 to December 1992. A total of 24,943 adult mosquitoes belonging to 57 species were collected during 622 collective periods. Aedes scapularis, Coquillettidia chrysonotum, Cq. venezuelensis, Wyeomyia dyari, Wy. longirostris, Wy. theobaldi and Wy. palmata were more frequently collected at swampy and at flooded areas. Anopheles mediopunctatus, Culex nigripalpus, Ae. serratus, Ae. fulvus, Psorophora ferox, Ps. albipes and the Sabethini in general, were captured almost exclusively in forested areas. An. cruzii, An. oswaldoi and An. fluminensis were captured more frequently in a residence area. However, Cx. quinquefasciatus was the only one truly eusynanthropic. An. cruzii and Ae. scapularis were captured feeding on blood inside and around the residence, indicating that both species, malaria and arbovirus vectors respectively, may be involved in the transmission of these such diseases in rural areas.

    Full Text Available ABSTRACT This work reports the dating of a fossil human tooth and shell found at the archaeological site Toca do Enoque located in Serra das Confusões National Park (Piauí, Brazil. Many prehistoric paintings have been found at this site. An archaeological excavation unearthed three sepulchers with human skeletons and some shells. Two Brazilian laboratories, in Ribeirão Preto (USP and Recife (UFPE, independently performed Electron Spin Resonance (ESR measurements to date the tooth and the shell and obtain the equivalent dose received by each sample. The laboratories determined similar ages for the tooth and the shell (~4.8 kyBP. The results agreed with C-14 dating of the shell and other samples (charcoal collected in the same sepulcher. Therefore, this work provides a valid inter-comparison of results by two independent ESR-dating laboratories and between two dating methods; i.e., C-14 and ESR, showing the validity of ESR dating for this range of ages.

Therefore, sixteen questions were applied before and after the course, so it was established that 100% of the teachers knew the names of the phases of the moon, 97.0% understood that the Solar System is composed by eight planets, 78.1% explained as occured "Lunar Eclipse", "Solar Eclipse" and "Solstice", 72.7% knew to explain the occurrence of the seasons of the year; 64.5% explained the occurrence of the equinox correctly, 89.7% were able to define properly "comet"; 63.6% defined "Asteroid", 54.5% defined "meteor"; 58.1% defined "galaxy", and 42.4% defined "planet".

    Metasiliciclastic rocks predominate in the lower units of the Palaeo-Mesoproterozoic Espinhaço Supergroup, in the southern Serra do Espinhaço, Minas Gerais, Brazil. The lower units also comprise rocks with locally preserved igneous fabrics, but which have very unusual chemistries. These rocks, collectively known as hematitic phyllite, are characterised by abundant fine-grained muscovite, i.e. sericite, and variable amounts of titaniferous hematite, rutile and tourmaline. Currently, the hematitic phyllite has been interpreted as a metamorphosed palaeosol after basaltic rocks and, as such, has been used as a palaeoclimatic indicator. However, the lateritic nature of the hematitic phyllite cannot unambiguously be determined because of the K metasomatism, hematitisation and tourmalinisation recorded in the hematitic phyllite and in the arenaceous country rocks. Here we report the B-isotopic and chemical compositions of tourmaline from the hematitic phyllite. Our δ11B data are in the range between - 15‰ and 4‰. The tourmaline compositions fall along the povondraite-"oxy-dravite" join, which defines a meta-evaporitic tourmaline trend. A meta-evaporitic B source is constrained by the B-isotopic data as non-marine. Our model for the hematitic phyllite suggests that B- and K-rich brines were derived from the metamorphic dewatering of non-marine evaporites. Such brines extensively altered volcanic rocks of basaltic and rhyolitic compositions, leading to tourmaline-bearing, hematite-sericite assemblages of the hematitic phyllite.

    Full Text Available In February 2001, an accidental spill dumped 52,000 litres of diesel oil in Serra do Mar, Paraná state, Brazil, contaminating streams. This study aimed to evaluate if fish communities currently inhabiting environments exposed to the oil spill still showing evidence of spill-related impacts. Ichthyofauna communities were monitored in five rivers located in the region of the spill. Two sites exposed to oil (Meio and Sagrado rivers were considered treatment sites, and three unexposed sites with environmental characteristics similar to the treatment sites (Pinto, Passa Sete and Marumbi rivers were considered control sites. Analysis of water quality parameters indicated that sites within rivers were more similar than sites among rivers. The diversity and species composition of fish communities differed between the treatment and control groups and among the rivers. The distribution and species composition of ichthyofaunal communities likely reflect the environmental characteristics of each river and not related to the environmental contamination resulting from the oil spill.

    In this study, four mixtures of LDPE post consumer with heavy gas from the Campos Basin, in different proportions, were subjected to pyrolysis in an inert atmosphere at 550 deg C. The pyrolytic liquids were characterized by gas chromatography coupled to mass spectrometry (GC/MS). Pyrolysis of pure diesel supplied large amounts of waste oil and only 4% in the range of diesel. On the other hand, the pyrolysis of LDPE mixture of diesel (at the ratio 1/0,5 m/m) provided 20% of light hydrocarbons with high production of pyrolytic oil (96%). The formation of high levels of paraffins and olefins in the range of diesel oil during the co-pyrolysis suggests a promising technology for recycling of plastic waste. (author)

    This article focus on an innovative project launched by PETROBRAS with the main purpose of minimizing the impacts of drilling activities in Campos Basin, over the fishery industry in the northeast region of Rio de Janeiro. This project is seen as a relevant part of PETROBRAS' corporate social responsibility actions. In this sense, it is supposed to consider the interests of all parts directly and indirectly related and affected by the companies' intervention. The major conclusion is that the project could be an important first step to restructure the fishery sector an to harmonize the 'sea users'. A potential improvement could be the promotion of a more effective participation of fishermen in the project and the inclusion of the social and environmental dimensions. (author)

