Item Dinâmica de competição agropecuária pelo uso do solo e implicações para a sustentabilidade dos recursos hídricos e remanescentes florestais(Universidade Federal de Goiás, 2012-09-21) Abdala, Klaus de Oliveira; Lee, Francis; http://lattes.cnpq.br/1763392088652134; Ribeiro, Francis Lee; Ferreira Júnior, Laerte Guimarães; Miziara, Fausto; Oliveira, Gilca Garcia de; Nogueira, Jorge MadeiraAccording to the IBGE is possible to identify four main complexes: cattle, soybeans, corn and sugar cane, responsible for the use and occupancy of approximately 97% of the soils. This thesis presents a survey of impacts on consumptive use of water resources, soils and forest remnants, from the dynamics of land use and specialization of municipalities in the state of Goiás in the complexes: Cane sugar, soybeans, corn and cattle.The results confirmed the hypothesis worked and indicated that municipal specialization in these complexes is the result of the comparative advantages of regions and that this specialization locate geographically environmental impacts analyzed.Therefore, working with the hypothesis that this specialization is the result of the exploitation of municipalities comparative advantages by competitive advantages of complexes in question.In response to questions for investigation, it was possible to identify the comparative advantages of the municipalities and the main competitive advantage of the complexes. In addition, indicators were generated from environmental risks to agriculture and a location model of these complexes as a function of the comparative advantages of the municipalities, which constitute subsidies to the establishment of institutions and public policies for regional development, the economic ecological and agro-ecological zoning and coordination between agricultural and environmental policies.Item Educação ambiental e meio ambiente no contexto de Palmas Capital Ecológica(Universidade Federal de Goiás, 2010-06-14) AIRES, Berenice Feitosa da Costa; BASTOS, Rogério Pereira; http://lattes.cnpq.br/6015137404238990Analyze the representations of the Environment and Environmental Education of teachers and students of basic education Palmas (TO) was the main goal of our investigat ion. The focus of research is centered on representations because we think they reveal the world of the subject and open spaces both for reflection and for action. Through literature review and rescued some forms of environmental education has been practiced and how the environment has been conceived, trying to show how the place and everyday relationships are constructive representations and relevance to the development of formal education, especially by experiments that occurs at the local level, but are not disconnected from global experiences. Thus, the study focuses on the pedagogical practices of teachers in the EA of private education, city and state and graphical representations of students in elementary and secondary education about the environment. For the realization of this theoretical research using sources from different areas of knowledge and empirical research, using the analysis of questionnaires, documents, maps, observations, records, photographs and statistical analysis (Chi-square and Fischer's exact test). From the data collected, the practice of EA was revealed as a variety of representations of students and teachers about the environment. The results offer a view as has been the practice in environmental education in the area surveyed, mainly in relation to the activities of EA developed in basic education. From the elaborate framework of representations and pedagogical practices found and the end of the investigation, it was possible to formulate some guidelines for programs of continuing education of teachers in EA, and some principles for the construction of meaningful practice of EA considering the context of basic education Palmas (TO). It is emphasized that the importance of this research area is to contribute to the reflection on the values that can permeate the environmental education and also by providing assistance, not just getting in dealing conceptual.Item Diversidade e vulnerabilidade de insetos aquáticos em paisagens produtivas(Universidade Federal de Goiás, 2014-05-30) Almeida, Mirian Cristina de; Marco Junior, Paulo de; http://lattes.cnpq.br/2767494720646648Loss and habitat fragmentation at the landscape scale, the land use and local integrity of habitats (e.g. riparian forests), associated with the social structure of rural lands are factors that can determine the loss of species. These could be greater where of landscapes is homogenized by the same type of land use, such as in agricultural areas. This has important consequences and could be determine that Conservation Biology practices are not based only on Protected Areas. These approaches applied to aquatic insects occurring in Cerrado of Goiás state show that endangered species of Odonata, distributed in the central and south region presented a historical habitat loss of 76%. Regional assessment according to the criteria of the IUCN, a total of 34.8% of species would be in some category of threat, these 71.5% were Critically Endangered, 22,8% Endangered and 4.9% would be vulnerable. Local environmental variables, spatial structure of habitat and matrix in buffers of 250 meters and habitat spatial structure and matrix in the landscapes of 25 by 25 kilometers explained the local richness of Odonata adults in streams. Richness decreases with increase in pasture in the 250 meters buffers and crop in the landscape and increases with the opening canopy. For Ephemeroptera, Plecoptera and Trichoptera (EPT) immature, richness increases with increasing riparian forest 250 meters buffers, with the opening of canopy and the average conductivity of the water. When we consider the habitat integrity (riparian) associated with the structure of rural property around protected areas, the integrity of riparian vegetation as measured by NDVI was lower in the Buffer Zone of sustainable protect areas associated with small farms. The area of the property dedicated to the cultivation and cattle size has direct impacts to lower NDVI values.Item Morfometria e uso da terra da bacia hidrográfica do Rio do Coco e suas implicações sobre a produção e transporte de sedimentos(Universidade Federal de Goiás, 2017-03-31) Almeida, Rejane Freitas Benevides; Bayer, Maximiliano; http://lattes.cnpq.br/4552593148328465; Ferreira Júnior, Laerte Guimarães; http://lattes.cnpq.br/8647270006257055; Ferreira, Nilson Clementino; Faria, Karla Maria Silva de; Zancopé, Márcio Henrique de Campos; Silva Júnior, José Luiz CabralThis study aimed to evaluate the influence of morphometric aspects and land use in