Rosa, A., Cravo, A., Jacob, J., & Correia, C. (2022). Water quality of a southwest Iberian coastal lagoon: Spatial and temporal variability. Continental Shelf Research, 245(June), 104804

Rosa, A., Cravo, A., Jacob, J., & Correia, C.

The present work aims to characterize Ria Formosa water quality considering its spatial, and temporal variability at two scales: short-term (among seasons) and long-term to evaluate its evolution over the past 40 years, by comparing six historical datasets with data obtained in this study. To attain these goals, four field surveys under different seasons and/or weather conditions were conducted between 2017 and 2019 at seven sites along the Ria Formosa, covering the water bodies specified for this system. In situ measurements (temperature, salinity, pH and dissolved oxygen) and water sampling for determination of nutrients, chlorophyll a and suspended solids were taken every 2 h at each site, during complete semidiurnal tidal cycles. Moreover, these data were complemented with in situ data acquired at a high frequency (every 15 min) by a real time observational station deployed at an inner area, close to a main channel, where the anthropogenic pressure is more intense. Data analysis clearly depict a spatial variability pattern along the Ria Formosa, as well as a temporal heterogeneity, influenced by the contribution of precipitation, sediments, wind and water exchanges with the adjacent ocean. Between sampling sites, the lowest variability of water quality parameters occurred at the boundary coastal station, at the main inlet, in permanent connection with the ocean, while the maximum variability was found at both the lagoon edges, mainly due to the shallowness of the water column. Temporally, the highest concentrations of nutrients were obtained during the Wet/rainy conditions survey, under the influence of runoff. The lowest concentrations of nutrients were attained during the Summer, except for phosphate, due to consumption by phytoplankton. Although the sampling frequency along time has been limited, Ria Formosa water quality data from the last 40 years shows a decreasing trend in nutrients concentration and a marginal increase of dissolved oxygen, suggesting a water quality improvement over time, in contrast with other coastal lagoons that are showing a water quality deterioration due to an increasing anthropogenic pressure. Altogether, these are relevant aspects to consider regarding Ria Formosa present and future management, including climate change and anthropogenic pressures susceptibility assessment and to use them within an international context by comparison with other similar systems.

A Ria Formosa é a lagoa costeira mais importante do sul de Portugal, com grande influência nas trocas de água e de matéria com o oceano adjacente, as quais controlam a produtividade biológica destes ecossistemas intimamente ligados. Neste capítulo são apresentadas as características geomorfológicas da Ria Formosa e as características dinâmicas que a tornam um sistema bastante produtivo e peculiar, com forte impacto no oceano adjacente. São ainda apresentadas, pela primeira vez, as trocas através das três barras do setor oeste da Ria Formosa, em condições de maior produtividade biológica, típicas de Primavera, evidenciando a importância da interligação entre estes dois sistemas, particularmente num período sob afloramento costeiro.

A aprendizagem e a compreensão de como um sistema dinâmico como a Ria Formosa evolui ao longo do tempo é imprescindível para a sua preservação. Os satélites de Observação da Terra do programa Europeu Copernicus levam a bordo sensores que permitem medir parâmetros essenciais para o conhecimento da Ria Formosa, tais como: a temperatura, a topografia da superfície do oceano, a cor do mar, a cobertura vegetal e as mudanças no uso e cobertura da terra ao longo dos anos. O contributo dos satélites é fundamental para um conhecimento mais abrangente do sistema lagunar, de modo a complementar os sistemas de monitorização no habitat natural.

Energias limpas na Ria Formosa, o caminho da sustentabilidade

Pacheco, A., Gorbeña, E.G. & Sequeira, C., : Anílbal, J., Gomes, A., Mendes, I. & Moura, D.

