Morphological and anatomical observations about Mariliasuchus amarali and Notosuchus terrestris (Mesoeucrocodylia) and their relationships with other South American notosuchians.

The phylogenetic relationship of the notosuchians Mariliasuchus amarali (Campanian; Bauru Group) and Notosuchus terrestris (Santonian; Neuquen Group) is revised. Morpho-anatomical evaluation of Mariliasuchus in the current bibliography indicate close relationship with Notosuchus, while cladistic analysis either related Mariliasuchus to Candidodon itapecuruense (Albian/eo-Cenomanian; Sao Luis-Grajau Basin), as part of the phylotaxon Candidodontidae, or to Comahuesuchus brachybuccalis (Santonian; Neuquen Group). Comparative study of specimens shows similarities on the palate, choanae, dentition, retroarticular process, and other structures from Mariliasuchus and Notosuchus supporting the original classification as a Notosuchidae. Preliminary phylogenetic analysis sets these taxa as sister-groups. Reevaluation of a previously published phylogenetic analysis from other authors provides further support for the Mariliasuchus + Notosuchus clade. The current work indicates that Mariliasuchus is a Notosuchidae, refuting its allocation as a Candidodontidae. The influence of character construction and the definition of Notosuchia are discussed.

Distribuição e conservação de aves migratórias neárticas da ordem Charadriiformes (famílias Charadriidae e Scolopacidae) no Brasil

Apesar dos esforços de pesquisa nos últimos anos, muitos dos aspectos das migrações dos charadrídeos e escolopacídeos no Brasil permanecem desconhecidos. A maioria dos estudos em escala local ou regional revela a necessidade de uma síntese das informações em escala espacial adequada para facilitar a detecção dos grandes padrões de movimento destas espécies no país. Desta forma, esta tese teve como objetivo geral identificar os padrões de distribuição e migrações das espécies de aves das famílias Charadriidae e Scolopacidae que se reproduzem no hemisfério norte e usam o território brasileiro durante as suas migrações, visando desenvolver estratégias para a conservação do grupo. Como objetivos específicos, caracterizar as principais rotas migratórias para estas espécies; identificar as áreas críticas para a conservação utilizando os critérios propostos pela metodologia das AIAs e ACBs; avaliar o estado de conservação atual das áreas críticas para a conservação destas espécies de acordo ao Sistema Nacional de Unidades de Conservação; avaliar se as áreas críticas são parte das áreas prioritárias para a conservação da biodiversidade brasileira; aplicar os critérios da Convenção de Ramsar e da WHSRN para identificar áreas críticas para conservação destas espécies. A base de dados foi estabelecida a partir de levantamento bibliográfico; consultas às coleções científicas de museus brasileiros e estrangeiros; utilização de bases de dados de recuperações de anilhas brasileiras e norte-americanas; dados cedidos por pesquisadores do Brasil, Argentina e Estados Unidos; dados de campo coletados pessoalmente no Pantanal (MS), litoral dos estados do Maranhão e Rio Grande do Sul. Entre os principais resultados, 19 das 24 espécies possuem um conjunto importante de dados, com as demais sendo ocasionais ou com poucas informações. Há uma maior concentração de dados na região costeira do país, com menor cobertura de áreas do interior. A Amazônia Ocidental mostrou-se a menos conhecida nos aspectos abordados, embora seja a via de passagem para algumas das espécies analisadas. O litoral entre a foz do Amazonas e São Luiz, no Maranhão foi a principal área de concentração em termos numéricos. A costa do Rio Grande do Sul foi o segundo local com maior destaque nas análises. Quinze espécies foram registradas em todos os meses do ano, demonstrando que nem todos os indivíduos migram anualmente para o hemisfério norte. Considerando as rotas globais, 8 espécies utilizam a rota do Atlântico e 10 a rota do Mississipi ou do centro da América do Norte. As outras 6 possivelmente utilizam-se das duas rotas. O conhecimento na utilização das 5 rotas propostas por Antas (1983) durante a migração sul-norte indicou que algumas espécies têm registros no interior da Amazônia, período em que possivelmente seus habitats estariam inundados. O padrão de chegada na migração norte-sul no Brasil é entre agosto e outubro, com incremento a partir de setembro. A migração sul-norte ocorre entre meados de março e abril na maioria das espécies. Durante o período não reprodutivo existe um padrão de distribuição ao longo da costa utilizado por 9 espécies, outro continental para 7 espécies no interior e ainda um terceiro, difuso, encontrado em 5 espécies que se distribuem tanto na costa quanto no interior do país. Foram identificadas 260 áreas críticas importantes para as espécies avaliadas. Observou-se que 72% das ACBs identificadas estão fora do SNUC. A sobreposição das ACBs com as Áreas Prioritárias para a Conservação revelou que 46% das primeiras estão sem indicação de importância neste programa. São elegíveis para os critérios da Convenção Ramsar 69 ACBs, enquanto 65 podem ser inseridas no programa da WHSRN. Entre as principais conclusões, o conhecimento de processos biológicos fundamentais à manutenção do ciclo de vida e o curso de suas migrações anuais, de parâmetros relacionados à mudas de penas, ganho de massa corporal, razão sexual e etária das populações migrantes são aspectos ainda insuficientemente detalhados para estas espécies no Brasil, e mesmo na América do Sul, assim como a necessidade de pesquisas que possam gerar estimativas e tendências populacionais, uma vez que em escala global várias destas espécies apresentam declínio populacional.