the areas of permanent preservation of watercourses on the production and transport of sediments in the Rio do Coco watershed. It is located on the right bank of the Araguaia River basin, in the state of Tocantins, between the municipalities of Caseara, Marianópolis do Tocantins, Divinópolis do Tocantins, Monte Santo, Paraíso do Tocantins, Chapada de Areia, Pium and Barrolândia. The first phase of the study consisted of compartmentalization and morphometric analysis of the basin, where it was verified the existence of regions (high basin) with natural characteristics indicative of greater susceptibilities that may potentiate sediment supply, pointing out the need of more effective planning of the use activities. The second phase was dedicated to evaluating the cover and the soil use of the Rio do Coco basin, in addition to identifying and quantifying the percentage of areas with land use conflicts in the areas of permanent preservation of water courses. For this purpose, the mapping of land cover and land use was carried out using images from Landsat 8 (2015) satellite. For the identification of PPAs buffers with buffer strips were created according to the limits defined in the legislation. The conflicts of land use in APP were measured after the overlap of the map generated in the classification and the PPA map, being verified for the entire basin 32.8% of areas with conflicts of use along the bodies of water and, although the sub-basins belonging to the region of the high basin are the regions with greater irregularities. The third and last phase of the thesis evaluated the production and transport of sediments in the Rio do Coco basin and its most representative sub-basins. This analysis was carried out by means of measurements of liquid and solid discharges in the Coco River and in the mouth of the channels of the main sub-basins. Measurements were initiated in November 2014 extending through April 2016 from bimonthly collections. The quantification of the solids load obeyed the methodology defined by Carvalho (2000b), and the flow measurements are performed using the following flow meters: ADV (Acoustic Doppler Velocimeter) FlowTracker and ADCP (Acoustic Doppler Current Profiler). The total discharge followed the method of Colby (1957) in Carvalho (2000a) and the specific production of sediments was analyzed based on the methodology of Carvalho (2008). From these analyzes it was possible to measure the volume of material transported by the main drainage channels of the basin, being proved that the region of the high basin is responsible for most of the sediments produced and transported in the water bodies. It should be noted, therefore, that this material has not arrived fully in the Araguaia River, part is being deposited along the canal, it is evident that in the basin there is an environment where production and transportation predominate and in another the accumulation. The results found in this phase of the research only reinforce the evidence observed in previous phases, where it was verified that the morphometric aspects are determinant in the sedimentological discharge of the basin, being the use and coverage of the soil considered maximizer of the whole process.Item Análise da Sustentabilidade Ambiental em Estabelecimentos Agrícolas em Goiás(Universidade Federal de Goiás, 2010-06-18) ALVES, Luiz Batista; MIZIARA, Fausto; http://lattes.cnpq.br/3275079358565458; BASTOS, Rogério Pereira; http://lattes.cnpq.br/6015137404238990In this work are presented and discussed other forms of studies related to analysis of environmental sustainability with the use of methods that permit the human environment to demonstrate its environmental impacts on rural properties in the town of Silvânia, State of Goiás. The choice of the municipality of Silvânia occurred because of present permanent preservation areas susceptible to exploitation by various activities in the city, allowing checking the environmental sustainability in land reform settlements in comparison with other rural property. The Project for Sustainable Development (PDS), established in 1999 comes meet the new brazilian environmental laws, seeking the durability and perpetuity of the settlements (family farm) in order to provide less environmental impact. On the other hand, has been observed that in large farms (agricultural employer) occurs deforestation to expand the area explored, giving rise to a particular crop, in seeking increases in production. Studies have shown the link between deforestation and biodiversity conservation consequences that hinder sustainable development. Still, the methodology of the indices applied to the settlement of São Sebastião da Garganta and João de Deus, the results showed considerable levels of sustainability. Analyzing the settlements in comparison with the Farm Silvânia through satellite images, it appears that the agrarian reform, there were minor differences of deforestation between periods and a greater difference occurred in the Farm Silvânia as favoring extensive livestock farming. But we can not say that the settlements have a higher level of environmental sustainability, where by means of observation of annual averages, there are almost identical proportions of deforestation, and that the settlements, deforestation occurred in a more fragmented than in Farm Silvânia and may cause a greater reduction of species in the environment, reducing the potential for environmental sustainability. Finally, the results may serve as guidance in formulating environmental policy to keep families in agrarian reform settlements, contributing to sustainable development of rural properties in the region, coupled with supervision to allow continuity in the production process in a sustainable manner.Item Capacidade de interceptação pelas árvores e suas influências no escoamento superficial urbano(Universidade Federal de Goiás, 2015-04-16) Alves, Patrícia Layne; Formiga, Klebber Teodomiro Martins; http://lattes.cnpq.br/0787413754235970; Alves, Patrícia Layne; Barbassa, Ademir PaceliProblems related to water, in the urban environment, have drawn attention in the face of the problem caused by its lack and/or excess. Among this backdrop there is the tumultuous occupation of urban space that combined with the suppression of soil coverage and vegetation leads to the urban runoff higher volume, pollution and shorter time to peak discharge. In this context, the benefits of urban afforestation are present, which besides the aesthetic value added to space, set up physical barriers to stormwater, favoring its retention, storage and infiltration into the soil. This study aims to evaluate the capacity of rainfall interception treetops the some species, reduce the volume