Interannual variability in early life phenology is driven by climate and oceani...

Vaz, Ana; Primo, Ana Lígia; Crespo, Daniel; Pardal, Miguel Ângelo; Martinho, Filipe

Early life phenology is a crucial factor for population dynamics in a climate change scenario. As such, understanding how the early life cycle of marine fishes is influenced by key oceanic and climate drivers is of chief importance for sustainable fisheries. This study documents interannual changes in early life phenology of two commercial flatfishes: European flounder (Platichthys flesus) and common sole (Sole...


The H9c2(2-1) cell-based sulforhodamine B assay is a non-animal alternative to ...

Rodrigues, Elsa T.; Pereira, Eduarda; Oliveira, Paulo J.; Pardal, Miguel Ângelo

The present study validates the potential of the in vitro H9c2(2-1) cell-based sulforhodamine B (SRB) assay to evaluate the temporal variability of wastewater quality. The impact of effluent disposal on water quality and the efficiency of the wastewater treatment process were also assessed. To correlate standard analytical method results with in vitro results, a total of 16 physicochemical parameters, such as n...


Implications of Warming on the Morphometric and Reproductive Traits of the Gree...

Monteiro, João N.; Bueno-Pardo, Juan; Pinto, Miguel; Pardal, Miguel Ângelo; Martinho, Filipe; Leitão, Francisco

Understanding the relationship between environmental temperature and the biological traits of organisms is fundamental to inferring the potential impacts of climate change. In the case of marine poikilotherm species, seawater temperature is one of the main driving forces of biological processes, with consequences at higher levels of organization such as population and ecosystem. In this study, we analysed diffe...


Seasonal characterization of mercury contamination along the Portuguese coast: ...

Cardoso, Patrícia Gonçalves; Morais, Hugo; Crespo, Daniel; Tavares, Daniela; Pereira, Eduarda; Pardal, Miguel Ângelo

A seasonal characterization of mercury (Hg) accumulation in three different estuaries along the Portuguese coast (i.e. Ria de Aveiro, Tagus estuary and Ria Formosa) was done. For that, it was evaluated: (1) Hg concentrations in abiotic (water) and biotic matrices (flora and fauna); (2) the risk of consumption of local seafood species (e.g. bivalves) to human health; and (3) the environmental risk to Hg exposure...


Surf zone zooplankton communities from the west coast of the Iberian Peninsula:...

Guerreiro, Milene Alexandra; Marques, Sónia Cotrim; Martinho, Filipe; Azeiteiro, Ulisses Miranda; Pardal, Miguel Ângelo; Primo, Ana Lígia

Studies on surf zone zooplankton biodiversity and population dynamics processes remain scarce in comparison to other coastal areas. In this work, we analysed the seasonal (winter/summer) variability of the surf zone zooplankton assemblage structure and copepod biomass of distinct areas with different substrate types (sandy beaches/rocky shores) at the west coast of the Iberian Peninsula (Portugal). Cypris of Ci...

Viver do mar: caracterização socioeconómica das comunidades piscatórias de arte...

Alves, Fátima; Casaleiro, Paula; Valentim, Cristina Sá; Neto, Jorge; Castro, Paula; Pardal, Miguel Ângelo

Este artigo visa caracterizar a pesca com arte xávega do ponto de vista socioeconómico. A arte xávega é um método artesanal de pesca praticado em Portugal desde o século XV, tendo conseguido sobreviver até aos dias de hoje. A pesquisa foi feita com recurso a um inquérito por questionário aplicado em 2018 a comunidades piscatórias da arte xávega, em praias das regiões norte, centro e sul de Portugal continental....


Meta-analysis of multidecadal biodiversity trends in Europe

Pilotto, Francesca; Kühn, Ingolf; Adrian, Rita; Alber, Renate; Alignier, Audrey; Andrews, Christopher; Bäck, Jaana; Barbaro, Luc; Beaumont, Deborah

Local biodiversity trends over time are likely to be decoupled from global trends, as local processes may compensate or counteract global change. We analyze 161 long-term biological time series (15-91 years) collected across Europe, using a comprehensive dataset comprising ~6,200 marine, freshwater and terrestrial taxa. We test whether (i) local long-term biodiversity trends are consistent among biogeoregions, ...


Uptake of enrofloxacin from seawater to the macroalgae Ulva and its use in IMTA...

Rosa, João; Leston, Sara; Crespo, Daniel; Freitas, Andreia; Pouca, Ana Sofia Vila; Barbosa, Jorge; Lemos, Marco F.L.; Pardal, Miguel Ângelo

Integrated multi-trophic aquaculture systems can minimize the environmental impacts of aquaculture, while delivering economical benefits. However, the use of extractive species such as seaweeds can accumulate pharmaceuticals commonly used in these systems. Therefore, this work evaluated the exposure of the seaweed Ulva to enrofloxacin (ENR), a vastly used antimicrobial in aquaculture, at two dosages (C1, 7.5 μg...

Integrated multitrophic aquaculture systems: potential risks for food safety

Rosa, João; Lemos, Marco F.L.; Crespo, Daniel; Nunes, Margarida; Freitas, Andreia; Ramos, Fernando; Pardal, Miguel Ângelo; Leston, Sara

Background: The demand for fish and fish products is now higher than ever. However, several problems such as nutrient loading or excessive use of resources can be associated with the intensification of aquaculture systems. Integrated multitrophic aquaculture systems (IMTAs) refer to the co-culture of different species belonging to different trophic levels, and offer a sustainable approach to aquaculture develop...

Tissue depletion of five antibiotic residues in farmed European seabass (Dicent...

Rosa, João; Leston, Sara; Freitas, Andreia; Barbosa, Jorge; Rema, Paulo; Dias, Jorge; Lemos, Marco F. L.; Pardal, Miguel Ângelo; Ramos, Fernando

Concerns about antibiotic use led to stricter legislations and overall better practices in aquaculture production. However, depletion time periods in tissues vary greatly with different antimicrobials, fish species, or experimental setup. In the present work, five drugs (sulfadiazine (SDZ), trimethoprim (TRI), flumequine (FLU), oxolinic acid (OXO), and oxytetracycline (OTC)) were incorporated into medicated fee...
