The first large-scale survey of Fusarium head blight (FHB) in commercial wheat fields in southern Brazil was conducted over three years (2009 to 2011). The objectives were to: (i) evaluate whether increased FHB risk is associated with within-field maize residue; (ii) determine the spatial pattern of FHB incidence; and (iii) quantify the relationship between FHB incidence and severity. FHB was assessed in a total of 160 fields between early milk and dough. Incidence ranged from 1.0 to 89.9% (median = 25%) and severity from 0.02 to 18.6% (median = 1.3%). FHB risk was neither lower nor higher in wheat following maize than in wheat following soybean. Only 18% of fields were classified as having aggregated patterns of FHB-symptomatic spikes. A binary power law description of the variances was consistent with an overall random pattern of the disease. These results conform with the hypothesis that FHB epidemics in southern Brazil are driven by sufficient atmospherically-transported inoculum from regional sources. The incidence-severity relationship was coherent across growing season, growth stage, and previous crop; one common fitted curve described the relationship across all observations. Estimating severity from incidence may be useful in reducing the workload in epidemiological surveys.

Objetivo: O objetivo deste estudo foi identificar as plantas medicinais utilizadas como analgésicas por famílias descendentes de pomeranos no Sul do Brasil. Métodos: Trata-se de um estudo qualitativo, realizado com cinco famílias de agricultores. O local do estudo foi o domicílio das famílias, localizadas na zona rural, sendo os dados coletados entre janeiro e maio de 2011. Os instrumentos utilizados foram a aplicação de uma entrevista semi-estruturada e levantamento etnobotânico das plantas medicinais utilizadas como analgésicas, que posteriormente foram identificadas taxonomicamente. Resultados: Foram citadas 105 plantas medicinais, das quais 20 são utilizadas como analgésicas. Conclusão: Observa-se que grande parte das plantas medicinais citadas como analgésicas pelas famílias não possuem este efeito comprovado, por outro lado, estas mesmas plantas possuem outros efeitos terapêuticos capazes de provocar alterações no organismo. Com isso, cabe aos profissionais de saúde estar atentos sobre as medidas de cuidado adotadas pelas pessoas. Descritores: Plantas medicinais, Analgésicos, Etnobotânica.

The aim of this study was to determine the feasibility of combining water quality analysis with different biomarkers to characterise the relationship between anthropogenic contamination and biotic response in the Sinos River, southern Brazil. Wistar rats were studied using three biomarkers combined with physical, chemical and microbiological analysis to assess the effects of pollution at four sampling sites. The induction of oxidative stress was quantified by MDA levels in peripheral blood, lymphocyte DNA damage was determined using the comet assay, and histopathological changes were analysed in the liver. After sampling, animals were allowed to drink the river water during a 48 hours period. No increase in oxidative stress and DNA damage was observed. However, liver damage was observed in the animals exposed to water samples, indicating that the Sinos River is contaminated with hepatotoxic substances. Water analyses confirmed that water quality decreased downriver.

Abstract This article examines postmortem inventories and notarial records from Brazilian slaveholders in southern Brazil in the nineteenth century. By discussing selected cases in detail, it investigates the relationship between “precarious masters” (especially the poor and/or disabled, widows without family, and single elderly slaveholding women and men) and their slaves and former slaves to whom they bequeathed, in their testaments and final wills, manumission and property. The article reads these documents as intergenerational contractual arrangements that connected the masters’ expectations for care in illness and old age with the slaves’ and former slaves’ expectations for compensation for their work and dedication. Following these uneven relationships of interdependence and exploitation as they developed over time, the article suggests a reassessment of the role of paternalism in Brazil during the country’s final century of slavery. More than a tool to enforce relations of domination, paternalism articulated with the dynamics of vulnerability and interdependency as they changed over the life courses of both enslaved people and slave owners. This article shows how human aging became a terrain of negotiation and struggle as Brazilian slave society transformed throughout the nineteenth century.

To investigate the relationship between breastfeeding and breast cancer in Southern Brazil, a case-control design was employed, with two age-matched control groups. A total of 250 cases of breast cancer were identified in women from 20 to 60 years of age, with 1,020 hospital and community controls. The main study variables were occurrence of breastfeeding and duration of breastfeeding. A multivariate conditional logistic regression analysis was employed. According to the results, breastfeeding did not have a protective effect against breast cancer. The odds ratio (OR) for women who breastfed was 0.9 (95% CI: 0.8-1.2) compared to women who did not breastfeed. For women who breastfed for six months or less, the OR was 1.0 (95% CI: 0.6-1.8). In pre-menopausal women who breastfed for more than 25 months, the OR was 0.95 (95% CI: 0.5-3.5), and in post-menopausal women OR was 1.27 (95% CI: 0.5-3.1), compared to women who had not breastfeed.

