Abstract: A presente tese tem como objectivo aumentar o conhecimento da flora diatomológica de água doce de Portugal e inclui as seguintes partes: 1) uma compilação dos táxones citados para o país (Arquipélagos dos Açores e Madeira incluídos), baseada numa análise bibliográfica; 2) um atlas ilustrado em microscopia óptica e electrónica dos táxones mais frequentes e abundantes em Portugal Continental, baseado na análise de amostras de cursos de água e albufeiras de todo o país; 3) um estudo detalhado de dois grupos taxonomicamente problemáticos, como o complexo Gomphonema tergestinum - G. rosenstockianum e a descrição do Achnanthidium caravelense, uma nova espécie frequente e abundante no Norte de Portugal, em águas com concentração baixa a moderada de nutrientes; 4) a aplicação de métodos baseados em diatomáceas epilíticas litorais e índices diatomológicos (Índice de Poluosensibilidade Específica) na avaliação do estado ecológico de albufeiras, de acordo com os requisitos da Directiva Quadro da Água; ABSTRACT: This thesis intends to increase the knowledge of the freshwater diatom flora from Portugal and comprises the following parts: 1) the compilation of the taxa already cited for the country (Azores and Madeira Archipelagos included) based on analysis of the literature; 2) the illustration under light and scanning electron microscopy of the most frequent and abundant taxa, based on samples collected in watercourses and reservoirs from the entire Continental Portugal; 3) a detailed study of two problematic species complexes, with taxonomic clarification of the Gomphonema tergestinum and G. rosenstockianum complex and description of Achnanthidium caravelense, a new taxon frequent and abundant in soft waters with low to moderate nutrient content in northern Portugal; 4) the application of methods based on epilithic littoral diatoms and diatom indices (Specific Polluosensitivity Index) for the assessment of the ecological status of reservoirs in accordance with the requirements of the Water Framework Directive.
