Manganese dioxide was synthesized by a microwave-hydrothermal method using alternative, unprecedented and completely soluble reagents. For such, potassium permanganate and acetone were dissolved in different proportions (4:1,5; 4:3; 4:4 and 4:7,) and treated in a microwave reactor, under magnetic stirring, at different temperatures (100, 140 and 160 °C), synthesis times (1, 3, 5 and 10 min) and porcentage of the vessel volume occupied by the reactional mixture (60 and 80%). The obtained materials have been characterized by X-ray diffraction, scanning and transmission electron microscopies, electron diffraction, thermogravimetry, determination of specific area, cyclic voltammetry, and charge and discharge at constant current. The X-ray diffractogramms of the evaluated materials were associated with the JCPDS card number 421317 for MnO2 phase potassium birnessita. The synthesized materials also presented, according to others characterization analyses, nanosized particles (with hierarchical structure), presence of adsorbed and crystalline water and a specific area of 108 m2 g–1, being desirable features for electrode materials of supercapacitors. In order to improve the reproducibility of specific capacitance (c) values the electrodes preparation methodology was also studied. The best results were obtained for electrodes containing 75% MnO2, 20% acetylene black and 5% PVDF confectioned by the methodology of dropping followed by spinning and using a acetylene black of lower average particle size. The product of the synthesis performed at 100 °C over 10 min with the reactional vessel filled with 60% of its total capacity presented the best results as active material for supercapacitor electrode, with a c value of (17 ± 1) x 101 F g–1 (0,2 g–1 ) and a charge retention of 81 % after 5000 charge and discharge cycles at 1 A g–1.

The reflection about social practices in an urban context marked by the permanent deterioration of the built environment and its ecosystem can not dispense with the analysis of the determining factors of the process and its actors and of the forms of social organization. This study evaluated whether the Law of Areas of Protection and Recovery of Waters (APRW) that contributed significantly to the environmental conservation of the Ribeirão do Feijão Watershed (RFW) in the municipality of São Carlos during its period of validity (2006 to 2016) the link between human activities, the local social context, land use change and the effects of these dynamics on the conservation of the environment, thus providing a basis for the sustainable use and management of the environmental resources of São Carlos (SC) and other regions. Interviews with local residents and specialists, raised the social representations (SR) attributed to RFW analyzing what SR can express about the thoughts and relationships that individuals maintain with the organs with the state and with environmental laws. These expressions gave meaning to the perception of the local population about the state of conservation of the vegetation of the surroundings of where they live. The verification of the effectiveness of the APRW Law and its influence on the conservation of the RFW-SC was facilitated by geographic information systems tools that obtained data from the years of 2006, 2011 and 2016 comparing this data among themselves and also with neighboring municipalities (Itirapina and Analândia) that are also part of the RFW under the influence of the law APRW. There was a difference between the SR of the local residents, focused mainly on their productive and subsistence activities, and SR of the specialists, focused on urban supply. These differences in SR on the RFW generate conflicts since the specialists are also responsible for drafting environmental laws in the RFW that the local residents are subject to. The SRs raised by the interviews with the local residents of the RFW demanded new analyzes on SR, highlighting the most impactful to the environment (more impactful social representations - MISR) and the less impactful social representations (LISR). The MISR are related to subsistence, supplies and domestic use, while LISR refer to RFW as an affective site, linked to the following approaches: 1) well-being and admiration, 2) environmental dynamics and 3) water is life. Regarding the analyzes of the land use and cover data, it can be observed that in the period between 2006 (still without the influence of the APRW law) and 2016, that the forest areas in the RFW-SC increased by 36.89% (from 25.94% of the area to 35.51%). In the part of RFW-Itirapina / Analândia, forest vegetation increased from 16.02% to 18.83%, a relative increase of 17.54%.Regarding the permanent preservation areas (PPAs) in the RFW-SC under the jurisdiction of the APRW law, it was found that in the same period, the areas of PPAs had an increase of 16.42%, and in the RFW Itirapina / Analândia an increase of 11.1%. The environmental perception regarding the conservation status of the forest was consistent with the results of the survey, in which 53.85% of the interviewed residents believed that the forest vegetation is increasing, 26.92% said that it remained stable and 19.23% believed that the vegetation is decreasing. Regarding the importance of the inspection bodies, 69% of the interviewed local residents believe that they are important for environmental conservation, 23% for guidance and environmental education, and 8% have shown repulsion to these bodies. As for the knowledge of the APRW law by the residents, none of the interviewees seemed to know it; just have some knowledge regarding protection of APPs and cutting of trees in general.

