title: Morphological changes in the hydrographic basin of the Córrego Barreiro throughout the urbanization process, Goiânia - GO

description: Abstract This work aimed to evaluate the process of urban occupation and its influence on the morphological behavior of the Barreiro Creek Basin, located in Goiânia - GO, analyzing its current arrangements for use in contrast with the characteristics of different periods of the physical environment. The methodology adopted evaluated the space-time between changes in coverage and urban land use/land cover (LULC) between 2006, 2012, 2016 and 2019 and the behavior of the channel morphology, in view of the increase in waterproofing rates. The classes Waterproof, Non-permeable, Green Area, exposed were identified, while the class Non-permeable presented a drop and the class Green Area presented several answers. The increase of the Solo exposed class is related to the growth of the urban area in the study basin. A granulometric analysis of soil samples was also performed and the analyses showed a greater presence of sand followed by silt, configuring materials with light texture, which disintegrate easily and are loaded with flow. The results indicate how the impacts of urbanization interfere with the watershed.

title: AUTOMATIC DETECTION OF PLANTED TREES AND THEIR HEIGHTS USING PHOTOGRAMMETRIC RPA POINT CLOUDS

description: Abstract: This work aims to analyze the potential of the Photogrammetric Point Cloud (PPC) obtained from Remote Piloted Aircraft (RPA) optical images for detecting and obtaining tree heights in a loblolly pine plantation using a global maximum filter. The enhanced algorithm used in this study is then named STD (Single Tree Detection). Field surveys were conducted to count all the trees in the field (Forest Census) and measure the trees’ height with a vertex hypsometer. The results were faced to PCC outcomes. The detection rate (r) was equal to the precision rate (p), indicating that the algorithm reaches a high tree detection performance. In summary, the STD algorithm segmented 2,192 trees, representing 89% of trees recorded in the forest census. The retrieved tree height reached, on average, a height of 17.05 m, whereas slightly higher by the traditional forest inventory (17.42 m). The root-mean-square error (RMSE) and Bias were 47 cm (2.8%) and -37 cm (-2.2%), respectively. The Dunnett test showed that the tree height did not significantly differ between the results obtained by traditional forest inventory from those generated by the STD. It confirms the potential use of PPC for forest inventory procedures.

title: Biotic differentiation in headwater creeks after the massive introduction of non-native freshwater aquarium fish in the Paraíba do Sul River basin, Brazil

description: Abstract This study evaluated fish beta diversity in six headwater creeks located in the area affected by the largest ornamental aquaculture center implemented in the Minas Gerais State, southeastern Brazil. We sampled fish assemblages in 2017 and 2018 to investigate changes in assemblage structure (species richness and beta diversity), comparing these data with the historic species pool. We recorded 60 fish species, of which 16 were native and 44 non-native with 19 translocated, and 25 exotic. The exotics Poecilia reticulata, Xiphophorus maculatus, X. variatus, Danio rerio, and Misgurnus anguillicaudatus were the most widely distributed in the headwater creeks. The Contamination Index showed that most creeks had high proportional contamination by exotic species (above 60%). Beta diversity increased from historical to contemporary periods in all creeks due to the introduction and differential colonization pressure of several non-native translocated and exotic species, indicating biotic differentiation. Temperature and number of ponds were the main preditors of change in beta diversity in the headwater creeks during the contemporary period. In summary, we observed that invaders have induced substantial changes to fish communities under influence of environmental filters. Our results support the hipothesis that aquaculture is a main driver of fish non-native fish introduction and native biodiversity loss in the Neotropics.

title: ACADEMIC ADAPTATION TO THE UNIVERSITY: RELATIONSHIPS AMONG MOTIVATION, EXPECTATIONS AND SOCIAL SKILLS

description: ABSTRACT The study related academic expectations, motivation, social skills and academic adaptation and verified the impact of the first three variables on university adaptation. 320 students of different degrees participated. The Motivation Scale, the Social Skills Inventory, the Academic Expectations Scale and the Reduced Academic Experiences Questionnaire were used. Data collection took place in loco and Pearson correlation and multiple linear regression were used. All ethical procedures were followed. The results showed a predictive relationship of the variables in the total score of academic adaptation. It is understood that expectations met in terms of an enriching learning environment as well as the development of social skills promote academic adaptation and professional and personal growth. The study showed that expectations allow us to indicate the determining factors in the process of adapting to Higher Education. Prospective research can consider sociodemographic data and the fact that the student is from public and private institutions.

title: INNOVATING IN UNIVERSITY: A REAL ALTERNATIVE OR ALWAYS THE SAME THING?