O crescimento económico e populacional está entre os fatores mais importantes para o aumento do consumo energético mundial. Atualmente, a forma de energia que o Homem mais utiliza é a energia química (cerca de 80%), nomeadamente, combustíveis fósseis, como o petróleo, o carvão e o gás natural. No entanto, essas fontes são muito poluentes, pois a sua utilização é responsável pela emissão de substâncias nocivas para o ambiente e para a saúde pública. Um exemplo disso, é o aumento da concentração de gases com efeito estufa na atmosfera, como o dióxido de carbono (CO2), que é uma das principais causas do aquecimento global. Além da emissão de poluentes, essas fontes de energia não são renováveis, o que significa que estão sendo consumidas a uma taxa mais rápida do que a necessária para sua produção e, portanto, a sua disponibilidade é limitada e diminuirá ao longo do tempo.

Importância das plantas do sapal para reter os metais que chegam à Ria Formosa devido às atividades humanas

Silva, M.M., Duarte, D. & Chícharo, L., Aníbal, J., Gomes, A., Mendes, I., Moura, D. 

Os sapais são ecossistemas costeiros, na transição entre a terra e o mar, que se caracterizam por ser colonizados por plantas vasculares superiores, herbáceas e arbustivas, que apresentam grande resistência à salinidade, e que por isso se designam de halófitas. Estas plantas desenvolveram ao longo do tempo estratégias de adaptação, que lhes permitem resistir a períodos de submersão, mais ou menos longos, consoante se localizam em baixo, médio ou alto sapal.

Mulheres e o Mar

Bebianno, M. J

Se Portugal é um país de Mar, serão as portuguesas mulheres de Mar? Durante séculos, a História, a Cultura, a Iconografia, a Sociologia e a atenção mediática centraram as narrativas da nossa relação com o Mar na perspetiva masculina. Foram e são homens os celebrados descobridores e marinheiros, os pescadores e cientistas, os aventureiros e poderosos. E, no entretanto, onde estiveram as mulheres? Mais importante ainda, hoje, no início do século XXI, onde estão as “Mulheres e o Mar”?
Elsa Páscoa, jornalista e escritora, foi à procura delas. E nesta obra, lançada pela Diário de Bordo quando se celebra o Dia Internacional da Mulher, apresenta 36 perfis de mulheres, cujas vidas têm o Mar como paixão e vértice comum.

O capítulo 23 da Avaliação do Oceano do Primeiro Mundo (WOA I) concentrou-se na mineração marinha, e particularmente nas indústrias extratives estabelecidas, que estão predominantemente confinadas a áreas próximas à costa, onde são encontrados depósitos de águas rasas, agregados próximos à costa e depósitos de placer, e depósitos de fosfato de água um pouco mais profundos (Nações Unidas, 2017a). No momento da publicação, não havia depósitos de mineração em águas profundas (DSM) comercialmente desenvolvidos, mas uma avaliação das locações de mineração e atividade de exploração foi incluída. Desde o WOA I, o número de águas profundas (profundidades superiores a 200 m abaixo da superfície do oceano) aumentou tanto dentro das jurisdições nacionais dos Estados costeiros, insulares e arqueológicos, quanto além da Área (o fundo do mar, o fundo do oceano e o subsolo além dos limites da jurisdição nacional) sob a administração da Autoridade Internacional do Fundo do Mar (ISA).

A História da Ciência é a soma das histórias dos homens e mulheres que para ela contribuíram. Eles passaram as suas vidas angariando Informação, que uma vez tratada transforma-se em Conhecimento, o qual é compilado em artigos e livros. Muitas histórias da Ciência começam com um grande estrondo, mas esta história começou com um humilde clique. Numa fria manhã de inverno de 1988, um homem muito alto permanecia imóvel e sozinho numa estrada ventosa, tirando fotografias durante a maré baixa, aparentemente a nada de especial, tendo como pano de fundo uma zona lamosa de sapal na Ria Formosa. Esse homem, chamado Martin Sprung, repetiu esse singular ritual mensal, durante vários anos, sempre no mesmo local. Martin era um zoólogo alemão, que veio para o Algarve nos anos 80, para implementar um projeto luso-alemão com o objetivo de estudar a biologia da Ria Formosa. Esse projeto foi muito importante no desenvolvimento da licenciatura em Biologia Marinha e Pescas, na recém-criada Universidade do Algarve. http://hdl.handle.net/10400.1/17343

