- 1ª edição do festival nacional de gastronomia de Cabo VerdePublication . Varela, Zenaide Sanches; Almeida, Paulo Jorge SantosOs festivais gastronómicos de abrangência nacional, têm vindo a ser considerados uma das mais importantes estratégias de marketing aplicada aos destinos. Realizados anualmente, em vários países, devido à sua extrema importância na divulgação e valorização dos produtos tradicionais, estes eventos projetam a imagem de um determinado destino e por consequência, aumentam a sua notoriedade e capacidade competitiva. No que concerne ao destino Cabo Verde, este tipo de promoção tem vindo a “ganhar asas”, mas apenas numa dimensão regional ou local. O que se tem revelado insuficiente para mostrar a autenticidade e especificidade gastronómicas de cada ilha. Neste contexto, verificou-se a necessidade da aposta no Festival Nacional de Gastronomia do referido destino, com o intuito de provar a todos aqueles que o procuram, que o seu produto turístico não se resume apenas ao turismo sol e mar. Assim, a ideia foi apresentada às entidades responsáveis pelo Turismo, tendo sido muito bem acolhida, e constatou-se que há disponibilidade para abraçar com entusiasmo este projeto, reconhecendo a sua vital importância na divulgação do valioso património gastronómico de Cabo Verde.
- 5-years after-Life Berlengas: Conservation efforts and monitoring in Berlengas Archipelago (2019-2024). Project LIFE Berlengas. SPEA - Portuguese Society for the Study of BirdsPublication . Oliveira, Nuno; Almeida, Ana; Alonso, Hany; Bouça, Alexandra; Costa, M.; Crisóstomo, Paulo; Leandro, Sergio Miguel; Mendes, R. N.; Morais, L.; Mouga, Teresa; Mourato, E.; Nascimento, T; Paiva, V. H.; Silva , C. Pereira da; Andrade, JO pós-LIFE Berlengas teve início em 2019. Neste relatório são apresentadas as tarefas realizadas durante 2019-2024, nomeadamente, monitorização e conservação de aves marinhas, biossegurança, controlo de plantas invasoras e monitorização da flora. Os resultados alcançados em termos de investigação, voluntariado, apoio, visitação e ações de sensibilização são também apresentados. A informação recolhida anteriormente ao pós-LIFE foi compilada de forma a apresentar todas as séries temporais disponíveis. Em termos de aves marinhas reprodutoras, foram monitorizados os tamanhos populacionais, a produtividade, as taxas de sobrevivência individual, seguimento individual, a ocupação dos ninhos artificiais e outras atividades de conservação. As espécies-alvo foram o roque-de-castro Hydrobates castro, a cagarra Calonectris borealis, a galheta Gulosus aristotelis, a gaivota-d'asa-escura Larus fuscus, a gaivota-de-patas amarelas Larus michahellis e o airo Uria aalge. Foram testadas medidas de mitigação para reduzir a captura acidental de aves marinhas e a interação com as pesca durante 229 dias de pesca. As aves terrestres reprodutoras e migradoras foram monitorizadas através de sessões de anilhagem e observações no terreno. Das 72 espécies observadas nas ilhas, foram anilhadas 20 espécies distintas. As medidas de biossegurança foram monitorizadas ao longo de cada ano na ilha da Berlenga. Não foram detetados sinais de roedores nas armadilhas A24 ©GoodNature nem nas caixas-rateiras. Apesar dos cinco alertas da potencial presença de roedores emitidos. As Berlengas continuam livres de roedores. No entanto foi feita a observação de fezes frescas de coelho-bravo Oryctolagus cuniculus em maio de 2024. Anualmente em abril, a vegetação foi monitorizada através de 75 quadrados de 2x2m. A cobertura e diversidade da vegetação aumentou ao longo dos anos, com 2024 a atingir o maior número de espécies registadas - 80. Foi monitorizada uma área de exclusão de gaivota-de-patas-amarelas durante a primavera. Foram observadas diferenças significativas entre as subáreas, com maiores abundâncias de Armeria berlengensis na subárea de exclusão, quando comparada com a área de não exclusão. Os novos rebentos de chorão Carpobrotus edulis foram removidos das áreas intervencionadas no âmbito do LIFE Berlengas, o que resultou num esforço anual de monitorização de 466 pessoas*hora. Desde 2019, foram publicados 16 artigos em revistas científicas. Entre 2019 e 2024, 71 voluntários estiveram envolvidos nos trabalhos das Berlengas. A SPEA implementou 4 projetos