of urban runoff, slow the flow peaks, as well as to expand the attention span of an urban watershed. The research was field experiments with recurrent arboreal species in the urban afforestation of Uruaçu, Goiás, using pluviographs, trunk collectors and water level sensor. From the use of interception parameters determined in this study, computer simulations using the Storm Water Management Model Model (SWMM) were performed, starting from the proposition of scenarios with different types of territorial installment associated with the Low Impact Development practices (LID) and urban forestry. During the data collection period 2012/2013, the rainfall events had a median of accumulated rainfall of 16.7mm. During this period, the median values of interception were Mangifera indica - 8.0mm; Pachira aquatica - 7.4mm; Licania tomentosa - 7.2mm; and Caesalpinia peltophoroides - 4.8mm. The period of data collection relating to 2013/2014, the median precipitation of rainfall events were 20.7mm, and the median values for interception and stemflow were respectively: 5.7mm and 0.1mm for Mangifera indica; 4.5mm and 0.2mm for Licania tomentosa; and 3.8mm and 0.3mm for Tabebuia ochracea. The delay at the start of average rains caused by tree species was 3min. The presence of individual trees afforded a median delay in the peak time of 3 min, a reduction of the peak flow of 0.8 mm/min and runoff of 4.7mm/min. Through simulations with the scenario where the wooded urban planning aggregated all LID techniques employed in this study, it was possible to achieve a reduction in peak flows in 3.42m³ / s, compared to conventional design; allowing storage of a volume of water in 4470.59m³ local infiltration proposed structures; and delay the peak flows of up to 6 min. This thesis confirms the interference of the individual characteristics of the species in the rain interception capability by their canopies and reducing runoff, highlighting the need for careful definition of the species that make up the urban forestry; testifies the existence of variations in interceptions in relation to rainfall events and during their occurrence; as well as quantitative data points precipitate volume reduction and drained by the tree individual presence in urban areas. Their research shows that, alone, afforestation and LID techniques cause little reduction in volume and flow and little delay in time to peak flow, while combined contribute significantly to drainage. This study differs from the use of recording rain gauges and linígrados for the measurement of precipitation and runoff directly under the canopy of individual trees in an urban environment; and adds to SWMM the insertion of arboreal benefits in hydrological simulation.Item Caracterização citogenética de bovinos da raça Nelore (Bos taurus indicus, Linnaeus 1758)(Universidade Federal de Goiás, 2019-09-13) Amancio, Andréia Pires; Cruz, Aparecido Divino da; http://lattes.cnpq.br/7868817504129985; Cruz, Alex Silva da; Amaral, Alliny das Graças; Cruz, Aparecido Divino da; Silva, Claudio Carlos da; Brito, Cintia Pelegrineti Targueta de AzevedoThe agricultural sector has been standing out in the Brazilian economy in recent decades for significant increase in productivity and its growing importance for maintaining the country's balance of trade. After the introduction of cattle in Brazil and their subsequent dispersal throughout the national territory, there was an intense process of adaptation of certain groups to specific environmental conditions of each place or region, which is responsible for the formation of several local Brazilian cattle breeds. These animals may present numerical and/or structural chromosomal alterations, which may result in a group of undesired characteristics to the producer that intends to expand his herd or even for the preservation of characteristics of a species. The aim of this study was to standardize the C, GTG and NOR banding for the bovine subspecies (Bos taurus indicus, Linnaeus 1758) and subsequently produce a pancentromeric probe by amplification and labeling the centromeric regions of autosomal chromosomes of cattle. Bovine blood samples were collected to detect metaphasic chromosomes using the cell culture method. Subsequently, cytogenetic banding, amplification, chromosomal probe labeling and FISH technique were performed. Through the banding it was possible the correct chromosomal pairing of these animals and with the use of the pancentromeric probe, the marking of the centromere regions of all autosomal chromosomes. These results may offer a new tool that meets the needs of genetic improvement of these animals.Item Efeitos genotóxicos, mutagênicos e comportamentais de nanopartículas de dióxido de titânio em girinos de Dendropsophus minutus (Hylidae, Anura)(Universidade Federal de Goiás, 2021-08-20) Amaral, Diogo Ferreira do; Rocha, Thiago Lopes; http://lattes.cnpq.br/6325937100056775; Silva, Daniela de Melo e; http://lattes.cnpq.br/9895211901348365; Rocha, Thiago Lopes; Jacob, Raquel Fernanda Salla; Silva, Cláudio Carlos da; Nomura, Fausto; Formiga, Klebber Teodomiro MartinsNanomaterials (NMs) have been used in an increasing number of commercial products, and its rapid expansion could lead to their release into aquatic environments. The accelerated production of the various types of conventional products at nanoscale has been fundamental for the economic progress of several countries. Many types of nanoparticles and nanomaterials are already being used, and other varieties are expected to appear in the future. However, there is little knowledge about the impact of NMs on biota, especially on amphibians. Therefore, there is a need to better classify and understand NMs. The first part of our study has reviewed the historical use of amphibian species as model systems in nanoecotoxicological studies, which summarized data available in the scientific literature on the genotoxic, mutagenic, histopathological, embryotoxic, and reproductive effects of NMs in different groups of amphibians. The interaction, bioaccumulation, mode of action (MoA), and ecotoxicity of NMs in amphibians were also reviewed. The nanoecotoxicological studies were carried out with 12 species of amphibians, eight from the Anura order and three from the Caudata order. Xenopus laevis was the most studied species. Studies were conducted primarily with inorganic NMs (72%) compared to organic ones. Nanoecotoxicity depends on the behavior of the NM, the transformation in the environment, and the developmental stages of the amphibians. The MoA of NMs in amphibians was mainly associated with the production of reactive oxygen species (ROS), oxidative stress, genotoxic and mutagenic effects. The results emphasized the need for