Recentemente, o CIMA foi abordado por vários autarcas, membros de organizações locais e regionais, e stakeholders da região algarvia, os quais gostariam de ter uma publicação em português, que pudessem consultar aquando da tomada de posições/decisões sobre questões ambientais costeiras. O produto desse desafio é este livro, o qual se destaca pela sua facilidade de leitura e adequação à divulgação científica da investigação realizada no CIMA. Deste modo, não é um livro monotemático, pretendendo pelo contrário uma abordagem sistémica a um alvo territorial, que neste caso é o sistema lagunar da Ria Formosa. Este livro visa transmitir conhecimentos científicos, em uma linguagem simples, mas cientificamente correta. Esse compromisso às vezes é difícil de alcançar. Portanto, cada capítulo contém caixas de texto que explicam os conceitos menos comuns e também um glossário no final do livro.

As praias lagunares encontram-se na zona entremarés do interior da Ria Formosa, em locais protegidos da ondulação. São ambientes onde há acumulação de sedimentos finos e areia, essencialmente sujeitos à ação das correntes de maré. As suas margens comunicam com sapais e canais de maré. Tanto as praias lagunares como os sapais detêm elevada importância ecológica e albergam inúmeras atividades económicas. As praias lagunares são naturalmente vulneráveis a intervenções humanas e naturais, porque têm uma reduzida capacidade de recuperação quando comparadas com as praias oceânicas. Um conhecimento mais aprofundado acerca da sua dinâmica atual e futura enriquece a sua conservação.

Effects of depuration on subsequent deterioration and shelf life of cultured grooved carpet shell clam Ruditapes decussatus during chilled storage

Mota F., Aníbal J. & Esteves E., Cortez Vieira, M. M., Pastrana, L., Aguilera, J.

The grooved carpet shell clam Ruditapes decussatus is one of the most consumed and valuable bivalves in the Mediterranean. As with other filter-feeding species, there are health risks associated with its consumption and specimens have to be depurated pending assessment of water quality of the environment where they originate. This study aimed to examine the effects of depuration on parameters of biological (mortality), physiological/commercial (condition index, CI, and percent edibility, PE), physicochemical (pH and TVB-N content), microbiological (TVC, Enterobacteriaceae and psychrotrophic bacteria counts) and sensory quality of commercially-sized clams originated from Ria Formosa (Algarve, south Portugal) stored at chill (5 ± 1 °C) temperatures. The median time to death t50 of non-depurated clams kept chilled for up to 30 days was much lower in the Summer compared to Winter, 12.1 vs. 20.1 days. The post-mortem changes in CI, PE, pH and TVB-N content of non-depurated clams were notably different between the different temperatures tested, 5, 15 and 25 °C. Depuration affected in different ways the level but not the general dynamics of the quality parameters of clams harvested in Summer, the season of peak clams’ consumption. However, eventual safety issues emerge long after habitual storage time and panelists’ sensory rejection.

Nanopharmaceuticals Principles and Applications

Nanopharmaceuticals are an emerging innovative domain of research that integrates nanotechnology and biotechnology applications. This technological development will permit producing unique nanopharmaceutical compounds used in the medical field, particularly in drug delivery. This book chapter focuses on organic (polymeric and lipid nanoparticles, dendrimers) and inorganic (magnetic nanoparticles and quantum dots) materials used to produce nanopharmaceuticals with different characteristics such as size, structure, chemical composition, and behavior enabling their use in different fields, one of which the drug delivery systems. Within drug delivery systems, special emphasis is given to vesicular (liposomes) and nanoparticulate carriers as they are the most explored at the market level. The biotechnological development, main features, and examples of applications of some types of nanostructures are discussed. Moreover, data available on sources, pathways, and effects of nanopharmaceuticals in the aquatic environment are discussed, with special emphasis on the environmental impact of these nanopharmaceuticals to the aquatic environment. Results indicate that there is no standard protocol for ecotoxicological testing and limited information exists on environmental impact assessment of nanopharmaceuticals. Thus, human and environmental safety guidelines are urgently needed to protect both the human health and the environment.

