REUNIÃO & DISPERSÃO: UM ESTUDO DOS DISCURSOS SOBRE A REFORMA DO CÓDIGO FLORESTAL NOS JORNAIS FOLHA DE S.PAULO E O ESTADO DE S. PAULO

Este trabalho aborda os textos sobre a reforma do Código Florestal nos jornais Folha de S.Paulo e O Estado de S.Paulo entre maio de 2011 e junho de 2012 com o objetivo de descrever as características da cobertura dos dois jornais sobre o tema. Trata-se de uma pesquisa qualitativa, descritiva, documental e bibliográfica, na qual teorias da Análise do Discurso de linha francesa e o conceito de ética discursiva da teoria da ação comunicativa de Habermas serviram como subsídio à análise. O corpus se compõe de 80 textos, de um universo de 450 pesquisados. Constatou-se que os dois veículos endossaram o discurso de defesa da reforma, que foi o mesmo dos representantes do agronegócio. Mas suas redações atuaram de formas distintas. A da Folha foi influenciada pela linha editorial da empresa. A do Estadão se revelou mais independente e deu mais espaço para as vozes dos cientistas e ambientalistas, contrários à reforma. Com isso, atendeu aos pressupostos de uma ética discursiva.

Estudo de viabilidade técnico-ambiental para implantação de parques eólicos: um estudo de caso em um fragmento do litoral setentrional do Rio Grande do Norte/Brasil

The use of energy from renewable sources is increasingly demanded by society, especially aeolian - whose raw material is wind. Investments in wind power have become significant in Brazil with emphasis on the Northeast and in particular the Rio Grande do Norte state. According to the Empresa de Pesquisa Energética (Energy Research Company) (2012 ) , investments in the state grew significantly since 2002 with a total accumulated power, by 2013, of approximately 3,400 MW . Even with the early experiences of exploitation of wind energy in 2002, it is still considered new and requires further study referring to the likely changes in the environment and society. In this case, it is of growing and urgent importance to deeply study the wind still in the survey phase of the project, ie , at the beginning of decision making on the most feasible to implement these parks site. Given the above, the question is: from a technical and environmental analysis, how to identify viable areas to install Aeolian parks, taking into account the factors of the environmental dynamics that are relevant to minimize the negative results to the environment and the society? Thus, this study conducted a study on technical and environmental feasibility, proposing a methodology of exploration of feasible wind farms in coastal areas. The study area was a fragment of the northern coast of Rio Grande do Norte and its natural landscape units were identified through the environmental characterization of the area, as well as it was elaborated the map of the land cover, restriction homes and urban areas and Permanent Preservation Areas - PPAs. The environmental fragility was subdivided in the fragility of the natural dynamic, mapped through relief, soils and geology of natural units, and the fragility of the ecosystem, originated by the land cover map. In addition to these maps, it was generated the wind resource for an area from a height of 50 and 100 meters. The intersection between the fragility maps, PPAs and Restriction of homes superimposed on maps of wind potential, provided the map of feasibility of Aeolian parks, resulting in the most favorable areas for its facilities in a technical and environmental point of view. From this study, the entrepreneur can evaluate whether or not to proceed with the studies in this area and especially decrease potential conflicts with society.

Preferência e competição alimentar em um grupo de Sapajus flavius em fragmento de Mata Atlântica em Caaporã – Paraíba – Brasil

