Accumulation of chemical elements and occurrence of microplastics in small pela...
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.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 l...
Year-round element quantification of a wide-ranging seabird and their relations...
Laranjeiro, Maria I.; Alves, Luís M.; Silva, Joana M. da; Pereira, Jorge M.; Norte, Ana C.; Paiva, Vitor H.; Lemos, Marco F.L.; Ramos, Jaime A.Multidisciplinary approaches are essential to diligently assess environmental health status of ecosystems. In this study, year-round chemical elements’ exposure and impacts were assessed on the wide-ranging Cory’s shearwater Calonectris borealis breeding in Berlenga Island, offshore Portugal, North Atlantic Ocean. The aim was to identify potential contamination and oxidative stress sources associated with troph...
Mercury levels in commercial mid-trophic level fishes along the Portuguese coas...
Silva, Joana M. da; Alves, Luís M.; Laranjeiro, Maria I.; Angélico, Maria M.; Norte, Ana C.; Lemos, Marco F.L.; Ramos, Jaime A.; Novais, Sara C.Sardines (Sardina pilchardus) and mackerels (Scomber spp. and Trachurus spp.) are amongst the most common fish caught along the Iberian coast for human consumption and, as mid-trophic level organisms, they constitute essential prey in the diet of several marine predators. Thus, the assessment of trophic ecology, contamination exposure, and stress responses in such organisms provides valuable information on the ...