more studies that test the ecotoxicity of different NMs, concentrations, and exposure periods in environmentally relevant approaches. In addition, there is a need for standard protocols for nanoecotoxicological testing with amphibians. The reviewed data showed that amphibians are suitable organisms to assess the environmental impact of NMs and indicated essential gaps in research on the ecotoxicity of NMs in freshwater ecosystems, as well as recommendations for future research. In this sense, we observed from the first chapter that the most produced and consumed nanoparticles worldwide are titanium dioxide nanoparticles (TiO2 NPs); whose release into the environment are known to induce toxic effects in aquatic invertebrates and vertebrates. However, knowledge of its impact on neotropical amphibians remains limited. Thus, the second chapter of this thesis aimed to evaluate the toxicity of TiO2 NPs and its dissolved counterpart, titanium dioxide (TiO2), in a species of anuran neotropical amphibian (Dendropsophus minutus). DNA damage, biometric parameters, and behavioral changes were analyzed in tadpoles after exposure to three environmentally relevant concentrations (0.1, 1.0, and 10 mg L-1) of TiO2 and TiO2 NPs for 7 days. As a result, we verified DNA damage in D. minutus tadpoles exposed to both forms of Ti compared to the control group. We also identified a similar reduction in overall size, body length, width, and height of the tail musculature in tadpoles exposed to TiO2 and TiO2 NPs compared to unexposed tadpoles. Regarding the behavioral test, the tadpoles showed less mobility and were more distant from the conspecifics (less aggregated) when exposed to NPs. Therefore, the simultaneous use of multiple biomarkers was essential to assess the adverse effects of the nanomaterial and establish a reliable approach for biomonitoring of aquatic ecosystems. Our study increases the knowledge about the genotoxic, morphological, and behavioral effects of TiO2 and TiO2 NPs in anuran amphibians, contributing to future studies in the environmental risk assessment of nanomaterials.Item Caracterização biofísica e potencial à intensificação sustentável da pecuária brasileira em pastagens(Universidade Federal de Goiás, 2017-12-18) Arantes, Arielle Elias; Ferreira Junior, Laerte Guimarães; http://lattes.cnpq.br/8647270006257055; Silva, Elaine Barbosa da; Couto, Victor Rezende Moreira; Miziara, Fausto; Ferreira, Nilson Clementino; Ferreira, Laerte GuimarãesCattle ranching is the main land use activity in Brazil, with about 175 million hectares of cultivated pasture, with at least 50% of these being with some degree of degradation. Degraded pastures present low biomass production of little nutritional value, which leads to low animal weight gain in the rainy season and loss of weight in the dry season. Due to its low productive efficiency, if these areas were identified and recovered, they could be intensified, freeing pasture areas for other uses. In this context, the objective of this work was to evaluate the pasture vigor and the potential livestock intensification for Brazil. In order to obtain the vigor and productivity of Brazilian pastures, a Pasture Strength Index (PVI) was generated by integrating the α (intercept) and β (slope) coefficients, derived from the linear regression of the vegetation index (NDVI) over time (2000 to 2017). Pastures with low PVI values were located throughout the Caatinga biome, in the MATOPIBA region of the Cerrado biome, in the eastern portion of Mato Grosso do Sul, southeastern of Mato Grosso and northwestern of Goiás. These areas are associated to regions of higher water deficit, as shown by the relationship between the PVI and the total annual precipitation (R² = 0.40) and evapotranspiration. For the Cerrado biome, the PVI showed high spatial correspondence with the green biomass and percent green cover. Green biomass and percent green cover were generated from extrapolation of field data to the spatial resolution of MODIS images. The areas with lower PVI values in the Cerrado biome also had lower green biomass (< 6000 kg ha-1 ) and percent green cover (< 47%) during the growing season. Considering the accumulated green biomass in the growing season, it was observed that the Cerrado’s cattle stocking rate could increase from 1.11 AU ha-1 (real cattle stocking rate) to 2.56 AU ha-1 (potential cattle stocking rate). The real cattle stocking rate in 2015 was generated through the integration of the 2006 Livestock Census data with the Livestock Production data for the year 2015. The potential cattle stocking rate was obtained from the relationship between the forage production (green biomass and gross primary productivity - GPP) and the forage demand of one animal unit (1 AU = 450 kg). The potential of intensification was determined from the difference between the actual and the potential cattle stocking rates. For all of Brazil, the cattle stocking rate in 2015 was 0.97 AU ha-1 , reaching a potential of 3.60 AU ha-1 , that is, the potential for intensification was 2.63 AU ha-1 . The greatest potential of intensification occurred in the South region (3.62 AU ha-1 ), and the lowest in the North (2.13 AU ha-1 ) and Northeast (2.22 AU ha-1 ) regions of Brazil.Item Nanocompósitos biocompatíveis de poliuretana com hidroxiapatita e nanocelulose(Universidade Federal de Goiás, 2018-04-02) Arantes, Thaís Moraes; Alcantara , Glaucia Braz; http://lattes.cnpq.br/6408676855110487; Lião, Luciano Morais; http://lattes.cnpq.br/2647529909397336; Lião , Luciano Morais; Camargo, Emerson Rodrigues de; Rabelo, Denílson; Oliveira, Emília Lima de; Castro, Carlos Frederico de SouzaPolyurethane nanocomposites were prepared with nanoparticles of hydroxyapatite and/or nanocellulose in order to obtain biocompatible materials. The nanocelluloses were obtained from sugarcane bagasse, seeking to evaluate their use as a source of cellulose nanofibers. The conditions of extraction and separation of the nanocelluloses were investigated. The effect of time and concentration of sulfuric acid was studied, resulting in particles with reduced size and homogeneity in the size distribution without cellulose degradation. The cellulose nanocrystals that presented the best results regarding suspension staining, crystallinity index, thermal properties, particle size and Zeta potential were those hydrolyzed in 50% H2SO4 at 45 ° C for 2 hours. For the synthesis of the hydroxyapatite (HA) nanoparticles, a multivariate statistical analysis was carried out using a factorial design with resolution 23 . From which an empirical model was created that allows the control of the shape and size of the hydroxyapatite nanoparticles. HA nanoparticles with sizes varying from 8 nm