Feeding is the primary selective pressure in all forms of animals. Nutritional ecological models predict consequences of preferred and non-preferred food consumption on behavioural, physiological and morphological adaptations. At same time, socioecological models infer socio-organizarion patterns based on feeding competition faced by animals. A list of preferred foods, and inferences regarding the intensity of feeding competition and its behavioural consequences are information of much importance for management of populations in fragments. In this work we observed the feeding behavior and spatial positioning of a group of more than 100 blond capuchin monkeys (Sapajus flavius) that inhabit a fragment of Atlantic forest, surrounded by sugarcane plantation. We compared the consumption of different food items with their monthly availability in the area to define the preferred and fallback food items. We recorded the vocalizations of aggression and the inter-individual distance (area of Minimum Convex Polygon/n individuals) to infer the type of food competition experienced by animals. In the year studied the fruit feeding time correlated with top consumed fruit productivity, indicating preference for fruits. Our data indicate that the species Elaeis sp., Cecropia palmata, Inga spp. and Simarouba amara are the preferred food items in the diet. Available all year round and uniformly distributed, sugarcane was a regular item in the diet and its was characterized as a staple fallback food for this group. Although fruits are preferential food items, direct competition rate did not correlate to fruit productivity in the area, maintaining the high rates throughout the year (2.45 events/ hour). The inter-individual distance index positively correlated with rain fall indicating scramble food competition. The number of neighbours of females carrying infants was smaller when fruit productivity is low, indicating that females carrying infants are suffering increased indirect competition. Our data indicates that blond capuchins in this fragment make use of sugar cane as a staple fallback food, which evidence the importance of sugar cane landscape for the survival of this critically endangered capuchin species in fragmented habitats in Northeast Brazil. A preliminary list of preferred and important foods is offered, and can assist in the choice of trees for reforestation, better fragments to be preserved and areas of release and translocation of animals. We did not observe an increase of contest competition while using preferred foods, but when using staple FBF. This may be due the altered environment, which results in high competition food throughout the year. Both the food preference as the social and behavioral consequences of high food competition experienced by animals in this fragment must be accompanied over the years to ensure the survival of this population.

Florística e ecologia de briófitas em um fragmento de restinga no extremo sul do Brasil

A Área de Proteção Ambiental da Lagoa Verde é composta por um mosaico de unidades ambientais. Entre elas, destaca-se um fragmento de mata de restinga que reúne características físicas e microclimáticas para o estudo de ecologia de briófitas. Este estudo teve por objetivo realizar o levantamento das espécies de briófitas; fornece novas ocorrências de briófitas para o Rio Grande do Sul; avaliar a influência dos gradientes longitudinal e vertical na distribuição de briófitas; quantificar a variação da diversidade de briófitas nos gradientes longitudinal e vertical. Foram identificadas 51 espécies de briófitas como novas ocorrências para o Rio Grande do Sul, sendo 11 musgos e 40 hepáticas. Além do local de estudo foram identificadas espécies que estavam no herbário SP. No estudo dos gradientes longitudinal e vertical foram identificadas 53 espécies de briófitas, sendo 17 musgos e 36 hepáticas. Através da análise dos transectos e da inclusão dos forófitos subdivididos em três zonas de altura, foram coletadas amostras terrícolas e corticícolas. As briófitas respondem aos gradientes, através dos fatores microclimáticos (luminosidade e umidade), em relação ao aumento da riqueza e mudança na composição de espécies. A partição aditiva da diversidade de briófitas quantificou a variação da composição de espécies em cada gradiente. A diversidade entre cada nível dos gradientes longitudinal (umidade) e vertical (luminosidade) variou em torno de 40% e 50%, respectivamente. Em conclusão, o estudo sobre a ecologia de briófitas gerou conhecimento sobre a diversidade e biogeografia das espécies; contribuiu para o entendimento da distribuição das briófitas em função dos gradientes longitudinal e vertical, por influência de fatores microclimáticos e; revelou a variação da composição de espécies em função dos gradientes horizontal (umidade) e vertical (luminosidade).