para assegurar as tarefas do Pós-LIFE. A visitação na ilha da Berlenga foi monitorizada anualmente. As melhorias que decorreram incluíram a implementação da Capacidade de Carga Humana e a plataforma de acesso à ilha da Berlenga. A câmara "ninho ao vivo" esteve ativa ao longo de todo o período, transmitindo imagens em tempo real a partir de um ninho de cagarra e de um ninho de roque-de-castro, em alternado. Foram desenvolvidas diversas ações para sensibilização e de educação ambiental pela SPEA e ICNF. Tais atividades tiveram como público-alvo os visitantes da ilha da Berlenga, os pescadores de Peniche, grupos internacionais, operadores marítimo-turísticos, professores e alunos das escolas locais.

- ABI1 and PP2CA Phosphatases Are Negative Regulators of Snf1-Related Protein Kinase1 Signaling in ArabidopsisPublication . Rodrigues, Américo; Adamo, Mattia; Crozet, Pierre; Margalha, Leonor; Confraria, Ana; Martinho, Cláudia; Elias, Alexandre; Rabissi, Agnese; Lumbreras, Victoria; González-Guzmán, Miguel; Antoni, Regina; Rodriguez, Pedro L.; Baena-González, ElenaPlant survival under environmental stress requires the integration of multiple signaling pathways into a coordinated response, but the molecular mechanisms underlying this integration are poorly understood. Stress-derived energy deprivation activates the Snf1-related protein kinases1 (SnRK1s), triggering a vast transcriptional and metabolic reprogramming that restores homeostasis and promotes tolerance to adverse conditions. Here, we show that two clade A type 2C protein phosphatases (PP2Cs), established repressors of the abscisic acid (ABA) hormonal pathway, interact with the SnRK1 catalytic subunit causing its dephosphorylation and inactivation. Accordingly, SnRK1 repression is abrogated in double and quadruple pp2c knockout mutants, provoking, similarly to SnRK1 overexpression, sugar hypersensitivity during early seedling development. Reporter gene assays and SnRK1 target gene expression analyses further demonstrate that PP2C inhibition by ABA results in SnRK1 activation, promoting SnRK1 signaling during stress and once the energy deficit subsides. Consistent with this, SnRK1 and ABA induce largely overlapping transcriptional responses. Hence, the PP2C hub allows the coordinated activation of ABA and energy signaling, strengthening the stress response through the cooperation of two key and complementary pathways.
- Abóbora da Região Oeste: Desenvolvimento de um novo produto alimentar com desperdício zeroPublication . Leitão, Karinne Morais; Pinheiro , Maria Joaquina da Cunha; Silva , Susana Filipa de JesusEste estudo investigou o potencial da abóbora da Região Oeste como matéria-prima para a criação de produtos alimentares sustentáveis, com ênfase na produção de farinha de abóbora de desperdício zero. Foram avaliadas características físico-químicas, como teor de humidade, atividade de água (aw) e componentes bioativos, em três variedades de abóbora (Cucurbita spp.): Manteiga, Hokkaido e Menina, no estado fresco e após secagem a 60 °C durante aproximadamente 20 horas, até obtenção de peso constante. A análise comparativa entre o produto fresco e o seco incluiu atributos de qualidade como cor (CIELab), teor de humidade, atividade de água e componentes bioativos, nomeadamente capacidade antioxidante e teor de compostos fenólicos totais. Os resultados demonstraram que a farinha de abóbora apresenta elevada estabilidade, associada à reduzida atividade de água, favorecendo a preservação de fibras, vitaminas e compostos bioativos. Assim, a farinha de abóbora revelou potencial para aplicação em diversas formulações alimentares, incluindo produtos de pastelaria e/ ou panificação, atuando como ingrediente funcional e inovador. O estudo evidencia ainda o contributo da economia circular, ao promover a utilização integral do fruto: polpa, casca e sementes, reduzindo o desperdício alimentar, valorizando o perfil nutricional e reforçando a sustentabilidade industrial. Entre as limitações do estudo, destaca-se a necessidade de validação em escala industrial, bem como a realização de análises complementares, incluindo estudos microbiológicos, análise sensorial, avaliação da vida útil e aplicação de diferentes metodologias para determinação da capacidade antioxidante.