Sustainable Development of Water and Environment

Sea level rise is a worldwide concern as a high percentage of the population accommodate coastal areas. The focus of this study is the impact of sea level rise in the Guadiana Estuary, an estuary in the Iberian Peninsula formed at the interface of the Guadiana River and the Gulf of Cadiz. Estuaries will be impacted by sea level rise as these transitional environments host highly diverse and complex marine ecosystems. Major consequences of sea level rise are the intrusion of salt from the sea into fresh water and an increase in flooding area. As the physical, chemical and biological components of estuaries are sensitive to changes in salinity, the purpose of this study is to further evaluate salt intrusion in the Guadiana Estuary caused by sea level rise. Hydrodynamics of the Guadiana Estuary were simulated in a two-dimensional numerical model with the MOHID water modeling system. A previously developed hydrodynamic model was implemented to further examine the evolution of salinity transport in the estuary in response to sea level rise. Varying tidal amplitudes, freshwater discharge from the Guadiana River and bathymetries of the estuary were incorporated in the model to fully evaluate the impacts of sea level rise on salinity transport and flooding areas of the estuary. Results show an overall increase in salinity and land inundation in the estuary in response to sea level rise.

Fate and Effects of Anticancer Drugs in the Environment 

Extensive efforts have been devoted to assessing the environmental fate, effects, and risks associated with the presence of pharmaceutical compounds in the marine environment. Higher standards of living combined with aging and the increase of the world population contribute to frequent and highly diverse needs for the use of pharmaceutical compounds. Therefore, inputs of these substances has begun to be detected in the marine environment. Their sources are hospital, industrial, and sewage effluents in which these compounds cannot be properly treated. Therefore, the substances reach the marine environment in their chemical form or metabolized, and their fate in the aquatic systems, after long-term exposure to organisms at environmentally relevant concentrations, should be assessed. One of the groups of these pharmaceutical compounds includes cytotoxic pharmaceuticals applied in chemotherapy. These compounds, although having mutagenic, genotoxic, and teratogenic properties, have received less attention in environmental risk assessment, despite the progressive enhancement of their use with the increase of cancer incidence in the human population. Cytotoxic drugs have variable chemical structures and are used to kill tumor cells or inhibit their proliferation by different modes of action (MoA). The aim of this chapter is to report data regarding acute and chronic responses of cytotoxic drugs on nontarget organisms. An integrative approach of molecular and cellular effects is reported as a result of single or mixture exposures to assess the ecotoxicological potential, synergistic, additive, and antagonist effects of these drugs in biological systems of nontarget species at realistic environmental concentrations. These data are integrated to contribute to the environmental risk assessment of these compounds in the marine environment. Furthermore, recommendations are made for suitable biological models to assess the ecotoxicological effects of these compounds in marine organisms.

Loureiro C., Ferreira, Ó.

Sandy Beach Morphodynamics

In a simple definition, beach rotation is the opposing movement of the shoreline along the two ends of an embayed beach, driven by longshore and/or cross-shore sediment transport in response to seasonal or periodic changes in wave direction and/or gradients in wave energy. However, when considered in detail, the mechanisms, drivers and timescales of beach rotation are complex, resulting from non-linear interactions of cross-shore and alongshore hydrodynamic forcing, sediment transport and morphological change, developed over single or combined timescales that range from storm events to decadal rotation driven by climate-forced changes in wave conditions. In the context of global change, morphodynamic complexity of beach rotation processes is further compounded by rising sea levels and changes in wave climate, and impacted by artificial modification of beach environments along increasingly engineered coastlines. The spatial and temporal complexity of beach rotation mechanisms creates significant challenges to morphodynamic modelling and management of embayed beaches.

