Diatomáceas (Ochrophyta) do rio Guaraguaçu, litoral do Paraná, Brasil

Banca: Thelma Ludwig [Orientador]Banca: Hermes Moreira Filho [ Co-orientador ]Data da defesa: 2005.02.24Dissertação (mestrado) - Universidade Federal do Paraná, Setor de Ciências Biológicas, Programa de Pós-Graduação em Botânica. Defesa: Curitiba, 2005Inclui bibliografiaResumo: O inventário florístico das diatomáceas do rio Guaraguaçu baseou-se em vinte e nove amostras coletadas em seis estações selecionadas ao longo do rio, em abril e outubro de 2003, durante o período de influência de maré baixa e alta, respectivamente. O rio localiza-se na bacia hidrográfica litorânea paranaense, entre os municípios de Paranaguá, Pontal do Paraná e Matinhos. As amostras de plâncton foram obtidas com auxílio de rede e as de perifíton por coleta e remoção das diatomáceas aderidas aos talos de macrófitas aquáticas submersas. Lâminas permanentes foram analisadas e 555 táxons marinhos, estuarinos e dulcícolas foram identificados, descritos, mensurados, ilustrados e comentados, quando necessário. Em amostras de plâncton foram determinados 481 táxons e nas do perifíton, 487. Registraram-se 186 táxons pela primeira vez para o estado do Paraná. Chaves dicotômicas foram elaboradas para a identificação das espécies encontradas. Ampla variação morfológica foi constatada para algumas espécies, incluindo formas ainda não registradas na literatura em Capartogramma crucicula, Desikaneis gessneri, Fragilaria javanica e Gomphonema butantanum, entre outros. O índice de Jaccard, calculado para as amostras de plâncton provenientes da segunda coleta, mostrou um decréscimo na similaridade florística entre as estações, no sentido nascente - foz, demonstrando a influência da salinidade na composição de espécies das amostras analisadas. Noventa e seis táxons foram observados em amostras concentradas não oxidadas, e destes apenas 46 foram constatados com plasto, sugerindo que parte das espécies pode ter sido carreada para o interior do rio pelo movimento de maré no momento em que as amostras foram coletas. Sugerem-se pesquisas interdisciplinares, envolvendo o estudo do regime hidrológico e da influência do sistema de marés, em conjunto com análises biológicas e físico-químicas, através de coletas periódicas, para melhor compreensão da dinâmica dos ambientes reófilos influenciados pelo regime de marés.

Guaraguaçu river is located in the littoral hydrographical basin in State of Parana, among the cities of Paranagua, Pontal of the Parana and Matinhos. The samples of plankton were obtained making use of a net and the samples of periphyton for collection and removal of the diatoms adhered to the stems of submerged aquatic macrophytes. Permanent slide samples were studied which contained 555 marine, estuarine and freshwater taxa, which were identified, described and mensured, illustrating and commenting, if necessary. Analysis of the samples of plankton resulted in 481 identified taxa and, 487 as for periphyton samples. Besides, 186 taxa were registered for the first time to State of the Parana. Dichotomic keys were elaborated to the identification of the species. Ample morphologic variation was observed on some species, including still not registered forms in literature namely, Capartogramma crucicula, Desikaneis gessneri, Fragilaria javanica and Gomphonema butantanum, among others. Jaccard index was calculated for plankton samples proceeding from the second collection, indicating a decrease in the floristic similarity among the collection points downstreams, demonstrating the salinity influence of the composition of species in analyzed samples. Ninety-six taxa were observed in unoxidated intent samples, while only 46 were evidenced with cellular content, suggesting that species could have been carried upstream on account of tide movement at the moment of collection of samples. Suggested research interdisciplinary, comprehending the study of the hydrologic regimen, influence of the system of tides, biological analyses and physic-chemistry, including periodical collections for better understanding of river environments dynamics influenced by tide regimen.

The role of religious beliefs and practice in the lives of older men in residential nursing homes: a case study of the role of Islam in nursing homes in Saudi Arabia and the implications for policy and practice

Increasing attention in the social science literature, particularly within the sociology of religion, psychology and gerontology is being given to the role of religion in the lives of older people. Moreover, research has repeatedly identified religion as a significant coping resource throughout human life. Through the use of the biographical narrative method of interviewing, and the subsequent thematic analysis of the data, this study focuses on the role of religious beliefs and practices in the life experiences of older men in two selected Saudi nursing homes. The research demonstrates the positive influence of religion on adjustment processes in later life in general and specifically on adjusting to life in a nursing home. The study shows that religion serves as an important thread of integration in older men's lives. As they grew older, the respondents in this research had become more religious and more involved in religious practices. The study found that religion was an important dimension in their everyday life. All of them had integrated religious beliefs and practices into their lives to help them respond positively to the difficulties which they experienced. Above all, they strongly believed that leading a religious (Islamic) life was their duty as Muslims and this would also lead to their being rewarded by God in the Hereafter, as they believed that a truly happy life would come after death. Based upon its findings, the study highlights the need to acknowledge the importance of religion in the social care provision for older people in Saudi Arabia, for example, in counselling, in social work provision in general and within residential homes for older men in particular
