    Triatoma jatai sp. nov. is the first new species of triatomine to be described in the state of Tocantins, in the northern region of Brazil. It was caught on rock outcrops in the wild environment and, more recently, invading homes. While T. jatai sp. nov. is morphologically similar to Triatoma costalimai, it is distinguished by its general colouring, differences in the blotches on the connexivum, wing size in females and external structures of the male genitalia. The type series has been deposited in the Entomological Collection and Herman Lent Collection, Oswaldo Cruz Institute-Oswaldo Cruz Foundation, Rio de Janeiro, Brazil. PMID:23828010

    Abstract The present study deals with the description of a new species of Rhinolekos. It can be distinguished from its congeners by having 31 vertebrae, the anterior portion of the compound supraneural-first dorsal-fin proximal radial contacting the neural spine of the 9th vertebra, the absence of transverse dark bands in the pectoral, pelvic and anal-fin rays, 24–28 plates in the dorsal series, the lack of odontodes on the ventral tip of the snout, the absence of accessory teeth, a greater prenasal length, a smaller head length, and by a greater snout length. Rhinolekos capetinga is restricted to the headwaters of the rio Tocantins and it is the first species of this genus in the Amazon basin. Additionally, we present a brief discussion of a biogeographic scenario that may explain the dispersal of the new species from the rio Paranaíba to the rio Tocantins basin. We suggest that the ancestral lineage of Rhinolekos capetinga reached the rio Tocantins from portions of the rio Paranaíba at the end of the Miocene, about 6.3 Mya (4.1–13.9 Mya 95% HPD), probably as a result of headwater capture processes among adjacent drainages.

  8. C and O isotope analysis of Paleo-Mesoproterozoic dolomitic limestones from Natividade Group - Tocantins, Brazil

    Natividade Group outcrops in southeastern Tocantins, a state in Brazil. Geologically, it corresponds to one of the sedimentary sequences that sets the Brasília fold and thrust belt. It represents a fining-upward sequence, where conglomerate prevails on the base, siltstones and limestones on the top. Initially, Natividade Group was believed to have been deposited in intracontinental rift environment, developed after a Rhyacian orogeny. This interpretation was supported by the fact that Natividade Group lays discordantly over the Rhyacian granitic basement and by existence of coeval and vicinal rocks from Araí Group. Araí Group is a well described rift-sequence, dated Staterian by volcanic intercalations. Natividade Group, on the contrary, has no intercalation of volcanic rocks and was recently interpreted as a platformal sequence by other authors. C and O isotope data from dolomitic limestones directly in contact with granitic basement were obtained in laminated and massif samples and corroborate this hypothesis. Samples are from a small hill called Morro do Mutum. Results found show ?18OV -SMOWvalues from+19.51 to +23.85 (?18OV -PDB between -11.01 and -6.63) and values of ?13CV -PDB are between -0.94 and +2.99. These data are coherent with values expected for marine carbonates, which ?13CV -PDBsignature is around zero, or slightly positive. Similarly, ?18OPDB resultsare also consistent with values observed in marine carbonates, although ?18OPDB data are more ambiguous, knowing its variation is wide in the various reservoirs. Differences between Natividade and Araí Gorups are important to estimate the paleogeography of the region. While the former corresponds to a platformal deposit, the latter filled rifts within the continent. This continent is the São Francisco craton, one of the landmasses that would collide in the Neoproterozoic, forming fold and thrust belts. Brasília belt is one of them.

    The Alto Tocantins watershed, located in the Brazilian Savanna (Cerrado biome), is under an intense land use and occupation process, causing increased pressure on natural resources. Pasture areas in the region are highly relevant to the rational use of natural resources in order to achieve economic and environmental sustainability. In this context, remote sensing techniques have been essential for obtaining information relevant to the assessment of vegetation conditions on a large scale. This study aimed to apply this tool in conjunction with field measurements to evaluate evapotranspiration (ET) against pasture degradation indicators. The SAFER algorithm was applied to estimate ET using MODIS images and weather station data from year 2012. Results showed that ET was lower in degraded pastures. It is noteworthy that during low rainfall period, ET values were 22.2% lower in relation to non-degraded pastures. This difference in ET indicates changes in the partition of the energy balance and may impact the microclimate. These results may contribute to public policies that aim to reduce the loss of the productive potential of pastures.

    Background Although leishmaniases are regarded as serious public health issues in the State of Tocantins, as consequence of the impact of environmental changes, small advances in taxonomic and ecological studies of Phlebotominae fauna are taking place in this state. The present study aimed to improve the knowledge about the sand flies, as well as about the aspects of the bioecology of leishmaniases vectors from Porto Nacional, a city that was directly impacted by the construction of Luís Eduardo Magalhães Hydroelectric Plant (HEP – Lajeado). Methodology/Principal Findings Sand flies were collected monthly using CDC light traps and Shannon traps for a period of 40 consecutive months, at different monitoring stations, where 7162 specimens were collected and 48 species were detected. Among the species found, 22 are first records in the state and seven are considered important vectors of leishmaniases. Lutzomyia longipalpis, the vector of American Visceral Leishmaniasis (AVL) showed higher frequency in urban compared to rural areas, and Nyssomyia whitmani, the vector of American Cutaneous Leishmaniasis (ACL), predominated in rural areas. The frequency and habits of sand fly vectors are discussed considering environmental characteristics and climatic factors. Conclusions/Significance The construction of dams requires a great amount of labor, therefore attracting people from elsewhere. Increased migration, without adequate structure, leads to bad living conditions in new and unplanned settlements. It also leads to deforestation associated with environmental impacts, which can facilitate the spread of leishmaniases. This study discusses the importance of Lu. longipalpis and Ny. whitmani on the transmission cycles of leishmaniases in Porto Nacional and the record of Bi. flaviscutellata in periurban area of the city.

    The diverse Brazilian AIDS epidemic has reached small cities and scant molecular information is available about the epidemic in Northern Brazil, where the incidence is growing. This study describes transmitted drug resistance and subtypes in the protease (PR) and reverse transcriptase (RT) regions among naive patients recruited in Palmas, the capital of Tocantins State, a newly built city in Northern Brazil. PR/RT regions were retrotranscribed from plasma HIV-1 RNA and 52 were sequenced after direct nested PCR. HIV-1 subtypes were assigned by phylogenetic analysis. Transmitted drug resistance was analyzed by the Calibrated Population Resistance tool Stanford Surveillance Drug Resistance Mutation. Most patients included (59.6%) were males, the median age was 30 years and were mainly referred because of heterosexual or homosexual unprotected sex. One male patient was from the Karajás indigenous tribe. The prevalence of transmitted resistance was 11.5% (CI 95%, 4.4-23.4%): nonnucleoside RT inhibitor mutations (n=3), nucleoside RT inhibitor mutations (n=2), and protease inhibitor mutations (n=1). Dual or triple class resistance was not observed. HIV-1 subtype B(PR)/B(RT) represented 78.8%, 5.8% were subtype C(PR)/C(RT), and 1.9% were subtype F1(PR)/F1(RT). Recombinant viruses represented 13.5% (07/52): B(PR)/F1(RT) (n=1), B(PR)/BF1(RT) (n=4), and C(PR)/CF1(RT) (n=2). This study about the AIDS epidemic in the recently founded city of Palmas/Tocantins in inland Northern Brazil shows moderate levels of transmitted drug resistance and the circulation of diverse recombinant viruses. This pattern is similar to what has been described in major metropolitan cities, suggesting the influence of imported cases from the south/southeast. Moreover these results indicate that patients from this setting should be monitored regarding transmitted drug resistance mutations. PMID:21417758

    Phlebotomine sandflies were captured in rural settlement and periurban areas of the municipality of Guaraí in the state of Tocantins (TO), an endemic area of American cutaneous leishmaniasis (ACL). Forty-three phlebotomine species were identified, nine of which have already been recognised as ACL vectors. Eleven species were recorded for the first time in TO. Nyssomyia whitmani was the most abundant species, followed by Evandromyia bourrouli, Nyssomyia antunesi and Psychodopygus complexus. The Shannon-Wiener diversity index and the evenness index were higher in the rural settlement area than in the periurban area. The evaluation of different ecotopes within the rural area showed the highest frequencies of Ev. bourrouli and Ny. antunesi in chicken coops, whereas Ny. whitmani predominated in this ecotope in the periurban area. In the rural settlement area, Ev. bourrouli was the most frequently captured species in automatic light traps and Ps. complexus was the most prevalent in Shannon trap captures. The rural settlement environment exhibited greater phlebotomine biodiversity than the periurban area. Ps. complexus and Psychodopygus ayrozai naturally infected with Leishmania (Viannia) braziliensis were identified. The data identified Ny. whitmani as a potential ACL vector in the periurban area, whereas Ps. complexus was more prevalent in the rural environment associated with settlements. PMID:23903972

    The RIBRAS facility (Radiactive Ion Beams in Brasil) is installed next to the 8 MV Pelletron Tandem of the Nuclear Physics Laboratory of the Institute of Physics of the University of São Paulo. It consists of two superconducting solenoids with maximum magnetic field of B=6.5T. Light radioactive ion beams are produced through transfer reactions, using solid or gaseous production targets of Be, LiF, 3He etc. The solenoids make a magnetic rigidity selection and the use of the two solenoids with a degrader between them allows the production of quite pure secondary beams. Beams of 6He, 8Li, 7Be, 10Be, 8B, 12B are currently produced and used to study elastic, inelastic, and transfer reactions on a variety of light, medium mass and heavy secondary targets. Some examples of reactions recently studied are presented below.

  6. Substitution for petroleum products in Brasil: Urgent issues

    de Araujo, J.L.; Ghirardi, A.

    1986-06-01

    Brazililan energy policy during the last decade has focused on the replacement of imported petroleum with domestic energy sources, combined with efforts at conservation. The substitution results, however, have been more spectacular by far. The strategy of replacement is based on two elements. first, to increase domestic petroleum exploration and production. Second, to promote non-petroleum fuels as alternatives to the industrial and transportation sectors, for the substitution of fuel oil and gasoline, respectively. A combination of the substitution strategy, the country's petroleum refining structure, and the composition of the substitution strategy, the country's petroleum refining structure, and the composition of demand, has resulted in large surpluses of both gasoline and fuel oil, while diesel has become the most used among petroleum products. The surpluses are not easily exportable because there is ample availability of fuel oil in the world market, and because the low octane number of the gasoline produced in Brasil is not compatible with the engines of cars elsewhere in the region and in the world. Furthermore, although gasoline might be upgraded, the question remains that prospects for the world market are not encouraging, and an export-based strategy does not seem justified in view of the growing surpluses. The objective of this analysis is to review the mechanisms of themajor petroleum-substitution programs currently in existence, identifying their past impact on the energy market and the possible consequences of changes in the goals and operating conditions of these programs, in the light of the new prospects for increased domestic oil production and self-sufficiency. 23 refs., 2 figs., 1 tab.

    This study addresses the formation of discourse about race and eugenics in texts and images published in O Brasil Médico, between 1928 and 1945. The documental analysis inspired on Foucault's theoretical and methodological perspectives, especially the concept of biopolitics, encountered references to the problems of eugenics amongst the Brazilian population, as well as a set of illustrations, mostly photographs of black people's bodies. A contradiction was identified, where a universalistic discourse about race was expressed at the same time that discourses about eugenics and biotypes revealed concerns about the degeneration of the formation of the Brazilian race. These discourses describe a Brazilian race with an idealized standard of physical and moral normality to serve as a model for the development and modernization of the nation. PMID:24346202

    The neotropical characid Salminus franciscanus is an economically valuable migratory fish whose populations have been drastically reduced in recent decades due to industrial and economic development in Brasil. To study its reproduction, a total of 283 adult specimens were captured in the Upper São Francisco River, downstream from the Três Marias dam, Minas Gerais, south-eastern Brasil, from August 2009 to July 2010. The gonadal maturity stages were determined from histological features of the gonads and gonadosomatic index (GSI). Gametogenesis was assessed by light and electron microscopy. For analysis of the oocyte's surface and fecundity, mature females were subjected to hormonal induction and oocyte stripping. Fish in resting (Stage 1) were common in all samplings, ripening/ripe and spawning (Stages 2 and 3) were predominant in October-November and December-January and post-spawning (Stage 4) occurred from December-January extending until April-May. The GSI followed the morphological changes of gonadal maturation, with a peak in October-November, when maximum GSI (7.08 in females and 3.46 in males) was achieved. From scanning electron microscopy, stripped oocytes showed a funnel-shaped micropyle and a simple oocyte surface arrangement, which is typical for non-adhesive eggs. Fecundity ranged from 160 to 440×10(3) oocytes per female and 129 to 175×10(3)oocytes/kg. The results of this study indicate that S. franciscanus reproduces in the Upper São Francisco River from October to January, exhibiting a total spawning pattern, non-adhesive eggs and high fecundity, providing support for aquaculture and conservation biology of this important neotropical characid fish.

