We suggest future studies in this environment, once it has propitious characteristics to the development of epilithic diatoms. Moreover, phylogenetic studies are also recommended for a better distinction of taxa with a wide morphologic variation.

Associating anthropogenic effects with variations in biodiversity is key to understanding how anthropogenic impacts are extrapolated in public supply micro-watersheds. The structure and dynamics of metacommunities in aquatic environments depend not only on the river network itself, but on a multitude of factors. Therefore, we associate the density and species richness of diatoms, assessed in a micro-watershed, with the following driver factors: local environmental variables, spatial variables, landscape characteristics, and the historical community, comparing their possible dispersal routes. Variance partitioning was performed using partial RDA models, with prior selection of predictor variables, to estimate the relative role of each predictor in the diatom community. The small scale of the micro-watershed resulted in a small spatial gradient, reflecting in the low variation in community richness across sampling stations. However, temporal heterogeneity associated with fluctuating precipitation throughout the year may cause temporal variation in the relative abundance of species. This pattern is a result of the supply of resources that increases biodiversity over time, as it allows the coexistence of species that alternate between dominance and persistence. Thus, even on a small scale and during one year of sampling, we demonstrated that predictors of different natures act together to explain diatom communities in micro-watersheds.

The evaluation of biotic integrity through multimetric analysis of the attributes of fish fauna is recognized as an important tool for water management and conservation policies. In this sense, the present study sought to elucidate tendencies in the use of the most used metrics in multimetric indices (MMIs), based on the fish assemblage, in Brazil. An electronic search of the literature was carried out in indexing databases of periodicals. The criteria used for the selection of scientific articles were to be carried out in Brazilian territory and the use of MMI with fish. Of total, 51.9% of the studies were applied in streams, with no temporal pattern. The highest concentration of studies was observed in the southeast region. In all, 99 different metrics were used, highlighting attributes related to trophic, tolerance and species composition. There was a increment of specific metrics over the years and environments, with the exception of rivers. In comparison to other environments, streams had significantly different metrics. Difficulties in the MMI proposal in Brazil are linked to the selection of aspects that characterize the condition of a habitat before the diagnosis of the ecological components in the classification of the environmental quality.

Aim: The aim of this study was to assess the taxonomic aspects and geographical distribution of the periphytic desmids from two different substrates in the littoral zone of an urban artificial lake. Methods Samples of epiphytic and epilithic desmids were collected by grass and rock scraping, respectively, in two stations in the Cascavel municipal lake, Paraná, during April 2015, and March 2016 and 2017. In the laboratory, the taxa obtained from the samples were photographed and their morphometric characteristics recorded. The species composition of the desmid was characterized, and the frequency of occurrence as well as the geographic distribution of each taxon in the Paraná State were recorded. Results We identified 35 taxa, distributed in 10 genera. The most representative were Closterium Nitzsch ex Ralfs and Cosmarium Corda ex Ralfs. A high occurrence of sporadic taxa (60%) was observed and among the recorded taxa, the most frequent were Cosmarium pseudoconnatum Nordstedt var. pseudoconnatum and Desmidium grevillei (Kützing ex Ralfs) De Bary. Nine taxa were exclusive to the epilithic substrate and only Netrium digitus (Ralfs) Itzigsohn & Rothe var. digitus was exclusive to the epiphytic substrate, while the remaining 25 taxa occurred in both substrates. Seven taxa are new records for the Paraná State. Conclusion Although our results are of qualitative nature, they provide baseline data on the biogeographic distribution of taxa, which are crucial for future taxonomic and ecological studies that might contribute to the preservation of the biodiversity.

SUMMARY Multidisciplinary teams are increasingly employed to treat cancer patients. This study aimed to evaluate the perception of physicians, other health care professionals, and hospitalized oncological patients regarding the multidisciplinary teams of the public and private sector. In total, 18 doctors were interviewed; 63 health professionals and 120 cancer patients. Satisfaction with the work of the multidisciplinary team was positive among patients and physicians (averages of 89.4% and 66.82% respectively), but higher among patients (p <0.0001), among women rather than men (averages of 77.5% and 85.21% respectively, p < 0.0001), elderly individuals in comparison with adults (averages of 91.98% and 76.01% respectively, p <0.0001), and in the public sector in comparison with the private sector (averages of 83.12 and 70.74 respectively, p < 0.0001). The results demonstrate that despite the difference between groups, patients and members of multidisciplinary groups were satisfied with multidisciplinary care, and some groups, such as elderly women from public services, may especially benefit from multi-professional groups.

Applying environmental fragility in studies evaluating watershed can guide policy decisions on monitoring and management regarding soil use planning, improving water quality for public supply. The objective of this study is to characterize the environmental fragility as well as to relate it to water quality factors of catchment rivers for public supply in western Paraná, Brazil, in order to evaluate the in uence of anthropic actions on catchment sources. Water quality data such as temperature (Temp; C), electrical conductivity (Ec; mS/cm −1 ), dissolved oxygen (DO; mg L −1 ), turbidity (Turb; NTU) and pH were measured on site by the multi-parameter probe HORIBA brand, model U-5000. Slope data were obtained from the site of the National Institute of Space Research (INPE). Soil use and occupation was performed in the QGis software, with image obtained from the Sentinel 2A Satelite. Köppen-Geiger classi cation was used for the climate type. For the environmental fragility maps, the variables slope, climate, soil use and occupation were analyzed using the QGis raster software calculator. The intermediate fragility class predominates in the nine municipalities studied, making it necessary to manage them aimed at restoration and conservation, and the municipalities that are the largest areas of high fragility class are: Guaraniaçu, Catanduvas and Cascavel, demanding greater attention. The variation in fragility mainly responded to the pH, E. coli and DQO temperature values, which can be strongly associated with the difference in soil use and slope of the areas evaluated.

The search for renewable resources has become necessary for sustainable development. Wind energy is a clean energy source and of global importance, but most studies refer to high altitude and are carried out by researchers in developed countries. In this work, the objective was to evaluate the potential of micro and mini-generation (low heights) wind power in Cascavel-PR, a city located in southern Brazil, as an example of the application of the proposed methodology. For this purpose, wind speed and direction data were used, with a historical series of 21 years (1997-2017). The land use and occupation were performed in a semi-automatic way using Sentinel-2 satellite images. To generate the maps, an algorithm was created in Spring software, which correlated the land use and land cover information, the wind speed kriging and the formula coefficient values according to the identified obstacles. With this it was possible to conclude that regarding the period, spring is considered the season of the year with the greatest energy potential, where the highest averages for speed and power were estimated. It was also noted that the 40-meter-high range has the greatest potential and that the prevailing winds come from the northeast.