    An integrated paleoecological, biostratigraphic and cyclostratigraphic study was carried out on sedimentary rhythm sequences in the Oligocene-Miocene of the Campos Basin, Brazil. The bio stratigraphic data combined with the spectral analysis performed on numerical data based on carbonate content variations of cores from well A, Campos Basin, reveal a periodicity related to the Milankovitch cycles. Benthic foraminiferal biofacies oscillations recognized in these cores have the same frequency and phase of long eccentricity cycles (400 Ka). Paleoceanographic changes (such as changes in ocean currents, water temperature and food supply) can modify the distribution and frequency patterns of foraminifera assemblages. However, the method used to interpret the biofacies, the geological context of the studied area and the proposed genetic model to explain the origin of these rhythmically patterned rocks, suggest that changes in foraminiferal biofacies are directly related to the paleobathymetry variations induced by glacio-eustatic oscillations of relative sea level . According to the proposed model, productivity-dilution cycles were instrumental in the origin of these marl-limestone couplets. During regressive phases, conditions were established to increase continental runoff to a bathyal setting. The increase of continental runoff with decrease of contribution of the main carbonate components led to the deposition of marlstone. During the transgressive phase, the relative reduction in clay input from continental sediments, favored a productivity growth of pelagic carbonate (calcareous nannofossil and planktonic foraminifera), which created conditions facilitating the deposition of limestone layers. The paleobathymetry oscillations, interpreted from the benthic foraminifera assemblage, and the formation of couplets, seems to be in phase with the transgressive-regressive cycles indicating a common cause to both processes.

    Full Text Available Tourmalines of intermediate schorl-dravite composition occur in iron formation (including metachert and tourmalinites, metasediments, calc-silicate and metabasic/intermediate rocks of the Morro da Pedra Preta Formation, a volcanic-sedimentary sequence of the Serra do Itaberaba Group (northeast of São Paulo City, southeastern Brazil. The Morro da Pedra Preta Formation is crosscut by quartz veins that contain both intermediate schorl-dravite and an alkali-deficient, Cr-(V-bearing tourmaline, in which the occupancy of the X-site is ϑ0.51Ca0.33Na0.15, characterizing it as intermediate to foitite and magnesiofoitite end-members. Mg# values for this tourmaline are higher than those for intermediate schorl-dravite. Raman spectroscopy also confirms the presence of two groups of tourmalines. Stable isotope data indicate sediment waters as fluid sources, rather than fluids from magmatic/post-magmatic sources. Delta18O compositions for tourmalines, host metachert, and quartz veins are similar, showing that fluid equilibration occurred during crystallization of both quartz and tourmaline. Syngenetic, intermediate schorl-dravite tourmalines were formed under submarine, sedimentary-exhalative conditions; amphibolite-grade metamorphism did not strongly affect their compositions. Younger tourmalines of compositions intermediate to foitite and magnesiofoitite reflect the composition of the host rocks of quartz veins, due to fluid percolation along faults and fractures that caused leaching of Cr (and V and the crystallization of these alkali-deficient, Cr-(V-bearing tourmalines.Na Formação Morro da Pedra Preta, seqüência vulcano-sedimentar do Grupo Serra do Itaberaba (São Paulo, Brasil, turmalinas de composição intermediária schorl-dravita ocorrem em formação ferrífera (incluindo turmalinito e metachert, metassedimentos, rochas cálcio-silicáticas e metabásicas a intermediárias.

    The Serra da Providência batholith includes the type area of the homonymous suite, the oldest rapakivi magmatic assemblage in the SW of the Amazonian craton (1.60-1.53 Ga). In the midwest portion of this massif, besides wiborgites/pyterlites and granophyric syenogranites, a leucosyenogranite facies and porphyritic rhyolites constitute new rock varieties recently described in that area. Usbnd Pb LA-MC-ICP-MS zircon ages of 1574 ± 9 Ma and 1604 ± 3 Ma, respectively, were obtained for these new varieties and confirm their link with the Serra da Providência magmatism, whereas the subvolcanic rocks are older than the main rock varieties and were formed in a precursor event. These granitic facies are metaluminous to peraluminous, alkali-calcic, A2-type, ferroan granites. Their FeOt/(FeOt + MgO) ratios vary from 0.83 to 0.98 and suggest that these rocks were crystallized from oxidized-to reduced-A-type magmas, where the leucosyenogranites and granophyric sienogranites tend to be formed under more reduced conditions. They show fractionated REE patterns with very pronounced to weak negative Eu anomalies. The presence of granophyric textures and miarolitic cavities in equigranular syenogranitic facies suggests that these rocks were formed at shallow crustal depths, lower than 3 km. Three samples of leucosyenogranite have silica contents higher than 75% and low K/Rb ratios (negative Eu anomalies a feature not observed in the equigranular gabbronorites. Porphyritic gabbronorites geochemical characteristics are similar to calc-alkaline basalts, whereas equigranular gabbronorites are similar to continental basalts. Petrographic, geochemical, and geological data of the felsic facies and the presence of associated mafic rocks corroborate the bimodal and post-collisional character of this magmatism. The occurrence of porphyritic rhyolites associated with shallow level plutonic granites in the Serra da Providência batholith reinforces the similarities between the Rondonian

    The Environmental Monitoring Project (PMA) aims to report environmental changes arising from drilling activity, in relation to the marine fauna. This project can also help in the monitoring of accidental spills. Since the professionals spend six hours of the day monitoring the ocean around the rigs, they can locate and identify oil stains, notify the responsible onboard, and also help in the monitoring of the oil stain. Such Project has been developed onboard a drilling unit working in Campos Basin. The results presented here were collected during the drilling activity in Bijupira and Salema fields, by Shell Brasil Petroleo Ltda, from July 13th to October 8th, 2011.

O experimento foi montado em casa de vegetação no Núcleo de Estudos e de Difusão de Tecnologia em Floresta, Recursos Hídricos e Agricultura Sustentável, município de Jerônimo Monteiro, Espírito Santo. A espécie vegetal utilizada foi a Coffea canephora Pierre ex A. Froehner, variedade Robusta Tropical (EMCAPER 8151, cultivada em vaso de 12 litros, por um período de 255 dias. As análises de crescimento foram realizadas 15 dias após o transplantio das mudas e no final do experimento, para determinação de matéria seca total e área foliar. O teor de umidade do solo na capacidade de campo varia com a tensão adotada em sua determinação. As maiores taxas de crescimentos relativo e absoluto do cafeeiro conilon foram obtidas quando a umidade do solo foi mantida na capacidade de campos determinada na tensão de 0,010 MPa no Latossolo Vermelho­Amarelo e de 0,006 MPa no Argissolo Vermelho-Amarelo. As menores taxas de crescimento da cultura foram observa­das na capacidade de campo determinada na tensão de 0,033 MPa, o que inviabiliza a sua adoção na estimativa da lâmina de irrigação utilizando-se a câmara de pressão de Richards.