Among the environmental programs implemented in regions potentially impacted by oil activity is the Beach Monitoring Program (PMP). Its objective is to evaluate the possible impacts caused by the exploration, production and out flow of oil and gas in marine tetrapods (birds, turtles and mammals), through stranding monitoring, rescue and rehabilitation of these animals. The objective of the research was to study the Beach Monitoring Project as a subsidy in coastal management, with emphasis on areas where there are Protected Areas (PAs). Therefore, the research was based on two case studies: the Beach Monitoring Program of the Campos and Espírito Santo basins (PMP BC-ES) which occurs on the northern coast of Espírito Santo and the Beach Monitoring Program of Santos Basin phase 1 (PMP-BS Fase 1), on the southern coast of the state of São Paulo, both are held due to the activities of PETROBRAS. Documentary research and semi-structured interviews were carried out, with the purpose of knowing the implementation, planning and execution of PMPs, as well as raising the involvement of the main social actors in this process. The main results obtained were the contributions in knowledge about the coastal and marine environment generated by the PMP data, as well as the impacts of human activities in this environment. In addition, direct and indirect contributions were made to the use of PMP data in the planning and management of PAs, such as assistance in the monitoring of the territory due to the daily activities of the field teams, technical basis for the creation of new PAs and use of data to integrate the Management Plans. However, for such contributions to occur issues related to data accessibility failures should be addressed and participation of society in general, as well as the different actors involved in the management of these areas, should be encouraged.

Riparian forests play a very important role in protecting watercourses and represent an energy source for the aquatic communities in low-order streams. Therefore, the input of allochthonous material from these ecosystems influence the food chains and create microhabitats that influence the composition and spatial distribution of aquatic macroinvertebrates. These organisms, in turn, are responsible for incorporating plant material into the secondary production and for decomposing the organic matter. Therefore, restoration of riparian vegetation, although frequently performed at a small spatial scale, may have positive effects on aquatic biota. This study evaluated the effects of riparian forests under restoration on the structure of aquatic macroinvertebrate communities and on the rates of organic matter decomposition in low-order streams in southeastern Brazil. Three types of streams were compared, 1) with natural riparian forest, 2) with riparian forest under restoration, and 3) with riparian zones altered by anthropic activities. Within each stream, a 150 m reach was selected to study the substrate characteristics of the streambed (small spatial scale), riparian forest (intermediate scale) and land use and occupation of the basin (large scale). Streams under restoration were intermediate between the agricultural and natural streams in relation to the composition of aquatic macroinvertebrates, showing that riparian forests under restoration have positive effects on the diversity of aquatic communities. Although restoration did not have a positive effect on organic matter decomposition rates, current velocity had a significant effect, being higher in the agricultural streams, suggesting that other factors at different spatial scales, modulated by the proportion land cover by riparian forests, can influence this ecosystem function through complex interactions.

The storage of digital objects in Cloud Services has increasingly been adopted to contain technological obsolescence and preserve digital information. However, more traditional Cloud Services do not yet have a framework that encompasses the applications of digital preservation in the life cycle of digital objects, nor do they support preservation metadata standards in their environments. In this sense, this research seeks to perform a study of the interconnection characteristics of the digital preservation metadata with Cloud Services. Through the Systematic Review of Literature, the mapping of the publications in the areas of Information Science and Computer Science that related the digital preservation metadata in Cloud Services was done. The data obtained in the retrieved documents were analyzed with the adoption of content analysis, highlighting as results the identified categories: terminological conceptualization of Cloud Services; digital preservation metadata adopted and employed in Cloud Services; research trends on the subject. It was possible to highlight the characteristics, functionalities and the relationship between digital preservation metadata standards and Cloud Services. It is concluded that the preservation metadata studies in Cloud Services are still inexpressive in the area of Information Science in the current scenario, both internationally and nationally. The need for a greater positioning of Information Science in the landscape of digital preservation metadata in Cloud Services is emerging, since this science holds the corpus of knowledge to answer the questions of storage, description, representation, and preservation of data and information in digital environments contributing to science and innovation.