    The association of body image dissatisfaction and obesity with physical activity is likely to differ according to gender. To investigate this hypothesis, we conducted a cross-sectional study among the ELSA-Brasil cohort members aged 34-65 years (n = 13,286). The body image dissatisfaction was present even among normal weight individuals of both sexes and was associated with lesser chances of practicing moderate physical activity in women and intense physical activity in men. Men and women with central obesity were less prone to practice physical activity of high or moderate intensity. Overweight and obese men were more likely to report vigorous physical activity while obese women were less likely to report this level of physical activity. Body images as well as nutritional status are related to physical activity in both sexes, but the association with physical activity differs by gender. PMID:26035664

  20. Geology, petrology and geochemistry of the "Americano do Brasil" layered intrusion, central Brazil, and its Ni-Cu sulfide deposits

    The "Americano do Brasil" Complex (ABC) is part of a cluster of coeval synorogenic mafic-ultramafic intrusions emplaced during the Brasiliano/Pan-African Orogenic Cycle in Brazil. The medium-sized ABC consists of interlayered dunite, peridotite, websterite, and gabbronorite. High Fo values of olivine (up to Fo88) and the crystallization sequence of the ABC (Ol + Chr ? Ol + Opx + Chr ? Cpx + Opx ? Opx + Pl + Cpx ? Opx + Pl + Cpx + Ilm + Mag) suggest crystallization from tholeiitic high-MgO parental magmas. Light rare earth element (REE)-enriched mantle-normalized REE profiles and ?Nd(T) values of +2.4 for cumulate rocks from the ABC suggest a depleted mantle source for the parental magma. The ABC Ni-Cu sulfide deposit (3.1 Mt at 1.12 wt.% Ni and 1.02 wt.% Cu) consists of three distinctively different orebodies (S1, S2, and G2). The S2 orebody, an unusual occurrence of stratiform massive sulfide hosted by dunite and peridotite in the interior of a layered intrusion, results from sulfides accumulated at the transient base of the magma chamber following a new influx of parental magma. The G2 orebody has an irregular and roughly cylindrical shape, consisting mainly of net-textured sulfides. The G2 orebody is hosted by peridotite and pyroxenite and located stratigraphically below the S1 orebody. S2 and G2 orebodies are characterized by low Cu/Cu + Ni ratios (mainly below 0.4). The S1 orebody, hosted by websterite and gabbronorite in the more fractionated sequence of the ABC, is a cluster of several irregular discontinuous orebodies of Ni-Cu disseminated sulfides. The sulfides of the S1 orebody have high Cu/Cu + Ni ratios (mainly between 0.5 and 0.8) and are highly depleted in PGE. The S1 orebody is interpreted to result from a later event of sulfide segregation in the magma chamber, possibly following the event that originated the G2 orebody. The bulk of ?34S values for sulfides of the ABC orebodies and their host rocks fall in the range of 0 ± 2‰. Higher ?34S values (between 3‰ and 5‰) are restricted to pyrite from xenoliths of gneiss located close to the S1 orebody and sulfides from the S1 orebody. Crustal xenoliths and chemical data (lithogeochemistry and sulfur isotope composition) provide evidence of crustal contamination of the igneous rocks hosting the S1 orebody, suggesting that sulfur saturation was induced by contamination with sulfide-bearing crustal rocks. The ABC deposit is an example of Ni-Cu sulfide mineralization hosted by synorogenic mafic-ultramafic intrusions. The S2 orebody is the first documented example of an economic stratiform massive sulfide orebody located within layered intrusions, expanding the opportunities for exploration of Ni-Cu sulfides in orogenic regions worldwide.

    Background Stress is a typical migraine trigger. However, the impact of negative life events on migraine activity is poorly studied. The aim of this study is to investigate the association between negative life events and migraine using data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) baseline assessment. Methods ELSA-Brasil is a multicenter cohort study conducted in six Brazilian cities. Baseline assessment included validated questionnaires for headache classification and the occurrence of five pre-specified negative life events (financial hardship, hospitalization other than for childbirth, death of a close relative, robbery and end of a love relationship), focusing on a 12-month period before evaluation. We built crude and adjusted logistic regression models to study the association between the occurrences of negative life events and migraine diagnosis and activity. Results We included 4,409 individuals with migraine and 4,457 participants without headache (reference). After adjustment for age, sex, race, income and educational level, we found that the occurrence of a negative life event (Odds ratio?=?1.31; 95% confidence interval?=?1.19 – 1.45) was associated with migraine. However, after stratifying with subgroup analyses, only financial hardship (Odds ratio?=?1.65; 95% confidence interval?=?1.47 – 1.87) and hospitalization (Odds ratio?=?1.47; 95% confidence interval?=?1.25 – 1.72) were independently associated with migraine. Further adjustment for a current major depression episode and report of religious activity did not significantly change the results. Considering migraine frequency as (a) less than once per month, (b) once per month to once per week, or (c) more than once per week, financial hardship and hospitalization remained significantly associated with migraine in all episode frequency strata, with higher odds ratios for higher frequencies in adjusted models. We also observed a significant association between the death of a close relative and the highest migraine frequency stratum (Odds ratio?=?1.38; 95% confidence interval?=?1.09 – 1.75) in full-adjusted model. Conclusions The occurrence of financial hardship and hospitalization had a direct and independent association with migraine diagnosis and frequency. The death of a close relative was also independently associated with the highest migraine frequency stratum. PMID:24993032

    Background Vascular dysfunction is an early expression of atherosclerosis and predicts cardiovascular (CV) events. Peripheral arterial tonometry (PAT) evaluates basal pulse amplitude (BPA), endothelial function (PAT ratio), and wave reflection (PAT?AIx) in the digital microvessels. In Brazilian adults, we investigated the correlations of PAT responses to CV risk factors and to carotid?femoral pulse wave velocity (PWV), a measure of arterial stiffness. Methods and Results In a cross?sectional study, 1535 participants of the ELSA?Brasil cohort underwent PAT testing (52±9 years; 44% women). In multivariable analyses, more?impaired BPA and PAT ratios were associated with male sex, higher body mass index (BMI), and total cholesterol/high?density lipoprotein. Higher age and triglycerides were related to higher BPA, whereas lower systolic blood pressure, hypertension (HTN) treatment, and prevalent CV disease (CVD) were associated with lower PAT ratio. PAT?AIx correlated positively with female sex, advancing age, systolic and diastolic blood pressures, and smoking and inversely to heart rate, height, BMI, and prevalent CVD. Black race was associated with lower BPA, higher PAT ratio, and PAT?AIx. Microvessel vasodilator function was not associated with PWV. Higher PAT?AIx was modestly correlated to higher PWV and PAT ratio and inversely correlated to BPA. Conclusion Metabolic risk factors are related to impaired microvessel vasodilator function in Brazil. However, in contrast to studies from the United States, black race was not associated with an impaired microvessel vasodilator response, implying that vascular function may vary by race across populations. PAT?AIx relates to HTN, may be a valid measure of wave reflection, and provides distinct information from arterial stiffness. PMID:25510401

    High blood pressure (HBP) is the leading risk factor for years of life lost in Brazil. Factors associated with HBP awareness, treatment and control need to be understood better. Our aim is to estimate prevalence, awareness, and types of anti-hypertensive treatment and to investigate the association of HBP control with social position. Data of 15,103 (54% female) civil servants in six Brazilian state capitals collected at the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) baseline (2008-2010) were used to estimate prevalence and cross-sectional association of HBP control with education, per capita family income and self-reported race, using multiple logistic regression. Blood pressure was measured by the oscillometric method. 35.8% were classified as presenting HBP; 76.8% of these used anti-hypertensive medication. Women were more aware than men (84.8% v. 75.8%) and more often using medication (83.1% v. 70.7%). Adjusted HBP prevalence was, in ascending order, Whites (30.3%), Browns (38.2%) and Blacks (49.3%). The therapeutic schemes most used were angiotensin-converting enzyme inhibitors, in isolation (12.4%) or combined with diuretics (13.3%). Among those in drug treatment, controlled blood pressure was more likely in the (postgraduate) higher education group than among participants with less than secondary school education (PR = 1.21; 95% CI: 1.14–1.28), and among Asian (PR = 1.21; 95% CI: 1.12–1.32) and ‘Whites (PR = 1.19; 95% CI: 1.12–1.26) compared to Blacks. Socioeconomic and racial inequality—as measured by different indicators—are strongly associated with HBP control, beyond the expected influence of health services access. PMID:26102079

  5. Earlier age at menarche is associated with higher diabetes risk and cardiometabolic disease risk factors in Brazilian adults: Brazilian Longitudinal Study of Adult Health (ELSA-Brasil)

    PubMed Central

    2014-01-01

    Objectives Early menarche has been linked to higher risk of type 2 diabetes in Western and Asian societies, yet whether age at menarche is associated with diabetes in Latin America, where puberty and diabetes may have different life courses, is unknown. We tested the hypothesis that earlier menarche is associated with higher diabetes risk in Brazilian adults. Methods We used data from 8,075 women aged 35-74 years in the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil) who had complete information on age at menarche, diabetes status, and covariates. Diabetes was defined based on self-reported physician diagnosis, medication use, and laboratory variables (fasting glucose, 2-hour glucose, and glycated hemoglobin). Poisson regression was used to generate risk ratios (RR) and 95% confidence intervals (CI). Results Menarche onset < 11 years [vs. 13-14 years (referent)] was associated with higher risk of diabetes (RR = 1.34; 95% CI: 1.14-1.57) after adjusting for sociodemographic factors, maternal education, maternal and paternal diabetes, and birth weight. This persisted after further control for BMI at age 20 years and relative leg length. Additionally, among those not taking diabetes medications, earlier menarche [<11 years vs. 13-14 years (referent)] was associated with higher % glycated hemoglobin (p < 0.001), alanine aminotransferase (p < 0.001), triglycerides (p < 0.001), C-reactive protein (p = 0.003), waist circumference (p < 0.001), and BMI measured at baseline exam (p < 0.001). Conclusion These findings support the hypothesis that earlier menarche is associated with greater risk for adult diabetes and cardiometabolic disease in the Brazilian context. PMID:24438044

    Introduction Observational studies have reported fairly consistent inverse associations between coffee consumption and risk of type 2 diabetes, but this association has been little investigated with regard to lesser degrees of hyperglycemia and other alterations in glucose homeostasis. Additionally, the association between coffee consumption and diabetes has been rarely investigated in South American populations. We examined the cross-sectional relationships of coffee intake with newly diagnosed diabetes and measures of glucose homeostasis, insulin sensitivity, and insulin secretion, in a large Brazilian cohort of middle-aged and elderly individuals. Methods We used baseline data from 12,586 participants of the Longitudinal Study of Adult Health (ELSA-Brasil). Logistic regression analyses were performed to examine associations between coffee consumption and newly diagnosed diabetes. Analysis of covariance was used to assess coffee intake in relation to two-hour glucose from an oral glucose tolerance test, fasting glucose, glycated hemoglobin, fasting and –2-hour postload insulin and measures of insulin sensitivity. Results We found an inverse association between coffee consumption and newly diagnosed diabetes, after adjusting for multiple covariates [23% and 26% lower odds of diabetes for those consuming coffee 2–3 and >3 times per day, respectively, compared to those reporting never or almost never consuming coffee, (p = .02)]. An inverse association was also found for 2-hour postload glucose [Never/almost never: 7.57 mmol/L, ?1 time/day: 7.48 mmol/L, 2-3 times/day: 7.22 mmol/L, >3 times/day: 7.12 mol/L, p<0.0001] but not with fasting glucose concentrations (p = 0.07). Coffee was additionally associated with 2-hour postload insulin [Never/almost never: 287.2 pmol/L, ?1 time/day: 280.1 pmol/L, 2–3 times/day: 275.3 pmol/L, >3 times/day: 262.2 pmol/L, p = 0.0005) but not with fasting insulin concentrations (p = .58). Conclusion Our present study provides further evidence of a protective effect of coffee on risk of adult-onset diabetes. This effect appears to act primarily, if not exclusively, through postprandial, as opposed to fasting, glucose homeostasis. PMID:25978631

    Background Chronic inflammation has been postulated to be one mediating mechanism explaining the association between low socioeconomic position (SEP) and cardiovascular disease (CVD). We sought to examine the association between life course SEP and C-reactive protein (CRP) levels in adulthood, and to evaluate the extent to which health-risk behaviors and metabolic alterations mediate this association. Additionally, we explored the possible modifying influence of gender. Methods and Findings Our analytical sample comprised 13,371 participants from ELSA-Brasil baseline, a multicenter prospective cohort study of civil servants. SEP during childhood, young adulthood, and adulthood were considered. The potential mediators between life course SEP and CRP included clusters of health-risk behaviors (smoking, low leisure time physical activity, excessive alcohol consumption), and metabolic alterations (obesity, hypertension, low HDL, hypertriglyceridemia, and diabetes). Linear regression models were performed and structural equation modeling was used to evaluate mediation. Although lower childhood SEP was associated with higher levels of CRP in adult life, this association was not independent of adulthood SEP. However, CRP increased linearly with increasing number of unfavorable social circumstances during the life course (p trend <0.001). The metabolic alterations were the most important mediator between cumulative SEP and CRP. This mediation path accounted for 49.5% of the total effect of cumulative SEP on CRP among women, but only 20.2% among men. In consequence, the portion of the total effect of cumulative SEP on CRP that was mediated by risk behaviors and metabolic alterations was higher among women (55.4%) than among men (36.8%). Conclusions Cumulative SEP across life span was associated with elevated systemic inflammation in adulthood.

