Este trabalho teve como objetivos determinar a relação de variáveis morfométricas e de índices de competição com o crescimento em diâmetro de Trichilia claussenii, em um fragmento da Floresta Estacional Semidecidual na região central do Rio Grande do Sul. Os dados utilizados neste estudo foram obtidos de 29 árvores amostradas por classe diamétrica, denominadas árvores centrais, com diâmetro à altura do peito (d) igual ou superior a 10,0 centímetros, distribuídas em 51 parcelas permanentes, totalizando 0,51 hectares. Cada árvore central teve as seguintes variáveis mensuradas: altura total e altura comercial do fuste, diâmetro à altura do peito, diâmetro da copa e comprimento de copa. Posteriormente, calcularam-se alguns parâmetros morfométricos, assim como alguns índices de competição dependentes e independentes da distância. A análise de correlação de Pearson e análise de regressão foram utilizadas para verificar a relação entre as variáveis morfométricas, os índices de competição e o incremento em diâmetro. Concluiu-se que existe associação entre o incremento em diâmetro de Trichilia claussenii e a competição, sendo que o crescimento em diâmetro possui maior relação com o índice Bal de competição.Palavras-chave: Catiguá; floresta nativa; biometria florestal. AbstractRelationship of morphometry and competition with growth of Trichilia claussenii in fragment of Semidecidual Forest, RS. This study aimed to determine the relationship of morphometric variables and indices of competition with the growth in diameter of Trichilia claussenii, in a fragment of semideciduous forest in the central region of Rio Grande do Sul. The data used in this study were obtained from 29 sampled trees by diameter class, called central trees with diameter at breast height (d) not less than 10.0 cm, from 51 permanent plots, totaling 0.51 ha. Each central tree had measured the following variables: total height and commercial height, stem diameter at breast height, crown diameter and crown length. Subsequently, it was calculated some morphometric parameters, as well as some competition indexes dependent and independent of distance. The Pearson correlation analysis and regression analysis were used to verify the relationship between the morphometric variables, competition indexes and diameter increment. It was concluded that there is an association between the increase in diameter of Trichilia claussenii and competition, where the growth in diameter has a greater relationship with Bal index of competition.Keywords: Catigua; native forest; forest biometrics.

The relationship intensity, duration and frequency is very important for the hydraulic project’s development, mainly in regions where there is no study updated data. This paper objective was to determine the intensity-duration-frequency curves at Rio Grande do Sul hillside, in order to provide tools for hydraulic structures design and hydrological studies in the region. For the return periods 2, 5, 10, 20, 25, 50 and 100 - year precipitation determination was used Gumbel’s and log-normal statistical distributions, using the Rain Relationship Duration Method for 20 rainfall stations. For Gumbel’s distribution data adherence verification, was used the Kolmogorov-Smirnov adhesion tests and Chi-Square adhesion, with, 5% significance level. The general IDF equation coefficients a, b, c and d were obtained through non-linear regression and the adjustment quality was measured by both determination coefficient and standard error. Different intense rainfall curves were obtained with the methodology applied, for the region, each one shows a good parameters adjustment, important tool for extreme precipitations estimating.

Основными исходными данными для определения запаса служат результаты обмеров диаметров и высот деревьев. Но обмеры диаметров деревьев на высоте груди выполнить намного проще, чем обмеры высот, поэтому ограничиваются замерами высот 15–25 деревьев. Цель исследования – по материалам измерения модельных деревьев в сосновых древостоях выбрать наиболее адекватную простую модель, которая передает зависимость между высотой деревьев и диаметром на высоте груди. Объектом исследования послужили сосновые древостои искусственного происхождения на постоянных пробных площадях в Лесной опытной даче Российского государственного агарного университета – МСХА имени К.А. Тимирязева. В работе используются данные обмеров деревьев на 17 постоянных пробных площадях с 1934 по 2005 гг. Возраст древостоев на момент проведения измерений от 50 до 125 лет. По итогам проведения 77 перечетов массив данных составил 1157 наблюдений. И модель фиксированных эффектов, и модель смешанных эффектов адекватно описали зависимость между высотами и диаметрами деревьев в культурах сосны. Но, как и ожидалось, первая модель имеет худшие значения метрик качества по сравнению со второй. Модель со смешанными эффектами более точно предсказывает значения высот по сравнению с моделью фиксированных эффектов. Недостающие значения высот большого количества деревьев на участке можно вычислить более точно с помощью модели смешанных эффектов, а не применения модели фиксированных эффектов или использования только фиксированной части (средний отклик) модели смешанных эффектов. Применение разработанной модели должно ограничиваться только в тех условиях, к которым относятся экспериментальные материалы The main data for the stock of research results is the diameter of measurements and heights of trees. But measurements of the diameter at breast height are much easier to perform than measurements of heights, therefore, they are limited to measuring the heights of 15–25 trees. The aim of the study is to select the most adequate simple model based on the measurements of model trees in pine antiquities, which conveys the relationship between the height of trees and the diameter at breast height. The object of the study was pine stands of artificial origin on permanent test plots in the Forest Experimental Station Russian State Agararian University – Moscow Timiriazev Agricultural Academy. The work uses data from tree measurements on 17 permanent sample plots from 1934 to 2005. The age of the stands at the time of measurements was from 50 to 125 years. As a result of 77 enumerations, the data array amounted to 1157 observations. Both the fixed effects model and the mixed effects model adequately describe the relationship between heights and diameters of trees in pine stumps. But, as expected, the first model has worse quality metrics than the second. The mixed effects model more accurately predicts heights from the fixed effects model. The missing heights of a large number of trees on a site can be calculated accurately using mixed effects models, rather than using fixed effects models or using only a fixed portion (mean response) of the mixed effects model. The application of the developed model should be limited only in those conditions to which the experimental materials are applied.