description: ABSTRACT Research in the educational field on implicit theories suggests that the nature of innovations in university teaching contexts depends, to a large extent, on what theories teachers have constructed about what it means to learn, teach and innovate. Our main objective was to analyze the implicit theories of a group of twelve professors who presented innovation projects in a Chilean university. Following a qualitative approach, in-depth interviews were conducted with each of these teachers, who were responsible for the projects. Our results suggest that teachers conceive learning, teaching and innovation from a series of constructivist notions. However, at the moment of foreseeing the instructional design of their projects they fail on identifying the manner in which these aspects should be concretized in practice. We discuss implications of these results for both research and educational practices.

title: Adaptability and stability with multivariate definition of macroenvironments for wheat yield in Rio Grande do Sul

description: Abstract: The objective of this work was to evaluate the adaptability, stability, and environmental stratification of wheat (Triticum aestivum) grown in 20 environments, in the state of Rio Grande do Sul, Brazil. The experiments were performed during four crop years, in five wheat growing regions, considering 20 distinct growing environments. In the presence of genotype x environment (GxE) interaction, the additive main effects and multiplicative interaction analysis (AMMI) method was used. This method combines variances of additive effects of genotypes and environments with the multiplicative effects of GxE interaction, and the obtained scores are displayed in biplot graphs, using the principal component analysis. The environments stratified by the factor analysis, and the macroenvironments were defined according to grain yield behavior. The patterns of adaptability and phenotypic stability for genotypes 'BRS 327', 'BRS 331', 'Fundacep Raízes', 'BRS 328', and 'BRS Guamirim' were obtained through the multivariate biometric approaches AMMI and the factor analysis. The definition of macroenvironments is intrinsic to peculiarities of the crop year in the state of Rio Grande do Sul, and there is similarity between the municipalities of Santo Augusto, Cachoeira do Sul, and São Luiz Gonzaga, as well as between Cachoeira do Sul and São Gabriel.

title: Brazilian cities: between values and narratives of urbanism

description: Abstract The old Brazilian cities, constituted in the colonial period, have urban spaces with characteristics linked to Portuguese urban traditions, but still, they allow different readings and interpretations due to their singularities related to the location in the country, especially between interior and coast. Throughout the 20th century, these singularities favored the formulation of different narratives about these cities, with publications that did not always consider such urban characteristics from different perspectives, attributing negative and positive values to them. In order to demonstrate the epistemological process of construction of these narratives, some temporal milestones are pointed out, such as 1930, 1960 and 2000. These milestones were established, for the purposes of this study, to guide the contexts of these narratives and the values involved, based on Boaventura de Souza Santos and his contributions on common sense and science. From bibliographic and documentary research, examples of some coastal cities and case studies in the interior city of Ouro Preto, Minas Gerais, were pointed out, due to the ways in which the processes of constitution of their spaces are presented in the bibliography. As a result, this article demonstrates how the different values related to the historical context of the old Brazilian cities were transposed between common sense and science through some predominant narratives.

title: Protection of spawning habitat for potamodromous fish, an urgent need for the hydropower planning in the Andes

description: Abstract Because dams block migratory routes of potamodromous fish to their spawning areas, and energy generation changes natural flow seasonality, it is necessary to identify spawning areas and their conditions. This information will help in management decisions in the Magdalena River basin regarding the future hydropower development. We identified which characteristics of the tributaries to the Magdalena River are important for determining potamodromous fish spawning grounds, and we estimated the percentage of future loss of spawning areas because of dam development. Ichthyoplankton density is directly related to the floodplain area, and inversely related with channel slope. Low channel slopes offer adult fish a longer distance for their upstream migration and a longer time for embryo development during their drift downstream from the spawning areas to nursery habitats (floodplain lakes). These features could increase the migration distance of the adults, the time for initial embryo development, and, because of its relationship with nursery habitats access, the offspring survival. The potential loss of the actual spawning grounds in the river network was estimated to be nearly 70% because of new dams. Our findings will help to reduce conflicts between hydropower and ecological interests.

title: A modelling approach to simulate Chlorophyta and Cyanobacteria biomasses based on historical data of a Brazilian urban reservoir

description: Abstract A process-based model was used to simulate a hindcast based on the worst historical water quality condition of a tropical urban reservoir. Paranoá Lake is located in Brasília-DF, Brazil, and went through intense eutrophication in the 70s and 90s, with an important cyanobacterial bloom event in 1978. The parameters of phytoplankton were calibrated, focusing on the group of Chlorophyta (green algae) and Cyanobacteria (blue-green algae) at four depths (1, 10, 15 and 20m). The results indicated that the model was able to reproduce the Cyanobacteria biomass in comparison with the observations (RMSE=22-29.10-3 mgC L-1). On the other hand, the simulated Chlorophyta biomass showed good agreement with the observed data only in the bottom layer (RMSE=29. 10-3 mgC L-1 at 20m). In the hindcast simulation, the model was able to predict a significant increase in cyanobacterial biomass facing a water quality deterioration. In the meantime, the simulated Chlorophyta biomass decreased, which may indicate the phytoplankton group succession in response to the environmental conditions.
