The mucus covers the fish's body, working as a protective barrier. Besides physical protection, mucus provides molecules that protect the fish from pathogens damaging 1,2. These include antimicrobial peptides secreted in the mucus, which play an essential role in defense against microbial pathogens since these belong to the innate immune system2,3. In this study, two adult Halobatrachus didactylus individuals were captured from the wild in Sesimbra. Then, mucus collection was performed by scraping the dorsal-lateral body of the fish with a sponge. Our objective was the identification of new peptides with bioactive potential in mucus samples by chromatography analysis. Size exclusion highperformance liquid chromatography (SE-HPLC) analysis performed on mucus samples from the two individuals revealed a similar profile with an intense highlight peak which resulted in a distribution of about 775 Dalton. With interest in that peak, the two mucus samples were pooled for fractionation by SEC. The resulting fraction was analyzed by liquid chromatography-tandem mass spectrometry (LCMS/MS) to identify the most probable peptide sequences. Identification from databases did not provide reliable results, indicating a lack of information on the matrix analyzed. We resorted to de novo sequencing with good results using PEAKS Studio software. Five identified peptides were selected according to their bioactivities predicted in silico. Furthermore, the five identified peptides were synthesized, and the molecular size was validated by SE-HPLC analysis. Overall, this chromatographic approach enabled the identification of promising peptides, which bioactivities will be evaluated in vitro in future work.

We combine consistently dated benthic carbon isotopic records distributed over the entire Atlantic Ocean with numerical simulations performed by a glacial configuration of the Norwegian Earth System Model with active ocean biogeochemistry, in order to interpret the observed Cibicides δ13C changes at the stadial-interstadial transition corresponding to the end of Heinrich Stadial 4 (HS4) in terms of ocean circulation and remineralization changes. We show that the marked increase in Cibicides δ13C observed at the end of HS4 between ~2000 and 4200 m in the Atlantic can be explained by changes in nutrient concentrations as simulated by the model in response to the halting of freshwater input in the high latitude glacial North Atlantic. Our model results show that this Cibicides δ13C signal is associated with changes in the ratio of southern-sourced (SSW) versus northern-sourced (NSW) water masses at the core sites, whereby SSW is replaced by NSW as a consequence of the resumption of deep water formation in the northern North Atlantic and Nordic Seas after the freshwater input is halted. Our results further suggest that the contribution of ocean circulation changes to this signal increases from ~40 % at 2000 m to ~80 % at 4000 m. Below ~4200 m, the model shows little ocean circulation change but an increase in remineralization across the transition marking the end of HS4. The simulated lower remineralization during stadials than interstadials is particularly pronounced in deep subantarctic sites, in agreement with the decrease in the export production of carbon to the deep Southern Ocean during stadials found in previous studies.

Triple threat processes and/or other forcings can lead to changes in the ocean happening fast and abruptly. These changes, referred to as “tipping points”, are critical thresholds in a marine system that, when exceeded, can lead to a significant change in the state of the system, which often can be irreversible.

Tropospheric ozone (O3) concentrations depend on a combination of hemispheric, regional, and local-scale processes. Estimates of how much O3 is produced locally vs. transported from further afield are essential in air quality management and regulatory policies. Here, a tagged-ozone mechanism within the Weather Research and Forecasting model coupled with chemistry (WRF-Chem) is used to quantify the contributions to surface O3 in the UK from anthropogenic nitrogen oxide (NOx) emissions from inside and outside the UK during May–August 2015. The contribution of the different source regions to three regulatory O3 metrics is also examined. It is shown that model simulations predict the concentration and spatial distribution of surface O3 with a domain-wide mean bias of −3.7 ppbv. Anthropogenic NOx emissions from the UK and Europe account for 13 % and 16 %, respectively, of the monthly mean surface O3 in the UK, as the majority (71 %) of O3 originates from the hemispheric background. Hemispheric O3 contributes the most to concentrations in the north and the west of the UK with peaks in May, whereas European and UK contributions are most significant in the east, south-east, and London, i.e. the UK's most populated areas, intensifying towards June and July. Moreover, O3 from European sources is generally transported to the UK rather than produced in situ. It is demonstrated that more stringent emission controls over continental Europe, particularly in western Europe, would be necessary to improve the health-related metric MDA8 O3 above 50 and 60 ppbv. Emission controls over larger areas, such as the Northern Hemisphere, are instead required to lessen the impacts on ecosystems as quantified by the AOT40 metric.

A cidade é um produto complexo que combina recursos físicos e aspetos culturais, históricos, sociais e económicos que influenciam na formação da sua identidade. Dessa forma, a identidade de uma cidade é o seu ADN: uma combinação distinta e herdada de bens, história, características e cultura que a define interna e externamente e tem o poder de unificar pessoas e lugares. Como a identidade é a base sobre a qual a imagem de uma cidade é criada, é de grande importância considerar como as cidades constroem e desenvolvem a sua identidade. A cidade de Matosinhos apresenta-se como objeto de estudo, destacando as características únicas da cidade que definem a sua identidade cultural. A ligação profunda ao mar continua a ser a característica mais importante que define a identidade de Matosinhos. É possível notar esta relação em vários aspetos, uma vez que Matosinhos tem uma das melhores infraestruturas portuárias do país (o porto de Leixões), uma gastronomia rica em sabores do mar (um polo de atração turística), um rico património com monumentos e esculturas dedicadas ao mar, bem como importantes tradições e celebrações que contribuem para preservar o espírito da sua comunidade. Esta relação é também evidente nas inúmeras atividades económicas que dependem do mar, bem como nas horas de lazer desfrutadas pelos locais e turistas que visitam as praias e o mar para tirar proveito desta caraterística especial de Matosinhos. Da mesma forma que o mar contribui para definir a identidade de Matosinhos, revela também como Matosinhos afirma a sua posição para o desenvolvimento de uma economia azul sustentável. The city is a complex product that combines physical resources as well as cultural, historical, social, and economic aspects that influence the formation of its identity. In this way, the identity of a city is its DNA: a distinct, inherited combination of assets, history, characteristics, and culture that defines it internally and externally and has the power to unify people and place. Because identity is the foundation upon which a city's image is created, it is vital to consider how cities build and develop their identity. The city of Matosinhos will be the object of study, highlighting the city's unique characteristics that define its cultural identity. The deep connection to the sea remains the most important feature that characterises Matosinhos' identity. It is possible to note this relationship in several aspects since Matosinhos has one of the best port infrastructures in the country (the port of Leixões), a gastronomy rich in sea flavours (a pole of tourist attraction), a rich heritage with many monuments and sculptures dedicated to the sea, as well as important traditions and celebrations that contribute to preserving the spirit of its community. This relationship is also evident in the numerous economic activities that rely on the sea, as well as the hours of relaxation enjoyed by locals and tourists who visit the beaches and the sea to take advantage of this Matosinhos special feature. In the same way that the sea contributes to define the identity of Matosinhos, it also reveals how Matosinhos affirms its position for the development of a sustainable blue economy.