The period placed between the early 2000s and the mid 2010s set up new experiences on the horizon of Latin America that presented themselves as alternatives to the neoliberal hegemony that followed the processes of democratic reconstruction of the 1980s and 1990s. Respected the peculiarities and specificities of each case, those experiences were broadly defined as different expressions of a post neoliberal State. This work aims to analyze the patterns of rupture and continuity represented by the post neoliberal experiences of Brazil and Argentina, considering as the object what became the main state strategy to fight social asymmetries in the late twentieth century: the Conditioned Cash Transfer Programs, respectively the Programa Bolsa Família and the Asignación Universal por Hijo.

The purpose of this paper was to investigate the potentialities and limitations of a teaching intervention, structured on the basis of making materials to be handled by visually impaired students, aiming at the construction of Pythagorean Theorem concept, systematization and learning. The chosen theme is part of Geometry field which has strong association with visual experiences, and from the hypothesis that this public is able to appropriate notions related to this concept as well as the sighted, providing their access by other senses, considering their specificities and adaptations. This study proposed to answer the question: "What are the potentialities and limitations of a structured teaching intervention from tactile materials related to Pythagorean Theorem, for the first grade students with visual impairment?" And to answer it, a qualitative research was carried out through a case study, with two congenital blind pupils of public schools in Itapevi and Barueri, both in São Paulo. The students passed by the interventions which consisted on the application of seven activities using a representative depictions of polygons and specific instruments to measure and compare angles. The theoretical basis of this research was the study of Vygotsky's conceptions of the development of higher psychological functions through the observation of information transit (the thoughts) at the zone of proximal development of an individual. An overview of Brazilian legislation on inclusive education that theoretically approaches disabled people education, especially visual sensory, was also part of the elements that underpinned this study. The results showed that a mediation action of an experienced person aided with the manipulation of materials and structured activities within each students specificities, made possible the acquisition and development of knowledge related to Geometry by the students, to construct the concept of the Pythagorean Theorem. The curricular adaptation has contributed to an inclusion in which teaching and learning process prevails.

Brazil still faces very serious problems currently related to the management of solid waste in various sectors. Among the most diverse waste generated daily, sewage sludge deserves special mention due to its problematic and often neglected final disposition. The great concern resulting from the inadequate management of this type of waste lies in the fact that it is a contaminant due to the presence of pathogenic microorganisms and toxic metals that are harmful to human health and the environment. However, as an alternative, commonly between treatments and final provisions, what is more evident is the reduction of volume and humidity for disposal in landfills. At present there is no denying certain prerogatives that meet this type of possibility, such as the scarcity of areas suitable for the construction of landfills and the guidelines related to the integrated management and solid waste management governed by Law No. 12,305 / 10, regulated by Decree No. 7.404 / 10, of December 23, 2010, which establishes the National Solid Waste Policy (PNRS). Thus, the biooxidation of sanitary sewage sludge by means of the composting process can improve the physical, chemical and biological qualities of the waste, as well as represent a promising alternative to soil conditioning chemical compounds. In this sense, this study presents results of the composting process of sanitary sewage sludge generated in UASB reactors through the use of commercial inoculum. The objective of this study was to evaluate the efficiency of the commercial inoculum in the composting process. During the composting process, analyzes of temperature, humidity, pH, electrical conductivity and solids contents (total, fixed and volatile) were performed, as well as the agronomic parameters of the organic compounds obtained in the final composting process. In view of the above, the results of the analyzes carried out during the composting process did not show significant improvements that justify the use of the commercial inoculum when compared to the results obtained in the composting process that did not use the commercial inoculum. Likewise, the evaluation of the analyzes performed on the organic compounds obtained at the end of the composting processes (inoculated and conventional), did not present significant changes that justify the use of the commercial inoculum. Thus, in view of the procedures in which the study was developed and considering the type of sanitary sewage sludge and the structural material used, the use of commercial inoculum in the composting process did not provide significant improvements to the point of justifying its use, with the microorganisms being native present in the system sufficient for the degradation process of organic matter.

