Protein analysis and gene expression indicate differential vulnerability of Ibe...
Jesus, Tiago Filipe; Moreno, João M.; Repolho, T.; Athanasiadis, Alekos; Rosa, Rui; Almeida-Val, Vera Maria Fonseca; Coelho, Maria ManuelaCurrent knowledge on the biological responses of freshwater fish under projected scenarios of climate change remains limited. Here, we examine differences in the protein configuration of two endemic Iberian freshwater fish species, Squalius carolitertii and the critically endangered S. torgalensis that inhabit in the Atlantic-type northern and in the Mediterranean-type southwestern regions, respectively. We per...
Negative synergistic impacts of ocean warming and acidification on the survival...
Araújo, J.E.; Madeira, D.; Vitorino, R.; Repolho, T.; Rosa, R.; Diniz, M.Global change is impacting aquatic ecosystems, with high risks for food production. However, the molecular underpinnings of organismal tolerance to both ocean warming and acidification are largely unknown. Here we tested the effect of warming and acidification in a 42-day experiment on a commercial temperate fish, the gilt-head seabream Sparus aurata. Juvenile fish were exposed to control (C 18 °C pH 8), ocean ...
Avaliação da toxicidade das lamas de cal sobre o ouriço-do-mar Paracentrotus li...
Gaspar, N.; Gago, João; Repolho, T.; Luís, O.Através da utilização do ouriço-do-mar Paracentrotus lividus como bioindicador, neste estudo avaliou-se a potencialidade de utilização de um resíduo das indústrias do papel, as lamas de cal, em duas vertentes. A primeira consistia em aproveitar a característica alcalina das lamas de cal como redutiva da crescente acidificação dos oceanos. Nos bioensaios realizados obteve-se um aumento significativo na percentag...
