Differential tissue accumulation in the invasive Manila clam, Ruditapes philipp...
Figueiredo, Cátia; Grilo, Tiago F.; Lopes, Ana Rita; Lopes, Clara; Brito, Pedro; Caetano, Miguel; Raimundo, JoanaAmong the environmental emerging concern rare earth elements, lanthanum (La) is one of the most common and reactive. Lanthanum is widely used in numerous modern technologies and applications, and its intense usage results in increasing discharges into the environment, with potentially deleterious consequences to earthlings. Therefore, we exposed the important food resource and powerful monitoring tool Manila cl...
Impaired antioxidant defenses and DNA damage in the European glass eel (Anguill...
Lopes, Ana Rita; Figueiredo, Cátia; Sampaio, Eduardo; Diniz, Mário; Rosa, Rui; Grilo, Tiago F.The European eel (Anguilla anguilla) has attracted scientific inquiry for centuries due to its singular biological traits. Within the European Union, glass eel fisheries have declined sharply since 1980, from up to 2000 t (t) to 62.2 t in 2018, placing wild populations under higher risk of extinction. Among the major causes of glass eels collapse, climate change has become a growing worldwide issue, specificall...
Warming enhances lanthanum accumulation and toxicity promoting cellular damage ...
Figueiredo, Cátia; Raimundo, Joana; Lopes, Ana Rita; Lopes, Clara; Rosa, Nuno; Brito, Pedro; Diniz, Mário; CAETANO, MIGUEL; Grilo, Tiago F.Cumulative and continuing human emissions of greenhouse gases to the atmosphere are causing ocean warming. Rising temperature is a major threat to aquatic organisms and may affect physiological responses, such as acid-base balance, often compromising species fitness and survival. It is also expected that warming may influence the availability and toxicological effects of pollutants, including Rare Earth Element...
Latitudinal Patterns in European Seagrass Carbon Reserves: Influence of Seasona...
Soissons, Laura M.; Haanstra, Eeke P; van Katwijk, Marieke M.; Asmus, Ragnhild; Auby, Isabelle; Barillé, Laurent; Brun, Fernando G.Seagrass meadows form highly productive and valuable ecosystems in the marine environment. Throughout the year, seagrass meadows are exposed to abiotic and biotic variations linked to (i) seasonal fluctuations, (ii) short-term stress events such as, e.g., local nutrient enrichment, and (iii) small-scale disturbances such as, e.g., biomass removal by grazing. We hypothesized that short-term stress events and sma...
Kinetics of mercury bioaccumulation in the polychaete Hediste diversicolor and ...
Cardoso, Patricia G.; Pereira, Eduarda; Grilo, Tiago F.; Duarte, Armando C.; Pardal, Miguel A.Mercury bioaccumulation kinetics of two important macrobenthic species, the polychaete Hediste diversicolor and the bivalve Scrobicularia plana, were evaluated following a dietary pathway (i.e. contaminated algae), through a mesocosm laboratory experiment. Both studied species presented a similar model of Hg bioaccumulation kinetics, a linear pattern of accumulation through time being the mercury accumulation i...