In a context where the most informations stored by the organizations is in the text format, the development of computer tools for knowledge discovery aimed to organization and information retrieval is a task that holds attention and relevance. The extraction topic models are often employed in this task. This models are able to establish relations between documents and found latents patterns in sets of them. However, there is an additional challenge for documents composed by multiples subjects. For texts with subject shifts, it is necessary, in fist, found the chunks of texts that address a single subject. So, the text segmentation techniques are used to break a text in segments with a relatively independent issue. The combination of the text segmentation and topic extraction algorithms, can be used to make an structure that helps to understanding textual data, which are inherently non structured. The creation of an topic organized structure, that incorporates latent information concerning the corpus, favors Information Retrievals techniques. This approach allows query expansion space, besides the original set of terms of each segment, and the identification most relevant pieces of text. This work presents an methodology to connect the Text Segmentation techniques to the Topic extraction models, in order to generates an derivative structure from a non structured corpus, which concentrates the original texts plus the latent informations and organized by semantic likeness. The research for this thesis investigates the text segmentation techniques and the Topic extraction models to develop an Information Retrieval system for meeting minutes. We develops an system to give to the user the most relevant segments to the query. The segmentos presented are clustered by this topics, that also enables exploratory searches to the data base, through browsing by groups of semantically related segments. Furthermore, less relevant segments are omitted, allowing results focused on the researched subject. Five techniques of text segmentation and three Topic extraction models from the literature was evaluated. Based on the set of meeting minutes analysed, we create an manually annotated corpus with informations on the thematic composition of the meeting minutes and about the issue shifts. The annotated corpus served as reference to objective evaluation of the text segmentation techniques. We also evaluate the results obtained with the Topic extraction models. This results were analysed by related to the meeting minutes context. The results points the employed techniques and the methodology presented gives satisfactory answers. However, more data can be necessary to leads new experiments in order to improve the used techniques. The system implementation and the tools used in the work, as well the results obtained in the evaluations, plus the annotated corpus are the principal contributions of this work, in order to support next works.

Product miniaturization is a current trend, involving several industry segments. Microforming is an especially interesting process to produce parts in millimeter scale because of its high productivity. The grain size can be considered as a key micro structural factor for downsizing the deformation process because it affects almost all physical and mechanical behavior of polycrystalline metals. Ultrafine grain material shows a great potential for microforming since they can decrease the elastic and plastic anisotropy that would prevail in a coarse grain structure. The aim of the study is to compare the conformability of coarse and ultrafine grain structures of a commercial grade aluminum (ASTM AA1050) in the deep drawing process at different scales to ckeck the increase in the quality of the miniaturized product and process. The material, originated from a 7 mm roll-casted sheet, was solutionized at 400°C for 2h producing a coarse grain structure of an average grain size of 150µm (CG material). The production of ultrafine grain samples was carried out by Equal-channel angular pressing (ECAP) using a die with an internal angle of 120°C, and route A (no rotation of the samples between passes) up to 8 passes, achieving an average grain size of 1,5µm (FG material). The grain size effect was analyzed by microhardness and tensile tests. In order to get an effective comparison between differences in dimensional scales and grain sizes, the scalar comparison was performed in four effective volumes: 252mm3, 42mm3, 28mm3 and 1mm3 in tensile experiments performed at a strain rate of 10−3 s −1. The traction test was also performed by the virtual field method (VFM), to verify the behavior of the material in the of the in the necking region. The deformation pattern was characterized by electron backscatter diffraction (EBSD) and microhardness tests and scanning electron microscopy. A drawing die was designed to evaluate the behavior of these two materials with sheet thickness of 1 and 0.5 mm. The two materials had different deformation mechanisms: in CG the strain concentrated inside the grains and new interfaces were created with continuous hardening in the neck region, whereas in FG the thickness of the existent boundaries increased and strain was promoted by grain boundary sliding, which yield softening in the neck region. The CG structure yield larger uniform elongation and deeper drawing rate than the FG structure. On the other hand, the form adjustment and strain distribution was more uniform in the FG material than in the CG material. Contrary to the expected from the literature review, an increase of the deformation stress was measured when the scale of the sample was reduced. This effect was more accentuated in the FG than in the CG material, and this behavioral was associated to the increment of the relative sample volume participating in the stress concentration at the reduced scale.