  10. Pollination and reproductive biology of thirteen species of Begonia in the Serra do Mar State Park, São Paulo, Brazil

    Directory of Open Access Journals (Sweden)

    Graham Edward Wyatt

    2012-01-01

    Full Text Available The reproductive biology of 13 monoecious species of Begonia L. (Begoniaceae that occur in the Serra do Mar State Park, São Paulo, Brazil, was investigated. These species flower annually and present flowers with mostly white tepals, light and sweet odour, pollen as a reward but no nectar, numerous yellow stamens, and coiled yellow styles. Anthesis is diurnal and floral duration is long (6 - 15 days. The unusual appearance of pistillate flowers of these species supports the view that they are intersexual mimics of the staminate flowers. Despite consistently high levels of fruit-set, none of the 11 species tested proved to be apomictic. In contrast to earlier reports of self-compatibility in Begonia, self-pollinations of B. integerrima and B. itatinensis produced no fruits or seeds, and the complete absence of pollen tubes in the styles of self-pollinated flowers of B. integerrima suggests that the species is genetically self-incompatible. Flowers pollinated under natural conditions showed many pollen tubes that reached ovules, suggesting that adequate numbers of compatible pollen grains had been transported by pollinators. The principal pollinators were small bees of the Apidae and Halictidae. Ten species of bees were observed to visit eight species of Begonia, and pollen collection occurred by means of vibration, except for Trigona spinipes. Visits to rewarding staminate flowers were significantly more frequent than visits to unrewarding pistillate flowers. Duration of visits to pistillate flowers also was significantly shorter than the duration of visits to staminate flowers. We conclude that visits to pistillate flowers occur by mistake but with sufficient frequency to allow for successful reproduction in natural populations of these species.

    2006-01-01

    Full Text Available Entre os fatores que interferem na composição e na qualidade do vinho, destaca-se a safra vitícola, com suas variações climáticas. Com este objetivo, avaliou-se o efeito das safras de 1999, 2000 e 2001 na composição da uva, do mosto e do vinho Isabel da Serra Gaúcha. Nesse sentido, foram selecionados vinte e dois produtores de uva Isabel de onze municípios dessa região. Por ocasião da maturação, para as avaliações da uva e do mosto e a elaboração das microvinificações, foram colhidos 60kg de uva de cada viticultor. A safra vitícola interferiu significativamente no peso do cacho e da baga, mas não alterou a relação peso da ráquis/peso do cacho. No mosto, observaram-se diferenças em todas as variáveis, exceto para a relação degreesBrix/acidez total. No vinho, teve efeito na maior parte das variáveis avaliadas, com exceção aos cátions K, Mn, Cu e Rb. Em geral, a safra de 1999 foi a melhor, pois apresentou parâmetros mais adequados de acidez total, extrato seco, extrato seco reduzido, alcalinidade das cinzas, taninos, antocianinas e glicerol, variáveis essas que determinam a estrutura e a cor dos vinhos, importantes fatores para sua qualidade.

  12. Aspects of a conceptual groundwater flow model of the Serra Geral basalt aquifer (Sao Paulo, Brazil) from physical and structural geology data

    Fernandes, Amélia J.; Maldaner, Carlos H.; Negri, Francisco; Rouleau, Alain; Wahnfried, Ingo D.

    2016-08-01

    A preliminary conceptual model of groundwater flow was developed for the Serra Geral fractured basalt aquifer in order to assess the recharge to the underlying sandstone Guarani Aquifer System, one of the main aquifer systems in Brazil, which supplies water to millions of people. Detailed geological investigations included macroscopic description of the basalt flow units and the underlying sandstone. Petrographic and chemical analyzes were conducted on rock samples from outcrops and from five drilled boreholes. Detailed fracture surveys were accomplished at outcrops to characterize fracture sets and their potential to transmit water in the current tectonic context. Four basalt flows were identified in the Ribeirao Preto area and were named B1, B2, B3 and B4 (from oldest to youngest). The cooling process in flow B3 led to the generation of large sub-horizontal fractures at the contacts B2/B3 and B3-C/B3-E, which are the most transmissive structures. Groundwater flow in the basalt appears to be of the stratabound type because fractures, in general, do not propagate through the basalt vesicular layers, which behave as a regional hydraulic barrier for the vertical groundwater flow. However, it is proposed that the localized, continuous and closely spaced subvertical tectonic fractures, the only features that have the potential to crosscut the vesicular layers and the intertrappe sediments, can vertically connect the sub-horizontal transmissive fractures. Weathering and water seepage, observed in rock exposures, indicate that subvertical NE-trending fractures would be the most transmissive in the Ribeirao Preto area.

    Distance and discrete geographic barriers play a role in isolating populations, as seed and pollen dispersal become limited. Nearby populations without any geographic barrier between them may also suffer from ecological isolation driven by habitat heterogeneity, which may promote divergence by local adaptation and drift. Likewise, elevation gradients may influence the genetic structure and diversity of populations, particularly those marginally distributed. Bathysa australis (Rubiaceae) is a widespread tree along the elevation gradient of the Serra do Mar, SE Brazil. This self-compatible species is pollinated by bees and wasps and has autochoric seeds, suggesting restricted gene dispersal. We investigated the distribution of genetic diversity in six B. australis populations at two extreme sites along an elevation gradient: a lowland site (80-216 m) and an upland site (1010-1100 m.a.s.l.). Nine microsatellite loci were used to test for genetic structure and to verify differences in genetic diversity between sites. We found a marked genetic structure on a scale as small as 6 km (F ST = 0.21), and two distinct clusters were identified, each corresponding to a site. Although B. australis is continuously distributed along the elevation gradient, we have not observed a gene flow between the extreme populations. This might be related to B. australis biological features and creates a potential scenario for adaptation to the different conditions imposed by the elevation gradient. We failed to find an isolation-by-distance pattern; although on the fine scale, all populations showed spatial autocorrelation until ∼10-20 m. Elevation difference was a relevant factor though, but we need further sampling effort to check its correlation with genetic distance. The lowland populations had a higher allelic richness and showed higher rare allele counts than the upland ones. The upland site may be more selective, eliminating rare alleles, as we did not find any evidence for