- Accessible Tourism in Russia: Recommendations for a Universal Design, Barrier-free EnvironmentPublication . Amineva, Inna; Almeida, Anabela Clemente Elias; Oliveira, Fernanda Maria FernandesRecently, barrier-free tourism has become increasingly important. The number of people with disabilities around the world is growing. Most of these people want and can travel. But not all countries and cities have a sufficiently adapted environment for comfortable movement. The purposes of this master’s thesis are to research accessible tourism in the cities of the Russian Federation, determine the problems that people with disabilities face in Russia during travel, understand how the lack of an available environment affects the desire to travel. The principles of universal design are also discussed in this work, and special attention is paid to how these principles should be followed in the tourism industry. In addition, define what changes will be the most effective in developing an accessible environment and will be able to lead to an increase in the number of disabled people as participants in tourism. This study is based on semi-structured interviews. The questions for the research have been prepared after an extensive analysis of the current state of the theory. The research was performed among people with disabilities who use wheelchairs or their caregivers. The experiences of twelve participants were evaluated. The analyses of the interviews identified several challenges that the participants were dealing with. These findings provided a clearer understanding of the problems currently being experienced by the study group. They also helped address a number of outstanding research questions. To sum up the findings of this research, the availability of an accessible environment is a crucial factor when choosing a holiday destination for people with disabilities and their caregivers. The developed accessible environment gives people with disabilities a sense of freedom, independence, and makes them equal members of society and motivates them to choose new places to travel. Thus, creating a barrier-free environment might play an important role in attracting new visitors and become a serious competitive advantage among tourism companies.
- Acclimation capability inferred by metabolic performance in two sea cucumber species from different latitudesPublication . Kühnhold, Holger; Novais, Sara C.; Alves, Luís M. F.; Kamyab, Elham; Lemos, Marco F. L.; Slater, Matthew J.; Kunzmann, AndreasThe notion that thermal specialists from tropical regions live closer to their temperature limits than temperate eurytherms, seems too generalized. Species specific differences in physiological and biochemical stress reactions are linked to key components of organism fitness, like metabolic capacity, which indicates that acclimation potential across latitudes might be highly diverse rather than simplistic. In this study the exposure of a tropical (Holothuria scabra) and a temperate (Holothuria forskali) sea cucumber species to identical cold- and warmacclimation stress was compared using the key metabolic parameters, respiration rate, enzyme activity (ETS, LDH, IDH), and energy reserve fractions (lipid, carbohydrate and protein). Results show much broader respiratory adjustments, as response to temperature change, in H. scabra (2–30 μgO2*gww−1 *h−1) compared to H. forskali (1.5–6.6 μgO2*gww−1 *h−1). Moreover, the tropical species showed clearly pronounced up and down regulation of metabolic enzymes and shifts in energy reserves, due to thermal acclimation, while the same metabolic indicators remained consistent in the temperate species. In summary, these findings indicate enhanced metabolic plasticity in H. scabra at the cost of elevated energy expenditures, which seems to favor the tropical stenotherm in terms of thermal acclimation capacity. The comparison of such holistic metabolic analyses between conspecifics and congeners, may help to predict the heterogeneous effects of global temperature changes across latitudinal gradients.
