Sea warming affects bream (Sparus aurata) tissues and stress proteins (HSP70)
Madeira, D.; Vinagre, R.; Costa, Pedro M.; Caeiro, Sandra; Galésio, M.; Santos, H. M.; Nunez, C.; Oliveira, E.; Castro, L.; Pere, I.; Lodeiro, C.The aim of the present study is to assess the stress response of a marine fish, sea bream (Sparus aurata) exposed to increasing water temperature and different water acidity (alone or in combination). Here we present preliminary data on temperature effects on S. aurata at a cellular and molecular level. In addition, tissue samples from muscle, livers, gills and intestine are examined to evaluate any alterations...
HERA - Environmental Risk Assessment of a contaminated estuarine environment: a...
Martinho, Ana Paula; Rodrigo, Ana; Vicente, Ana; Machado, Ausenda; Dias, Carlos Matias; Guiomar, Carla Sofia; Gonçalves, Cátia; Paixão, EleonoraSado River estuary is located in the west coast of Portugal. Previous environmental studies identified industrial contamination, non-point anthropogenic sources and contamination coming from the river, all promoting accumulation of polluted sediments with known impacts on the ecological system. Surrounding human populations have intense economic fishery activities. Together with agriculture, estuary fishing pro...
Histological biomarkers in liver and gills of juvenile Solea senegalensis exposed
Costa, Pedro M.; Diniz, Mário S.; Caeiro, Sandra; Lobo, Jorge; Martins, Marta; Ferreira, Ana M.; Caetano, Miguel; Vale, Carlos; DelValls, ÁngelYoung juvenile Solea senegalensis were exposed to three sediments with distinct contamination profiles collected from a Portuguese estuary subjected to anthropogenic sources of contamination (the Sado estuary, western Portugal). Sedimentswere surveyed formetals (cadmium, chromium, copper, nickel, lead and zinc), ametalloid (arsenic) and organic contaminants (polycyclic aromatic hydrocarbons, polychlorinated bip...
Biochemical endpoints on juvenile Solea senegalensis exposed
Costa, Pedro M.; Caeiro, Sandra; Diniz, Mário S.; Lobo, Jorge; Martins, Marta; Ferreira, Ana M.; Caetano, Miguel; Vale, Carlos; DelValls, ÁngelJuvenile Solea senegalensis were exposed to fresh sediments from three stations of the Sado estuary (Portugal) in 28-day laboratory assays. Sediments revealed distinct levels of total organic matter, fine fraction, redox potential, trace elements (arsenic, cadmium, chromium, copper, nickel, lead and zinc) and organic contaminants (polycyclic aromatic hydrocarbons, polychlorinated biphenyls and a pesticide: dich...
