Superagui Praia Dissertation

Innovative approaches are needed to help understanding how species diversity is related to the latitudinal gradient at large or small scales. We have applied a novel approach, by combining morphological and biological traits, to assess the relative importance of the large scale latitudinal gradient and regional morphodynamic drivers in shaping the functional diversity of polychaete assemblages in shallow water habitats, from exposed to estuarine sandy beaches. We used literature data on polychaetes from beaches along the southern and southeastern Brazilian coast together with data on beach types, slope, grain size, temperature, salinity, and chlorophyll a concentration. Generalized linear models on the FDis index for functional diversity calculated for each site and a combined RLQ and fourth-corner analysis were used to investigate relationships between functional traits and environmental variables. Functional diversity was not related to the latitudinal gradient but negatively correlated with grain size and beach slope. Functional diversity was highest in flat beaches with small grain size, little wave exposure and enhanced primary production, indicating that small scale morphodynamic conditions are the primary drivers of polychaete functional diversity.

Abstract
Resumo: Conhecer as relações que se estabelecem em comunidades, envolvendo seus membros, suas lideranças, instituições e ambiente permite desvendar o espaço vivido e os elementos que os amalgamam. A comunidade da Barra do Superagüi, onde ocorreu este estudo, está no litoral norte do Estado do Paraná, sendo área de amortecimento de um Parque Nacional sujeito a restrições no que concerne ao uso dos recursos na mata, no mangue, na terra e no mar. O objetivo da pesquisa foi desvendar a percepção da comunidade de seu espaço vivido, considerando o encontro de saberes e fazeres entre anfitriões e visitantes. Tendo a metodologia qualitativa, as técnicas de pesquisa foram a observação participante, o caderno de notas e a entrevista oral com questões não estruturadas. A coleta de dados ocorreu nos espaços de convivência dos comunitários, tais como: as trilhas, a praia, restaurante, pousada, associações e o espaço escolar. A metodologia para a interpretação foi a Análise do Discurso do Sujeito Coletivo. Os resultados mostraram que neste espaço quando o número de turistas está além da capacidade confortável para os moradores, causa um stress comunitário em especial quando interfere nas atividades da vida doméstica. Foi percebido ainda que a atividade de pesca era a principal atividade de trabalho e renda naquele momento, mas que os pais já não se sentem estimulados a passar os conhecimentos para os filhos, os quais não se interessam em aprender. Em virtude deste fato percebeu-se que muitos pescadores estão investindo esforços em desenvolver alguma atividade voltada para o turismo. Ainda os resultados mostraram que existem lideranças comunitárias tanto nas organizações formais quanto nas informais, e que a comunidade necessita destes como apoio e fomentadores das ações que tem por fim um benefício coletivo. Foi possível concluir que a gestão do turismo deve partir da própria comunidade e a forma de turismo que melhor se adequa a este espaço é o solidário, sustentável e de base comunitária.

Abstract: Being aware of the relationships which become established in communities, involving their members, leadership, institutions and environment makes it possible to throw light upon the space lived in and the elements which make it up. This study took place in the community of Barra do Superagüi, on the north coast of Paraná, in the buffer zone of a National Park, which is subject to restrictions regarding the use of the resources in the forest, the mangrove swamp, the land and sea. It was ascertained that the community functions as an open system, as it is receptive to the external influences from channels of communication and from visitors, while being closed regarding the generation of work and income. The objective of the study was to reveal the community's perception of its space lived in, considering the meeting of knowledges and doings between hosts and visitors. Using the qualitative research methodology, the research techniques were participant observation, a field diary and oral interviews with nonstructured questions. The environments in which data was collected were from all the community members' areas of coexistence, such as trails, the beach, restaurants, hotels, associations and the school space. The methodology for the analysis was the Analysis of the Discourse of the Collective Subject. The results showed that in this space, when the number of tourists is above a capacity comfortable for the inhabitants, it causes stress on the community, in particular if it interferes in the activities of domestic life. It was also noted that fishing activity was the main activity providing work and income at that time, but that parents did not feel encouraged to pass their knowledge on to their children, who were not interested in learning. Due to this fact, it was noted that many fishers are investing their efforts in undertaking some activity geared towards tourism. Furthermore, the results showed that community leadership exists as much in formal as in non-formal organizations, and that the community needs these as support and encouragers for actions which aim for a collective benefit. It was possible to conclude that the management of tourism must begin with the community itself and that the type of tourism which is best suited to this space is based on solidarity, is sustainable, and is based on the community. The researcher participated as a grant-funded scholar of the Extension Program of the Technological Incubator of Popular Cooperatives, of the Federal University of Paraná (ITCP/UFPR). The data from this work in the project provided data for the dissertation, as data collected for the dissertation at some times supported the actions of the Project.