to 600 nm were formed by oriented coalescence growth mechanism. The structure was confirmed by images of Electron Transmission Electron Microscopy and Scanning Electron Microscopy. The hydroxyapatite nanoparticles presented a well-defined nanorod shape with a narrow size distribution. It was observed that the model was statistically significant and the main parameter for the growth of crystals in the hydrothermal process was the temperature. Polyurethanes derived from castor oil were synthesized without residues of their monomers. The insertion of the nanoparticles into the polymer matrix improved the thermal stability of the composite. Finally, the cell viability assay showed that polyurethane nanocomposites with hydroxyapatite are biocompatible and in this way can be used as biomaterial.Item Avaliação da área queimadas no bioma cerrado: proposições para o monitoramento e conversação(Universidade Federal de Goiás, 2015-03-03) Araújo, Fernando Moreira de; Ferreira Junior, Laerte Guimarães; http://lattes.cnpq.br/8647270006257055Fire is an important ecological and environmental disturbance phenomenon in the Cerrado biome, which is influenced by climatic, ecological, cultural and economic factors. Burning biomass promotes change in the structure and composition of the soil, accelerates the erosion and sedimentation processes, promotes seed germination, renewal of grasses and releases large amounts of trace gases and aerosols into the atmosphere. This research seeks to understand the location patterns and the recurrence of burned areas to the Cerrado biome according to their different geographical regions from the land cover and land use class, and climatic variables. In particular, we evaluated quantitatively the performance of the MODIS MCD45A1 product for the Cerrado biome, in accordance with the different land use and land cover classes depending on the landscape, using as reference 130 randomly selected burned area polygons, and four randomly selected medium resolution orbital images, both from the month of September. In addition, we analyzed the burned areas spatial and temporal patterns in Brazil, considering both the territorial limits of the six biomes (i.e. Amazônia, Caatinga, Cerado, Mata Atlântica, Pampa and Pantanal) and their main land cover and land use classes (PROBIO MMA). At last, for burned areas greater than 2 km², we evaluated their patterns (spatial and temporal) and frequency of recurrence (burned areas that intersect more than 50%), as well as their interanual and seasonal climatic variations from vegetation index (EVI), precipitation (TRMM) and evapotranspiration (MOD16) images. These images were analyzed in association with the four groups of recurrence (burned areas with recurrence every four years) to determine the different burning regimes and the pre and post burning vegetation responses. The MCD45A1 polygons (September) had good relationship with the reference mapping (Landsat base) (r² = 0.92) and also with the hotspots (MOD14 and MYD14 - monthly data) (r² = 0.89). The omission error found is high, but this is associated with landscape structure patterns, as found for the four reference images. The Product MCD45A1 even with spatial and temporal limitations promotes temporal mapping consistency and provides understanding the behavior and impacts of the burned on the Cerrado landscape. Among the Brazilian biomes, Cerrado is the one with the highest record of fires between 2002 and 2010 (73%), followed by Amazon (14%), while 81% of the records of the burned areas occur on the remnant vegetation cover class. The records of the burning recurrences in the Cerrado focus on the remnant class, 59% whereas the frequency of recurrence presented a higher proportion up to 3 times for the period 2000-2013. For the four groups of recurrences analyzed after the first fire record, 2002, the vegetative vigor records declines, especially after 2010, on average 4% for the remnant classes and 3.5% for the anthropogenic. The minimum distance between the fragments presents that 42% of recurrences analyzed are between 1-2 kilometers, providing greatest spatial concentration.Item Efeitos do tratamento com a Hev b 13, extraída do látex natural de Hevea brasilienis, na resposta inflamatória de ratos com sepse(Universidade Federal de Goiás, 2017-03-06) Araújo, Lilhian Alves de; Mrué, Fátima; http://lattes.cnpq.br/2424858504979076; Silva Júnior, Nelson Jorge da; http://lattes.cnpq.br/6544526824923185; Silva Júnior, Nelson Jorge da; Reis, Paulo Roberto de Melo; Gomes, Clayson Moura; Pelli, Milton Adriano de; Silva, Cláudio Carlos daSepsis is an infectious disease characterized by severe systemic inflammatory response. Rupture of the complex equilibrium between inflammatory mediators in the acute phase of the disease leads to exacerbated production of proinflammatory cytokines, with consequent hypotension, increased capillary permeability, organ lesions and death. Recent research using the Hev b 13 protein derived from natural Hevea brasiliensis (rubber tree) latex has demonstrated important anti-inflammatory and immunomodulating effects. The aim of this study was to investigate the effects of Hev b 13 on the systemic and tissue inflammatory response of septic rats. To that end, cecal ligation and puncture (CLP) was performed on male Wistar rats and after six hours, the animals were randomized into groups and subcutaneously treated with doses of 0.5; 2.0 and 3.0 mg/Kg of Hev b 13. Next, the animals were subdivided into three different times (1, 6 and 24 hours after treatment) for blood sample collection and euthanasia with removal of the lungs and liver. Leukocytes, tumor necrosis factor- alpha (TNF-α) plasma and tissue levels, interleukin (IL)-6, IL-10, and IL-4 and histological slides were analyzed. The results demonstrated that treatment with the Hev b 13 protein prompted a significant decline in total and differential leukocytes, as well as the production of TNF-α and IL-6, associated with an increase in IL-10 and IL-4 in plasma and lung tissue. Moreover, it restricted the morphopathological changes found in the lungs, including neutrophil infiltration, swelling and alveolar thickening. In the liver, it increased IL-10 production and inhibited TNF-α and IL-6, in addition to reducing hemorrhage, sinusoidal inflammatory infiltrates and hydropic degeneration in histological assessment. We conclude that Hev b 13 displays anti-inflammatory and immunomodulating activity capable of attenuating lung and liver lesions in rats during acute sepsis, with potential for clinical applications.Item Metodologia para avaliação de riscos ambientais em áreas urbanas da região metropolitana de Goiânia-GO(Universidade Federal de Goiás, 2012-06-21) Assunção, Simone