This work presents a methodologic approach to map urbanistic and environmental conflicts using data collection of legal records from 2006 until 2016, in São Carlos region, State of São Paulo. The metodology consists in: literature review, quantitative analysis, characterization and mapping. The literature review sought to group information as possible about the search objects. The data were obtained by analising two types of documented legal instruments (Public Civil Lawsuits and Terms of Conduct Adjustment in Federal and State Justice) that aim to protect public interests. The methodology consisted in collecting data of lawsuits which made possible a quantitative analysis, characterization and mapping forementioned conflicts. For each oft he two legal instruments a database has been created in order to analyze the object of study in terms of duration, nature, defendants and authors. The characterization was carried out by analyzing the obligations for each lawsuit and the creation of subjects and categories, that allowed to identify the main lines of conflict. The mapping was realized by Google Earth Pro software, using geographical location data found in the analyzed documents. These data were subsequently imported into a Geographical Information System, which enabled the creation database statistc analyses of spacial data. The used software was (ESRI ArcGIS, version 10.3). Thus, it was possible to carry out data storage and processing, as well as the documentation of geographic information and mapping of environmental and urban conflicts. Databases allow you to conduct further for future research.

This dissertation intends to reflect on some points of the reconstructive analysis of law and democracy in the perspective of Habermas' discourse theory, in order to discuss the possibility of an emancipatory social integration inscribed in modern society. Starting from the communicative rationality, the public sphere category and the tension between facticity and validity, present in different forms and at various moments in the work Between Facts and Norms, our work reflects on the communicative potentials inserted in modern institutions. Positive law, in the tense relation of distinct and complementary to morality, is the "transforming" element that allows us to move both in the world of life and in the system, allowing us, within the democratic process, to think about the elaboration and implementation of the association of free and equal citizens. The procedural model of democracy proposed by Habermas, understood as a dynamic process, devoid of content, will constitute the point of balance between the demands of communicative action, filtered by the public sphere, and the decision-making processes of the political system. In this sense, our work, in view of emancipation, discusses the emergence of a radical reflection on the legitimacy of law and democracy as fundamental categories of social integration facing the challenges of complex capitalist and pluralistic modernity.

The danger to aviation safety due to birds has drawn attention for many years. In Brazil, more than 8,000 wildlife collisions were recorded between 2011 and 2015, in addition to a significant increase in wildlife sightings at airports or their immediate surroundings. This increase may be due to the fact that aerodromes are naturally attractive to the fauna, especially birds, because they are large open areas, protected from predators and humans, and have water and food sources for many species. The management of bird risk, in order to be efficient, must rely on local actions of data collection and observation of the attractive fauna-problem factors such as the black-headed vulture (Coragyps atratus), widely distributed throughout Brazil. Thus, the present study aimed to understand the use of the airport space by the C. atratus species, as well as the attraction factors that keep it frequently present inside the SBJD airport site and propose management measures aiming to reduce the potential risk of collisions. For this purpose, the species was monitored for 14 months to identify the most critical points. The analysis, through Kernel Maps, indicated that having restaurants inside the airport site interferes with the presence density of the species, and its higher frequency in the rainy/hot period. A Fauna Risk Management Program was also developed with the objective of managing the risk of collision between animals and aircraft operating at and around the aerodrome, through procedures and operational routines.

The so-called Representation Languages have always been directly related to the instruments and professional practices identified in the field of Information Science. From the development of digital technologies, the bibliographic representation formats have evolved to meet emerging information demands. In this sense, the methods of representation have always been objects of investigation in the field of Information Science that since its creation, develops methods directed to the representation of the diverse types of informational resources. In view of this scenario, we ask: what are the relations between the representation languages conventionally used in the area of Information Science and the technologies of interconnected data publishing? The objective of the research is to analyze the evolution of representation languages and to identify the existing relationships between the representation tools used in the area of Information Science and the new trends of interconnected data publication. It is a theoretical research of qualitative approach, and applied nature, focused on the analytical observation of the documents that approach the thematic of information representation. Bibliographic and documentary analysis is used as methodological procedures, addressing the volume of data and information obtained through the technique of content analysis. The research is justified due to the need for studies that corroborate for a better understanding of the new models of representation based on the proposal of interconnected data and its applications for the area of Information Science. As a result, an overview of the evolution of representation languages is presented and the main relationships with the new interrelated data publishing trends are described, especially the BIBFRAME data model.

