Impacts of the combined exposure to seawater acidification and Arsenic on the p...
Moreira, Anthony; Figueira, Etelvina; Mestre, Nélia C.; Schrama, Denise; Soares, Amadeu M. V. M.; Freitas, Rosa; Bebianno, Maria JoãoProteomic analysis was performed to compare the effects of Arsenic (As), seawater acidification (Low pH) and the combination of both stressors (Low pH+As) on Crassostrea angulata and Crassostrea gigas juveniles in the context of global environmental change. This study aimed to elucidate if two closely related Crassostrea species respond similarly to these environmental stressors, considering both single and combi...
Potential Mitigation and Restoration Actions in Ecosystems Impacted by Seabed M...
Cuvelier, Daphne; Gollner, Sabine; Jones, Daniel O. B.; Kaiser, Stefanie; Arbizu, Pedro Martínez; Menzel, Lena; Mestre, Nélia C.; Morato, TelmoMining impacts will affect local populations to different degrees. Impacts range from removal of habitats and possible energy sources to pollution and smaller-scale alterations in local habitats that, depending on the degree of disturbance, can lead to extinction of local communities. While there is a shortage or even lack of studies investigating impacts that resemble those caused by actual mining activity, th...
Exploitation of deep-sea resources: the urgent need to understand the role of h...
Mestre, Nélia C.; Calado, Ricardo; Soares, Amadeu M. V. M.The advent of industrial activities in the deep sea will inevitably expose deep-sea organisms to potentially toxic compounds. Although international regulations require environmental risk assessment prior to exploitation activities, toxicity tests remain focused on shallow-water model species. Moreover, current tests overlook potential synergies that may arise from the interaction of chemicals with natural stre...