Ornithodoros brasiliensis is an endemic tick from Brazil and is very aggressive to humans, resulting in pain, fever andintense inflammatory response. After more than 50 years without report, this species was recently found in rural areas ofSão Francisco de Paula municipality, State of Rio Grande do Sul, southern Brazil, from where it was originally described.Herein, we describe the larva and redescribe the adults of O. brasiliensis based on scanning electron microscopy. Sincethe type was lost we designate the neotype specimen under the number IBSP 10409. In addition, the relationship betweenO. brasiliensis and other species from the Neotropical region that share the morphological characteristics of Ornithodoroswith dorsal humps on tarsi, and also live under the soil and feed on hosts other than bats, are discussed. Molecular analysisinferred from a portion of the 16S rRNA mitochondrial gene is also provided and it placed O. brasiliensis in a cluster sup-ported by a maximal bootstrap value (100%) with Ornithodoros parkeri, Ornithodoros rostratus, and Ornithodoros turicata.

Studies on fish assemblages in streams point out, that understanding the relationship between species and their environment is crucial for conservation. The present study aimed at evaluating the effects of changes in abiotic variables on the composition and structure of fish assemblages in Neotropical urban streams from southern Brazil with different levels of urbanization. The composition and structure of fish assemblages showed significant differences along the urbanization gradient observed in the streams. Tolerant and non-native species were found in more urbanized sites. A matrix correlation revealed a relationship between abiotic variables and the spatial pattern of structure and composition of fish assemblages. Abiotic variables, such as total phosphorus, dissolved oxygen, and conductivity, determined the distribution of fish assemblages. Streams without urban influence exhibited intrinsically low species richness, suggesting that they are highly susceptible to species loss and diversity reduction. Thus, changes in water quality or hydrological conditions induced by urbanization may intensify these impacts.

A fronteira sul do Império brasileiro foi palco de constantes conflitos. Seja entre os luso-brasileiros e o Império espanhol, entre os brasileiros e orientais ou argentinos, seja a Guerra do Paraguai, a região teve poucos momentos de paz ao longo do século XIX. Do mesmo modo, durante o Oitocentos, o regramento sobre o sistema escravista brasileiro sofreu importantes percalços, como o fim do tráfico em 1850 e a Lei do Ventre Livre em 1871. No Brasil meridional, a abolição da escravidão no Uruguai foi outro fator de desestabilização da instituição escravista. Mesmo em meio a estas contendas e mesmo com as mudanças pelas quais passavam as relações escravistas (no Brasil e fora dele), ali se estabeleceu a mais expressiva criação de gado de todo o país. E, mais importante, produção pecuária que tinha na mão de obra escrava algo estruturante de sua organização. É neste contexto que estudamos a relação entre fronteira e escravidão no presente artigo. Nele, buscamos entender como senhores e escravos lidavam com o espaço fronteiriço, utilizando tal aspecto em seu benefício. Foi possível identificar que a fronteira ora servia para que cada um dos polos buscasse seus objetivos, ora para forjar acordos entre eles, sendo sempre um fator fundante das relações ali produzidas.Palavras-chave: Escravidão. Brasil meridional. Fronteira.ABSTRACTThe southern border of the Brazilian Empire was the scene of constant conflicts. Between the Luso-Brazilians and the Spanish Empire, between the Brazilians and the Orientals or the Argentines, or the Paraguayan War, the region had few moments of peace during the nineteenth century. Likewise, during the nineteenth century, the rule on the Brazilian slave system suffered major setbacks, such as the end of trafficking in 1850 and the Free Womb Law in 1871. In southern Brazil, the abolition of slavery in Uruguay was another destabilizing factor of the slave institution. Even in the midst of these struggles, and even with the changes through which slave relations passed (in Brazil and elsewhere), there was established the most expressive cattle breeding in the whole country. And, more important, livestock production that had on the labor slave something structuring of its organization. It is in this context that we study the relationship between frontier and slavery in this article. In it, we sought to understand masters and slaves dealing with the frontier space, using such aspect to their advantage. It was possible to identify that the frontier now served for each of the poles to pursue their objectives, sometimes served to forge agreements between them, always being a founding factor of the relations produced there.Keywords: Slavery. Southern Brazil. Border.
