Combined effects of temperature rise and sodium lauryl sulfate in the Mediterra...
Freitas, Rosa; Arrigo, Federica; Coppola, Francesca; Meucci, Valentina; Battaglia, Federica; Soares, Amadeu M V M; Pretti, Carlo; Faggio, CaterinaPersonal care products (PCPs) are those compounds used daily (e.g., soaps, shampoos, deodorants, and toothpaste), explaining their frequent detection in aquatic systems. Still, scarce information is available on their effects on inhabiting wildlife. Among the most commonly used PCPs is the surfactant Sodium Lauryl Sulfate (SLS). The present study investigated the influence of temperature (CTL 17 ºC vs 22 ºC) on...
Obesogens beyond Vertebrates: Lipid Perturbation by Tributyltin in the Crustace...
Jordão, Rita; Casas, Josefina; Fabrias, Gemma; Campos, Bruno; Piña, Benjamín; Lemos, Marco; Soares, Amadeu M V M; Tauler, Romà; Barata, CarlosThe analysis of obesogenic effects in invertebrates is limited by our poor knowledge of the regulatory pathways of lipid metabolism. Recent data from the crustacean Daphnia magna points to three signaling hormonal pathways related to the molting and reproductive cycles [retinoic X receptor (RXR), juvenile hormone (JH), and ecdysone] as putative targets for exogenous obesogens. Objective: The present study addre...
Predation life history responses to increased temperature variability
Barbosa, Miguel; Pestana, Joâo; Soares, Amadeu M V MThe evolution of life history traits is regulated by energy expenditure, which is, in turn, governed by temperature. The forecasted increase in temperature variability is expected to impose greater stress to organisms, in turn influencing the balance of energy expenditure and consequently life history responses. Here we examine how increased temperature variability affects life history responses to predation. I...
