Distribuição e ocorrência de aranhas de sub-bosque de quatro ambientes florestais no planalto do Rio Grande do Sul, Brasil

Este trabalho teve como objetivo geral avaliar a riqueza, abundância e composição das assembléias de aranhas de sub-bosque em quatro ambientes florestais na FLONA de São Francisco de Paula, RS, Brasil. Essa reserva está situada no planalto do Rio Grande do Sul e, desde sua criação, explora madeira para corte. O tipo de manejo empregado é o de longo tempo de rotação dos talhões, com corte seletivo. A área se caracteriza como um mosaico da paisagem formado de quatro ambientes florestais: floresta ombrófila, plantação de araucária, plantação de Pinus e plantação de Eucalyptus. Essas diferenças na estrutura da paisagem poderiam se traduzir em diferenças na estrutura da vegetação, o que pode influenciar a distribuição e ocorrência das assembléias de aranhas na área. Portanto, os objetivos específicos desta pesquisa foram 1) comparar a estrutura das assembléias de aranhas de sub-bosque entre os diferentes ambientes e entre os talhões, assim como inferir possíveis processos que poderiam estar influenciando os padrões encontrados, 2) avaliar como características da estrutura da vegetação nos diferentes ambientes influenciam o padrão de distribuição encontrado e 3) verificar as respostas da abundância, riqueza e composição das assembléias de aranhas são diferentes levando-se em conta diferentes níveis taxonômicos. As aranhas presentes na vegetação entre 1 e 2,5 m de altura foram coletadas pelo método guarda-chuva entomológico em duas unidades amostrais (25 m  2 m) aleatorizadas dentro de cada um de três talhões de cada tipo florestal, em seis ocasiões durante 2003 e 2004. Todos indivíduos foram identificados em nível de família e os adultos em nível de gênero e espécie. A cobertura vegetal foi estimada através de 50 medidas dos toques da vegetação em uma vara de 2,5 m de altura dentro de cada unidade amostral no inverno e no verão de 2003. Os toques da vegetação foram separados em árvores, arbustos, lianas, pteridófitas e gramíneas. Foram coletadas um total de 8440 aranhas, divididas em sete guildas, 29 famílias, 80 gêneros e 132 espécies. A área de plantação de Eucalyptus apresentou a menor abundância de aranhas de sub-bosque em relação aos outros ambientes para a abordagem em nível de famílias, mas a plantação de Eucalyptus foi diferente somente da plantação de Pinus para a abordagem em nível de espécie. A abundância das aranhas de sub-bosque foi a característica estrutural que mais diferiu entre os diferentes tipos ambientais durante todo estudo. Os resultados, porém, foram influenciados pela abordagem taxonômica. A diversidade de aranhas de sub-bosque não apresentou diferenças entre os ambientes, porém, houve diferença entre talhões apenas em uma estação do ano para os níveis de gênero e espécie. A abundância de aranhas de sub-bosque teve correlação positiva com a idade dos talhões. A composição das assembléias de aranhas de sub-bosque teve maior relação com as características inter-talhões do que inter-ambientes, e os tipos de vegetação influenciaram na composição das famílias de aranhas. Além disso, a abordagem taxonômica alterou os padrões de agrupamento das assembléias. Processos locais como limitação de recursos para estabelecimento e ao crescimento das populações em nível local parecem estar atuando na estruturação das assembléias de aranhas de sub-bosque nessa área. Concluiu-se que o tipo de manejo empregado (longa rotação) na área para exploração de madeira não afeta negativamente a diversidade de aranhas do sub-bosque, provavelmente por que há o desenvolvimento de estruturas da vegetação do sub-bosque que proporcionam condições para a ocorrência e o estabelecimento das assembléias de aranhas nesse local.