The semi-terrestrial crab, Ocypode quadrata (Fabricius, 1787), popularly known as ghost crab in the world and maria-farinha in Brazil, is the most conspicuous invertebrate on sandy beaches of the western Atlantic coast. The species is extremely relevant to this ecosystem, since it´s the top-chain predator concerning to other invertebrates. However, the study about biology of this crab still exhibition a shortage of information. Therefore, the objective of this work was to evaluate the diet and population dynamics of O. quadrata in three morphodynamic beaches in southern coast of Brazil. The collections were carried out on March 2017 to February 2018, on the beaches of Lagoa de Barra Velha, Navegantes and Brava, located in coast of northern Santa Catarina. A total of 698 specimens were captured: 55.58% males, 33.52% females, 1.86% ovigerous females and 10.90% juveniles. Among these, 660 stomachs were examined and the food categories were expressed by the food index (IAi). The crab diet did not show significant differences regarding sex, ontogeny and beaches with different morphotypes. There was only variation in relation to the year, with the most representative categories being Insecta, Unidentified organic matter and Crustacea. The O. quadrata crab was classified as opportunistic with a carnivorous food habit, with a trend to insectivory. Regarding the population aspects, the densities of burrows showed no differences during the year and between the environments, and the pattern distribution of burrows was aggregated for the three beaches. Regarding sex ratio, there was a deviation in favor males at some periods in the year for the three sites. The recruiting period occurred in late summer in Navegantes and in the cold season in Barra Velha and Itajaí. Sexual dimorphism was evident for this species, males tended to invest more in body mass than females, but both presented positive allometric growth. There was also a difference in growth between the beaches of Itajaí and Navegantes. Von Bertalanffy's growth model demonstrated that the highest value L∞ (maximum width) estimated for both sexes was in the reflective beach (Barra Velha). The maximum longevity of the species was Tmax = 4.86 years for males and Tmax = 3.61 years for females. Regarding sexual maturity, the size of first gonadal maturation (L50) for the species resulted in differences between the sexes, with males ranging from 2.40 cm to 2.83 cm and females between 2.84 cm to 3.01 cm.

This ressearch intents to analyse, based on ethnographic study made in Praça Franklin Roosevelt, a public square in the neighborhood of Consolação (Central region of São Paulo), interfaces between determined mechanisms of space management and their concrete appropriation, destabilization and resistences. Builded in 1970, in the middle of the brazilian military dictatorship, the square was completely rebuilded in the year 2010, by the cost of R$ 55 million. Among the intentions behind such intervention, there were an attempt to estabilish a higher state control of the uses of that space, considered as problematic from a urban planning point of view. But, despite the intense presence and transit of police forces in the space since the reconstruction, not only certain modalities of insurgent uses still occupy it but also many of them assume directly critical positions on that repressive management of the uses of public spaces. The focus on this ressearch is to think apropriations, questionings, ruptures, in an experience level, of political discourses and institutional mechanisms that act in the establishment of a restrictive and reppressive management.

This ethnography is about the produce of images and senses in the world on nanometric scales in a scientific and technological laboratory. Images that come to life and senses and transformed in artistic artifacts. The Nanoart, imaginative creations that have their root in the images of electronic microscopes, are not merely the matter of study of this work, they also help me as ethnographic guides into my immerging and learning what is going on in a nanotechnology laboratory, named LIEC. The nanoworld, the world occurring in the depths of matter and inhabited by vibrations and atomic particles are explored there, in the dual meaning of this word. Molecules and atoms are embedded by researches in a repeated search for management of the forms and associations of chemical compounds manipulated by the wish of their “masters. Scientific images that are generated by microscopes and spread as visible evidence of a characteristic of the material produced. The later generated arts are a small fraction of these scientific images chosen to become artistic artifacts. They are inserted internal and external to the scientific world into circulation, included into contexts of scientific popularization and disperse in the social environment, acting as elements of perception capture in favor of the worlds on nanoscale, this world that is in a daily interaction with researchers and laboratory technicians.

