As aves destacam-se dentro dos vertebrados por serem um grupo diverso e adaptado a diferentes ambientes, a composição da comunidade de aves de um determinado local é um importante bioindicador ambiental, pois ela reflete alterações recentes ou pretéritas de determinada área. Na Bacia Hidrográfica do Rio dos Sinos, as pressões sobre os remanescentes de ecossistemas naturais são intensas em decorrência da urbanização crescente, do estabelecimento de indústrias e da ampliação das fronteiras agrícolas, esses fatores associados geram a redução e fragmentação de habitats, com impactos irrecuperáveis para a flora e a fauna. Devido à escassez de dados sobre a avifauna do município de Taquara, o presente estudo teve como objetivo levantar informações sobre o grupo, listando as espécies de aves locais. Entre agosto de 2016 e junho de 2017 foram realizadas quatro amostragens mensais em duas áreas rurais do município, totalizando 44 campanhas de observação e 132 horas de esforço amostral. As espécies foram identificadas e classificadas conforme sua frequência de ocorrência mensal, em espécies comuns e raras. Foram registradas 133 espécies distribuídas em 47 famílias, o que representa mais de 20% das espécies ocorrentes para o estado. Ao longo do período amostrado, 90 espécies foram classificadas como comuns e 47 consideradas raras para as áreas pesquisadas.Palavras-chave: Aves. Bacia hidrográfica do Rio dos Sinos.

The composition of the bird community of a certain place is an important environmental bioindicator since it reflects recent or previous environmental disturbances of a certain area. In the Sinos River Basin, environmental pressures on the remnants of natural ecosystems are intense as a result of increasing urbanization, the establishment of industries and expansion of agricultural frontiers which generate habitat reduction and fragmentation with irrecoverable damages on flora and fauna. Due to the scarcity of data on the avifauna of the municipality of Taquara, the present study aimed to gather information and list the species of local birds. Between August 2016 and June 2017, four monthly samplings were carried out in two rural areas of the municipality, totaling 44 observation campaigns and 132 hours of sample effort. The species were identified and classified as common and rare according to their frequency of occurrence. There were 133 species distributed in 47 families, representing more than 20% of the species that occurred in the state. During the sampled period, 90 species were classified as common and 47 were considered rare for the areas surveyed.Keywords: Birds. Hydrographic basin of Sinos River. Preservation.

Visceral leishmaniasis (VL) is a zoonosis caused by the protozoan of the genus Leishmania. The disease is transmitted by the bite of a sand fly vector. Although the main reservoirs are dogs, other hosts can be infected and may play this role. Rio Grande do Sul western region, located on the triple border of Brazil-Uruguay-Argentina, represents a VL transmission area. The goal of the present study was to identify Leishmania spp. infection in animals from rural areas of Uruguaiana, Rio Grande do Sul. Nine farms in the Uruguaiana municipality, Rio Grande do Sul state, were included. Peripheral blood samples were collected from 113 animals (canine [n=22], equine [n=91]) for detection of Leishmania spp. DNA was isolated and polymerase chain reaction was performed. Eight (7%) animals with Leishmania spp. infection were detected on two farms in the same geographical area, seven of which were horses and one was canine, all of which were asymptomatic. To investigate the species of Leishmania, one of the positive equine samples was subjected to direct sequencing, which confirmed the presence of L. infantum genetic material. Results of this study confirm the presence of L. infantum-infected animals in rural areas of Uruguaiana, and provide evidence supporting further investigation of risk factors for dissemination in such areas.

The 19Th Century

This article presents an analysis of the process of industrialization and urbanization of the Sinos Valley in Rio Grande do Sul state, Brazil, starting from the establishment of leather goods and footwear manufacturing in the region during the 19th century when tanneries and factories producing footwear and/or components for footwear began to appear, and with special attention to aspects related to the environmental impact on the Sinos river hydrographic basin. The article is based on both bibliographic and documentary research and also draws on biographical narratives of workers with links to the leather goods and footwear industry obtained using ethnographic method. It was found that contemporary environmental conflicts emerge from within a memory of work and an environmental memory in which the factories, the unplanned urbanization, and the utilization of water and other natural resources form a chain of significance. Significance that precludes any form of fragmented analysis that isolates any of these aspects from the others: the economic, socio-historic, cultural, political, or the environmental.