As escolhas das carreiras minimizam o impacto da política de cotas? O caso do estado do Rio de Janeiro

Esta pesquisa busca verificar se a política de cotas, incluída na legislação federal brasileira por meio da Lei nº 12.771 de 2012, ao tornar obrigatória a reserva de vagas no ensino superior numa combinação de cor/raça, renda e origem em rede pública de ensino médio, tem caminhado para alcançar seu objetivo de forma a minimizar as dívidas racial e social brasileiras, causadas, entre outras, pela escravidão que por décadas se perpetuou no país. Para isso a pesquisa focou na escolha das carreiras dos estudantes cotistas e não cotistas de uma forma geral, além de por sexo e turno. Buscará evidenciar a hipótese de que o público-alvo da política de cotas ao escolher carreiras menos prestigiadas ou com menor retorno financeiro, finda por minimizar o impacto da mesma e sugere que política complementar seria necessária. Para classificar e agrupar as carreiras, o trabalho utilizou a base de dados do Instituto Brasileiro de Geografia e Estatística - IBGE que lista as carreiras pela remuneração média percebida. Após contextualização da desigualdade racial e social, da educação como promotora do desenvolvimento econômico e social, das experiências americana e brasileira com ações afirmativas, da exposição da legislação que dispõe sobre o tema e de estudos já realizados, e da importância da avaliação das políticas públicas, são analisados os dados do Censo Escolar do Ensino Superior, do ano de 2013, do Instituto Nacional de Estudos e Pesquisas Anísio Teixeira – Inep, no que tange a escolha de carreira dos cotistas e não cotistas, além de por sexo e turno. A abrangência da pesquisa se restringiu às universidades, centros e institutos públicos situados no estado do Rio de Janeiro que, em diferentes graus e épocas já adotaram a política de cotas, a fim de verificar a hipótese. Ao final a pesquisa demonstra que o modelo de regressão que inclui as IES e o tempo de vigência da política se mostrou estatisticamente significativo sinalizando a forte influência das IES e do tempo sobre a razão de cotista e que, ao contrário do que se pensava, os cotistas escolhem as carreiras mais bem remuneradas ou de mais prestígio. Além disso, demonstra que o sexo feminino, da mesma forma que os estudantes de turno noturno, de uma forma geral, cotistas e não cotistas, optam por carreiras menos remuneradas indicando a necessidade de política complementar que: fomente a participação do sexo feminino nessas carreiras, avalie as carreiras e vagas oferecidas no turno noturno e corrija distorções que ampliem o leque de possibilidades para os alunos de ensino superior.

Conselho Municipal de Saúde de Pedras de Fogo - PB: um estudo sobre participação

The present study aims to understand the process of Participation of the Health Council- CMS in the formularization, implementation and control of the Municipal health plan of Pedras de Fogo, through four criteria of quality of participation considered by Demo (1993): representation, legitimacy, base participation, and self-responsibility. The criteria of representation is related to the quality of politics of the representative over the representings. Legitimacy is related to the politics` quality of the process of participation based on norms and rules that stipulate the participation, the base participation is a necessary political support so that the power authorization directed to the representings can be effective and the self-responsibility refers to the capacity of being responsible when it concerns to the public service or property. Through the descriptive and exploratory study a qualitative method was adopted to consider the conditions of the participation of the twelve council members of the City council of Health of Pedras de Fogo, through a formulated Instrument based on the criteria of DEMO (1993). It was concluded that the quality of the participation of the council members of the CMS of Pedras de Fogo understands essential aspects of the criteria of quality considered by Demo (1993) but it shows fragilities as unfamiliarity with the norms that legitimize the performance of the council; unfamiliarity of its condition of being an agent and the importance of the participation of the base for the reinforcement of its participation, as well as inertia related to the check and rendering of accounts on its performance. This way it makes sense that the participation of the council in the four criteria of quality of politics considered in this paper needs to improve

Comunidades tradicionais em áreas protegidas: convergências e lacunas da Política Urbana e Ambiental na Reserva de Desenvolvimento Sustentável Estadual Ponta do Tubarão/RN

This work presents a reflection on possibilities and boundaries of consolidation and expansion of human settlements characterized as traditional communities that are located within protected areas, using as study reference the State Sustainable Development Reserve Ponta do Tubarão, at Rio Grande do Norte state. The main topics highlight the conflict between the right to housing and the prevalence of fundamental rights of traditional populations, opposed to the diffuse right to environment, according to the regulatory framework of the Brazilian Urban and Environmental Policies. At the same time that these settlements, historically built, are substantiated by the principles of recognition of rights to traditional populations, they are in a condition of complexity to the resolution of conflicts in its urban dimension and lead to an impairment of natural sites. This work questions how the instruments of land use and occupation are defined and relate to environmental planning, especially considering that the settlements are located in Permanent Preservation Areas (APP). It aims to further the discussion of the urban dimension in settlements, characterizing its formation and growth process, to identify the gaps and convergences between the Urban and Environmental Policy, under the foundations of a socio-environmental approach. The results spotlights the conflicts between occupation and natural areas, inferring that the definition of Urban Policies instruments and its integration with Environmental Policies instruments account for essential and priority actions to the achievement to the rights to a sustainable city, as determined in the Cities Statute and environmental protection goals, defined for the Conservation Units

