Progressive acclimation alters interaction between salinity and temperature in ...
Loureiro, Cláudia; Cuco, Ana P.; Claro, Maria Teresa; Santos, Joana I.; Pedrosa, M. Arminda; Gonçalves, Fernando; Castro, Bruno B.Environmental stressors rarely act in isolation, giving rise to interacting environmental change scenarios. However, the impacts of such interactions on natural populations must consider the ability of organisms to adapt to environmental changes. The phenotypic adaptability of a Daphnia galeata clone to temperature rise and salinisation was investigated in this study, by evaluating its halotolerance at two diff...

Can physiological endpoints improve the sensitivity of assays with plants in th...
Gavina, Ana; Antunes, Sara C.; Pinto, Glória; Claro, Maria Teresa; Santos, Conceição; Gonçalves, Fernando; Pereira, RuthSite-specific risk assessment of contaminated areas indicates prior areas for intervention, and provides helpful information for risk managers. This study was conducted in the Ervedosa mine area (Bragança, Portugal), where both underground and open pit exploration of tin and arsenic minerals were performed for about one century (1857-1969). We aimed at obtaining ecotoxicological information with terrestrial and...
Genetic variability in the tolerance of natural populations of Simocephalus vet...
Loureiro, Cláudia; Castro, Bruno B.; Claro, Maria Teresa; Alves, Artur; Arminda Pedrosa, M.; Gonçalves, FernandoUsing several clonal lineages of Simocephalus vetulus (Cladocera, Daphniidae) as a random sample, we investigated the genetic component of the halotolerance of one brackish and two freshwater populations of this littoral filter feeder. We hypothesized that genotypes from the brackish population were more tolerant than freshwater ones, via adaptation to local environmental conditions. Clonal identity was establis...
“Impressões digitais moleculares”: um caso de estudo com populações naturais de...
Claro, Maria Teresa; Castro, Bruno B.; Alves, Artur; Correia, António; Loureiro, Cláudia; Gonçalves, FernandoOs dafnídeos pertencem ao zooplâncton de água doce e são organismos-modelo importantes em diversas áreas como limnologia, ecotoxicologia, genética ecológica e, recentemente, em genómica. Contudo, as suas relações filogenéticas e a sua taxonomia são ainda bastante controversas, sendo a identificação destes organismos dificultada pela elevada plasticidade fenotípica que apresentam e a existência de fluxo de genes...