    Background: Associations between major depressive disorder (MDD) and coronary heart disease (CHD) have been established, and these associations increase risk of future morbidity and mortality. Prior research has been carried out in high-income countries. Here we examine associations between the mood and anxiety disorders, and CHD in a large cohort at baseline from Brazil, a country facing a variety of challenges that may affect these associations. Methods: Participants included 15,105 civil servants aged 35 to 74 at baseline (2008–2010) from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). CHD (N = 721) included self-reported angina pectoris (n = 305), myocardial infarction (n = 259) and coronary revascularization (n = 239). Hierarchical logistic regression analyses were conducted to estimate odds ratios and confidence intervals. Results: Major findings indicate that comorbid MDD and anxiety disorders (n = 434) are associated with a threefold increase in CHD, MDD alone (n = 170) with a twofold increase in CHD, while generalized anxiety disorder alone (n = 1,394) and mixed anxiety and depression disorder (n = 1,844) – symptoms present, but diagnostic threshold not reached – are associated with a 1.5-fold increase in CHD, after full adjustment for covariates. Conclusion: The association with CHD is greatest in those with psychiatric comorbidity, while associations were also observed in MDD and generalized anxiety disorder without comorbidity. While findings are limited by the cross-sectional design of the study, given the known risks associated with comorbidity of the mood and anxiety disorders with CHD, findings reinforce the importance of comprehensive health assessment in Brazil.

    The author analyzes medical slang in Rio de Janeiro based on the view of interactive or live metaphor proposed by such authors as Black and Ricoeur, applied to puns and other jokes from medical work, with the goal of unveiling what physicians mean by this linguistic register. The article classifies medical slang in three broad areas, pertaining to the physician's relations with professional training and knowledge, patients, and health care services. Comparing his empirical material with previous studies focusing on hospital slang for patients, the author identifies, in addition, a range of slang terms for health care services themselves. The article points to interfaces between medical slang and the Brazilian "health hypercrisis" identified by Schramm. PMID:9878893

    Enrico Fermi was one of the greater physicists of the XX century. In 1934, he gave several lectures in Brazil. Invited by Theodoro Ramos to work in S\\~ao Paulo, he preferred to stay in Rome and went to the USA in 1938. However, Fermi recommended Gleb Wataghin to come in his place. Wataghin made history in Brazil, becoming one of the first Professors of the future S\\~ao Paulo University. Besides his relevance to the History of Science, Fermi eventually leaved an indelible mark on the creation and institutionalization of national scientific research due to the indication of Wataghin. Despite this fact, very little is known about Fermi's trip to Brazil. This work tries to reconstruct the fullest possible steps of the famous Italian physicist in our lands.

    The level and distribution of the genetic variability in 18 natural populations of Oryza glumaepatula that were collected from two Brazilian states were estimated using a set of 23 highly informative SSR markers. Samples comprising 78 and 117 individuals from populations of the states of Tocantins and Roraima, respectively, were evaluated in order to integrate and support previous studies that were carried out with populations of O. glumaepatula from Brazil. A total of 189 alleles were identified with an average of 8.22 alleles per locus. The 11 populations from Roraima presented, in combination, a higher genetic diversity (HE = 0.245) compared with that of the seven populations from Tocantins (HE = 0.212). All of the populations showed high and significant inbreeding values (mean f = 0.59); however, the mean was higher in Tocantins populations, indicating a higher gene flow in Roraima populations. The overall coefficient of genetic differentiation (FST) among the populations was high and significant (0.59) and was higher in Tocantins due to the isolation of each population, in contrast to Roraima, where gene flow occurred more frequently. The SSR panel used in this work resulted to be informative (polymorphism information content = 0.201) for assessing genetic structure in O. glumaepatula populations. PMID:25944782

    The identification of ecological and evolutionary mechanisms that might account for the elevated biotic diversity in tropical forests is a central theme in evolutionary biology. This issue is especially relevant in the Neotropical region, where biological diversity is the highest in the world, but where few studies have been conducted to test factors causing population differentiation and speciation. We used mtDNA sequence data to examine the genetic structure within white-backed fire-eye (Pyriglena leuconota) populations along the Tocantins River valley in the south-eastern Amazon Basin, and we confront the predictions of the river and the Pleistocene refuge hypotheses with patterns of genetic variation observed in these populations. We also investigated whether these patterns reflect the recently detected shift in the course of the Tocantins River. We sampled a total of 32 individuals east of, and 52 individuals west of, the Tocantins River. Coalescent simulations and phylogeographical and population genetics analytical approaches revealed that mtDNA variation observed for fire-eye populations provides little support for the hypothesis that populations were isolated in glacial forest refuges. Instead, our data strongly support a key prediction of the river hypothesis. Our study shows that the Tocantins River has probably been the historical barrier promoting population divergence in fire-eye antbirds. Our results have important implications for a better understanding of the importance of large Amazonian rivers in vertebrate diversification in the Neotropics. PMID:23442128

    The SE Brasilian Serras da Mantiqueira and do Mar topographic envelopes exhibit coast-parallel displacement gradients typical of linked normal faults in extending terrain. Between southern Curitiba and Cabo Frio, coast-perpendicular profiles show the distance from the maximum escarpment elevation to the likely location of the extended margin's flexural/rheological coupling point (Taper Break, or TB) is inversely correlative to the height of the escarpment. The correlation is similar to previously-published scaling relationships derived from Scandinavian and global datasets. Although Precambrian ductile shear zones guided brittle phase faulting during Mesozoic extension and Cenozoic margin uplift, the primary control governing fault reactivation and source-to-sink evolution of the SE Brasilian rifted margin seems rooted in crustal thinning. We see two lines of interest for petroleum exploration: Preferential reactivation of high angle faults at sharply-tapered margin sectors is expected to guide onshore to offshore sediment routing along margin-parallel corridors, and (should the TB-escarpment correlation be better validated with proposed analyses of high-quality marine geophysical datasets) a partial constraint upon architectural end member interpretations of deep crustal structure may be contemplated.

    An epidemiological survey in an endemic area for paracoccidioidomycosis in Ibiá town, Minas Gerais state, Brazil was carried out. For this, we used a standard form for each household and intradermal antigens of histoplasmin and paracoccidioidin. Out of 194 individuals, 109(56%) were engaged in the survey showing reactivity of 44% and 49.5% for these antigens respectively. The reactivity to paracoccidioidin was observed in 50% of children below ten years. Individuals who revealed reactivity to paracoccidiodin with prior history of coffee growing activities, and those reporting the grain collection as the main work, showed statistically significant association p = 0.0092, p = 0.0007 and p = 0,01 respectively. These results could suggest that activities related to coffee crops, may favour the transmission of Paracoccidioides brasiliensis, specially among the grain collectors. In addition, the reactivity for histoplasmin antigen, suggest that this region is endemic for both fungi. PMID:18473521

    Euryhaliotrema dontykoleos n. sp. (Monogenoidea, Polyonchoinea, Dactylogyridae) is described based on specimens collected from the gills of Pachyurus junki (Teleostei, Sciaenidae, Pachyurinae) in the Rio Tocantins and its tributaries, State of Tocantins, Brazil. The new species, the first species of Monogenoidea reported from a pachyurine, is easily differentiated from its congener by the presence of toothlike projections in the border of the vaginal opening and by having a trapezoidal anteromedial projection on the ventral bar. Phylogenetic analysis indicates that the new species is not a member of the clade that includes the Euryhaliotrema spp. from Plagioscion spp., a second lineage of freshwater sciaenids in South America. Euryhaliotrema dontykoleos shares an immediate ancestor with the clade formed by parasites infecting marine Paralonchurus spp., (Sciaenidae), and those of Plagioscion spp. PMID:16419743

    A molecular phylogenetic analysis based on mitochondrial 16S ribosomal DNA and Control Region sequences from native and introduced populations was undertaken, in order to characterize the introduction of Cichla (peacock bass or tucunaré) species in Brazil. Mitochondrial DNA haplotypes found in introduced fish from Minas Gerais state (southeastern Brazil) clustered only with those from native species of the Tocantins River (Cichla piquiti and C. kelberi), thereby suggesting a single or, at most, few translocation acts in this area, even though with fish from the same source-population. Our study contributes to an understanding of the introduction of Cichla in regions of Brazil outside the Amazon basin, and adds phylogenetic data to the recently describe Cichla species, endemic from the Tocantins-Araguaia basin.

    Anopheles darlingi Root is the principal vector of Plasmodium in Brazil, but its biological variability is not well known. Morphometric analyses of scanning electron microscopy images of the eggs of An. darlingi were conducted using individuals collected in nine states of Brazil (Acre, Amapá, Espírito Santo, Pará, Paraná, Rio de Janeiro, Rondônia, São Paulo, and Tocantins). Ten attributes of the eggs (seven continuous variables and three discrete variables) were respectively measured or counted and analyzed to determine if populations from different geographical regions or biomes could be distinguished. Univariate analysis showed that the eggs from Espírito Santo were the narrowest whereas representatives from Tocantins populations had the smallest floats. Results of multivariate analyses of continuous variables showed that the first principal component (PC1), mainly represented by all four float attributes, helped to differentiate populations. The second principal component (PC2) comprised roughly the length and width of the egg. PC1 of discrete variables corresponded to the number of ribs on the float whereas PC2 was approximately equivalent to the number of discs on the micropyle. Based on those variables (continuous and discrete separately), multivariate discriminant analysis indicated that eggs from individuals collected in Tocantins were distinct from the other populations. Among sampled localities, the one from the state of Tocantins was situated within the Cerrado biome whereas the locality from São Paulo state was at the border of Cerrado, within a transition zone of the Atlantic Forest biome. Generally, the climate in the Cerrado biome was more arid than in areas of the Amazon and Atlantic Forest biomes, and the temperature had the highest range. Coincidentally, based on morphometric data, cluster analysis distinguished the population from Cerrado, Tocantins from all other populations. Results of multiple regression analysis of the variables showed no correlation between egg variables and latitude or climatic variables. We concluded that eggs were polymorphic and that some morphological patterns were regional. Although no environmental influence on the egg attributes was unequivocally detected, a potential association cannot be entirely discarded. Consequently, we hypothesize that morphological traits of the immature stages, especially from the eggs, convey evolutionary information regarding to this species. PMID:25077432

    We evaluated seasonal species presence and richness, and abundance of medium and large sized mammalian terrestrial fauna in the "Mário Viana" Municipal Biological Reserve, Nova Xavantina, Mato Grosso, Brazil. During 2001, two monthly visits were made to an established transect, 2,820 m in length. Records of 22 mammal species were obtained and individual footprint sequences quantified for seasonal calculation of species richness and relative abundance index (x footprints/km traveled). All 22 species occurred during the rainy season, but only 18 during the dry season. Pseudalopex vetulus (Lund, 1842) (hoary fox), Eira barbara (Linnaeus, 1758) (tayra), Puma concolor (Linnaeus, 1771) (cougar) and Hydrochaeris hydrochaeris (Linnaeus, 1766) (capybara) were only registered during the rainy season. The species diversity estimated using the Jackknife procedure in the dry season (19.83, CI = 2.73) was smaller than in the rainy season (25.67, CI = 3.43). Among the 18 species common in the two seasons, only four presented significantly different abundance indexes: Dasypus novemcinctus Linnaeus, 1758 (nine-banded armadillo), Euphractus sexcinctus (Linnaeus, 1758) (six-banded armadillo), Dasyprocta azarae Lichtenstein, 1823 (Azara's Agouti) and Tapirus terrestris (Linnaeus, 1758) (tapir). On the other hand, Priodontes maximus (Kerr, 1792) (giant armadillo) and Leopardus pardalis (Linnaeus, 1758) (ocelot) had identical abundance index over the two seasons. Distribution of species abundance in the sampled area followed the expected pattern for communities in equilibrium, especially in the rainy season, suggesting that the environment still maintains good characteristics for mammal conservation. The present study shows that the reserve, although only 470 ha in size, plays an important role for conservation of mastofauna of the area as a refuge in an environment full of anthropic influence (mainly cattle breeding in exotic pasture).