A concepção de linguagem de professoras alfabetizadoras e sua influência no ensino do ato de ler

This article aims to analyze literacy teachers’ conception of language from the classroom scenes that demonstrate the teaching of the act of reading. For the realization of the objective was carried out research in education like ethnography with two teachers in the 2nd year of elementary school a school of the Municipal located in the city of Sao Luis in Maranhão State, whose main instrument for data generation was participant observation. Also, I was guided by microgenetic analysis in order to focus our gaze to the particular aspect of the situation with attention to the “clues” to extract meaningful data. Authors such as Mikhail Bakhtin (1995, 2003) and scholars in the fi eld of reading, Josette Jolibert (1994), Elie Bajard (2007), among others, were considered core to grasp the meaning assigned by the subjects to teaching the act of reading. The fi ndings reveal that the design language of the teacher infl uences the direction of your practice, determining how to teach reading.

Contextual and individual inequalities in dental pain prevalence among Brazilian adults and elders

This study aimed to assess the prevalence of dental pain among adults and older people living in Brazil's State capitals. Information was gathered from the Telephone Survey Surveillance System for Risk and Protective Factors for Chronic Diseases (VIGITEL) in 2009 (n = 54,367). Dental pain was the outcome. Geographic region, age, gender, race, schooling, private health coverage, smoking, and soft drink consumption were the explanatory variables. Multilevel Poisson regression models were performed. Prevalence of dental pain was 15.2%; Macapa and Sao Luis had prevalence rates greater than 20%; all capitals in the South and Southeast, plus Cuiaba, Campo Grande, Maceio, Recife, and Natal had prevalence rates less than 15%. Factors associated with increased prevalence of dental pain were the North and Northeast regions, female gender, black/brown skin color, lack of private health insurance, smoking, and soft drink consumption. Dental pain is a public health problem that should be monitored by health surveillance systems.

Maternal smoking during pregnancy and primary headache in school-aged children: a cohort study

Background: It is not known whether smoking by mothers during pregnancy is associated with headache in their offspring. Methods: Two prospective cohorts of 869 children aged 10-11 years from Ribeirao Preto (RP) and 805 children aged 7-9 years from Sao Luis (SL) were studied. Data on maternal smoking were collected at birth. Primary headache was defined as a reporting of >= 2 episodes of headache in the past 2 weeks, without any associated organic symptoms. Results: Prevalence of headache was 28.1% in RP and 13.1% in SL as reported by the mothers and 17.5% in RP and 29.4% in SL as reported by the children. Agreement between mothers' report and children's self-report of primary headache in the child was poor. After adjustment, children whose mothers smoked >= 10 cigarettes per day during pregnancy presented higher prevalence of primary headache than their counterparts in both cohorts, as reported by the mother and in RP as reported by the children. Conclusions: Maternal smoking during pregnancy was associated with headache in 7- to 11-year-olds. With one exception, the consistency of the results, despite poor agreement between maternal and children reports of headache, indicates that maternal smoking during pregnancy may contribute to headaches in their children.