A total of 459 individuals of Atlantoraja cyclophora were captured along the Rio Grande do Sul coast between latitudes 30º40'S and 34º30'S. Two surveys were performed, in the winter 2001 and in the summer/autumn 2002, using bottom-trawl between the depths of 100 and 600 m. This species occurred between 100 and 300 m deep, without significant differences in the frequency of occurrence and abundance (CPUE; kg/hour) between latitudes, depth and seasons. The sex ratio was not significantly different from 1:1 in all depths. In the study area, temperature ranged between 10.0 ºC and 17.6 ºC and salinity between 35.2 e 36.0 ppm. There was no correlation between CPUE and depth, temperature and salinity. Mean total length of females (53.2 cm) was significantly larger than males (50.9 cm). No differences were detected in mean total length between seasons, but mean total length was significantly larger in depths of 100 m and 200 m. The distribution of the frequencies of total length was asymmetric, indicating rareness or lack of juveniles in the samples.

Two new freshwater species of amphipods from Brazil are described here. Hyalella xakriaba n. sp. occurs in the hydrographic basin of the São Francisco River, in a biome characterized by a semiarid climate, in the state of Minas Gerais. This new species constitutes the northernmost record of the genus in Brazil. Hyalella kaingang n. sp. occurs in the hydrographic basin of the Mampituba River, located in Rio Grande do Sul, the southernmost state in Brazil. Currently 14 species of Hyalella are known in Brazil, cave species among them. Some morphological characters and their respective states are analyzed, and constitute an important new tool for species identifications. In particular, we describe the cuticular structures, defined as denticles, on the distal inner margin of the carpus of gnathopods 1 and 2. These structures may have a polygonal pattern or appear as comb scales, and may be arranged in one or more rows.

Abstract Background: Leishmaniasis, zoonotic diseases, are in the top ten list of tropical neglected disease globally. The number of contaminated dogs in South America is estimated in millions of animals and correlated to the human’s cases, especially in Brazil. Equines became infected too and can play a role in the epidemiological chain. Thus, the aim of the present study was to evaluate risk factors to leishmaniasis in rural areas of the western border region of Rio Grande do Sul state, Brazil by Leishmania sp. protozoa molecular detection and serological evaluation (ELISA) in equine and canine blood samples. Methods: This work included nine farms around the city of Uruguaiana. It was collected epidemiologic information regarding farm characteristics and biologic material collection of canine and equine, totalizing 113 samples. The polymerase chain reaction (PCR) technique was used to detect Leishmania spp. in biological samples. Variables related to the farm were collected and evaluated through descriptive analysis followed by chi-square test and a logistic regression analysis.Results: Nineteen positive samples (19/113 – 16,81%) were detected, being 18 equines and 1 canine, in six of the nine farms included in the study. No animal showed clinical signs of the disease. According to the variables analyzed, when compared each characteristic separately, the presence of abundant vegetation and poor hygiene demonstrated to be risk factors to Leishmania infection in rural areas. The logistic regression showed that excellent general hygiene, proximity to the weir and trimmed grass were protective factors (p=0.038, p=0.001 and p=0.014, respectively). Having excellent hygiene represents a 70% lower chance of getting contaminated, keeping the grass cut protects the animal by more than 90% and the proximity of the weir represents a protective factor of 96%.Conclusions: The presence of leishmaniasis in the western border region of Rio Grande do Sul was 16,81% and it was influence by farm characteristics. The role of the excellent general hygiene as a protective factor is extremally relevant in the leishmaniosis prevention.

Two Stages

Tourism in São Francisco de Paula, in Rio Grande do Sul [Brazil] has stood out and, due to its wide territory, the need to organize tourism in rural areas emerges. Otherwise, socioeconomic and environmental sustainability may be weakened, if the presence of tourism activity is disordered. Thus, tourist routing can be an ally in promoting local, sustainable development. Therefore, the objective of this study was to develop a roadmap for rural tourism in São Francisco de Paula. The first step towards achieving this goal involved examining documents to obtain an overview of local tourism. The next two stages took place through a specific questionnaire addressed to entrepreneurs and tourists. Based on the data collected, an instrument for sustainable regional development was developed: a rural roadmap called ‘Encantos de São Chico’. The survey shows that both owners and tourists recognize the relevance of rural tourism to sustainable local development.