The goal of this work was to calculate landscape ecology metrics using the R language, allowing the analysis of forest fragments under the Atlantic Forest domain located in the sub-basin of Arroio Jaquirana, Rio Grande do Sul, Brazil. For the mapping of the forest fragments, we used images from the REIS/RapidEye sensor dated 2016, and the classification was supervised through the Bhattacharya algorithm. The fragments were analyzed in seven size classes, to separate them and to calculate the landscape metrics it was used R language. The results attained demonstrated that the native forest occupied 34.01% of the study area, covering a total of 1,995 fragments, of which 93.43% were less than 5 ha. The highest values of edge and perimeter-area ratio were found in the small fragments indicating a greater edge effect, with the central areas of these remnants being exposed to the external matrix effects. Thus, it is concluded that the Atlantic Forest is highly fragmented and is extremely important to establish measures to minimize the effects and/or increase the connectivity between the fragments through ecological corridors using the smaller fragments, in addition, it makes necessary the development of public policies and research for the management of the region in order to preserve the remnants.

A cidade de Rio Grande ocupa o segundo lugar nos registros de câncer da pele no Estado do Rio Grande do Sul. Este estudo visa investigar o perfil epidemiológico dos atendidos pelas Campanhas de Prevenção ao Câncer de Pele de 2010, 2011 e 2012 realizadas em Rio Grande. Para isso foram realizadas observações participantes e semidirigidas. Foi demonstrado que foram mulheres brancas e pardas quem mais participaram e que os homens estão em um processo crescente de participação. Dos participantes, no mínimo 50% expõem-se ao sol sem qualquer proteção, principalmente por suas atividades ocupacionais. Foi constatado que o uso de protetores solares está bem aquém do necessário, sendo que em 2010 e 2011 os percentuais de indivíduos que não fizeram uso de protetores solares foi de 53,01% e 45,58%, respectivamente. Dicotomicamente, foram semelhantes os percentuais de quem nunca teve história de queimaduras solares ao longo da vida e daqueles que tiveram mais de três episódios, bem como os percentuais de quem não teve e de quem já teve história prévia de câncer de pele. Foi praticamente consenso a importância de conhecer os índices de radiação ultravioleta diário e seus riscos à saúde e que é a escola a fonte mais apropriada para divulgar e trabalhar informações sobre este tema. Nossos dados permitem propor políticas educacionais e sociais sobre a relação entre a exposição à radiação ultravioleta e o câncer de pele. Prevention Campaign Against Skin Cancer in Rio Grande, Brazil: An Epidemiological Profile ABSTRACT: The city of Rio Grande ranks second in skin cancer in the state of Rio Grande do Sul, Brazil. Current study investigates the epidemiological profile of people attended to in the campaign against skin cancer in Rio Grande in 2010, 2011 and 2012. Participating and semi-directed observations were undertaken. White and brown-skinned females participated most, although males were on the increase. At least, 50% of the participating population expose themselves to the sun without any protection, especially during their occupational activities. Solar protection is not sufficiently used: in 2010 and 2011, the percentages of people who failed to use solar protectors were respectively 53.01% and 45.58%. Contrastingly, percentages were similar to those who never had sun burns and those with more than three episodes, similar to percentages of who never had and who had a previous skin cancer episode. All agreed on the importance of being informed on daily UV radiation and health risks. All agree that the school is the most appropriate place to disseminate information and discuss such issues. Data suggest educational and social policies on the relationship between exposure to UV radiation and skin cancer.

O orçamento público é um dos instrumentos utilizados pela Administração Pública para garantir o atendimento das demandas sociais. Entretanto, para que estas demandas sejam conhecidas do Poder Público, torna-se necessária a participação da sociedade nos eventos públicos destinados à discussão para elaboração dos instrumentos orçamentários. Este artigo realiza um apanhado teórico sobre conceitos pertinentes ao tema, realizando inclusive o estudo da participação social na elaboração do PPA 2014-2017 do Município de Ijuí, Rio Grande do Sul. Para enriquecer a abordagem da pesquisa, foram aplicados questionários online, buscando identificar a relação entre os cidadãos ijuienses e Administração Pública municipal. Foi possível perceber a falta de interesse dos indivíduos em relação à participação em eventos destinados a discussões públicas sobre o processo de elaboração do orçamento municipal e, neste sentido, ao final deste estudo são realizadas proposições, que poderão auxiliar na construção de uma consciência coletiva acerca da relevância da participação social na construção dos instrumentos de planejamento e orçamento.Palavras-chave: Gestão Municipal.

Studies on the thermal biology of fossorial reptiles that examine the relationship between the body temperature and thermal environment are needed to determine the extent of their thermoregulation abilities. This study assessed the thermal biology of Amphisbaena munoai Klappenbach, 1969 in the rocky fields of the Rio Grande do Sul and in the laboratory. The body temperature of most individuals was between 24 and 30 °C, both in the field (n = 81) and laboratory (n = 19). More individuals were caught in winter (n = 55) and spring (n = 60) than in summer (n = 25) and fall (n = 45), and in spring, individuals showed similar nocturnal and diurnal activities. In the laboratory, we found individuals with body temperatures up to 5 °C higher than the ambient temperature (n = 4), suggesting that some physiological mechanisms participate in the thermoregulation of these animals. Amphisbaena munoai is a thigmothermic species that is capable of actively regulating its temperature by selecting microhabitats such that its various activities occur within an ideal temperature range. This study is the first to evaluate the effect of seasonality and diurnal and nocturnal variations on the thermoregulation of an amphisbaenid.