    arte consiste en grabados, la mayoría de ellos aparentemente no figurativos en su estado actual, pero hay una imagen de un caballo y otra de un posible bisonte. Todos los grabados se localizan en el fondo del gran vestíbulo, a plena luz, en íntima relación con los depósitos de origen humano. El caballo y los grabados lineales asociados a él en las paredes de la cueva pueden atribuirse al Magdaleniense inferior o medio sobre la base de su estilo y de la altura practicable sobre las superficies de ocupación de estos períodos. Datables con mayor precisión son dos grupos de grabados lineales sobre un gran bloque que pueden asignarse al Magdaleniense inferior cantábrico, un período bien caracterizado por sus obras de arte mueble, como los omóplatos grabados, en El Mirón y en otros varios yacimientos regionales. El bloque cayó de la pared de la cueva, con su cara exterior yaciendo sobre el nivel 110, datado por radiocarbono en 16.130 ± 250 y 16.520 ± 40 BP. A partir de entonces se grabó su cara originalmente interior. A continuación, el bloque y sus grabados fueron progresivamente recubiertos por sedimentos del Magdaleniense medio, superior y final datados entre ca. 14.500- 12.000 BP. En suma, el arte descubierto y estudiado hasta la fecha en El Mirón puede atribuirse al Magdaleniense inferior y medio, aunque el yacimiento estuvo habitado por los humanos al menos desde el Paleolítico medio hasta época medieval. El artículo concluye situando el arte parietal de El Mirón en el contexto de las otras numerosas (pero peor datadas manifestaciones de arte rupestre de la cuenca del río Asón, en la Cantabria Oriental, que incluyen sitios tan notables como Venta de la Perra, Covalanas, La Haza y Cullalvera.

    The southern cattle fever tick, Rhipicephalus (Boophilus) microplus, is no doubt the most economically important ectoparasite of cattle globally. The inappropriate use of chemical acaricides has driven the evolution of resistance in populations of R. (B.) microplus. Anti-tick vaccines represent a technology that can be combined with acaricides in integrated control programs to mitigate the impact of R. (B.) microplus. The recombinant form of Bm86 antigen from the Campo Grande (rBm86-CG) strain of R. (B.) microplus was produced using the Pichiapastoris expression system to test its ability to immunoprotect cattle against tick infestation. Secretion of rBm86-CG by P. pastoris through the bioprocess reported here simplified purification of the antigen. A specific humoral immune response was detected by ELISA in vaccinated cattle. Immunoblot results revealed that polyclonal antibodies from vaccinated cattle recognized a protein in larval extracts with a molecular weight corresponding to Bm86. The rBm86-CG antigen showed 31% efficacy against the Campo Grande strain of R. (B.) microplus infesting vaccinated cattle. The rBm86-CG is an antigen that could be used in a polyvalent vaccine as part of an integrated program for the control of R. (B.) microplus in the region that includes Mato Grosso do Sul.

    The constant demand for Services Companies in Oil and Gas Industry to reduce the environmental impacts has led to a race in search of new cleaner technologies. Fluids with low toxicity are the target of research and development by the companies which are committed to ensure the aspects of quality, health, safety and environment from manufacturing up to the use in the final destination of these products. The replacement of these fluids is happening at a larger speed than in the past on the based in two factors: greater awareness on the part of these companies in relation to the environmental and by new environmental laws. The fluids systems used in fracturing operations are not an exception to this rule. Service companies today are in the process of replacing their formulations with systems less aggressive to the environment so-called 'green' systems. In this context the new technological developments of fracturing fluids are of fundamental importance to assist the new environmental requirements of both operators and government regulatory bodies and also to ensure better effectiveness of these products. This paper reports the research, development and application of new environmentally acceptable fracturing fluids technology, reviews the pioneering case histories in offshore operations and the benefits experienced in the Campos Basin - Brazil.

    Full Text Available As políticas de conservação da natureza em diversos paises estão cada vez mais ligadas à tomada de decisões ecológicas globais. Exemplos destas ligações variam entre a definição de prioridades e objetivos das políticas, à ação de ONG's ambientalistas internacionais, à existência de fundos e programas globais para o meio ambiente e o desenvolvimento sustentável, até as novas oportunidades econômicas representadas pelos mercados emergentes para serviços ecológicos globais e ''commodities ambientais''. Estas políticas freqüentemente conflitam com os direitos e as necessidades de diferentes populações locais, pois a implementação de áreas protegidas que excluem o homem recebe prioridade com respeito a outros modelos de conservação e uso sustentável da biodiversidade. O Brasil não faz exceção a esta regra. Hoje as políticas de conservação da natureza estão entrando em conflito direto com as políticas de preservação do direito à diferença cultural dos povos indígenas. Isto acontece a diversos níveis e em vários contextos locais diferenciados, desde a região Atlântica até a Amazônia e o Escudo das Guianas. A existência de fundos globais e suas prioridades podem contribuir para explicar estes conflitos, pois a ligação ecológica global contribui para redefinir as relações políticas nacionais e locais. O caso do Parque Nacional do Monte Roraima na Terra Indígena Raposa-Serra do Sol ilustra como modelos de conservação baseados na exclusão do homem, concebidos e implementados de cima para baixo, acirram conflitos preexistentes, políticos e sobre o direito à terra. Abordado através de um angulo diferente, este caso também aponta um possível caminho para soluções viáveis. Conversando, andando de canoa a remo e a pé com os índios Ingarikó na Serra do Sol, è possível perceber sua própria perspectiva cultural ecológica como elemento fundamental para a preservação dos recursos naturais

    is study was conducted in an area of 14 km in length oriented in the NNE direction by 7.3 km wide, covering the totality of the Serra do Carambei Granite and adjacent units. Located in the northern region of the Alagados dam, Parana State, this granite contains relatively high concentrations of K, eU and eTh, known since the 1970s through airborne and terrestrial gamma-ray spectrometry surveys. Recent radiochemical tests conducted on 61 samples of geological materials such as rocks (17 samples) and material of the weathering mantle and alluvial deposits (44 samples), confirmed the occurrence of radioactive anomalies in this granite, especially in thorium and uranium. The contents of K, eU and eTh obtained in gamma-ray spectrometry survey and radiochemical tests, converted to annual radiation dose (ARD), allowed to evaluate the intensity of natural radiation, whose levels relatively high in certain regions of the study area, can offer hazard to the local populations. The analysis and interpretation of data, as well the preparation of contour maps of K, eU and eTh were fundamental to understand the behavior and mobility of radionuclides in different environmental compartments of the area.