Gonçalves Sales; Oliveira, Leandro Gonçalves; http://lattes.cnpq.br/4995825091971711; Oliveira, Leandro Gonçalves; Miziara, Fausto; Formiga, Klebber Teodomiro Martins; Scalize, Paulo Sérgio; Mascaró, Juan LuisThis paper aims to propose a new method for assessing environmental risks based on the Ecological Risk Analysis method proposed by Faria (1983). Starting from the main scientific methods used for environmental risk assessment, methods of urban planning and environmental sustainability indicators used in models of environmental risk assessment, the new method is tested in the area around Mingau creek, in the neighborhood Parque Amazônia, in Goiania, Goiás, where it had been applied the method proposed by Faria (1983) and also in the vicinity of Santo Antonio creek, located in Aparecida de Goiânia, Goiás. This method consists in obtaining data from the premise socioeconomic and the physical environment of the study site, determining a rank for each risk factor. Subsequently, these data are checked with the physical medium through an array that uses the aggregate sum of the levels divided by two, rounded statistically when necessary. The results show, generally, the interrelation between the environment factors the physical and socioeconomic environment and reveal in a clear, objective and direct that the environmental risks of the physical environment are interrelated and submitted to each factor inserted in the premise socio-environmental, particularly the direct effects that social factors on the print environment, the deemed to be interdependent. In the method de Faria (1983) each factor is naturally hierarchical individually and that the intersection matrix of the aggregation is by obtaining the intensity of damage indicators, which are the anthropic factors interfering on the natural environment, with indicators sensitivity of damage, that for each natural factor is adopted and an indicator refers to the ability of resistance and resilience of the physical environment. So, are crossed, the risk matrix, the intensity of damage with a sensitivity of damage and gives the level of ecological risk for each natural factor, differently. In this new method more directly, we obtain the level of risk to each factor, whether physical or socioeconomic and then the results are intercepted in a single array of aggregation, which results in the environmental risk of the interrelationship of factors jointly allowing demonstrate a more comprehensive and systemic results of environmental risk assessment.Item O jogo das posições sociais: educação em ciências e a formação do cidadão(Universidade Federal de Goiás, 2020-12-21) Ataide, Jefferson Fagundes; Mesquita, Nyuara Araújo da Silva; http://lattes.cnpq.br/6971106875143413; Mesquita, Nyuara Araújo da Silva; Oliveira, Dijaci David de; Genovese, Luiz Gonzaga Roversi; Shuvartz, Marilda; Prata, Rita VilanovaIn this research, citizenship occupied the position of analytical category, on which the objective of investigating its interconnections with curricular, conceptual, and historical elements was proposed under the foundation of Pierre Bourdieu's sociology. It is a qualitative investigation developed through an association between bibliographic and documentary research. On the first, a review of the literature of the narrative type was developed in consideration of events that are preponderant for western and Brazilian citizenship. Then, a systematic review was structured about the same concept present in scientific articles that articulated the idea with Science Education. For this, three databases were selected: Education Resources Information Center (ERIC), Scientific Electronic Library Online (SciELO); Digital Library of Theses and Dissertations of the Federal University of Goiás (BDTD / UFG). The stage characterized as documentary research followed the directions of the Discursive Textual Analysis (methodological framework). Interpretations were based on the assumptions of Pierre Bourdieu's praxiological method (analytical framework). Conceptions of citizenship have historically been linked to struggles in social fields. In the case of the Brazilian Educational Field, even before its formal existence, one perceives the strategic character of the monopolization of cultural capital by an elite minority, as well as the need for a minimum perpetuation of some knowledge and rights to follow the rise of a new worldview, that of capitalism. It was found that Science Education has a fundamental role in promoting dialogues about the formation of the agent / citizen. However, there are still few studies of a conceptual nature on citizenship in this area of knowledge. National curriculum documents, such as the BNCC, have a strong impact on the definition of the direction of a nation, but they must not hide the foundations that produce and maintain social inequalities. The movement to produce knowledge about the relationship between citizenship and education is an essential step for decision-making under the critical-reflexive bias. Movement that nourishes the minority categories to remain in (re) existence.Item “Eu não sou tarefeira!” - tarefas de articulação didática para a organização histórico-crítica do ensino de biologia com a Educação de Jovens e Adultos(Universidade Federal de Goiás, 2023-07-03) Avelar, Lucas Martins de; Paranhos, Rones de Deus; http://lattes.cnpq.br/9743767959125352; Paranhos, Rones de Deus; Costa, Cláudia Borges; Messeder Neto, Hélio da Silva; Silva, Graziela Lucchesi Rosa da; Guimarães, Simone Sendin MoreiraEste estudio está vinculado a la Red de Investigación en Enseñanza de las Ciencias en la Educación de Jóvenes y Adultos y al Centro Memoria Viva - Documentación y Referencia en Educación de Jóvenes y Adultos, Educación Popular y Movimientos Sociales en Goiás (CMV-GO). La tesis problematiza la necesidad de discutir la Enseñanza de la Biología en la Educación de Jóvenes y Adultos más allá del concepto de marketing de la tarea docente. La investigación tiene como método el Materialismo Histórico-Dialéctico y tiene como objetivo comprender la relación entre la enseñanza del saber biológico y la enseñanza, en el movimiento hacia la constitución de la educación de adultos, para explicar qué tareas de articulación didáctica son necesarias para la organización de la enseñanza de la Biología. con la modalidad desde la perspectiva histórico-crítica. La investigación es de carácter bibliográfico, basada en enfoques historiográficos y teóricos. Se utilizaron fuentes de texto e imagen de contenido verbal y no verbal. Para la historiografía, fueron seleccionados materiales didácticos, informes y documentos de orientación didáctica de iniciativas de educación de adultos disponibles en