    In the last decades, coagulase-negative staphylococci (CoNS), especially Staphylococcus epidermidis have become an important cause of bloodstream infections. In addition, rates of methicillin-resistance among CoNS have increased substantially, leading to the use of glicopeptides for therapy. The objective of this study was to evaluate eleven consecutives clinically relevant cases of oxacillin-resistant CoNS bacteremia in a general hospital localized in São Paulo city, Brazil. Five different species were identified by different phenotypic methods, including S. epidermidis (5), S. haemolyticus (3), S. hominis (1), S. warneri (1) and S. cohnii subsp urealyticus (1). A variety of Pulsed Field Gel Electrophoresis profiles was observed by macrorestriction DNA analysis in S. epidermidis isolates, but two of three S. haemolyticus isolates presented the same profile. These data indicated the heterogeneity of the CoNS isolates, suggesting that horizontal dissemination of these microorganisms in the investigated hospital was not frequent. One S. epidermidis and one S. haemolyticus isolates were resistant to teicoplanin and susceptible to vancomycin. The selective pressure due to the use of teicoplanin in this hospital is relevant.

    Soares, J.E.; Berrocal, J.; Fuck, R.A.; Mooney, W.D.; Ventura, D.B.R.

    2006-01-01

    A two-dimensional model of the Brazilian central crust and upper mantle was obtained from the traveltime interpretation of deep seismic refraction data from the Porangatu and Cavalcante lines, each approximately 300 km long. When the lines were deployed, they overlapped by 50 km, forming an E-W transect approximately 530 km long across the Tocantins Province and western Sa??o Francisco Craton. The Tocantins Province formed during the Neoproterozoic when the Sa??o Francisco, the Paranapanema, and the Amazon cratons collided, following the subduction of the former Goia??s ocean basin. Average crustal VP and VP/VS ratios, Moho topography, and lateral discontinuities within crustal layers suggest that the crust beneath central Brazil can be associated with major geological domains recognized at the surface. The Moho is an irregular interface, between 36 and 44 km deep, that shows evidences of first-order tectonic structures. The 8.05 and 8.23 km s-1 P wave velocities identify the upper mantle beneath the Porangatu and Cavalcante lines, respectively. The observed seismic features allow for the identification of (1) the crust has largely felsic composition in the studied region, (2) the absence of the mafic-ultramafic root beneath the Goia??s magmatic arc, and (3) block tectonics in the foreland fold-and-thrust belt of the northern Brasi??lia Belt during the Neoproterozoic. Seismic data also suggested that the Bouguer gravimetric discontinuities are mainly compensated by differences in mass distribution within the lithospheric mantle. Finally, the Goia??s-Tocantins seismic belt can be interpreted as a natural seismic alignment related to the Neoproterozoic mantle domain. Copyright 2006 by the American Geophysical Union.

    1999-11-01

    The Tucurui Dam, which blocked the Tocantins River in 1984 in Brazil's eastern Amazonian state of Para, is a continuing source of controversy. Most benefits of the power go to aluminum smelting companies, where only a tiny amount of employment is generated. Often presented by authorities as a model for hydroelectric development because of the substantial power that it produces, the project's social and environmental impacts are also substantial. Examination of Tucurui reveals a systematic overestimation of benefits and underestimation of impacts as presented by authorities. Tucurui offers many as-yet unlearned lessons for hydroelectric development in Amazonia.

    The Tetraodontidae are an Acantomorpha fish family with circumglobal distribution composed of 189 species grouped in 19 genera, occurring in seas, estuaries, and rivers between the tropical and temperate regions. Of these, the genus Colomesus is confined to South America, with what have been up to now considered only two species. C. asellus is spread over the entire Amazon, Tocantins-Araguaia drainages, and coastal environments from the Amazon mouth to Venezuela, and is the only freshwater puffers on that continent. C. psittacus is found in coastal marine and brackish water environments from Cuba to the northern coast of South America as far south as to Sergipe in Brazil. In the present contribution we used morphological data along with molecular systematics techniques to investigate the phylogeny and phylogeography of the freshwater pufferfishes of the genus Colomesus. The molecular part is based on a cytochrome C oxidase subunit I dataset constructed from both previously published and newly determined sequences, obtained from specimens collected from three distinct localities in South America. Our results from both molecular and morphological approaches enable us to identify and describe a new Colomesus species from the Tocantins River. We also discuss aspects of the historical biogeography and phylogeography of the South American freshwater pufferfishes, suggesting that it could be more recent than previously expected.

    Large layered intrusions of the Porto Nacional area include two distinctively different groups. Mafic intrusions located west of the Tocantins River (Group 1) follow a tholeiitic (Fenner-trend) fractionation trend characterized by olivine compositions from moderately primitive (Fo 68) to highly fractionated (Fo 07). Zircon fractions of an olivine gabbronorite from a Group 1 intrusion yield a U-Pb concordia age of 526 ± 5 Ma. Highly variable TDM ages and negative ?Nd(530 Ma) values of samples from this Group 1 intrusion indicate crystallization in ca. 530 Ma from a magma highly contaminated with older crustal rocks. The layered intrusions located east of the Tocantins River (Group 2) have a large proportion of ultramafics (mainly wehrlite) and follow an Opx-free crystallization sequence. The compositional variation of olivine (Fo 85-84) and Cpx (En 49-45) of cumulates from Group 2 intrusions indicates moderately primitive compositions and very limited fractionation. Sm-Nd isotopic data for Group 2 intrusions are highly scattered and do not yield a crystallization age. Highly variable TDM ages and negative ?Nd(530 Ma) values suggest that the parental magmas of Group 2 intrusions were heterogeneously contaminated with old crustal material. These two petrologically distinct groups of layered intrusions open new opportunities for exploration for Ni-PGE deposits in central Brazil.

    Babassu is considered the largest native oil resource worldwide and occurs naturally in Brazil. The purpose of this study was to evaluate the potential of babassu nut residues (epicarp, mesocarp and endocarp) for bioenergy use, especially for direct combustion and charcoal production. The material was collected in the rural area of the municipality of Sítio Novo do Tocantins, in the state of Tocantins, Brazil. Analyses were performed considering jointly the three layers that make up the babassu nut shell. The following chemical characterizations were performed: molecular (lignin, total extractives and holocellulose), elemental (C, H, N, S and O), immediate (fixed carbon, volatiles and ash), energy (higher heating value and lower heating value), physical (basic density and energy density) and thermal (thermogravimetry and differential thermal analysis), besides the morphological characterization by scanning electron microscopy. Babassu nut residues showed a high bioenergy potential, mainly due to their high energy density. The use of this biomass as a bioenergy source can be highly feasible, given their chemical and thermal characteristics, combined with a low ash content. Babassu nut shell showed a high basic density and a suitable lignin content for the sustainable production of bioenergy and charcoal, capable of replacing coke in Brazilian steel plants.

    The blue-fronted Amazon (Amazona aestiva) is a widely distributed Neotropical parrot and one of the most captured parrots in nature to supply the illegal trade of wild animals. The objectives of the present study were to analyze the genetic structure of A. aestiva to identify management units and support conservation planning and to verified if A. aestiva populations have undergone a recent bottleneck due to habitat loss and capture for the pet trade. The genetic structure was accessed by analyzing six microsatellite loci in 74 individuals of A. aestiva, including samples from the two subspecies (A. a. aestiva and A. a. xanthopteryx), from five populations: four in Brazil and one in Argentina. A significant genetic differentiation (theta = 0.007, p = 0.005) could be detected only between the most distant populations, Tocantins and Argentina, localized at the northeast and southwest limits of the sample sites, respectively. There was no evidence of inbreeding within or between populations, suggesting random mating among individuals. These results suggest a clinal distribution of genetic variability, as observed for variation in plumage color of the two A. aestiva subspecies. Bottleneck analysis did not show a recent reduction in population size. Thus, for the management and conservation of the species, the populations from Argentina and Tocantins should be considered as different management units, and the other populations from the center of the geographical distribution as another management unit.

    The main anthropogenic sources in the environment are fertilizers, pesticides, biomass burning, vehicle emissions, and disposal of urban and industrial waste. Vinasse is characterized as a residual of sugarcane distillery effluent with high concentrations of potassium and organic matter. The environmental impact caused by its use in the vinasse is modification chemical and physical properties in the soil and water. For this, the isotopic technique can be a powerful tool to understand the biogeochemical cycling of light elements (C and N). Some environmental studies have been conducted involving isotopic characterization of Carbon and Nitrogen in soil. Several soils cultivated with sugarcane of different regions of São Paulo state, Brazil, were analyzed to perform the isotopic characterization. The study area was selected where soil management is by mechanical harvesting of sugarcane and vinasse application. The area was divided into three parts: control (without cultivation); after mechanical harvesting of sugarcane; after mechanical harvesting of sugarcane and vinasse application. Three days after the harvest of sugarcane the vinasse was applied and sampling of soil surface was carried out in two periods of 7 and 30 days after application of vinasse. The isotopic determination in the sample soil and concentration of C and N was by IRMS, Thermo Delta Plus, allowing simultaneous determination of 13C/12C isotope ratios (?13C) and 15N/14N (?15N). The results of the C and N concentration in the vinasse applied were average values 2.52% and 0.02% and isotopic values of 13C and 15N were -14.1‰ and 5.2‰. The results for the C concentration of the three areas in two periods showed values around 0.86 to 1.01%. The 13C isotopic values were -16.8 to -15.0‰, demonstrating the predominant cultivation in the region in relation to ?13C values of C4 plant (sugarcane). The results of N analysis were 0.08 to 0.10% and 15N isotope analysis, showing values ranging from 7.9 to 8.5‰. No significant variation in concentration of N and C in three study areas was observed. Considering 13C and 15N isotopic characterization independent of management, there was noted no isotopic fractionation by microbial activity. The results evidenced that the addition of vinasse in the soil did not increase the concentration of C and N does not represent a source of C and N. Furthermore, the isotopic technique can be applied in studies involving biogeochemical cycling, aiming to identify progress or setbacks in the quality of soil and possible impact in ecosystem.

    The present work studies the role of international cooperation on the Brazilian scientific and technological (S&T) development process, based on the case of the cooperation among Brazil and the European Organization for Nuclear Research (CERN). It starts at an analysis of the national strategies for S&T development since the 1970’s. The studies lead to a suggestion of a new strategic approach of a system beginning starting at activities of international S&T interchange and collaborations as initial stage that lead to International Cooperation, seen as the only one capable of create S&T development. The case of the Brazilian activities at CERN shows that International Cooperation generates S&T development only with long term assured financial and institutional support of the Government. The results point to the assumption that International Cooperation is an essential element for elaboration and execution of public policies that aim national development on science and technology.

  17. Magnetic fabric and emplacement mechanisms in a co-mingled mafic and felsic magma chamber: the Espinharas granite (Borborema Province, NE Brasil)

    The Espinharas granite is a co-mingled mafic and felsic magmatic complex forming part of the widespread Brasiliano plutonism that affected the Borborema Province during the Neoproterozoic. Syenogranite is mixed and mingled with diorite generating a range of aluminous shoshonitic hybrid rocks containing mafic microgranular enclaves (MME) of various shapes and orientations. Geochemical modelling shows that the pluton originated by upper-mantle magma underplating and fault-assisted intrusion of diorite, which would supply heat for partial melting of the crust and formation of syenogranite. The Espinharas granite comprises syenogranites and diorites associated with quartz-monzonites, monzodiorites and syenites mainly deformed in the magmatic state. The pluton is emplaced within Paleoproterozoic augen gneisses from the basement and is bounded by high-temperature NE-trending mylonitic shear zones at its western and eastern borders. To the south, the pluton is in contact with the E-trending high-grade transpressional Patos shear zone. Magmatic foliations can be observed throughout the syenogranite and in the felsic rocks, being defined by a SPO of feldspars and quartz. However, they appear to be absent in the diorite. The microgranular enclaves display irregular contacts with the host syenogranite and may be often aligned in agreement with the magmatic foliation; they are also randomly dispersed and disrupted by monzo- to syenogranitic veins. The Anisotropy of Magnetic Susceptibility (AMS) technique was employed in order to investigate the mechanical relationships between mingled mafic and felsic magmas, as well as their emplacement mechanisms. Susceptibilities are usually high (k > 1.3 mSI), suggesting that Ti-magnetite is the main carrier of the magnetic signal. The magnetic lineation plunges shallowly to NE, parallel to the pluton main elongation axis. Zircons from diorite and syenogranite yield U-Pb (SHRIMP) ages of ~ 620 Ma, which are attributed to the crystallization of the granite and are younger than the main metamorphic event in the Seridó Belt (~ 575 Ma). These data suggest that the magnetic fabric of the Espinharas granite records the high-temperature deformation observed in the Seridó Belt. This deformation was active during a prolonged time range (~ 100 Ma) in a hybrid magmatic chamber emplaced in the middle- to shallow continental crust. These conditions indicate that the Patos shear zone controlled the development of the magmatic- to solid-state fabric of the Espinharas granite, highlighting the contribution of strain partitioning in the mechanical mingling of magmas in the continental crust.