    Full Text Available We describe a new species of Atractus from Serra do Cipó, at the southeastern versant of Serra do Espinhaço, an inland mountain range nearly parallel to the Brazilian Atlantic coast. The new species is morphologically similar to A. paraguayensis and A. potschi with which it shares: 15 dorsal scale rows; white occipital region in juvenile specimens; dorsal ground color reddish pink to red (in life with alternate black transversal spots, blotches or transversal bands; seven upper and lower labial scales; ventrals and subcaudals creamish white; hemipenis slightly bilobed, semicapitate and semicalyculate. The new species differs from both taxa mainly on the basis of exclusive coloration characters (number and shape of transversal bands and hemipenial morphology (median face of the lobes without ornamentation, besides punctual meristic (number of ventral scales and maxillary teeth and morphometric (adult snout-vent length differences. Finally, we provide a discussion regarding the potential affinities of the new species and we redefine some Atractus species groups in order to better accommodate species sharing unique combinations of morphological characters.

    Full Text Available When rare is just a matter of sampling: Unexpected dominance of clubtail dragonflies (Odonata, Gomphidae through different collecting methods at Parque Nacional da Serra do Cipó, Minas Gerais State, Brazil. Capture of dragonfly adults during two short expeditions to Parque Nacional da Serra do Cipó, Minas Gerais State, using three distinct collecting methodsaerial nets, Malaise and light sheet trapsis reported. The results are outstanding due the high number of species of Gomphidae (7 out of 26 Odonata species, including a new species of Cyanogomphus Selys, 1873, obtained by two non-traditional collecting methods. Because active collecting with aerial nets is the standard approach for dragonfly inventories, we discuss some aspects of the use of traps, comparing our results with those in the literature, suggesting they should be used as complementary methods in faunistic studies. Furthermore, Zonophora campanulata annulata Belle, 1983 is recorded for the first time from Minas Gerais State and taxonomic notes about Phyllogomphoides regularis (Selys, 1873 and Progomphus complicatus Selys, 1854 are also given.

    Amber from the Campo La Granja mine in Chiapas, Mexico, is distinct from other sources of amber in Chiapas. Campo La Granja amber has distinct layers created by successive flows of resin with thin layers of sand on most surfaces. Aquatic and semi-aquatic arthropods are commonly found. Together these pieces of evidence suggest an estuarine environment similar to modern mangrove communities. The aquatic crustaceans are the most intriguing aspect of the biota. A large number of ostracods have been found in the amber-many with their carapaces open, suggesting that they were alive and submerged in water at the time of entombment. The only known examples of brachyuran crabs preserved in amber are found in the Campo La Granja amber. Amphipods, copepods, isopods, and tanaids are also members of the crustacean fauna preserved in amber.

    From the Lagrangian formalism as in classical field theory, the partial differential field equations for the propagation of a small perturbation in a continuous and homogeneous conducting media in a magnetic field is obtained. The specific Lagrangian is calculated and it is shown that the equation of motion is the wave equation. Finally, the law of energy conservation is obtained. [Spanish] A partir de un formalismo lagrangiano, como el de la teoria clasica de campos, se obtienen las ecuaciones diferenciales de campo para la propagacion de un pequeno disturbio en un medio conductor continuo y homogeneo que se mueve en presencia de un campo magnetico uniforme. Usando el mismo marco teorico se obtiene la ecuacion de balance de energia. Se calcula la lagrangiana especifica y se demuestra que la ecuacion de movimiento es la ecuacion en onda. Ademas, se obtiene la correspondiente ley de la conservacion de la energia.

    Full Text Available Field-work in the sierras near the sea-board of south-eastern Brazil continues to yield new or rare frogs. Four more of these forms are presented here. Two of them, both new, are put into the genus Eleutherodactylus, to which they belong by their general habitat, morphology, and also by the osteological characters. They differs from the known regional species of this genus only by the wider and shorter disks of some of the digits and the more lanceolate build. The other two species belong to the very little known genus Holoaden, established by MIRANDA RIBEIRO in 1920. One of them is his type-species, H. lüderwaldti, which continues to be very rare. The other, H. bradei, is new. It seems endemic to the Upper Itatiaia and is very plentiful there.O trabalho de campo nas serras vizinhas do nosso litoral continua a render anfíbios novos e raros. Aos já versados em publicações anteriores, acrescentamos as quatro espécies que formam o assunto so presente trabalho. Duas delas, ambas novas, pertencem ao gênero Eleutherodactylus, não só pelo seu hábitat e sua morfologia como também pelos caracteres osteológicos, verificados em exemplares diafanisados pelo meu ilustre colega Sr. ANTENOR LEITÂO DE CARVALHO e estudados por ambos os herpetólogos do Museu Nacional. Diferem das outras espécies do gênero pertencentes á fauna regional apenas pelo porte lanceolado e esgio e pelos discos mais curtos e mais largos de alguns dos dedos. As fêmeas da espéciemenor continham um certo número de ovos macrolecitais, característicos do gênero, cujo desenvolvimento é embrionário, sem fase larval. É interessante notar que, em duas delas, só os ovários direitos eram perceptíveis externamente. As outras duas espécies aqui versadas se filiam ao gênero Holoaden criado, em 1920, pelo nosso eminente predecessor, Professor ALIPIO DE MIRANDA RIBEIRO.