- Account for variation by field in publication: Bibliometric databases’ analysis in a Portuguese Higher Education InstitutionPublication . Malheiros, Cátia; Gomes, Conceição; Campos, Filipa; Eurico, SofiaThis study seeks to examine the variation by field in publication practices in a Portuguese Higher Education Institution (HEI), where both research in Social Sciences and in Hard Sciences is conducted. The intention is to raise the issue of the suitability of bibliometrics for the Professors/researchers’ evaluation considering their areas of research, as well as understanding the sort of use they make of these instruments. Different bibliometric Databases were managed to analyze the use given to them by all the researchers in this HEI and to find out the main differences in its use according to the researched field of study. These results might represent a valuable source of information for HEIs in the process of finding the balance between the different procedures and format for the evaluation of researchers, to identify their in/ability to proficiently use these tools and to study the suitability of each tool to different profiles.
- Accounting for dissimilarities in hospitality costs among Portuguese regionsPublication . Tourita, Íris; Gomes, Conceição; Lima Santos, Luís; Malheiros, CátiaHospitality industry is characterized by some specificities such as high fixed costs, labour intensive and intensive capital. All of these implies a unique cost structure that will be different from the other industries. A large share of operating costs in the hospitality industry is fixed costs, including labour costs. Those differences will imply a divergence in the use management accounting techniques so that manager decisions will be better. The hotel performance diverges according the location and the cost structure has got a great influence in the company’s performance. It is also known that competition influence the enterprises costs, and the hospitality competition is diverse among Portuguese regions. Therefore, it could be asked if the cost structure varies according to location of the hotel company. Data was collected on July 4, 2019, on the SABI platform and the sample is composed by 1808 hotel companies registered in Portugal with two economic activity codes (CAE), “55111 - Hotels with restaurant” and “55121 - Hotels without restaurant”. The cost structure was analysed in the 2010-2017 period through the costs presented in income statement. The findings provide current trends about hospitality industry cost structure and the evolution between 2010 and 2017. In Portugal, in general terms, supplies and external services have got the largest share of the cost structure. In addition, an inter-comparison region was made, which determined that cost structure is significantly different. In fact, supplies and external services, labour cost, cost of goods sold, and materials consumed, and depreciation have a different weight among the Portuguese regions.
- Accumulation of chemical elements and occurrence of microplastics in small pelagic fish from a neritic environmentPublication . Silva, Joana M. da; Alves, Luís M.F.; Laranjeiro, Maria I.; Bessa, Filipa; Silva, Andreia V.; Norte, Ana C.; Lemos, Marco F.L.; Ramos, Jaime A.; Novais, Sara C.; Ceia, Filipe R.The assessment of contaminant exposure in marine organisms often focuses on the most toxic chemical elements from upper trophic level species. Information on mid-trophic level species and particularly on potentially less harmful elements is lacking. Additionally, microplastics have been considered emergent contaminants in aquatic environments which have not been extensively studied in species from mid-trophic levels in food chains. This study aims to contribute to an overall assessment of environmental impacts of such chemicals in a community of small pelagic fish in the North Atlantic. The concentrations of 16 chemical elements, rarely simultaneously quantified (including minerals, trace elements and heavy metals), and the presence of microplastics were analysed in sardines (Sardina pilchardus) and mackerels (Scomber spp. and Trachurus trachurus) sampled along the Portuguese coast. Biochemical stress assessments and stable isotope analyses were also performed. The chemical element concentrations in S. pilchardus, T. trachurus, and Scomber spp. were relatively low and lower than the levels reported for the same species in the North Atlantic and adjacent areas. No clear relationships were found between chemical elements and oxidative damage in fish. However, the concentration of several chemical elements showed differences among species, being related with the species’ habitat use, trophic niches, and specific feeding strategies. The presence of plastic pieces in the stomachs of 29% of the sampled fishes is particularly concerning, as these small pelagic fish from mid-trophic levels compose a significant part of the diet of humans and other top predators. This study highlights the importance of multidisciplinary approaches focusing on the individual, including position data, stable isotopes, and oxidative stress biomarkers as complementary tools in contamination assessment of the marine mid-trophic levels in food chains.