    Abnormal glucose metabolism preceding overt diabetes is associated with increased cardiovascular risk. Whether novel biomarkers are useful to identify this condition is unclear. The objective was to investigate associations of biomarkers of atherogenesis with plasma glucose within non-diabetic range. 998 participants (35-54 years) of the Brazilian Longitudinal Study of Adult Health without diabetes or cardiovascular disease were classified as normal glucose tolerance (NGT), impaired fasting glycemia (IFG) and impaired glucose tolerance (IGT). Traditional risk factors and markers of atherogenesis were evaluated among groups and across plasma glucose concentrations. IFG and IGT had worse profile considering traditional cardiovascular risk factors than the NGT group, although these values were within the reference range. NGT, IFG and IGT groups differed (medians and interquartile intervals) regarding transforming growth factor-?1 [12.2 (6.4-22.3), 16.8 (8.4-26.5), and 15.5 (8.0-26.1)pg/mL, p<0.05], C-reactive protein [1.1 (0.6-2.9), 1.2 (0.6-2.7), and 1.4 (0.8-3.7)ng/mL, p<0.001] and monocyte chemoattractant protein-1 [35.9 (21.2-57.8), 32.2 (18.7-55.8), and 34.1 (18.6-52.4)pg/mL, p<0.05]. TGF-?1 and E-selectin concentrations increased while MCP-1 decreased across quartiles of fasting plasma glucose. C-reactive protein increased with increments in 2-h plasma glucose. In linear regression, TGF-?1 was independently associated with fasting plasma glucose, and C-reactive protein with 2-h plasma glucose after adjustments. In conclusion, association of TGF-?1, E-selectin, C-reactive protein and MCP-1 with slight elevations in glycemia may be anticipating alterations in traditional cardiovascular risk factors. Independent association of TGF-?1 with plasma glucose suggests that this may be useful to identifying atherogenic process, deserving further investigation on the prediction of cardiovascular outcomes.

    Excavation of Toca do Serrote das Moendas, in Piauí state, Brazil revealed a great quantity of fossil wild fauna associated with human remains. In particular, fossils of a cervid (Blastocerus dichotomus) were found, an animal frequently pictured in ancient rock wall paintings. In a well-defined stratum, two loose teeth of this species were found in close proximity to human bones. The teeth were independently dated by electron spin resonance (ESR) in two laboratories. The ages obtained for the teeth were 29 ± 3 ka (thousands of years) and 24 ± 1 ka. The concretion layer capping this stratum was dated by optically stimulated luminescence (OSL) of the quartz grains to 21 ± 3 ka. As these values were derived independently in three different laboratories, using different methods and equipment, these results are compelling evidence of early habitation in this area.

    The study of landslide susceptibility by multivariate statistical methods is based on finding a quantitative relationship between controlling factors and landslide occurrence. Such studies have become popular in the last few decades thanks to the development of geographic information systems (GIS) software and the related improved data management. In this work we applied a statistical approach to an area of high landslide susceptibility mainly due to its tropical climate and geological-geomorphological setting. The study area is located in the south-east region of Brazil that has frequently been affected by flood and landslide hazard, especially because of heavy rainfall events during the summer season. In this work we studied a disastrous event that occurred on January 11th and 12th of 2011, which involved Região Serrana (the mountainous region of Rio de Janeiro State) and caused more than 5000 landslides and at least 904 deaths. In order to produce susceptibility maps, we focused our attention on an area of 93,6 km2 that includes Nova Friburgo city. We utilized two different multivariate statistic methods: Logistic Regression (LR), already widely used in applied geosciences, and Random Forest (RF), which has only recently been applied to landslide susceptibility analysis. With reference to each mapping unit, the first method (LR) results in a probability of landslide occurrence, while the second one (RF) gives a prediction in terms of % of area susceptible to slope failure. With this aim in mind, a landslide inventory map (related to the studied event) has been drawn up through analyses of high-resolution GeoEye satellite images, in a GIS environment. Data layers of 11 causative factors have been created and processed in order to be used as continuous numerical or discrete categorical variables in statistical analysis. In particular, the logistic regression method has frequent difficulties in managing numerical continuous and discrete categorical variables together; therefore in our work we tried different methods to process categorical variables , until we obtained a statistically significant model. The outcomes of the two statistical methods (RF and LR) have been tested with a spatial validation and gave us two susceptibility maps. The significance of the models is quantified in terms of Area Under ROC Curve (AUC resulted in 0.81 for RF model and in 0.72 for LR model). In the first instance, a graphical comparison of the two methods shows a good correspondence between them. Further, we integrated results in a unique susceptibility map which maintains both information of probability of occurrence and % of area of landslide detachment, resulting from LR and RF respectively. In fact, in view of a landslide susceptibility classification of the study area, the former is less accurate but gives easily classifiable results, while the latter is more accurate but the results can be only subjectively classified. The obtained "integrated" susceptibility map preserves information about the probability that a given % of area could fail for each mapping unit.

  10. Regional scale analysis of landform configuration with base-level (isobase) maps

    NASA Astrophysics Data System (ADS)

    Grohmann, C. H.; Riccomini, C.; Chamani, M. A. C.

    2011-05-01

    Base-level maps (or "isobase maps", as originally defined by Filosofov, 1960), express a relationship between valley order and topography. The base-level map can be seen as a "simplified" version of the original topographic surface, from which the "noise" of the low-order stream erosion was removed. This method is able to identify areas with possible tectonic influence even within lithologically uniform domains. Base-level maps have been recently applied in semi-detail scale (e.g., 1:50 000 or larger) morphotectonic analysis. In this paper, we present an evaluation of the method's applicability in regional-scale analysis (e.g., 1:250 000 or smaller). A test area was selected in northern Brazil, at the lower course of the Araguaia and Tocantins rivers. The drainage network extracted from SRTM30_PLUS DEMs with spatial resolution of approximately 900 m was visually compared with available topographic maps and considered to be compatible with a 1:1,000 000 scale. Regarding the interpretation of regional-scale morphostructures, the map constructed with 2nd and 3rd-order valleys was considered to present the best results. Some of the interpreted base-level anomalies correspond to important shear zones and geological contacts present in the 1:5 000 000 Geological Map of South America. Others have no correspondence with mapped Precambrian structures and are considered to represent younger, probably neotectonic, features. A strong E-W orientation of the base-level lines over the inflexion of the Araguaia and Tocantins rivers, suggest a major drainage capture. A N-S topographic swath profile over the Tocantins and Araguaia rivers reveals a topographic pattern which, allied with seismic data showing a roughly N-S direction of extension in the area, lead us to interpret this lineament as an E-W, southward-dipping normal fault. There is also a good visual correspondence between the base-level lineaments and geophysical anomalies. A NW-SE lineament in the southeast of the study area partially corresponds to the northern border of the Mosquito lava field, of Jurassic age, and a NW-SE lineament traced in the northeastern sector of the study area can be interpreted as the Picos-Santa Inês lineament, identifiable in geophysical maps but with little expression in hypsometric or topographic maps.

    Abstract The mygalomorph neotropical genus Fufius Simon, 1888 comprises ten species, distributed from Guatemala in Central America to southeastern Brazil, in South America. Most of the species were described from northern South America, in the Amazonian region. Only F. funebris Vellard, 1924 and F. lucasae Guadanucci & Indicatti, 2004 are known from regions more to the south of the continent. Herein we describe three new Brazilian species, Fufius minusculus sp. n. and F. jalapensis sp. n. from the state of Tocantins, and F. candango sp. n. from Distrito Federal. The female of F. lucasae is described for first time and the male and female of F. funebris are redescribed based on specimens collected at the type locality. PMID:24294093

    We here investigated the kin structure and pattern of dispersal in the black-and-gold howler monkey (Alouatta caraya, Platyrrhini, Atelidae) based on genotype differences at nine microsatellite loci of 48 individuals from eight social groups along the riparian forest of the Tocantins River, Brazil. The genetic diversity (HE = 0.647) was similar to or higher than previously reported values in other Alouatta species. Given that no spatial kinship structure was detected, we found no evidence that dispersal was constrained by distance within the spatial scale analyzed (<25 km). Although no evidence was found for sex-biased dispersal, our results strongly suggest that extra-group copulations are common in A. caraya, and that both males and females disperse from their natal group.

    The construction of the Tucurui Hydroelectric Plant on the Tocantins River basin in Brazil requires flood forecasting to ensure the safety of the cofferdam. The latter has been initially designed for a flood with a return frequency of one in 25 years. Lack of adequate forecasting facilities during the earlier stages of construction has resulted in significant damages and construction delays. Statistical forecasting models were developed by Projeto de Hidrologia y Climatologie da Amazonia (PHCA) for the purpose of preventing further damage at the site. The application of these models during the 1980 flood season, when the highest flood on record occurred at the Tucurui site, proved of great assistance in preventing the flooding of the cofferdam. In conjunction with the development of these models a number of data collection platforms using data transmission through the GOES system were installed to provide the data required for forecasting.

    During fieldwork carried out in January 2009 at Aurora do Tocantins (Tocantins State, northern Brazil), we recovered a fragmentary right maxilla (UNIRIO-PM 1006) of Catagonus stenocephalus from a sedimentary deposit of presumed late Pleistocene age in a karstic cave. This paper aims to: (1) provide the first record of C. stenocephalus in the northern region of Brazil (and consequently, also the northernmost one); (2) update the geographic distribution of C. stenocephalus; (3) present a date for the specimen; and (4) discuss the palaeoenvironmental and palaeobiogeographical implications of the finding. The species C. stenocephalus (Lund) is known from the Bonaerian (middle Pleistocene) and Lujanian (late Pleistocene to earliest Holocene) ages in Argentina, Uruguay, Brazil and Bolivia. The new record presented here extends the geographical distribution of C. stenocephalus more than 1000 km north from the former northernmost record (caves of Lagoa Santa region). Peccaries of the genus Catagonus have several morphological features associated with cursorial habits in relatively open and dry environments. The new distributional range of C. stenocephalus is coincident with the Chacoan subregion, characterized by dry climates and open areas. As the studied material comes from the top of the carbonate layer, this may suggest that the deposition of the C. stenocephalus remains described here is synchronous with the onset of a wetter climate phase. This argument is also in accordance with the datation results, around 20 ky BP, just after the last glacial maximum. This increasingly wet climate, which may also be related to the climatic changes that occurred during the late Pleistocene/early Holocene, could be a factor in the extinction of C. stenocephalus in South America.

    A Bayesian approach is adopted to analyze the sequence of seismic events and their magnitudes near Jo\\~ao C\\^amara which occurred mainly from 1983 to 1998 along the Samambaia fault. In this work, we choose a Bayesian model for the process of occurrence times conditional on the observed magnitude values following the same procedure suggested by Stavrakakis and Tselentis (1987). The model parameters are determined on the basis of historical and physical information. We generate posterior samples from the joint posterior distribution of the model parameters by using a variant of the Metropolis-Hastings algorithm. We use the results in a variety of ways, including the construction of pointwise posterior confidence bands for the conditional intensity of the point process as a function of time, as well as, a posterior distribuition as a function of the mean of occurrence per unit time.

  7. Influence of El Nino and ITCZ on Brazilian River Streamflows

    Lopes, A.; Dracup, J. A.

    2010-12-01

    This study analyzes effects of climatic phenomena El Nino and ITCZ latitudinal movements on streamflow patterns in major Brazilian river basins: Amazon (north), Araguaia-Tocantins (central-north), Parana (central-south) and Sao Francisco (central-northeast). Multiple correlation between annual streamflows and the NINO 3.4 and North Tropical Atlantic SST indexes (NTA) were analyzed for each river basin using different annual periods in order to account for the delay in streamflow response. The data consists of unimpaired river discharge time series at key points (from the Brazilian National Water Agency (ANA)); normalized yearly averaged NINO3.4 index characterizing El Nino (from NOAA); and NTA index (from NOAA), as a surrogate of the latitudinal movement of the ITCZ, since it is correlated to the Atlantic SST gradient. As a result, each river basin showed a different response. At the Amazon river basin, almost all dry years occurred when NINO3.4 was above average (El Nino years). Moreover, in almost every year when NINO3.4 was below average (La Nina) the streamflows were above average. Thus, it seems that La Nina have strong effects in floods in Amazon river. Moreover, El Nino events seem to be a necessary, but not sufficient condition for low streamflows at Amazon river. A weaker relationship was found for Xingu river basin, since it is probably affected by cold fronts from the south. As the location of river basins changes towards the south, the effect of El Nino events gets weaker as for Araguaia-Tocantins and Sao Francisco river basins. At the Parana river basin, the relationship is reversed. Almost all extreme wet years occurred during El Nino years. The correlation between streamflows and the NTA indexes were very weak for all river basins except for the Amazon. When the NTA anomaly is negative, wet years occurs, since the ITCZ moves southwards and stays longer at that position, increasing rainfall over the Amazon and Northeast of Brazil. In contrast, almost all dry years occurred when the NTA index was positive. Annual streamflows were regressed on climatic indexes NINO 3.4 and NTA. At 95% level of significance, NINO3.4 and NTA indexes are significant variables in predicting streamflows at the Amazon (p=0.01% for NINO3.4 and p=0.30% for NTA) and at the Parana river basins (p=0.23% for NINO3.4 and p=1.11% for NTA). The values of R2 were significant high, 0.59 for Amazon and 0.26 for Parana, compared to very low values for Xingu (0.10), Araguaia-Tocantins (0.06) and Sao Francisco (0.04) river basins. The low correlation at central basins can be explained from the regression coefficients values. The coefficients for NTA index are all negative (except for Xingu river), indicating that negative NTA implies in greater streamflow and vice-versa. However, coefficients for NINO3.4 are negative at the Amazon and positive at Parana which means that negative anomalies (La Nina years) implies in greater streamflows at Amazon and lower streamflows at Parana and vice-versa. Opposite effects of El Nino/La Nina on north and south river basins seems to be neutralized in the central river basins so the correlation gets weaker: during El Nino (La Nina) events, the reduction (increasing) in rainfall at north is counter balanced by the enhancement (reduction) of rainfall at south associated with cold fronts.

