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 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 Biodiversidade e padrões de distribuição da anurofauna do Parque nacional das emas e entorno(Universidade Federal de Goiás, 2009-03-30) KOPP, Katia A; BASTOS, Rogério Pereira; http://lattes.cnpq.br/6015137404238990Composition and diversity of anuran amphibians in preserved and disturbed environments in the Cerrado of the State of Goiás, Mid-West Brazil. The Cerrado is the second largest biome of Brazil, with an approximate area of 2 million km², which represents about 23% of the total area of the country. Despite the high conversion of natural areas of the Cerrado in agricultural areas and pastures, comparative studies that address aspects of the composition and diversity of frogs from adjacent areas in different states of conservation are lacking. Thus, this study aimed to address taxonomic richness and community composition of anuran amphibians in twelve water bodies located in preserved areas (inside the National Park of Emas - PNE) and disturbed areas located around the PNE to test whether the structure of frogs communities is different in preserved and disturbed areas and whether species richness is correlated with descriptors of the heterogeneity of habitats. Were recorded 25 species of frogs belonging to nine genera of five families in the 12 water bodies sampled. Species richness was higher in disturbed than in preserved areas. Diversity and equitability were significantly higher in preserved water bodies (P <0.05) while dominance was higher in disturbed water bodies. An analysis of percentage of similarity (SIMPER) showed that the percentage of dissimilarity between the compared groups was 52.26%. The analysis of similarity (ANOSIM) showed significant results on differentiation between groups (Global R = 0.17, P = 0.04). Species richness was not related to any descriptor of heterogeneity. Geographic distance was related to species composition between sampled water bodies (r = -0.35, p = 0.01). At least two non-exclusive factors may be responsible for patterns of species composition and diversity of frogs found in the environments studied: a) the disturbance caused by human action in the use of natural areas for agriculture and livestock enables greater richness of species in disturbed areas, which is consistent with the hypothesis of intermediate disturbance, b) the migration between adjacent ponds allows the maintenance of communities and patterns of species composition. Thus, although species richness was lower in preserved water bodies, the highest diversity recorded in such habitats demonstrates their importance for the maintenance of community integrity and viable frogs populationsItem Conservação de espécies em áreas de monocultura de soja no sudoeste goiano: uma avaliação usando larvas de anfíbios anuros(Universidade Federal de Goiás, 2009-11-06) VAZ-SILVA, Wilian; BASTOS, Rogério Pereira; http://lattes.cnpq.br/6015137404238990The basic knowledge of the answer of the species to the anthropic and natural perturbations on environments is the first step in the development of management strategies to the conservation biology. This study analyzes the pattern of occurrence of anurans species in relation of habitat, considering two different landscape uses from Jataí municipality, southwestern Goiás State, Central Brazil. Anurofaunal composition on Jataí represented 24% of anuran diversity of Goiás State, with great similarity with Aporé municipality, hydrographic sub-basin of the river Corrente. The relation between the species richness in seven municipalities with environmental and social attributes were non-significant. Considering the tadpoles assemblages in Jataí were sampled 40 ponds (24 distant of the monoculture and 16 located in the proximities of the monoculture). The study registered 4.529 specimens, classified in four families, 18 anuran species, presenting Scinax fuscovarius, Dendropsophus minutus and Eupemphix nattereri the most common species. The mean richness of species by sampled pond was significantly different in the families Hylidae and Leptodactylidae. The results showed that ponds distant of monoculture were more heterogeneous and possess a biggest diversity of species. The Canonical Correspondence Analyses showed the biggest predictive power to the environmental variables: predator types; distance of forest fragments; depth; and, hydroperiod. Spatial and temporal attributes were important to the species composition. Ponds distant to the monoculture presented (in mean) a bigger number of types of microhabitat and significant relation between the availability and the utilization by tadpoles. Significant difference was observed between niche breadths in the categories, with biggest values in the ponds distant to the monoculture. The species in ponds distant to the monoculture showed high plasticity in the environmental occupancy. The relation between spatial niche overlap and ecomorphological and phylogenetic patterns to the pars of the species were non-significant in the multivariate context. The results will subsidize actions directed to the management in agricultural areas in the scope of Conservation Biology