    Full Text Available É sabido que contar histórias é uma forma de comunicação humana que se estende aos dias de hoje. No entanto, tal prática se vê furtivamente ameaçada pelo desprendimento dos valores culturais tradicionais ante o florescer midiático. Objetivo: O presente trabalho postula o resgate da prática da contação de histórias no seio da comunidade rural de Jatobá, município de Janaúba/MG, através de um plano de intervenção pedagógico, como forma de valorizar as tradições e saberes do campo. Metodologia: Através de procedimentos de campo, foram avaliadas as perspectivas da tradição oral, partindo dos moradores mais antigos da localidade em cruzamento de dados com estudantes da escola local. Foi acionada uma entrevista para o primeiro grupo e um questionário para o segundo, buscando diagnosticar e refletir mais profundamente a realidade da tradição. Resultados: Evidenciou-se que a contação de histórias perde espaço no campo. As novas gerações têm pouco comprometimento e conhecimento das tradições e irrefletidamente se desconectam do núcleo cultural identitário de seu povo. A escola tem o papel de ressignificadora de práticas no resgate do berço cultural local. Considerações finais: A narrativa de histórias é uma atividade de potencial pedagógico inestimável, porém se vê em risco de desaparecimento, cumpre o ofício de seu resgate que se concatena ao resgate cultural e identitário de um povo e ao resgate do próprio indivíduo em seus manifestações e memória.

    The residual magnetism is a phenomenon in which the magnetic dipoles of a substance are oriented in a certain degree. On the other hand, when internal forces exist capable of aligning elementary magnetic dipoles of a material, a permanent magnet is obtained. Just as in a conductor or in a material, in the elements of a rotary electrical machine magnetic fields can be induced that produce a residual magnetism or magnetization. In the rotary electrical machines, the magnetization phenomenon causes serious problems, such as the generation of induced currents that propitiate the mechanical wear in bearings, collars, trunnions and inclusive in the shaft, by effects known as pitting, frosting and spark tracks, as well as erroneous readings in vibration and temperature sensors, that in some cases can cause the shut down of the machine. In this article are presented the general concepts on the residual magnetism in rotary electrical machines, the causes that originate it and the problems that arises, as well as the demagnetization of the components that have residual magnetic field. The results obtained by the area of Electrical Equipment of the Instituto de Investigaciones Electricas are revised, during the execution of activities related to the measurement and elimination of the residual magnetic field in rotary electrical machines. [Spanish] El magnetismo residual es un fenomeno en el que los dipolos magneticos de una sustancia se encuentran orientados en un grado determinado.

En las maquinas electricas rotatorias, el fenomeno de magnetizacion causa graves problemas, como la generacion de corrientes inducidas que propician el desgaste mecanico

From 55 wild hosts including six different species (Nasua nasua, Cebus spp., Cerdocyon thous, Myrmecophaga tridactyla, Tamandua tetradactyla and Dasyprocta aguti, 323 ticks were collected. Amblyomma ovale ticks were found solely on coatis, and Amblyomma nodosum was identified solely on anteaters. No ticks were found on capuchin monkeys. However, Amblyomma cajennense was found on all parasitized host species with the exception of capuchin monkeys. Giant anteaters displayed the highest infestation abundance, with a mean of 53 ticks∕animal. Environmental sampling yielded 166 adult A. cajennense ticks. The tick species found on domestic animals (Rhipicephalus (Boophilus microplus, R. sanguineus, Dermacentor nitens and A. cajennense were those typically found on these hosts in Brazil. The most prevalent tick species, A. cajennense, was found on both wild and domestic animals and was also prevalent in the environment. Thus, this tick species is the primary vector that allows pathogens to bridge wild and domestic animals in the Cerrado.Neste trabalho são descritas as espécies de carrapatos de animais selvagens e domésticos e do ambiente coletados por um ano na EMBRAPA Gado de Corte localizado na área urbana de Campo Grande, Mato Grosso do Sul, Brasil.

    In the hinterland of Rio de Janeiro city the rivers Guapiaçu, Macacu and Iconha originate in the Serra dos Órgãos mountain range and drain into the Atlantic Ocean. Since their channelization in the 1950s, higher flow velocities caused an incision of the rivers into the valley fills. These circumstances provide the possibility to study the alluvial deposits along the streams during low water level and allow conclusions on palaeoenvironmental change and landscape history. Sedimentological investigations of 13 exposures as well as AMS 14C measurements were carried out to investigate sediment properties and reconstruct the sedimentation history within the floodplains. These results enable to distinguish three different facies units. A late Pleistocene Unit I can be detected at the base of the observed exposures and consists of clast-supported fine to coarse gravels. It can be assumed that the gravel bodies were formed by a climatically induced erosional-depositional cycle within a braided river system. The gravels are overlaid by Unit II, a grayish to bluish loam mainly of mid-Holocene age. During generally drier climates these loams have been deposited during high water stages or flooding events as a splay facies proximal to the rivers. A reduced flow competence and relatively stable morphodynamic conditions are assumed for that period. Unit III accumulated in the late Holocene typically consists of several meters of planar or cross bedded sands to fine gravels, interfingered by loamy inclusions, buried peat bogs and organic debris. Fining-upward sequences can be frequently studied within Unit III which were completed by loamy sediments in the uppermost parts of the exposures. The increased flow competence from Unit II to Unit III seems to be a fluvial response to the increased humidity of the late Holocene as well as the enhancement of El Niño-Southern Oscillation (ENSO). Heavy rainfall likely caused higher sediment supply from the steep slopes as well as a

    Full Text Available The most recent and significant transformations of European landscapes have occurred as a consequence of a series of diffused, varied and often connected phenomena: urban growth and sprawl, agricultural intensification in the most suitable areas and agricultural abandonment in marginal areas. These phenomena can affect dramatically ecosystems' structure and functioning, since certain modifications cause landscape fragmentation while others tend to increase homogeneity. Thus, a thorough comprehension of the evolution trends of landscapes, in particular those linked to urban-rural relations, is crucial for a sustainable landscape planning.

    In this framework, the main objectives of the present paper are: (a to investigate Land Use/Land Cover (LULC transformations and dynamics occurred over the period 1955–2006 in the municipality of Serra San Bruno (Calabria, Italy, an area particularly representative of the Mediterranean mountainous landscape; (b to compare the settlement growth with the urban planning tools in charge in the study area; (c to examine the relationship between urban-rural gradient, landscape metrics, demographic and physical variables; (d to investigate the evolution of urban-rural gradient composition and configuration along significant axes of landscape changes.