Caracterização ecológica dos peixes recifais do Atol das Rocas

The present work was carried out at the Atol das Rocas (3º 51 S; 33º 49 W), the only atoll of the South Atlantic and the first Brazilian marine protected area. It was guided by the following hypothesis: the composition of the fish communities varies in agreement with the position of the pools; in other words, with or without permanent ocean connection. To test the validity of this hypothesis, the fish abundance was estimated in the connected pools (Barretinha/Barreta Falsa) and unconnected ones (Cemiteriozinho/Âncoras), carrying an ecological characterization of the fishes that inhabit these pools. Additionally, the structural complexity of the sampled places was also evaluated intending to verify the variations of the abundance and diversity of fishes in function to this factor. By the fact of this research was being carried out through the limits of a conservation unit, the samples was realized using visual census techniques. The results generated through uni and multivariate analytic techniques allowed the evidence that decisive factor in the density, richness and diversity variations of fishes are linked to the substratum type (Hard / Soft bottom) and not by the fact that the pool are or are not connected permanently to the ocean. In relation to the structural complexity; 58% of the variations in the diversity of fishes were attributed to changes in the structural complexity, while 12% of the variations in the abundance were attributed to the structural complexity

O gênero geastrum pers. (phallomycetidae, basidiomycota) em algumas áreas de Mata Atlântica e Caatinga no Rio Grande do Norte, Brasil

A taxonomic survey of representatives of the genus Geastrum took place during the rainy season from 2006 to 2009 in four districts in the state of Rio Grande do Norte: Parque Estadual Dunas do Natal (Atlantic Forest), Mata do Jiqui EMPARN (Atlantic Forest) and Estação Ecológica do Seridó (Caatinga). Fourteen species were recorded: G. entomophilum, G. fimbriatum, G. hirsutum, G. javanicum, G. lageniforme, G. lloydianum, G. minimum, G. morganii, G. ovalisporum, G. pectinatum, G. saccatum, G. schweinitzii, G. setiferum and G. triplex. Of these species, eleven occurred in the Atlantic Forest and six in the Caatinga. A new species has been recorded to science, G. entomophilum, other as a first record for Brazil, G. morganii, six new records for the Northeast, and ten new records for Rio Grande do Norte. The material was tumbled in the Herbarium UFRN. Additionally, a survey of the species of the genus deposited in the Herbarium UFRN was accomplished, resulting in 244 herbarium specimens belonging to thirty-three species. Of these ones, twenty-three were collected in Brazil and ten are from Czech Republic, Europe, as donation from the VZ Herbarium

Uso e disponibilidade da vegetação lenhosa em comunidades rurais no Rio Grande do Norte

The aim of this study was to test the Ecological Apparency Hypothesis comparing two rural communities in João Câmara (RN) and Remigio (PB), in the Northeast of Brazil. This hypothesis assumes that plants are perceived, known and used by human populations according to their local availability. The most used species would be the ones that are more available in the forest (apparent), and apparently suffer greater pressure of use. Communities were consulted through semi-structured interviews. In Remigio 42 people were interviewed, and 50 in João Câmara. The importance of each species was evaluated considering the distinction between citations from current and potential uses. The ethnobotanical information was associated with phytosociological parameters collected by the point-centered quarter method in forested areas, where 50 transects were distributed in each community, and 4,000 individuals sampled in total. Based on the interviews, 58 useful species were recorded, 42 genera and18 families. In the phytosociological study 30 species, 22 genera and 12 families in João Câmara, In Remígio were identified 34 species, 22 genera and nine families.The species were grouped into 11 categories of use. The ecological appearance was confirmed only in the João Câmara, which best explained the relationship between local availability and use of timber resources. Positive correlations were observed also between the technology category VUpotential and dominance. The point-centered quarter was efficient to test appearance, however, further studies through the point-centered quarter method are recommended

O canto das senhoras :Análise do discurso do sujeito coletivo (DSC) de velhas mulheres da Ponta do Tubarão, no Rio Grande do Norte