Factors Associated with Height Catch-Up and Catch-Down Growth Among Schoolchildren

In developed countries, children with intrauterine growth restriction (IUGR) or born preterm (PT) tend to achieve catch-up growth. There is little information about height catch-up in developing countries and about height catch-down in both developed and developing countries. We studied the effect of IUGR and PT birth on height catch-up and catch-down growth of children from two cohorts of liveborn singletons. Data from 1,463 children was collected at birth and at school age in Ribeirao Preto (RP), a more developed city, and in Sao Luis (SL), a less developed city. A change in z-score between schoolchild height z-score and birth length z-score >= 0.67 was considered catch-up; a change in z-score <=-0.67 indicated catch-down growth. The explanatory variables were: appropriate weight for gestational age/PT birth in four categories: term children without IUGR (normal), IUGR only (term with IUGR), PT only ( preterm without IUGR) and preterm with IUGR; infant's sex; maternal parity, age, schooling and marital status; occupation of family head; family income and neonatal ponderal index (PI). The risk ratio for catch-up and catch-down was estimated by multinomial logistic regression for each city. In RP, preterms without IUGR (RR = 4.13) and thin children (PI<10th percentile, RR = 14.39) had a higher risk of catch-down; catch-up was higher among terms with IUGR (RR = 5.53), preterms with IUGR (RR = 5.36) and children born to primiparous mothers (RR = 1.83). In SL, catch-down was higher among preterms without IUGR (RR = 5.19), girls (RR = 1.52) and children from low-income families ( RR = 2.74); the lowest risk of catch-down (RR = 0.27) and the highest risk of catch-up (RR = 3.77) were observed among terms with IUGR. In both cities, terms with IUGR presented height catch-up growth whereas preterms with IUGR only had height catch-up growth in the more affluent setting. Preterms without IUGR presented height catch-down growth, suggesting that a better socioeconomic situation facilitates height catch-up and prevents height catch-down growth.

Cesarean section and increased body mass index in school children: two cohort studies from distinct socioeconomic background areas in Brazil

Abstract Background Recent studies have raised controversy regarding the association between cesarean section and later obesity in the offspring. The purpose of this study was to assess the association of cesarean section with increased body mass index (BMI) and obesity in school children from two Brazilian cities with distinct socioeconomic backgrounds. Methods Two birth cohorts respectively born in 1994 in Ribeirao Preto, a wealthy city in Southeast, and in 1997/98 in Sao Luis, a less wealthy city in Northeast of Brasil, were evaluated. After birth, 2,846 pairs of mothers-newborns were evaluated in Ribeirao Preto and 2,542 in Sao Luis. In 2004/05, 790 children aged 10/11 years were randomly reassessed in Ribeirao Preto and 673 at 7/9 years in Sao Luis. Information on type of delivery, maternal and child characteristics, socioeconomic position and anthropometric measurements were collected after birth and at school age. Obesity was defined as BMI ≥ 95th percentile at school age. Results Obesity rate was 13.0% in Ribeirao Preto and 2.1% in Sao Luis. Cesarean section was associated with obesity and remained significant after adjustment only in Ribeirao Preto [OR = 1.74 (95% CI: 1.04; 2.92)]. The association between cesarean section and BMI remained significant after adjustment for maternal schooling, maternal smoking during pregnancy, duration of breastfeeding, gender, birth weight and gestational age, type of school and, only in Sao Luis, pre-pregnancy maternal weight. In Ribeirao Preto children born by cesarean section had BMI 0.31 kg/m2 (95%CI: 0.11; 0.51) higher than those born by vaginal delivery. In Sao Luis BMI of children born by cesarean section was 0.28 kg/m2 higher (95%CI: 0.08; 0.49) than those born by vaginal delivery. Conclusion A positive association between cesarean section and increased BMI z-score was demonstrated in areas with different socioeconomic status in a middle-income country.

Magnetotelluric deep soundings, gravity and geoid in the south Sao Francisco craton: Geophysical indicators of cratonic lithosphere rejuvenation and crustal underplating