el Portal de los Foros de EJA do Brasil. También se analizaron dos ediciones del libro Biología Educativa: nociones fundamentales, de Antônio Almeida Júnior, obra de gran influencia en la enseñanza del saber biológico en Brasil, a lo largo del siglo XX. La investigación teórica recurrió a la sistematización de elementos históricos en relación sintética con la Psicología Histórico-Cultural, la Pedagogía Histórico-Crítica y Gramsci. Los análisis se realizaron a partir de la cadena singular-particular-universal y consideraron dos relaciones: valorización y sistematización del saber biológico en la educación de adultos y enseñanza, aprendizaje y desarrollo en sentido histórico-crítico. Los resultados indican que la organización de la enseñanza del saber biológico en la educación de jóvenes y adultos ha estado marcada por conceptos en disputa, de los cuales se destacan los siguientes: Higienista-civilizadora, Técnico-instrumental y Educación Popular Crítica. Se defiende la tesis que: la organización histórico-crítica de la enseñanza de la Biología con la Educación de Jóvenes y Adultos implica el aporte teórico a la superación de la concepción burguesa del maestro cambiador de tareas, con la sistematización de tareas de articulación que fundamentan el quehacer didáctico. Como aporte, se esbozan dos tareas de articulación con miras a orientar el trabajo didáctico, a saber: 1) Responder a los interrogantes de la materialidad de la organización de la enseñanza de la Biología con la EJA en el momento histórico actual y 2) Elaborar, a partir de las respuestas, objetivos generales de organización docente que dan lugar a acciones de estudio docente para la actividad de enseñanza del saber biológico con la modalidad. En cuanto a la primera tarea, las preguntas se responden desde lo entendido estratégicamente, a la luz de los escritos de Gramsci, como elementos de posición (¿Por qué enseñar? - ¿Para qué enseñar? - ¿Cuándo enseñar?) y movimiento (¿Qué enseñar? - ¿Con quién enseñar? - ¿Cómo enseñar?). La segunda tarea se despliega a partir de la primera y permitió la elaboración de dos objetivos generales de organización docente: Posicionalmente - Enseñar Biología con la EJA porque es necesario engendrar medios colectivos de lucha por el derecho, por la formación de un mundo materialista histórico-dialéctico concepción y superación de ideas naturalizadoras sobre los jóvenes y adultos y sus posibilidades de desarrollo; Sobre el movimiento - Enseñanza de los fundamentos de los sistemas conceptuales biológicos, mediados por las relaciones sociales concretas que constituyen los sujetos de la EJA, a partir de la elaboración de tareas de estudio problematizadoras, para aprendizajes instructivos que enriquezcan el trabajo creador.Item Processos erosivos lineares nas bacias dos Rios Claro e dos Bois, afluentes do Rio Araguaia no Estado de Goiás: relações com a cobertura vegetal e uso da terra(Universidade Federal de Goiás, 2010-08-19) BARBALHO, Maria Gonçalves da Silva; CASTRO, Selma Simões de; http://lattes.cnpq.br/4460827622247417The pattern of land use and occupation of the Cerrado associated with the expansion of the agricultural frontier, in the last 40 years, has been interpreted as causing environmental impacts observed him during this period, especially those related to intensive deforestation and indiscriminate use of areas with soils with low or null agricultural capability, although capable of extensive pastures. The Erosion processes have been described as the most significant, positioned after the remarkable loss of biodiversity, the most important and extensive in area. The present thesis analyzes the relationship between the land use valued at historical series started in the decade of 1975, agricultural suitability of land use pattern and the erosion and silting sites of the two combined basins for purposes of this study, called basins of the rivers Claro and Bois, tributaries of the upper Araguaia river in the state of Goiás. This area was considered in previous studies as the most affected by deforestation among the five sub-basins that make up the upper Araguaia river basin. The research was based an integrated analysis of the physical environment and biota components of the focus area, with base on remote sensing and GIS and pedotransfer criteria. The results are presented as scientific papers and reveal that the most intensive phase of deforestation occurred in the 1980s, when the Forest Formations were most penalized originally, followed by the Savanna Formations, that the conversion occurred in favor of extensive pastures, for which the area has good suitability soil and relief associates; that the numerous of linear erosion impacts, 395 linear erosion features placed in degraded pastures are concentrated in these areas, which predominate low discrepancies between suitability and actual use. As evidenced in the spatial analysis, it is confirmed the presence of 395 linear erosion features associated with degraded pastures. It is concluded that the area supports the pattern of initial occupation of the Cerrado by its conversion to pasture and that environmental impacts arising from the management of them more than this type of use.Item Pagamento por serviços ambientais para catadores de material reciclável: oportunidades e desafios(Universidade Federal de Goiás, 2015-07-31) Barbosa, Cleidinaldo de Jesus; Ribeiro, Francis Lee; http://lattes.cnpq.br/1763392088652134Law no. 12.305/2010 ...Item Conservação de mamíferos no cerrado e em Goiás(Universidade Federal de Goiás, 2012-12-19) Barreto, Bruno de Souza; Miziara, Fausto; De Marco Júnior, Paulo; http://lattes.cnpq.br/2767494720646648Increasingly biodiversity has lost diversity around the globe because of the way the human population have used natural resources. To reduce the impacts caused by human activity, conservation units (CU) have been created to ensure the maintenance of biodiversity. However, many conservation units were not established following scientific criteria and its efficiency can therefore be questioned. In this study we tried to evaluate the efficiency of conservation of the Cerrado based on species richness and beta diversity of mammals currently and in accord to climate change expected for 2080. We show through gap analyzes that species are represented in the current system both in the current climate and in the future. However, they have become rarer within CUs with climate change. We show that CUs do not capture a greater diversity than expected by chance. It is expected a larger number of species within the CUs in 2080, however, the number of species outside them will also be greater. As for beta diversity, there will be a reduction of the index in 2080 and both outside and