Inovação e partilha pedagógica na UAlg

Estratégias promotoras de aprendizagem ativa são uma caixa de ferramentas com uma ampla gama de aplicações e graus de complexidade. Algumas exigem mudanças profundas na estrutura do currículo e métodos de aprendizagem (e.g. “problem based learning” ou “flipped classroom”), outras são técnicas simples que levam apenas alguns minutos para serem preparadas e implementadas. Do último grupo, três estratégias de aprendizagem ativas podem ser facilmente executadas em praticamente todas as unidades curriculares, de qualquer curso de ensino superior: brainstorming, sondagens e estórias. Os objetivos dessas estratégias de aprendizagem são "acordar" os estudantes, integrá-los na sala de aula e fazê-los participar ativamente no processo de ensino-aprendizagem.

The microalga under study showed a total sugar concentration of 21.44 ± 0.46% (w/w). The effects of freeze-drying, oven-drying, freezing and thawing, chemical and the combination of hydrothermal and chemical pretreatments were evaluated. In the combined pretreatment different concentrations of H2SO4 and reaction times were also optimized. It was possible to determine that the sugar extraction yields more significant were 59.5% for the lyophilization, 6.2% with 6 cycles of freeze and thawing and around 100% for 2 and 4% (v/v) of H2SO4 at 121 °C for 30 min. Some of the methods that were described in this study are interesting to facilitate cost-efficient conversion of microalgal biomass into biofuels.

Biofuel production using microalgae attracted much attention because it can be cultured using CO2 and sunlight. With high carbohydrate content, microalgae have the potential to be used as a fermentation feedstock for bioethanol production. In present work, chemo-enzymatic saccharification of Chlorella sorokiniana microalgae were investigated. Chemical hydrolysis of the biomass followed by enzymatic hydrolysis and was also evaluated the effect of combining the two enzymes and the sequential addition. The effect of α-amylase concentrations was analyzed in ranged between 50 and 8000 U/g of biomass and for amyloglucosidase between 90 and 600 U/g of biomass. The higher concentrations showed the highest conversion of reducing sugars. The α-amylase concentration 8000 U/g of biomass presented a conversion of 43.06 ± 2.92% (w/w), while amyloglucosidase with 600 U/g of biomass obtained 76.57 ± 6.42% (w/w). The combination of two enzymes simultaneously was more efficient than the sequential addition for low enzyme concentrations (α-amylase 50 U/g and amyloglucosidase 90 U/g) with a total reducing sugar of 22.78 ± 3.06 and 16.92 ± 2.06% (w/w), respectively. On the other hand, using the higher enzymes concentrations, no difference was observed between the two addition strategies, 58.9 ± 3.55 and 57.05 ± 2.33% (w/w) for the sequential and simultaneous, respectively. Both strategies didn’t present advantage, since the amyloglucosidase enzyme alone produced slightly higher results. Even thought, the obtained results showed successfully performed saccharification of microalgal biomass and clearly point to microalgae use for saccharification and subsequent bioethanol production.

Temperature and salinity changes can affect nutrient assimilation dynamics in primary producers. Green macroalgae use nitrate as a main source of nitrogen for their metabolism. Nitrate needs to be reduced by nitrate reductase, before amino acids synthesis. Our aims were to study the effect of temperature and salinity changes on nitrate reductase activity (NRA) in Ulva rigida and Enteromorpha clathrata, and to assess if this enzyme can be used as an environmental indicator for changes in such abiotic factors. The study of NRA was carried out using potassium nitrate as substrate and propanol as a membrane permeabilizer, letting the produced nitrite to exit the macroalgae cells into the assay medium, allowing its quantification through a colorimetric method. This procedure was carried out at five temperatures (10, 20, 30, 35 and 40 °C) and three salinities of the assay medium (0, 15 and 36 g/kg). Results show that both Ulva and Enteromorpha have maximum NRA at salinities of 36 g/kg, although nitrate reduction can occur in freshwater or brackish water, but at significantly lower rates. NRA varied significantly with temperature for both macroalgae, although Ulva showed maximum NRA at 30 °C, while NRA peaked at 35 °C in Enteromorpha. Likely adequate models were tentatively fitted to NRA-temperature data at different salinities. NRA is a suitable proxy of the effects of temperature and salinity changes on the ability of green macroalgae to uptake and metabolize nitrogen nutrients and can thus be the base for macroalgae proliferation models under climate change model scenarios.