    Biomass burning represents one of the largest sources of particulate matter to the atmosphere, which results in a significant perturbation to the Earth's radiative balance coupled with serious negative impacts on public health. Globally, biomass burning aerosols are thought to exert a small warming effect of 0.03 Wm-2, however the uncertainty is 4 times greater than the central estimate. On regional scales, the impact is substantially greater, particularly in areas such as the Amazon Basin where large, intense and frequent burning occurs on an annual basis for several months (usually from August-October). Furthermore, a growing number of people live within the Amazon region, which means that they are subject to the deleterious effects on their health from exposure to substantial volumes of polluted air. Results are presented here from the South American Biomass Burning Analysis (SAMBBA), which took place during September and October 2012 over Brazil. A suite of instrumentation was flown on-board the UK Facility for Airborne Atmospheric Measurement (FAAM) BAe-146 research aircraft. Measurements from the Aerodyne Aerosol Mass Spectrometer (AMS) and Single Particle Soot Photometer (SP2) form the major part of the analysis presented here. The aircraft sampled several fires in close proximity (approximately 150m above the most intense fires) in different areas of Brazil. This included two extensive areas of burning, which occurred in the states of Rondonia and Tocantins. The Rondonia fire was largely dominated by smouldering combustion of a huge single area of rainforest with a visible plume of smoke extending approximately 80km downwind. The Tocantins example contrasted with this as it was a collection of a large number of smaller fires, with flaming combustion being more prevalent. Furthermore, the burned area was largely made up of agricultural land in a cerrado (savannah-like) region of Brazil. Initial results suggest that the chemical nature of these fires differed markedly, with BC concentrations being an order of magnitude greater in the Tocantins case (up to 50 ?g m-3 of BC) compared with the Rondonia case (up to 5 ?g m-3 of BC). Organic matter (OM) concentrations were similar in both cases, with maximum concentrations peaking between 4-5 mg m-3. Such concentrations are approximately more than 100 times greater than those sampled in the "background" regional haze. This variation of BC to OM ratio has potentially large implications for the radiative balance in the respective regions, as BC represents the major absorbing component of biomass burning aerosol. Further analysis will compare the aerosol mass concentrations with gas phase species, as well as probing the chemical and physical evolution of the aerosol as it advects downwind and is diluted with regional air. In particular, such analyses will focus upon the aging of the organic aerosol component as well as examining how the mixing state of the BC particles evolves. Such properties have important implications for the life cycle and formation of particulate material, which governs its subsequent impacts.

  9. Magnetic expression of the Transbrasiliano Lineament, Brazil

    The Transbrasiliano lineament is a continental-sized discontinuity exposed between the Amazonian craton and the eastern portion of the South American Platform. It is over 3,000 km long, extending from northern Paraguay, across the Tocantins Province and the Phanerozoic Paraná and Parnaíba basins, down to the Ceará Atlantic coast. In the context of West Gondwana, this large continental structure extends to the African continent along the 4o30 lineament. Its NE-SW preferential trend is marked by strong magnetic anomalies at the crustal level and by low velocity zones of S waves within the mantle, suggesting lithosphere thinning. On the surface the Transbrasiliano lineament translates as aligned drainage and ridges in the continental relief, and is comprised of a set of N20-50E Late Neoproterozoic ductile right-lateral shear zones, brittlely reactivated during the Mesozoic. Different interpretations were forwarded along the years, suggesting that the lineament represents a mega-suture active during Gondwana Supercontinent amalgamation, in the Late Neoproterozoic and Early Paleozoic, or seeing the strike-slip ductile faults as the result of shearing related with post-collision stages of the Brasiliano orogeny. Fault reactivation is believed to have controlled graben formation, sediment accumulation and magmatism of the Jaibaras basin in NW Ceará, as well as the establishing of depocentres within the Paraná and Parnaíba basins, influencing also sedimentation at the Atlantic coast. Although a direct link with the lineament has not been established, nearby areas are the site of seismic activity, mainly in NW Ceará and close to the Goiás-Tocantins border in central Brazil. The lineament is covered by aeromagnetic surveys collected over decades. Qualitative interpretation of magnetic and remote sensing data shows that the Transbrasiliano lineament is comprised of a system of ductile shear zones, forming parallel sets of faults penetrating below the large Paraná and Parnaiba intracontinental syneclises with almost continuous traces. Main direction is N45E, connected with splays of E-W and N-S secondary lineaments. Magnetic lineaments developed dominantly along the borders of crustal/lithospheric blocks, determining their limits. Magnetic Euler deconvolution preliminary results indicates depths up to 5 km. The magnetic lineaments continue below the intracratonic Phanerozoic basins, where brittle fault zones characterize several tectonic reactivation events from the Cambrian up to the Cenozoic. These results stress the outstanding role of the Transbrasiliano lineament in the tectonic framework of the Brazilian continental crust/lithosphere and the relevance of its set of faults in the infilling and evolution of large intracontinental Phanerozoic syneclises.

  10. Flexural Stresses are a Major Factor to Enhance Intraplate Seismicity in Central Brazil

    NASA Astrophysics Data System (ADS)

    Assumpcao, M.; Sacek, V.

    2012-12-01

    Explaining intraplate seismic activity has been a challenging task. Several different models have been proposed combining weak crustal zones and mechanisms of stress concentration. Here we propose that stress concentration due to flexural deformation is one of the most important factors to explain seismicity in Central Brazil, especially the SW-NE oriented seismic zone between the Amazon and the São Francisco cratons, called "Goiás-Tocantins Seismic Zone" (GTSZ). This activity has been usually associated with the TransBrasiliano Lineament (TBL), a major Paleozoic transcontinental feature. However, two observations cast doubt on a direct relationship with the Lineament. First, the seismic activity in the Tocantins province is parallel but not coincident with the TBL; secondly, the continental scale TransBrasiliano Lineament shows no seismic activity further to the NE (beneath the Parnaíba basin), while to the SW, the seismic activity follows an E-W and then N-S direction, not coincident with the TBL. On the other hand, the seismic zone coincides exactly with the trend of high isostatic gravity anomalies (above -20 mGal), which were interpreted as due to high-density mantle rocks beneath a belt of thin crust (roughly beneath the Goiás Magmatic Arc and the Central Massif). Upper crustal stresses due to flexural deformation were calculated with finite-element methods assuming a visco-elastic lithosphere overlying a very soft asthenosphere. The lithospheric load due to the shallow, high-density mantle rocks produces compressional stresses up to 100 MPa in the 200 km wide GTSZ. Regional compressive stresses from plate boundary forces combine with the local flexural stresses to reach seismogenic levels in the GTSZ. Away from the central zone of horizontal compression, extensional stresses (related to the peripheral bulge) balance the regional compression, which explains the aseismic areas. Three other seismic clusters (the N-S belt along the Eastern border of the Amazon craton near Carajás, the cluster of seismicity at the northern border of the Parecis Basin (Porto dos Gauchos Seismic Zone), and the active Pantanal Basin overlying the Paraguay foldbelt) are also located in areas of predominantly positive isostatic anomalies. For this reason we propose that similar compressional flexural stresses enhance the regional, plate-wide stresses up to seismogenic levels in other areas and are an important factor to explain the mid-plate seismicity in Brazil.

  11. Biomass burning emissions of reactive gases estimated from satellite data analysis and ecosystem modeling for the Brazilian Amazon region

    NASA Astrophysics Data System (ADS)

    To produce a new daily record of trace gas emissions from biomass burning events for the Brazilian Legal Amazon, we have combined satellite advanced very high resolution radiometer (AVHRR) data on fire counts together for the first time with vegetation greenness imagery as inputs to an ecosystem biomass model at 8 km spatial resolution. This analysis goes beyond previous estimates for reactive gas emissions from Amazon fires, owing to a more detailed geographic distribution estimate of vegetation biomass, coupled with daily fire activity for the region (original 1 km resolution), and inclusion of fire effects in extensive areas of the Legal Amazon (defined as the Brazilian states of Acre, Amapá, Amazonas, Maranhao, Mato Grosso, Pará, Rondônia, Roraima, and Tocantins) covered by open woodland, secondary forests, savanna, and pasture vegetation. Results from our emissions model indicate that annual emissions from Amazon deforestation and biomass burning in the early 1990s total to 102 Tg yr-1 carbon monoxide (CO) and 3.5 Tg yr-1 nitrogen oxides (NOx). Peak daily burning emissions, which occurred in early September 1992, were estimated at slightly more than 3 Tg d-1for CO and 0.1 Tg d-1for NOx flux to the atmosphere. Other burning source fluxes of gases with relatively high emission factors are reported, including methane (CH4), nonmethane hydrocarbons (NMHC), and sulfur dioxide (SO2), in addition to total particulate matter (TPM). We estimate the Brazilian Amazon region to be a source of between one fifth and one third for each of these global emission fluxes to the atmosphere. The regional distribution of burning emissions appears to be highest in the Brazilian states of Maranhao and Tocantins, mainly from burning outside of moist forest areas, and in Pará and Mato Grosso, where we identify important contributions from primary forest cutting and burning. These new daily emission estimates of reactive gases from biomass burning fluxes are designed to be used as detailed spatial and temporal inputs to computer models and data analysis of tropospheric chemistry over the tropical region.

    Freshwater stingrays cause many serious human injuries, but identification of the offending species is uncommon. The present case involved a large freshwater stingray, Potamotrygon motoro (Chondrichthyes: Potamotrygonidae), in the Araguaia River in Tocantins, Brazil. Appropriate first aid was administered within ~15 min, except that an ice pack was applied. Analgesics provided no pain relief, although hot compresses did. Ciprofloxacin therapy commenced after ~18 h and continued seven days. Then antibiotic was suspended; however, after two more days and additional tests, cephalosporin therapy was initiated, and proved successful. Pain worsened despite increasingly powerful analgesics, until debridement of the wound was performed after one month. The wound finally closed ~70 days after the accident, but the patient continued to have problems wearing shoes even eight months later. Chemistry and pharmacology of Potamotrygon venom and mucus, and clinical management of freshwater stingray envenomations are reviewed in light of the present case. Bacterial infections of stingray puncture wounds may account for more long-term morbidity than stingray venom. Simultaneous prophylactic use of multiple antibiotics is recommended for all but the most superficial stingray wounds. Distinguishing relative contributions of venom, mucus, and bacteria will require careful genomic and transcriptomic investigations of stingray tissues and contaminating bacteria. PMID:26094699

    Three strains of a novel yeast species were isolated from water tanks (phytotelmata) of a bromeliad species collected in the state of Tocantins, Brazil. Analysis of sequences for the region spanning the SSU rRNA gene, the internal transcribed spacer, the 5.8S rRNA gene and the D1/D2 domains of the LSU rRNA gene and RNA polymerase II gene showed that these novel yeasts belong to a species that is distinct from all recognized ascomycetous yeast species. Based on the results of gene sequence analyses, a novel species representing a new genus in the Saccharomycetaceae is proposed. The novel species is assigned to the genus Hagleromyces gen. nov. The three isolates of the novel yeast species failed to form sexual spores alone or in mixtures. The name Hagleromyces aurorensis sp. nov. is proposed to accommodate these isolates. The type strain of H. aurorensis sp. nov. is UFMG-CM-Y311(T) (?=?CBS 13264(T)). PMID:24879649

    Although five genera of procyonids are currently present in South America, only two of the extant genera, Procyon and Nasua are represented in the South American fossil record. A recent discovery of a procyonid lower second molar in Late Pleistocene deposits of Aurora do Tocantins, northern Brazil, offers potential to further our understanding of the stratigraphic and temporal range of South American fossil procyonids. We use geometric morphometric analysis of two-dimensional landmarks and semilandmarks to explore morphological variation in the lower second molars of extant Procyon lotor and Procyon cancrivorus and multivariate methods to support the identification of the Pleistocene specimen as P. cancrivorus. This material represents the second fossil record of P. cancrivorus in South America Procyonids entered South America in two phases: the first comprising by Cyonasua and Chapadmalania during the Late Miocene, and the other recent genera, beginning in the Late Pleistocene. These Late Miocene procyonids were more carnivorous than Late Pleistocene-Recent omnivorous taxa and possible went extinct due to competition with other placental carnivorans that entered South America and diversified during the latest Pliocene-Early Pleistocene.