    Full Text Available Ischnocnema (Brachycephalidae includes many species that are important members of the leaf litter frog communities in the Atlantic Rainforest of Brazil. Ischnocnema parva (Girard, 1853 is endemic to the Atlantic Rainforest biome and is restricted to the forests of southeastern Brazil. Currently, the available information about the ecology of I. parva is scarce. We studied the diet, the habitat use, reproduction and density of I. parva in an area of Atlantic Rainforest at the Concórdia mountain range, Rio de Janeiro. Individuals of I. parva were captured in April 2005 using different sampling methods: time constrained search (transects, plots of 5 x 5 m (25 m² on the litter, and pitfall traps with drift fences. We found 240 frogs; 35 females and 205 males. Females (mean SVL = 19.1 mm were significantly larger (F1,238 = 143.016, R² = 0.375, p < 0.001 than males (13.2 mm. The species preyed mainly on arthropods, with ants and isopods being the most important items, both showing high values of importance index (Ix = 50.0 and 26.7, respectively. Ischnocnema parva is a terrestrial species whose preferential microhabitat at the Serra da Concórdia was the litter of the forest floor (78.7%. The activity was predominantly crepuscular-nocturnal and the estimated density of I. parva was 24.9 ind/100 m². For the eight ovigerous females captured, the mean number of mature oocytes per female was 25 (range: 22-30 and the oocyte mean diameter was 1.11 mm (N = 40 oocytes. Oocyte number increased with female body size (R² = 0.504, F1,6 = 6.107, p < 0.05, N = 8, indicating that as females increase in size they produce larger clutches. Some ecological aspects such as diet and microhabitat use were similar to that observed for an insular population of I. parva, whereas reproductive traits differed. Thus, long term studies are necessary to understand the extent to which these differences are explained by environmental factors.

    Full Text Available As trilhas em áreas naturais são reconhecidas como meio de deslocamento entre o visitante e os atrativos turísticos. Assim, em áreas protegidas, ao mesmo tempo que proporciona ao visitante contato direto com a natureza, a visitação resulta em alterações ambientais como, dentre outros, a compactação do solo e erosão no leito das trilhas. O objetivo deste trabalho foi o de caracterizar a qualidade do solo na Trilha da Farofa, localizada no Parque Nacional da Serra do Cipó, município de Santana do Riacho, MG, Brasil. A trilha, que liga a sede do parque ao atrativo natural Cachoeira da Farofa, situada em escarpa rochosa quartzítica de grande beleza cênica, é a mais visitada e utilizada para alcançar o referido atrativo natural, além de servir para prática de caminhadas, ciclismo, cavalgada e do tráfego de veículos autorizados. Essa trilha apresenta impactos ambientais erosivos marcantes e compactação dos solos, este último, pouco visível a observações leigas. Para a caracterização dos impactos, efetuou-se o levantamento de perfis de solo no leito da trilha e no seu entorno, bem como medidas de resistência à penetração (penetrometria, com uso de penetrômetro de cone com anel dinamométrico e coleta de amostras de solo deformadas e indeformadas dos horizontes superficiais para estudos pedológicos. Os resultados demonstram que os solos do leito das trilhas são compactados em relação aos solos adjacentes e que estas precisam ser manejadas visando a conservação da biogeodiversidade associada, e a sua viabilidade enquanto meio de acesso à Cachoeira da Farofa e à escarpa rochosa quartzítica ali presente, o que evidencia a importância da utilização de atributos pedológicos para o manejo de trilhas, estimulando sua conservação através de práticas ambientalmente sustentáveis.

O ácaro ectoparasita Varroa destructor Anderson e Trueman (Acari: Varroidae pode ser um dos responsáveis por esse fato, principalmente como vetor de vírus. Neste estudo, avaliaram-se as taxas de infestação (TIs do ácaro V. destructor em abelhas africanizadas Apis mellifera L.

Em cada município, um apiário comercial foi selecionado para coleta de amostras de três colônias populosas (padrão Langstroth, totalizando 48 colônias amostradas. Aproximadamente 300 abelhas adultas localizadas na área de cria foram coletadas em cada colônia. As TIs variaram de 0.0 a 5.5%, níveis considerados baixos para causar danos significativos às colônias. As TIs mais baixas foram encontradas em municípios com clima mais ameno durante a estação avaliada (verão. Adicionalmente, cofatores como variações na disponibilidade de alimento entre os municípios e a variabilidade genética das abelhas podem interagir na interação entre parasita e hospedeiro. A variação nas TIs entre os municípios indica que, mesmo presente, a tolerância das abelhas africanizadas ao varroa pode variar drasticamente em uma pequena região, devido à dinâmica multifatorial de infestação do ácaro.

    PETROBRAS E and P department (up-stream segment) had assigned first contract for pipeline inspection using smart pigs in 1995. Up to this time only TRANSPETRO (down-stream segment) had an experience with those inspections mainly focused on first generation tools. On this contract, it was first time required high resolution tools, which had bigger defect detection capability and sizing accuracy as advantages but with higher cost. It was regarded necessary due to high costs involved on a virtual sub sea survey or repair. The investment was regarded fair as there is no way to establish correlation digs as well as normally done after on shore pipelines surveys. Actually the first internal inspection was carried out in 1997. From this period it has been realized the enormous importance on verifying all platforms installations and all procedures involving cleaning runs. We have taken many lessons from these inspections. Commissioning using all kinds of cleaning pigs (some was invented) that could be specially contracted on scaling removing jobs; diesel batch to make easy US pigs inspection, cleaning steps that should be gradual to allow receiving of debris without disturbing platforms process efficiency; special tools designed in-house to meet some specific installations requirements as limited pigability; were some issues that demanded efforts on this period. PETROBRAS/E and P through its Campos Basin Production Unit has been strongly involved on looking for solutions to keep its sub sea pipeline net integrity; a strategic asset that will guarantee the Brazilian development on oil and gas production.