The shrimp trawling is carried out all over the Brazilian coast and has a significant economic, social and cultural importance. This type of fishing is recognized by the impacts that they cause on the substrate and benthic fauna, being effective for the target species, but not selective for the others species, considering that most of them are caught "unintentionally". In this work, the trawls of three traditional fishing areas of the Santa Catarina coast were analyzed from different perspectives, leading to the elaboration of four chapters. The first chapter deals with the environmental and ecological evaluation of the invertebrate species that occur in these places, the relationships with the environmental variables and possible impacts in the trawling areas. In the second chapter, under the same perspective of the first, the ichthyofauna of these sites was analyzed to evaluate its response to environmental conditions. The third chapter presents a conservationist approach, where the fish and invertebrate communities were evaluated in order to identify the best strategy for conservation, considering the dissimilarities and the organization of the species among the sites. Finally, the fourth chapter provides biological information on the main fish species from the central locality of our studies (Penha-SC). Considering the three studies, we conclude that: (1) - the areas are under frequent disturbances; (2) - Barra do Sul has a homogeneous substrate, predominantly sandy, which causes negative effects in the fish and invertebrates communities, (3) - Porto Belo has the highest diversity of species and the best quality of habitats, while Penha is in an intermediate situation between the studied environments; and (4) - three environments are different and have a high conservation value, particularly for high turnover of species. Therefore, these areas need prioritization for regional conservation. Stimulating future bycatch experiences for biota knowledge is necessary, since most of the marine invertebrate and fish species captured in this study lack behavioral, biological, and ecological information. Thus, to know more about the dynamics of the populations affected in this and in the other trawling areas of the Brazilian coast is of extreme importance to manage and contribute with the conservation of the species, aiming the sustainability of the fisheries.

Understanding the processes that create the patterns of species composition and biodiversity variation across the space has been one of the main topics within the theory of metacommunities. However, most studies rely on static snapshots of community data and few studies have examined the importance of including temporal variability. Here, we examined beta diversity distribution of anuran community composition through three years and considering the whole period of study at different spatial extents in the Brazilian Atlantic Forest: i) seven inland communities; ii) seven coastal communities; and iii) communities pooled together. We partitioned total beta diversity into species replacement and nestedness-resultant components then we used deviance partitioning to explore the relative importance of environmental and spatial factors explaining the distribution of anuran community changes over the years. Species replacement was the predominant component of anuran beta diversity, but average values of species replacement and nestedness-resultant were not congruent across the years. We observed that average values of beta diversity components decrease when species composition of whole period of study are pooled together and increase with increasing spatial extent. Furthermore, our results indicate that Brazilian Atlantic Forest anuran community compositions are highly dynamic in space and time, and the factors explaining the distribution of species replacement and nestedness-resultant are dependent of the sampling year and spatial extent. Thus, metacommunity studies that do not evaluate different spatial and temporal changes should be cautious about the generality of their biological conclusions.
Demarcando vestígios: definindo (o território de) indígenas em isolamento voluntário na Terra Indígena Massaco

The presence of reports in the big mass media spreading the existence of isolated indigenous people in the Amazon forest has grown exponentially over the last years. Such movement is associated mainly due to the onslaughts of a “developmental” nature that is moving forward to lands that are most wanted from the predatory capitalism, along with persistent illegal activities looking for timber and other resources from the forest. Yet, Brazil is a reference when it comes to protection measures to such indigenous communities, and this reputation is due mostly to policies related to demarcation of lands, highlighting the demarcation of an indigenous area exclusively to isolated people in 1996: the indigenous land called Massaco, in the state of Rondônia. In order to enable the land demarcation, it was necessary to create innovations regarding demarcation procedures, in which, as a matter of course, must host the attendance of the indigenous themselves when defining their traditional territory. Regarding the Massaco’s area, it was by the track and traces from an indigenous group that their territory and existence have been defined, while their image is still being designed as an ongoing study of the artifacts found, forsaken Camps, appearance reports and distance observations: they cannot be heard, obviously, therefore they cannot define “their” own territory. The aim of this research is to explore the debates related to the identification of such groups in order to, subsequently, investigate how the land demarcation took place, as well as seeking the knowledge of how their image remains continuously under negotiation at the politics scope for the isolated indigenous people from Rondônia and the Brazilian Amazon.