    The Parnaiba Sedimentary Basin is of the Paleozoic age and is located in Northeast Brazil, covering the states of Piauí, Maranhão and Tocantins and a small part of Ceará and Pará. In this work we applied several chemical analytical techniques to characterize trunk fossils found in the Parnaíba Sedimentary Basin, collected from four different sites, and discuss their fossilization process. We performed a study of the trunk fossils through X-ray diffraction, energy dispersive spectroscopy, infrared and Raman spectroscopy. The analysis allow us to identify the different compositions which are present in the trunk fossils: kaolinite (Al2Si2O5(OH)4), hematite (Fe2O3) and quartz (SiO2). Based in these results we were able to identify that the main fossilization mechanism of the trunk fossil was silicification. Furthermore, through Raman spectroscopy, we have observed the presence of carbonaceous materials in the Permian fossils, as evidenced by the D and G Raman bands. The relative intensities and bandwidths of the D and G bands indicated that the carbon has a low crystallinity. Thus, most of trunk fossils analyzed were permineralized and not petrified, because there is the presence of carbon that characterizes the partial decomposition of the organic matter in some trunks.

    We have assembled datasets to strengthen the LargeScale Biosphere Atmosphere Experiment in Amazonia (LBA). These datasets can now be accessed through the Woods Hole Research Center homepage (www.whrc.org), and will soon be linked to the Pre-LBA homepages of the Brazilian Space Research Institute's Center for Weather and Climate Prediction (Instituto de Pesquisas Espaciais, Centro de Previsao de Tempo e Estudos Climaticos, INPE/CPTEC) and through the Oak Ridge National Laboratory, Distributed Active Archive Center (ORNL/DMC). Some of the datasets that we are making available involved new field research and/or the digitization of data available in Brazilian government agencies. For example, during the grant period we conducted interviews at 1,100 sawmills across Amazonia to determine their production of sawn timber, and their harvest intensities. These data provide the basis for the first quantitative assessment of the area of forest affected each year by selective logging (Nepstad et al, submitted to Nature). We digitized the locations of all of the rural households in the State of Para that have been mapped by the Brazilian malaria combat agency (SUCAM). We also mapped and digitized areas of deforestation in the state of Tocantins, which is comprised largely of savanna (cerrado), an ecosystem that has been routinely excluded from deforestation mapping exercises.

    Thirty-four rabies virus (RV) isolates from foxes (8), insectivore bats (9), cattle (14), sheep (1), a goat (1) and a donkey (1) from Paraiba state, northeastern Brazil, were genetically characterized. Sequences of 890 nts of nucleoprotein (N) genes of these isolates were analyzed and compared with those of other Brazilian isolates characterized earlier. Phylogenetic analysis revealed three genetical lineages of RV co-existing in this region. Each lineage was found to be associated with particular host species and to circulate independently of each other. The first lineage was found in foxes (Dusicyon sp.) and could be discriminated from domestic carnivore isolates from Sao Paulo, Goias and Minas Gerais in the southern and central Brazil. The second lineage was associated with insectivorous bats (Molossus spp.) and differed from vampire bat-associated RV isolates. The third lineage was found in livestock and clustered with vampire bat-associated RV isolates from Sao Paulo, Tocantins, Goias and Matto Grosso. These results indicate that RV of these genetic lineages are cocirculating in the Paraiba state and that livestock in this region are infected with vampire bat-associated RV, suggesting that the vampire bat is the main reservoir of livestock rabies in this region.

    The Parnaíba Basin is a large Paleozoic syneclise in northeastern Brazil underlain by Precambrian crystalline basement, which comprises a complex lithostructural and tectonic framework formed during the Neoproterozoic-Eopaleozoic Brasiliano-Pan African orogenic collage. A sag basin up to 3.5 km thick and 1000 km long formed after the collage. The lithologic composition, structure, and role in the basin evolution of the underlying basement are the focus of this study. Airborne gravity and magnetic data were modeled to reveal the general crustal structure underneath the Parnaíba Basin. Results indicate that gravity and magnetic signatures delineate the main boundaries and structural trends of three cratonic areas and surrounding Neoproterozoic fold belts in the basement. Triangular-shaped basement inliers are geophysically defined in the central region of this continental-scale Neoproterozoic convergence zone. A 3-D gravity inversion constrained by seismological data reveals that basement inliers exhibit a 36-40.5 km deep crustal root, with borders defined by a high-density and thinner crust. Forward modeling of gravity and magnetic data indicates that lateral boundaries between crustal units are limited by Brasiliano shear zones, representing lithospheric sutures of the Amazonian and São Francisco Cratons, Tocantins Province and Parnaíba Block. In addition, coincident residual gravity, residual magnetic, and pseudo-gravity lows indicate two complex systems of Eopaleozoic rifts related to the initial phase of the sag deposition, which follow basement trends in several directions.

    True river dolphins are some of the rarest and most endangered of all vertebrates. They comprise relict evolutionary lineages of high taxonomic distinctness and conservation value, but are afforded little protection. We report the discovery of a new species of a river dolphin from the Araguaia River basin of Brazil, the first such discovery in nearly 100 years. The species is diagnosable by a series of molecular and morphological characters and diverged from its Amazonian sister taxon 2.08 million years ago. The estimated time of divergence corresponds to the separation of the Araguaia-Tocantins basin from the Amazon basin. This discovery highlights the immensity of the deficit in our knowledge of Neotropical biodiversity, as well as vulnerability of biodiversity to anthropogenic actions in an increasingly threatened landscape. We anticipate that this study will provide an impetus for the taxonomic and conservation reanalysis of other taxa shared between the Araguaia and Amazon aquatic ecosystems, as well as stimulate historical biogeographical analyses of the two basins.

    A comparison between daily in-situ water level time series measured at ground-based hydrometric stations (HS - 1,899 stations located in twelve Brazilian basins) of the Agência Nacional de Águas (ANA) with vertically-integrated water height anomaly deduced from the Gravity Recovery and Climate Experiment (GRACE) geoid is carried out in Brazil. The equivalent water height (EWH) of 10-day intervals of GRACE models were computed by GRGS/CNES. It is a 6-year analysis (July-2002 to May-2008). The coefficient of determination is computed between the ANA water level and GRACE EWH. Values higher than 0.6 were detected in the following basins: Amazon, north of Paraguay, Tocantins-Araguaia, Western North-East Atlantic and north of the Parnaíba. In the Uruguay (Pampas region) and the west of São Francisco basins, the coefficient of determination is around 0.5 and 0.6. These results were adjusted with a linear transfer function and two second degree polynomials (flood and ebb period) between GRACE EWH and ANA water level. The behavior of these two polynomials is related to the phase difference of the two time series and yielded four different types of responses. This paper shows seven ANA stations that represent these responses and relates them with their hydro-geological domain.

    Purpose To describe an extremely uncommon outbreak of eye lesions in a specific area of the Brazilian Amazonia. Methods Prospective noncomparative case series. Fifty-nine patients who developed eye lesions after swimming in the Araguaia river of Tocantins state in Brazil were examined. A team of ophthalmologists equipped with a slit-lamp, gonioscopic lenses, and indirect ophthalmoscopy performed full eye examination. Analysis of the flora and fauna of the river water was undertaken by a group of experts. Results and Conclusions Eighty-three eyes were affected. The most common lesions were corneal opacities seen in 34 eyes and conjunctival nodules diagnosed in 12 eyes. Severe visual acuity loss was detected in seven children with unilateral anterior chamber lesions. Spicules of the sponge species Drulia uruguayensis and Drulia ctenosclera were found inside three blind eyes that have been enucleated for diagnostic purposes. All eye lesions could be attributed to an outbreak of foreign bodies from fresh water sponges. Organic enrichment of the water resulting from the absence of sanitation probably was the key factor, which initiated a cycle of ecological imbalance that provoked human disease. PMID:23306731

  12. Precambrian Cratons and Fold-Belts in Brazil: Overview

    NASA Astrophysics Data System (ADS)

    Fuck, R.

    The main Precambrian terrains recognized in Brazil comprise the Amazonian, São Francisco and Rio de la Plata cratons, surrounded by Neoproterozoic Brasiliano fold belts, making up the Borborema, Mantiqueira and Tocantins provinces. The Amazonian craton comprises an Archean core, surrounded by Paleoproterozoic terrains (Maroni-Itacaiunas, Ventuari-Tapajós, Rio Negro-Juruena), which southwestwards give way to the Mesoproterozoic Rondoniano-San Ignacio and Sunsas belts, the latter thought to be related to the Grenville belt of North America. The São Francisco craton comprises several Archean blocks (Gavião, Serrinha, Jequié) amalgamated by the Paleoproterozoic high-grade Itabuna-Salvador-Curaçá orogen. The Rio de la Plata craton, largely covered by Phanerozoic strata, is made of Paleoproterozoic basement gneiss and several Paleoproterozoic greenstone belts. Other cratonic blocks are hidden below large Phanerozoic basins, like the Paranapanema and Parnaíba blocks below the Paraná and Parnaíba basins, respectively. Several smaller Archean/Paleoproterozoic blocks appear within the Brasiliano provinces: some were strongly reworked during the Neoproterozoic orogenic events (São José do Campestre, Pernambuco-Alagoas, Goiás, Guanhães, Juiz de Fora, Curitiba), others were only marginally affected (São Luiz, Rio Apa, Luís Alves). The Brasiliano provinces are the result of Neoproterozoic to early Paleozoic orogenic events within the framework of West Gondwana amalgamation. The Mantiqueira Province extends from eastern Brazil to southern Uruguay and includes the Araçuaí, Ribeira and Dom Feliciano fold belts, bordering the São Francisco, Paranapanema and Rio de la Plata cratons and surrounding the Luís Alves craton. The Tocantins province in central Brazil includes the Araguaia, Paraguay and Brasília fold belts, the former bordering the Amazonian craton, the second bordering both the southern Amazonian craton and the Rio Apa block, and the last established on the western border of the São Francisco craton and on the northeastern margin of the Paranapanema block. Deep seismic refraction and other geophysical and geological studies were able to discriminate several crust compartments within the Brasília belt, like the juvenile Goiás magmatic arc, the Archean/Paleoproterozoic Goiás massif, and the external belt zone, as distinguished from the São Francisco craton. The Borborema Province in northeast Brazil is a complex array of Neoproterozoic fold belts (Médio Coreaú, Seridó, Sergipana, Riacho do Pontal, Rio Preto) between the São Luiz and São Francisco cratons, partially covering different crustal blocks (NW Ceará, Ceará Central, Rio Grande do Norte, Pernambuco-Alagoas) separated by large crustal-scale, strike-slip lineaments (Transbrasiliano, Senador Pompeu, Orós, Porta Alegre, Patos, Pernambuco, etc.). Basement of the crustal blocks is mainly Paleoproterozoic in age, but may include Archean cores (São José do Campestre, Grangeiro, Troia). South of the Patos lineament, Mesoproterozoic gneiss, granite and supracrustal belts are recorded in the Transversal domain, in the Pernambuco-Alagoas massif and in the Sergipano and Riacho do Pontal fold belts. Geophysical studies (MT sounding, gravity, seismology, deep seismic refraction, etc.) are underway in order to understand crustal structure and evolution of the province.

  13. Influence of environmental variables on diffusive greenhouse gas fluxes at hydroelectric reservoirs in Brazil.

    For almost two decades, studies have been under way in Brazil, showing how hydroelectric reservoirs produce biogenic gases, mainly methane (CH4) and carbon dioxide (CO2), through the organic decomposition of flooded biomass. This somewhat complex phenomenon is due to a set of variables with differing levels of interdependence that directly or indirectly affect greenhouse gas (GHG) emissions. The purpose of this paper is to determine, through a statistical data analysis, the relation between CO2, CH4 diffusive fluxes and environmental variables at the Furnas, Itumbiara and Serra da Mesa hydroelectric reservoirs, located in the Cerrado biome on Brazil's high central plateau. The choice of this region was prompted by its importance in the national context, covering an area of some two million square kilometers, encompassing two major river basins (Paraná and Tocantins-Araguaia), with the largest installed power generation capacity in Brazil, together accounting for around 23% of Brazilian territory. This study shows that CH4 presented a moderate negative correlation between CO2 and depth. Additionally, a moderate positive correlation was noted for pH, water temperature and wind. The CO2 presented a moderate negative correlation for pH, wind speed, water temperature and air temperature. Additionally, a moderate positive correlation was noted for CO2 and water temperature. The complexity of the emission phenomenon is unlikely to occur through a simultaneous understanding of all the factors, due to difficulties in accessing and analyzing all the variables that have real, direct effects on GHG production and emission.