    According to the Brazilian legislation, the Environmental Impacts Monitoring Plan is one of the requirements of the environmental licensing to offshore oil and gas production activities. The Monitoring Plan's structure is based upon sampling and evaluation of numerous parameter settings in water and sediment compartments, while the conclusion as to the existence or absence of impact is obtained after statistical analysis of the results. The aim of this work was to evaluate the methodological adequacy of monitoring and to calculate the statistical power of tests applied with the purpose to determine the reliability of their findings. Experiences in other countries like Australia have shown that this is an important instrument in preparing an effective environmental study regarding the detection of impacts. In Brazil, this is the first initiative to critically evaluate the results of reports of environmental monitoring originated from the licensing of hydrocarbons production activities. Campaign reports forwarded to the environmental agency in charge, i.e., the Brazilian Institute of Environment and Renewable Natural Resources (IBAMA), and the selected ventures are located in the Campos Basin and have different operating companies. The results were both relevant and concerning. All monitoring reports confirmed the absence of alterations or impacts on the biotic media for sediment compartments, but the greater statistical power did not exceed 25% for a great magnitude impact. Thus it was concluded that if the oil production activity has caused alterations or impacts to bentonic organisms, the carried out monitoring was inefficient to detect them even if they were of great magnitude. This analysis is expected to be an instrument for future changes in environmental licensing procedures e for the improvement of the environmental public management in Brazil. (author)

    Full Text Available This study aimed to compare the records of cases of diarrhea recorded in the Information System for Notifiable Diseases after the implementation of sewage system in Maraba Garden, Campo Grande, Brazil. The Garden Maraba had a degraded area, characterized by exhaustion open. We searched the records of SINAN in the period before and after the environmental changes that community. The results showed that there is an asymmetry in the indicators recorded, where it was hoped that the disease had greater control due to the deployment of exhaustion, especially in cases of diarrhea that persist at levels considerably. The conclusion points to the need to expand the study to address this knowledge gap, so important and what influence and compromises the quality of life of the population, especially in matters related to environmental education.

  17. Glacial changes and glacier mass balance at Gran Campo Nevado, Chile during recent decades

    2003-04-01

    Within the framework of the program Global Land Ice Measurements from Space (GLIMS) a glacier inventory of the Peninsula Muñoz Gamero in the southernmost Andes of Chile (53°S) has been generated using aerial photopgrahy and Landsat Thematic Mapper imagery. The Peninsula is partly covered by the ice cap of the Gran Campo Nevado (GCN), including several outlet glaciers plus some minor glaciers and firn fields. All together the ice covered areas sum up to 260 km2. GCN forms the only major ice body between the Southern Patagonia Icefield and the Strait of Magallan. Its almost unique location in a zone affected year-round by the westerlies makes it a region of key interest in terms of glacier and climate change studies of the west-wind zone of the Southern Hemisphere. A digital elevation model (DEM) was created for the area, using aerial imagery from 1942, 1984, and 1998 and a Chilean topographic map (1: 100 000). All information was incorporated into a GIS together with satellite imagery from 1986 and 2001. Delineation of glacier inflow from the central plateau of Gran Campo Nevado was accomplished using an automatic module for watershed delineation within the GIS. The GIS served to outline the extent of the present glaciation of the peninsula, as well as to evaluate the derived historic information. The comparison of historic and recent imagery reveals a dramatic glacier retreat during the last 60 years. Some of the outlet glaciers lost more than 20% of their total area during this period. In February and March 2000 a automatic weather station (AWS) was run on a nameless outlet glacier, inofficially Glaciar Lengua, of the Gran Campo Nevado Ice Cap. From the computed energy balance, it was possible to derive degree-day factors for the Glaciar Lengua. With data from the nearby AWS at fjord coast (Bahia Bahamondes) we computed ablation for the summer seasons of 1999/2000, 2000/2001 and 2001/2002. Ablation at 450 m a.s.l. sums up to about 7 m in 1999/2000, 5.5 m in 2000

    Full Text Available Las emociones han adquirido una importancia creciente en nuestra época, en todos los ámbitos de la sociedad. Esta revalorización de la dimensión afectiva de la persona se ha reflejado, a su vez, en su inclusión como objeto de estudio en investigaciones de numerosas ramas del saber. También dentro de los estudios en Comunicación, y en concreto en relación con la tecnología digital, existe un interés académico por las emociones. Por medio de una profunda revisión bibliográfica, en este trabajo se traza un mapa del campo de estudio en el que convergen las emociones y la tecnología digital; más concretamente, en el uso de Internet. En él se advierte un campo de investigación vibrante, amplio y complejo, en el que confluyen aproximaciones de diferente tipo, tanto en el plano teórico como en el metodológico. El artículo presenta un panorama de las investigaciones realizadas en esta materia, que abarca desde el estudio de las redes sociales como espacios de interacción en el que las emociones son expresadas, el contagio emocional a gran escala o el análisis de sentimientos en las plataformas digitales. Se concluye que la Red no sólo despierta emociones en sus usuarios y sirve de cauce para la expresión de los afectos, sino que también influye en el modo en que dicho afecto se modula y despliega, así como en la configuración de la identidad de la persona.

The present study aimed to identify the sandfly fauna and some of its ecological aspects in these two parks and their surrounding area to investigate Leishmania sp. vectors. The captures were undertaken monthly from January to December 2009, from 6:00 p.m. to 6:00 a.m., with automatic light traps installed in forests and peridomicile areas and with modified black/white Shannon traps in the peridomicile. A total of 12 species and 5,436 sandflies were captured: with automatic light traps (141, Shannon traps (5,219 and attempting to bite the researchers while they were conducting the collection in Shannon traps (76. Pintomyia fischeri and Migonemyia migonei were the most abundant species. Pi. fischeri predominated in all three kinds of captures (49%, 88.8% and 65.8%, respectively. Mg. migonei was the second most prevalent in Shannon traps (10.0% and attempting to bite the researchers (22.4%. Pi. fischeri females were significantly more attracted to black and those of Mg. migonei to white Shannon traps. A positive and significant correlation was observed between the numbers of Pi. fischeri and the mean of minimum relative humidity values on the fifteen days prior to capture, while there was a negative and significant correlation between the relative humidity on the capture day and the two most abundant species. The anthropophilia and high frequencies of Pi. fischeri and Mg. migonei suggest that both species may be transmitting ACL agents in this region.Casos humanos de leishmaniose tegumentar americana (LTA têm sido registrados na Serra da Cantareira, região da Grande São Paulo, onde se situam o Parque Estadual da Cantareira e o Parque Estadual Alberto Löfgren.