Padrões de organização das assembleias de aves florestais em uma paisagem fragmentada de Floresta Atlântica

Brazil is home to one of the richest avifaunas the world, which is subject to high levels of environmental degradation, in particular forest fragmentation. The Atlantic Forest biome depicts this history of devastation and today remains as small isolated fragments on highly degraded landscapes. This project aimed to evaluate the effects of forest fragmentation in an area with Atlantic Forest remnants in northern Paraná (Brazil) on the distribution and the organization of assemblage of forest birds and tested the hypothesis that the structure of the assembly in the fragments is different than expected by chance. We did four qualitative samplings of birds in three sets of forest fragments in the landscape, each with three fragments: large, medium and small. The method applied in the sampling was point counts along transects, traveled randomly for four hours in each fragment. Samples were taken in two periods: from September to November / 2013, and between March and May / 2014. The structure of the meeting was assessed by rates of co-occurring species (Checkerboard and CScore) and α diversity patterns (wealth) and β (turnover of species), while the landscape structure was analyzed from the parameters: area, distance between fragments, fractal dimension, edge density, fragment shape index and nuclear area index. The null hypothesis of no structure in the assembly of birds in the landscape was tested with null models from the co-occurrence indexes. The effects of landscape structure on the assembly of the structure were analyzed by the Mantel test and principal component analysis (PCA). The assembly of the structure in the landscape showed a pattern of spatiotemporal organization significantly different from that expected by chance, revealing a structure most influenced by segregation of the species. The fragments showed significant differences in richness, unlike sets of fragments, indicating relative homogeneity in the landscape structure. The differences between the size and the distance between the fragments significantly influenced the patterns of organization of the meeting of forest birds in the landscape and patterns of α and β diversity, indicating that the higher the fragment and smaller distances between them, more the standard of species cooccurrence is different than expected by chance. Thus, the fragmented landscape of remnants of the northern Paraná Atlantic Forest still has availability of environmental resources and physical characteristics that allow a persistent organizational structure of the assembly of forest birds in space over time.

COMPOSIÇÃO FLORÍSTICA E CARACTERIZAÇÃO SUCESSIONAL COMO SUBSÍDIO PARA CONSERVAÇÃO E MANEJO DO PNMCBio, SOROCABA - SP

O trabalho foi realizado no Parque Natural Municipal Corredores da Biodiversidade (PNMCBio), em Sorocaba -SP, com o objetivo de avaliar a composição florística do componente arbóreo e o estágio sucessional de uma área de floresta nativa de aproximadamente 31 hectares. Para tanto, foram alocadas 64 parcelas de tamanho 10 x 10 m, distribuídas aleatoriamente na área, sendo coletados todos os indivíduos com CAP igual ou maior que 15 cm. Estimou-se a diversidade por meio do índice de diversidade de Shannon (H’) e a equabilidade por meio do índice de Pielou (J’). As espécies foram caracterizadas nos grupos sucessionais, síndrome de dispersão, categorias de ameaça, amplitude de distribuição e indicadoras do estágio de regeneração. Foram amostrados 1088 indivíduos, distribuídos em 79 espécies, 54 gêneros e 29 famílias, sendo o H’ estimado em 3,421 e o J’ em 0,78, valores próximos aos encontrados em outras áreas de formações vegetacionais similares. Foram identificadas quatro espécies ameaçadas de extinção, 11 espécies endêmicas da Mata Atlântica e duas espécies restritas à Floresta Estacional Semidecidual no domínio da Mata Atlântica. O fragmento encontra-se em estágio médio de regeneração, sendo de suma importância sua conservação e manejo para a manutenção da biodiversidade local e regional.

La polisemia del sacrificio. Política y fragmento de la communitas latinoamericana

El sacrificio, en tanto que elaboración metafórica de las reciprocidades sociales, se trata aquí en su compleja polisemia, y de la cual se contempla la dialéctica obje­tivo-subjetiva mostrada en los escenarios rituales. Para ello se detiene el análisis en momentos de rupturas en la cohesión so­cial durante el período pre-hispánico y del mundo indígena mesoamericano contem­poráneo, tomándolo como antecedentes, para proponer una explicación desde tales categorías para la sociedad actual en los procesos de fragmentación que rompen los vínculos recíprocos en el seno de las diversas comunidades latinoamericanas, que se derivan en expresiones sacrificiales que participan en la reconstitución de las fracturas sociales ocurridas en nuestro territorio, y restablecen, en palabras de Humberto Maturana, la pegajosidad amoro­sa que es inherente a la condición humana.
