The Gastropoda is one of the best studied classes of marine invertebrates. Yet, most species have been delimited based on morphology only. The application of DNA barcodes has shown to be greatly useful to help delimiting species. Therefore, sequences of the cytochrome c oxidase I gene from 108 specimens of 34 morpho-species were used to investigate...
Article
Annelid polychaetes have been seldom the focus of dedicated DNA barcoding studies, despite their ecological relevance and often dominance, particularly in soft-bottom estuarine and coastal marine ecosystems. Here we report the first assessment of the performance of DNA barcodes in the discrimination of shallow water polychaete species from the sout...

Project
O projeto proposto enquadra-se no âmbito da prioridade estratégica para Promover uma Aquicultura Ambientalmente Sustentável, Eficiente em Termos de Recursos, Inovadora, Competitiva e Baseada no Conhecimento. As atividades a desenvolver neste projeto visam a redução dos índices de mortalidade nas culturas de mexilhão da Lagoa de Albufeira, resultantes da invasão por espécies não-indígenas. Este objetivo prende-se com as recentes mortalidades verificadas nas estruturas de produção de mexilhão da Lagoa de Albufeira, causadas pela ocorrência de invasões biológicas, em particular do tunicado Styela plicata (Lesueur, 1823). Uma inspeção preliminar à Lagoa de Albufeira permitiu verificar a presença de várias espécies não-indígenas de tunicados, briozoários e moluscos, não apenas nas estruturas de produção de mexilhão, mas também noutras estruturas de substrato duro identificadas na lagoa, sendo os tunicados o grupo taxonómico com maior biomassa. Este projeto permitirá identificar as espécies invasoras na Lagoa de Albufeira, perceber a evolução da sua dinâmica populacional em função das condições ambientais, identificar os impactos das mesmas e determinar as áreas de risco de invasão, permitindo cartografar as áreas com maior aptidão aquícola. A proteção do potencial aquícola da lagoa será promovida através da identificação dos potenciais vetores de introdução das espécies invasoras e do desenvolvimento de técnicas de minimização dos efeitos adversos. Serão ainda investigadas aplicações que visem a valorização das espécies invasoras. No âmbito da Tarefa 1 será efetuada uma avaliação da produção mitilícola na Lagoa de Albufeira, com vista a perceber a evolução temporal da produção e das condições ambientais associadas às variações verificadas. Essa tarefa irá permitir estabelecer uma ligação estreita com o setor produtivo, com vista a ter o seu suporte na realização de todo o trabalho de amostragem e experimentação previsto. Na Tarefa 2 será avaliado o estado de invasão na Lagoa de Albufeira por organismos não-indígenas, através da identificação das espécies presentes na Lagoa de Albufeira e da determinação da sua abundância nas estruturas de cultura de mexilhão. A utilização de técnicas de análise molecular será a base do desenvolvimento da Tarefa 3, que consiste na identificação das espécies não-indígenas presentes na lagoa e dos potenciais vetores de introdução dessas espécies, tendo em conta o seu local de origem. Estes resultados permitirão definir estratégias de prevenção contra futuras invasões neste sistema lagunar e outros onde seja praticada a produção aquícola. A Tarefa 4 visa a identificação dos impactos das espécies invasoras, quer a mortalidade direta causada no mexilhão, quer outros impactos indiretos (e.g. competição trófica e produção de biodepósitos). A evolução temporal dessas espécies em função das variações nas condições ambientais será identificada na Tarefa 5, que permitirá perceber se as espécies invasoras são vulneráveis às alterações sazonais na lagoa, associadas à ocorrência de pluviosidade e redução da salinidade na massa de água. Essa informação, combinada com o conhecimento sobre outras condicionantes como a poluição e as restrições em termos de ordenamento, servirá de suporte à identificação de áreas com maior potencial aquícola para a moluscicultura, no âmbito da Tarefa 6. Por sua vez, a mitigação dos impactos destas invasões será investigada através da realização de ensaios experimentais desenvolvidos no âmbito da Tarefa 7, que irá identificar e validar a eficácia de métodos de remoção das espécies invasoras nas culturas de mexilhão. Atendendo à significância da biomassa dos tunicados presentes na Lagoa de Albufeira e noutros sistemas costeiros portugueses, será desenvolvida a Tarefa 8, visando a sua valorização, através da identificação do seu valor nutricional e potencialidade para desenvolvimento de aplicações médicas e farmacêuticas. A divulgação, publicação de resultados e sensibilização do público-alvo propostas pela Tarefa 9 serão conduzidas ao longo de todo o projeto, uma vez que serão os instrumentos essenciais para repercutir e potenciar os resultados obtidos. As informações com relevância científica serão apresentadas aos pares, enquanto os resultados essenciais para a gestão das invasões biológicas serão direcionados para os agentes envolvidos na atividade aquícola e de gestão da Lagoa de Albufeira. A Tarefa 10, dedicada à gestão e acompanhamento do projeto, promoverá a coordenação entre as várias equipas de trabalho e garantirá a boa execução técnica e financeira do mesmo.