In the south Sao Francisco craton a circular and 8-m amplitude geoid anomaly coincides with the outcropping terrain of an Archean-Paleoproterozoic basement. Broadband magnetotelluric (MT) data inversions of two radial profiles within the positive geoid and Bouguer gravity anomaly yield geo-electrical crustal sections, whereby the lower crust is locally more conductive (10 to 100 Omega m) in spatial coincidence with a denser lower crust modeled by the gravity data. This anomalous lower crust may have resulted from magmatic underplating, associated with Mesoarchean and Proterozoic episodes of tholeiitic dike intrusion. Long-period MT soundings reveal a low electrical resistivity mantle (20 to 200 Omega m) from depths beyond 120 km. Forward geoid modeling, using the scope of the low electrical resistivity region within the mantle as a constraint, entails a density increase (40 to 50 kg/m(3)) possibly due to Fe enrichment of mantle minerals. However, this factor alone does not explain the observed resistivity. A supplemented presence of small amounts of percolated carbonatite melting (similar to 0.005 vol.%), dissolved water and enhanced oxygen fugacity within the peridotitic mantle are viable agents that could explain the less resistive upper mantle. We propose that metasomatic processes confined in the sub-continental lithospheric mantle foster the conditions for a low degree melting with variable CO(2), H(2)O and Fe content. Even though the precise age of this metasomatism is unknown it might be older than the Early Cretaceous based on the evidence that a high-degree of melting in a lithospheric mantle impregnated with carbonatites originated the tholeiitic dike intrusions dispersed from the southeastern border of the Sao Francisco craton, during the onset of the lithosphere extension and break-up of the western Gondwana. The proxies are the NE Parana and Espinhaco (130 Ma, Ar/Ar ages) tholeiitic dikes, which contain (similar to 3%) carbonatites in their composition. The occurrence of a positive geoid anomaly (+ 10 m) and pre-tholeiites (age > 138 Ma), carbonatites and kimberlites along the west African continental margin (Angola and Namibia) reinforces the presumed age of the Sao Francisco-Congo craton rejuvenation to be prior to its fragmentation in the Lower Cretaceous.

Successional stage and geographic features determine floristic similarity among Atlantic Forest remnants, Sao Paulo State, Brazil

Analysis of floristic similarity relationships between plant communities can detect patterns of species occurrence and also explain conditioning factors. Searching for such patterns, floristic similarity relationships among Atlantic Forest sites situated at Ibiuna Plateau, Sao Paulo state, Brazil, were analyzed by multivariate techniques. Twenty one forest fragments and six sites within a continuous Forest Reserve were included in the analyses. Floristic composition and structure of the tree community (minimum dbh 5 cm) were assessed using the point centered quarter method. Two methods were used for multivariate analysis: Detrended Correspondence Analysis (DCA) and Two-Way Indicator Species Analysis (TWINSPAN). Similarity relationships among the study areas were based on the successional stage of the community and also on spatial proximity. The more similar the successional stage of the communities, the higher the floristic similarity between them, especially if the communities are geographically close. A floristic gradient from north to south was observed, suggesting a transition between biomes, since northern indicator species are mostly heliophytes, occurring also in cerrado vegetation and seasonal semideciduous forest, while southern indicator species are mostly typical ombrophilous and climax species from typical dense evergreen Atlantic Forest.

Costs estimates and rentability of the guava culture {psidium guajava l. patuma cv.) in monte alto county, Sao Paulo state

This work intended to calculate the rentability of the guava culture Paluma cv. in Monte Alto region-SP, estimating the costs of the implantation, maintenance, production and the gross income of this culture in the first three years of cultivation. The production system utilized refers to the cultural treatments usually used in this culture in the region. The costs estimates were based on the total operational costs methodology used by the Agricultural Economics Institute (I.E.A.). The results obtained showed that the implantation and maintenance costs of the culture, in the two first years was Rs7.402,31/alqueire. Considering the possibility that in guava orchard, on irrigated conditions, reach in the fourthy year a productivity of 80t/alqueire and that the current price is Rs0,20/kg, it is possible to estimate the gross income around of Rs16.000,00/alqueire, resulting in a net income of Rs9.497,06/alqueire.

Reproductive biology and moulting cycle of the crab Callinectes ornatus (Decapoda, Portunidae) from the Ubatuba region, Sao Paulo, Brazil

To investigate the reproductive biology of Callinectes ornatus gonadal and moulting cycles were studied over two consecutive years in the Ubatuba region. Six stages of gonadal development were detected in females and four in males. Observations on the number of ovigerous females, on the moulting stages of males and females, and on the percentage of individuals exhibiting mature gonads reveal a continuous reproductive cycle, the stages of which progress at different rates. These data support the hypothesis that C. ornatus shows staggered spawning, with possibly more than one annual reproductive period. A pause in growth before the terminal moult may occur in this species.
