Early life stage mechanisms of an active fish species to cope with ocean warmin...
Lima, André R.A.; Booms, Emily M.; Lopes, Ana Rita; Martins-Cardoso, Sara; Novais, Sara C; Lemos, Marco F.L.; Ribeiro, Laura; Castanho, SaraOcean’s characteristics are rapidly changing, modifying environmental suitability for early life stages of fish. We assessed whether the chronic effects of warming (24 ◦C) and hypoxia (<2–2.5 mg L− 1 ) will be amplified by the combination of these stressors on mortality, growth, behaviour, metabolism and oxidative stress of early stages of the white seabream Diplodus sargus. Combined warming and hypoxia synergi...
Integrated behavioural and physiological responses of sand smelt larvae to the ...
Lima, André R.A.; Lopes, Ana Rita; Martins-Cardoso, Sara; Moutinho, Ariana B.; Lemos, Marco F.L.; Novais, Sara C; Faria, Ana M.Forecasts indicate that rising temperatures towards the future and the expansion of dead zones will change environmental suitability for fish early stages. Therefore, we assessed the chronic effects of warming (26 ◦C), hypoxia (<2–2.5 mg L− 1 ) or their combination on mortality rate, growth, behaviour, energy metabolism and oxidative stress using Atherina presbyter larvae as a model species. There were no diffe...
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...
Impact of anthropogenic noise on the survival and development of meagre (Argyro...
Trabulo, Rita; Amorim, Clara; Fonseca, Paulo J.; Vieira, Manuel; Matos, André B.; Marin-Cudraz, Thibaut; Lemos, Marco F.L.; Moutinho, Ariana B.The growth of human populations has been driving an unprecedent and widespread increase in marine traffic, posing a real threat to marine biodiversity. Even though we are now aware of the negative effects of shipping noise exposure on fish, information about the impact on their early life stages continues to lack. Meagre (Argyrosomus regius) is a vocal fish that uses estuaries with high levels of anthropogenic ...
Boat noise impacts Lusitanian toadfish breeding males and reproductive outcome
Amorim, Maria Clara P; Vieira, Manuel; Meireles, Gabriela; Novais, Sara C; Lemos, Marco F.L.; Modesto, Teresa; Alves, Daniel; Zuazu, Ana; Lopes, Ana F.Anthropogenic noise is a growing threat to marine organisms, including fish. Yet very few studies have addressed the impact of anthropogenic noise on fish reproduction, especially in situ. In this study, we investigated the impacts of boat noise exposure in the reproductive success of wild Lusitanian toadfish (Halobatrachus didactylus), a species that relies on advertisement calls for mate attraction, using beh...
Effects of Propranolol on Growth, Lipids and Energy Metabolism and Oxidative St...
Duarte, Bernardo; Feijão, Eduardo; Cruz de Carvalho, Ricardo; Duarte, Irina A; Silva, Marisa; Matos, Ana Rita; Cabrita, Maria Teresa; Novais, Sara CPresent demographic trends suggest a rise in the contributions of human pharmaceuticals into coastal ecosystems, underpinning an increasing demand to evaluate the ecotoxicological effects and implications of drug residues in marine risk assessments. Propranolol, a non-selective β-adrenoceptor blocker, is used worldwide to treat high blood pressure conditions and other related cardiovascular conditions. Although...
From laboratory to the field: Validating molecular markers of effect in Folsomi...
Simões, Tiago; Novais, Sara C; Luz, Tiago Natal da; Renaud, Mathieu; Leston, Sara; Ramos, Fernando; Römbke, Jörg; Roelofs, Dick; van Straalen, Nico MUnder controlled laboratory conditions, toxicity data tend to be less variable than in more realistic in-field studies and responses may thus differ from those in the natural environment, creating uncertainty. The validation of data under environmental conditions is therefore a major asset in environmental risk assessment of chemicals. The present study aimed to validate the mode of action of a commercial fungi...
An integrative omics approach to unravel toxicity mechanisms of environmental c...
Simões, Tiago; Novais, Sara C; Luz, Tiago Natal da; Devreese, Bart; de Boer, Tjalf; Roelofs, Dick; Sousa, José P.; van Straalen, Nico MThe use of integrative molecular approaches can aid in a comprehensive understanding of the effects of toxicants at different levels of biological organization, also supporting risk assessment. The present study aims to unravel the toxicity mechanisms of a widely used herbicide to the arthropod Folsomia candida exposed in a natural soil, by linking effects on reproduction, proteomics and genome-wide gene expres...