    We genotyped 15 microsatellite loci in order to evaluate the effects of habitat fragmentation, caused by flooding of the Tucuruí reservoir, on the genetic structure of Alouatta belzebul in eastern Amazonia. The analysis included two populations sampled in 1984, representing both margins of the Tocantins river, and three populations sampled 18 years later. Minimal differences in the diversity levels between present-day (Ho = 0.62-0.69 and A(R) = 6.07-7.21) and pre-flooding (Ho = 0.60-0.62 and A (R) = 6.27-6.77) populations indicated there was no significant loss of genetic variability, possibly because of successful management strategies applied during the flooding. The changes observed were limited to shifts in the composition of alleles, which presumably reflect the admixture of subpopulations during flooding. Given this, there were significant differences in the Rst values (p = 0.05) in all but one between-site comparison. Both present-day and original populations showed a deficit of heterozygotes, which suggests that this may be typical of the species, at least at a local level, perhaps because of specific ecological characteristics. The relatively large number of private alleles recorded in all populations may be a consequence of the Wahlund effect resulting from population admixture or a process of expansion rather than the loss of rare alleles through genetic drift. Additionally, the levels of genetic variability observed in this study were higher than those reported for other species of Neotropical primates, suggesting good fitness levels in these A. belzebul populations. Regular genetic monitoring of remnant populations, especially on islands, should nevertheless be an integral component of long-term management strategies. PMID:21637590

    We present a crustal thickness map of Brazil and adjacent areas based on a compilation of data published in the literature as well as new measurements. We used crustal thicknesses mainly derived from seismic datasets such as deep seismic refraction experiments, receiver function analyses, and surface-wave dispersion velocities. Crustal thicknesses derived from modelling gravity anomalies commonly depend on assumptions, such as constant density contrast across the Moho interface, which are not always easily verifiable and were considered only along the continental shelf to fill large gaps in the seismic data. Our compilation shows that the crust in the stable continental area onshore has an average thickness of 39 ± 5 km (1-? deviation) and that no clear difference can be observed between low altitude, intracratonic sedimentary basins, NeoProterozoic foldbelts (except for the Borborema Province), and cratonic areas. The thinnest crust is found in the Borborema Province of NE Brazil (30-35 km) and along a narrow belt within Tocantins Province (˜35 km), roughly parallel to the Eastern border of the Amazon craton, while the thickest crust is found in the Amazon and São Francisco cratons (41 ± 4 km), and the Paraná Basin (42 ± 4 km). Both the Ponta Grossa and the Rio Grande Arches are areas of thinned crust, and the western border of the Brazilian platform, near the sub-Andean region, seems to be characterized by a crustal thickness of less than 40 km. Although sparse in data coverage, we expect the resulting crustal thickness map to be useful for future studies of isostasy, dynamic topography, and crustal evolution of the country.

    The genus Xiphorhynchus is a species rich avian group widely distributed in Neotropical forests of Central and South America. Although recent molecular studies have improved our understanding of the spatial patterns of genetic diversity in some species of this genus, most are still poorly known, including their taxonomy. Here, we address the historical diversification and phylogenetic relationships of the X. guttatus/susurrans complex, using data from two mitochondrial (cyt b and ND2) and one nuclear (?-fibint7) genes. Phylogenetic relationships were inferred with both gene trees and a Bayesian-based species tree under a coalescent framework (?BEAST). With exception of the nuclear ?-fibint7 gene that produced an unresolved tree, both mtDNA and the species tree showed a similar topology and were congruent in recovering five main clades with high statistical support. These clades, however, are not fully concordant with traditional delimitation of some X. guttatus subspecies, since X. g. polystictus, X. g. guttatus, and X. g. connectens are not supported as distinct clades. Interestingly, these three taxa are more closely related to the mostly trans-Andean X. susurrans than the other southern and western Amazonian subspecies of X. guttatus, which constitutes a paraphyletic species. Timing estimates based on the species tree indicated that diversification in X. guttatus occurred between the end of the Pliocene and early Pleistocene, likely associated with the formation of the modern Amazon River and its main southern tributaries (Xingu, Tocantins, and Madeira), in addition to climate-induced changes in the distribution of rainforest biomes. Our study supports with an enlarged dataset a previous proposal for recognizing at least three species level taxa in the X. guttatus/susurrans complex: X. susurrans, X. guttatus, and X. guttatoides.

    Evapotranspiration (ET) is difficult to measure at the scales of climate models and climate variability. While satellite retrieval algorithms do exist, their accuracy is limited by the sparseness of in situ observations available for calibration and validation, which themselves may be unrepresentative of 500m and larger scale satellite footprints and grid pixels. Here, we use a combination of satellite and ground-based observations to close the water budgets of seven continental scale river basins (Mackenzie, Fraser, Nelson, Mississippi, Tocantins, Danube, and Ubangi), estimating mean ET as a residual. For any river basin, ET must equal total precipitation minus net runoff minus the change in total terrestrial water storage (TWS), in order for mass to be conserved. We make use of precipitation from two global observation-based products, archived runoff data, and TWS changes from the Gravity Recovery and Climate Experiment satellite mission. We demonstrate that while uncertainty in the water budget-based estimates of monthly ET is often too large for those estimates to be useful, the uncertainty in the mean annual cycle is small enough that it is practical for evaluating other ET products. Here, we evaluate five land surface model simulations, two operational atmospheric analyses, and a recent global reanalysis product based on our results. An important outcome is that the water budget-based ET time series in two tropical river basins, one in Brazil and the other in central Africa, exhibit a weak annual cycle, which may help to resolve debate about the strength of the annual cycle of ET in such regions and how ET is constrained throughout the year. The methods described will be useful for water and energy budget studies, weather and climate model assessments, and satellite-based ET retrieval optimization.

    Studies on the seasonal variation of agricultural pest species are important for the establishment of integrated pest control programs. The seasonality of pest attacks on crops is affected by biotic and abiotic factors, for example, climate and natural enemies. Besides that, characteristics of the host plant, crop management, location and the pests' bioecology also affect this seasonality. The mites Polyphagotarsonemus latus (Prostigmata: Tarsonemidae) and Tetranychus bastosi (Prostigmata: Tetranychidae) are the most important pests in the cultivation of physic nut, Jatropha curcas (Euphorbiaceae). All parts of J. curcas can be used for a wide range of purposes. In addition many researchers have studied its potential for use as neat oil, as transesterified oil (biodiesel), or as a blend with diesel. However studies about physic nut pests have been little known. The objective of this study was to assess the seasonal variation of P. latus and T. bastosi in physic nut. This study was conducted at three sites in the state of Tocantins, Brazil. We monitored climatic elements and the densities of the two mite species and of their natural enemies for a period of 2 years. Attack by P. latus occurred during rainy seasons, when the photoperiod was short and the physic nut had new leaves. In contrast, attack by T. bastosi occurred during warmer seasons with longer photoperiods and stronger winds. Populations of both mites and their natural enemies were greater in sites with greater plant diversity adjacent to the plantations. The predators found in association with P. latus and T. bastosi were Euseius concordis (Acari: Phytoseiidae), spiders, Stethorus sp. (Coleoptera: Coccinellidae) and Chrysoperla sp. (Neuroptera: Chrysopidae). PMID:25910991

    Results are reported from an airborne campaign to investigate the impacts of burning biomass upon the loading of lower-tropospheric aerosols and its composition over the Brazilian tropics. The flights, conducted as part of the NASA/Transport and Atmospheric Chemistry Near the Equator-Atlantic (TRACE A) mission, started on September 1, 1992, when the dry (fire) season still prevailed in the central part of Brazil, and ended on September 29. Of the total number of burnings detected in Brazil by the advanced very high resolution radiometer (AVHRR)/NOAA satellite sensor, 74% were concentrated in the states of Amazonas, Maranhão, Mato Grosso, Pará, Roraima, and Tocantins during this period. Aerosol particles were sampled from a twin-engine aircraft in transit and vertical profile flights were made up to 4,000 m altitude. Black carbon measurements made in real time and in areas of burning biomass peaked at ˜2,500 m above the ground, increasing to ˜12,000 ng/m3. In other areas these values were lower by 1 order of magnitude. A condensation nuclei counter measuring small particles (>0.014 ?m) produced values ranging from 2,000 to 16,000/cm3 for areas with low and high burning biomass, respectively. Deposition filters in a two-stage cascade impactor, and Nuclepore filters collected aerosols for analysis of 13 elements through particle-induced X ray emissions (PIXE). Primary elements associated with soil dust (Al, Si, Mn, Fe, Ni) prevailed in the aerosol coarse mode (>1 ?m) while the fine mode aerosols were enriched in S, K, Br, and Rb, which are tracers normally associated with burning of biomass. The good correlation between fire spot counts, obtained via AVHRR aboard NOAA satellites, and black carbon, counts of small particles and total aerosol mass, suggests the determining of local concentrations of fire-derived aerosol fire emissions by satellite to be a new and useful approach.

  1. Orosirian (ca. 1.96 Ga) mafic crust of the northwestern São Francisco Craton margin: Petrography, geochemistry and geochronology of amphibolites from the Rio Preto fold belt basement, NE Brazil

    The bulk of the Atlantic shield basement in the eastern South American platform is made of Rhyacian calc-alkaline magmatic rocks (?2.2-2.15 Ga) affected by granulite-facies metamorphism at around 2.06 Ga, as part of a Paleoproterozoic orogenic system which joined Archean crustal fragments together. Orosirian (2050-1800 Ma) rocks, on the other hand, are scarce in all four major provinces of eastern South America (the Borborema, São Francisco, Tocantins and Mantiqueira provinces). Recently, however, sparse occurrences of Orosirian-aged rocks have been described, particularly in the northern São Francisco Craton margin and adjoining fold belts that compose the Borborema Province further north. In this paper, we present new geochemical, geochronological and isotopic data of amphibolites which compose the basement of the Rio Preto fold belt, in the northwestern São Francisco Craton margin. Geochemical data suggest tholeiitic gabbro protoliths intruded in a subduction-related setting, as suggested by tectonic discrimination diagrams and differentiation trends. U-Pb analyses of magmatic zircon crystals yielded a 1958.3 ± 16 Ma Concordia age. Slightly negative to positive ?Nd(1.96) = (-0.3 to +1.0) and ?Hf(1.96) from -0.76 to -4.55 suggest variable mixing of a depleted mantle source and older continental crust. We interpret the amphibolite body as a remnant of a subduction-related crustal fragment developed in the Orosirian, around 1.96 Ga ago, possibly in a continental back-arc setting. This crustal fragment was further reworked as part of the basement of the Rio Preto fold belt during the Brasiliano Orogeny (?600-550 Ma). The Cristalândia do Piauí Complex gneisses further north might represent fragments of a coeval continental magmatic arc. These rocks could be the first well documented representatives of an Orosirian tectono-magmatic event which has been, up to now, broadly ignored within this portion of West Gondwana, and thus present major implications for the Proterozoic crustal evolution of South America and for Paleoproterozic supercontinent reconstructions in general.

  2. How Much Do We Know about the Storage Changes in the Major River Basins of the World? Analysis of Storage Change from GRACE

    Change in storage is an important component of water cycle that is often ignored in large-scale hydrologic studies due to limited data and difficulty in measurement. For the first time, this study quantifies and inter-compares storage changes in major river basins of the world. Gravity Recovery and Climate Experiment (GRACE) monthly mass deviation in storage (MDS) data over 2003-2013 is used to compute monthly, annual and long-term change in storage (?S) for 51 major river basins of the world (> 200,000 km2). For each river basin, GRACE ?S is analyzed to understand a) temporal variability in ?S b) magnitude of ?S at annual and decadal time scales and c) duration of storage cycle (time taken by a basin in months to return to initial storage condition). This study identified that 11, 33 and 7 out of 51 basins showed high, medium and low month to month variability in storage changes, respectively. Compared to basin precipitation, 48 out of 51 river basins showed storage to be considerable (5 - 35% of basin annual precipitation). Only 3 basins (Irrawaddy, St. Lawrence, and Brahmaputra) showed minimum variability in storage (< 5%). At long-term (decadal) time-scales, all the 51 river basins showed negligible storage changes (< 0.5%). This result emphasizes the fact that change in storage, ?S is substantial at monthly and annual time scales but can be ignored over a decadal time scale. Analysis of storage cycle for each basin revealed that a basin can take anywhere from 5 to 12 months to restore itself. While, 14 out of 51 basins showed biannual storage cycle (? 6 months), six basins (Zambezi, Mekong, Orinoco, Tocantins, and Amazon) showed annual storage cycle of 12 months. Our results indicate that most basins within the tropics show positive correlation with precipitation indicating that precipitation is the main driver of storage. On the other hand, ?S in the basins located in the higher latitudes mostly show negative correlation with precipitation. This study provides new insights into how basin storage changes in the major river basins. Future study would focus on the analysis of ?S over large river basins within the United States. Such analysis and estimates of ?S would help to (i) improve our knowledge of water availability and (ii) meet the goals of the WaterSMART (Sustain and Manage America's Resources for Tomorrow) project.
