Preliminary deep-sea data analysis collected at Gloria seamount, Azores-Biscay ...
Tojeira, Inês; Pinto Ribeiro, Luísa; Rafael, Teresa; Albuquerque, Mónica; Simões, Maria; Calado, António; Afonso, Andreia; Ramos, Bruno; Souto, MiguelThe present study provides the first results of the exploratory research campaign to Gloria seamount (summit at 45.03°N, 15.54°W), a newly identified seamount in the NE Atlantic. New multibeam bathymetry and an 8 h remote operated vehicle footage and photography data were compiled and analyzed to give the first insights on the geological nature and benthic megafauna assemblages of Gloria seamount. Footage evide...
Marine spatial planning: a systematic literature review on its concepts, approa...
Rafael, Teresa; Cabral, Henrique; Mourato, João; Ferrão, JoãoMarine spatial planning (MSP) was developed as a process for managing the marine environment under the scenario of increased demand for space with different uses and economic activities. In the last decades, the research interest in MSP has been reflected by the growing number of published scientific articles on this subject. Nonetheless, a systematic scientific literature review on MSP is still lacking. In thi...
Assessment of contaminants in blue sharks from the Northeast Atlantic: Profiles...
Alves, Luís M F; Lemos, Marco F. L.; Moutinho, Ariana B; Ceia, Filipe R.; Muñoz-Arnanz, Juan; Jiménez, Begoña; Cabral, Henrique; Novais, Sara CChemical pollution is a major threat to marine ecosystems, and top predators such as most shark species are extremely vulnerable to being exposed and accumulating contaminants such as metals and persistent organic pollutants (POPs). This work aimed to study the degree, composition, and the sources of contamination in the blue shark (Prionace glauca) inhabiting the Northeast Atlantic, as well as the potential ri...
Genetic Structure of Meagre (Argyrosomus regius) in Portugal: Implications for ...
Almeida, Rita; Mateus, Catarina; Alves, Maria Judite; Marques, João; Pereira, Joana; Prista, Nuno; Cabral, Henrique; Almeida, Pedro; Bernardo, QuintellaThe meagre Argyrosomus regius (Asso, 1801) is a marine migratory species with a wide distribution range encompassing the north-eastern and central-eastern Atlantic Ocean, the Mediter ranean Sea, and the western Black Sea. A. regius is one of the largest overexploited sciaenids, being a valuable resource for aquaculture and fisheries along its distribution range. The Iberian Peninsula is considered an intermedia...

Evidence of contamination-associated damage in blue sharks (Prionace glauca) fr...
Alves, Luís M.F.; Moutinho, Ariana B.; Gómez, Luis J.; Oropesa, Ana L.; Muñoz-Arnanz, Juan; Jiménez, Begoña; Lemos, Marco F.L.; Fonseca, Vanessa F.Top predators such as most shark species are extremely vulnerable to amassing high concentrations of contaminants, but not much is known about the effects that the contaminant body burden imparts on these animals. Species like the blue shark (Prionace glauca) are very relevant in this regard, as they have high ecological and socioeconomic value, and have the potential to act as bioindicators of pollution. This ...
Elasmobranchs as bioindicators of pollution in the marine environment
Alves, Luís M.F.; Lemos, Marco F.L.; Cabral, Henrique; Novais, Sara C.Bioindicator species are increasingly valuable in environmental pollution monitoring, and elasmobranch species include many suitable candidates for that role. By measuring contaminants and employing biomarkers of effect in relevant elasmobranch species, scientists may gain important insights about the impacts of pollution in marine ecosystems. This review compiles biomarkers applied in elasmobranchs to assess t...
Does predation exacerbate the risk of endosymbiont loss in heat stressed hermat...
Madeira, Carolina; Dias, Marta; Ferreira, Ana; Gouveia, Raúl; Cabral, Henrique; Diniz, Mário S.; Vinagre, CatarinaOcean warming has been a major driver of coral reef bleaching and mass mortality. Coupled to other biotic pressures, corals' ability for acclimatization and adaptation may become compromised. Here, we tested the combined effects of warming scenarios (26, 30, and 32 degrees C) and predation (wound vs. no wound) in coral health condition (paleness, bleaching, and mortality), cellular stress responses (heat shock ...
Evidence of Genetic Segregation among Meagre (Argyrosomus regius) Atlantic Spaw...
Almeida, Rita; Mateus, Catarina S.; Alves, Maria Judite; Marques, João P.; Pereira, Joana; Prista, Nuno; Cabral, Henrique; Almeida, Pedro R.The meagre Argyrosomus regius, one of the largest sciaenidae in the world, is a valuable resource for fisheries and aquaculture. Despite its socioeconomic relevance, knowledge about population dynamics and wild stocks is still scarce, and conservation risks are associated with overexploitation. Two genetic distinct groups, one in the North Atlantic Ocean and one in the eastern Mediterranean Sea, were identified...