within the UCs expected on average the same value. Climate change became UC’s Cerrado more inefficient, there will be an increase in the number of threatened species because of climate change interfering in the spatial arrangement of species on the Cerrado. This draws attention to the evaluation of systems of protected areas consider the spatial-temporal dynamics of the species.Item Manejo e monitoramento de impactos sobre o ecossistema em áreas protegidas de cerrado: estrutura da vegetação, gramíneas exóticas e incêndios(Universidade Federal de Goiás, 2019-07-05) Batista, Flávia Regina de Queiroz; Ramos Neto, Mario Barroso; http://lattes.cnpq.br/7182178358444899; Ferreira Júnior, Laerte Guimarães; http://lattes.cnpq.br/8647270006257055; Ferreira, Laerte Guimarães; Faria, Karla Maria Silva de; Cianciaruso, Marcus Vinícius; Ferreira, Nilson Clementino; Taitson, GuilhermeThe Cerrado is the richest, perhaps the most threatened savannah in the world, and only 3% of its area is protected by law. These are extremely valuable and strategic areas for the conservation of the Cerrado, but suffer numerous external and internal pressures. Among the main management concerns for the Conservation Units (UC) of the Cerrado are fires and biological invasion. This work investigates how the interference of the management and the dynamics of the fire and the invasion of exotic grasses alter the phytophysiognomies of cerrado, and is divided in chapters that investigate respectively: 1) the difficulties in producing a map of sufficient accuracy to support studies of dynamics of vegetation structure; 2) the effectiveness of the current fire management system and the challenges of integrated fire management in the last two decades; 3) the invasion by exotic grasses and their relation with the topography of the terrain, tracks and roads in and around the study area. Landsat 8 images from a period of 5 years from 2013 were used and calculated for 5 different time intervals - monthly, inter-monthly, annual, yearly, quinquennial - sets of metrics based on 18 indices derived from reflectance values of the bands of these images besides the values of reflectance of the bands, data sampled in the field and semiautomatic classification for the mapping of the vegetation classes of the National Park of Emas (PNE). From a replicable model it was possible to elaborate a map with 89% accuracy and nine classes of phytophysiognomies, reducing the costs and the subjectivity of the manual work of data collection and posterior corrections. Using metrics elaborated from a digital elevation model and data of presence and absence of Urochloa sp on internal tracks and along the edges of the UC. Four models were tested using morphometric parameters, distances to tracks and roads in contrast to the presence or absence of the species. The results point to the importance of anthropic disturbances, terrain topography, and indicate that the force of water in its runoff is very relevant in establishing the species in new areas. In order to understand the spatial and temporal behavior of fire in the Emas National Park (PNE), the frequency of burnings for the different phytophysiognomies was analyzed, the correlation between the number of heat spots and the extent of the scars and the influence of the environmental variables surface, precipitation and accumulation of biomass). The scars of burned areas, heat sources, climatic variables - rainfall and temperature of the earth's surface (°C) - dry biomass surface and accumulated biomass for burned and unburned areas were analyzed. The annual peak of heat sources pointed with great accuracy to the occurrence of burnings in the PNE area, the number of outbreaks showed to be a good indicator of scar occurrence and size, the extent of area with dry biomass at categories 'very high' and 'critical' is a risk indicator of large fires and a reasonable predictor of areas that serve as a blockade to the spread of fires. The current fire management plan through firing and natural burning during the dry season has brought advances in fire prevention, but it is necessary to consider the use of prescribed controlled burns.Item Efeitos de microcistinas em Piaractus brachypomus (Actinopterygii, Characidae) e o perfil do consumo de peixes pela comunidade da UFG(Universidade Federal de Goiás, 2017-06-08) Bezerra, Roberto Araujo; Nogueira, Ina de Souza; http://lattes.cnpq.br/3877834258990173; Nogueira, Ina de Souza; http://lattes.cnpq.br/3877834258990173; Vieira, José Daniel Gonçalves; Oliveira, Leandro Gonçalves; Jardim, Fernando Antônio; Dias Júnior, WalterThe world's fishery production is constantly growing, with expansion of aquaculture parks, fish farms and fish-pay, however, these activities can trigger damages to aquatic systems. The process of eutrophication is characterized by the excess of nutrients available in the water, which when associated with high temperatures and luminosity, provide cyanobacteria blooms, some of which are toxic. Microcystins pose risks to human and other animal health due to the consumption of contaminated fish and can cause serious problems for the aquatic community. The present study had as main objective to evaluate the mutagenic damages that toxic blooms of Microcystis aeruginosa and Microcystis panniformis in different densities of cells can cause when exposed to the Piaractus brachypomus (pirapitinga), native species of the Amazon basin and commercialized in fish farms and fish-pays of the Goiânia metropolitan region, and to evaluate the profile of fish consumption by the community of the Federal University of Goiás. The results showed that even at low densities, the effect of microcystins generated different genomic damages in fish. Juveniles presented erythrocytic nuclear alterations exposed to M. aeruginosa - reniformes: 33%; binucleate: 28.6%; micronucleus: 28.1% and exposed to M. panniformis reniformes: 6.43%; binucleate: 75.5%; micronucleus: 2.4%. There was a higher concentration of microcystins produced by M. panniformis cells. As for the profile of the academic community, more than 80% consume fish, since tilapia is the most preferred species among respondents (22.4%). Of these, only 49.6% go to fish-pay and the main reason for going is leisure with family or friends (46.7%), however, only 21.7% take into account the hygiene of the place, but are unaware of the quality of the waters of these places, as well as that of fish. It was concluded in this study that the group most threatened by the action of cyanotoxins are the fish consumers themselves due to the low concentration found in the muscular tissues and that when investigated, some do not reach the peak of detection, passing unnoticed by the human population.