The participation of women of more than 60 years of age in the social ritual of the creation of the Reserva de Desenvolvimento Sustentável Estadual ( Sustainable Development State Reserve ) at Ponta do Tubarão, in the state of Rio Grande do Norte, is the central object of this research. This work is an attempt to analyze the oral discourse of these women, to understand the historical participation in this ritual, pointing out the actions for dehistoricization that, in the Western world, take women out of the community scene making their roles less important or invisible as agents of social construction. The reflections that take place in this research, using as a starting point, the example of a traditional fishing community on the Brazilian coast, and denounce the mechanisms of male domination that try to silence their hábitus, such as: the discourse of power (that is responsible for the permanent division of sexual structures) and of the correspondent social and cultural division. The present research respects the oral discourse of the Elderly Women as a significant practice of community life in Diogo Lopes in Macau, Rio Grande do Norte. The creation of the community of RDSE in Ponta do Tubarão as an instrument for political and social management is also accepted here as a process conducted by various social actors that react to developmental threats that have interfered with and are still trying to interfere with the equilibrium of the regional ecosystem. The methodology used in the research is supported in the oral discourse of these women as social representations of a focus group, on which the method of the Análise do Discurso do Sujeito Coletivo (DSC) ( Collective Subject Discourse Analysis ) is applied

Teoria da despesa pública: uma leitura ético-constitucional em busca do possível da reserva

Brazilian law passes through a crisis of effectiveness commonly attributed to the extravagance of fundamental rights and public shortage. However, public finances are not dogmatically structured to solve the conflicts around the limitations of public spending. There are ethical conditioning factors, like morality, proportionality and impartiality, however, these principles act separately, while the problem of public shortage is holistic. Also, the subjectivity of politics discretionary in the definition of public spending, which is supported in an indeterminate concept of public interest, needs material orientation about the destination of public funds, making it vulnerable to ideological manipulation, resulting in real process of catching rights. Not even the judicial activism (such as influx of constitutionalism) is shown legally appropriate. The Reserve of Possible, also presents basic ethical failure. Understanding the formation of public shortage is therefore essential for understanding the crisis of effectiveness of state responsibilities, given the significant expansion of the state duty of protection, which does not find legal technique of defense of the established interests. The premise of argument, then, part of the possibility of deducting minimal model ethical of desire to spend (public interest) according to objective parameters of the normative system. Public spending has always been treated disdainfully by the Brazilian doctrine, according to the legal character accessory assigned to the monetary cost. Nonetheless, it is the meeting point between economics and law, or is in the marrow of the problem of public shortage. Expensive Subjects to modernity, as the effectiveness of fundamental rights, pass necessarily an ethical legal system of public spending. From the ethical principles deducted from the planning, only the democratic principle guides the public spending through the approval of public spending in the complex budget process. In other words, there is an ethical distancing of economic reality in relation to state responsibilities. From the dogmatic belief of insufficiency, public spending is evaluated ethically, according to the foundations of modern constitutionalism, in search of possible of the financial reserve, certain that the ethics of public economy is a sine qua non condition for legal ethics.

Reserva de cargos e empregos públicos a pessoas com deficiência: instituições federais de ensino no RN

With a focus on the need for effectiveness of fundamental rights of persons with disabilities, this dissertation held a scientific research to analyze the degree of implementation of reservation of positions and public jobs to people with disabilities in the Brazilian State, because the 1988 Federal Constitution expressly determined such a reservation in your article 37, VIII. Highlight that this subject is enough evidence, given the large number of open public competition in recent years in Brazil, as well as recent proposals to grant equal rights to blacks (Bill nº 6,738/2013). In addition, the wording the constitutional device comes fomenting heated discussions on the subject, which are flowing on the doors of the judiciary and are spicy because such protection Microsystem vulnerable group has several gaps in the regulation of this policy. However, the research produced, unlike other related theme, does not address the problem of inefficiency in its constitutional theory, that is, abstractly, but also focuses on a specific analysis of this ineffectiveness within Brazilian society, so that research based on a bibliographical analysis, plus a study case law, at the national level, as well as in field research, while case study, focusing on the technique of the analysis of everyday life, because it was believed that the degree of realization of the constitutional norm debated is not yet a satisfactory degree of effectiveness. Soon, the methodological procedures chosen confirmed such a hypothesis and contributed to the study of realization of the fundamental right to work of people with disabilities in Brazil, the light of a Constitutional State, proposing a constitutionally appropriate model the greater effectiveness of the constitutional norm studied
