    Daphnia magna bioassays to detect novel eco-toxicological effects of prioritary and emergent contaminants 

    Campos, Bruno (Data de defensa: 2014-01-10)

    There is increasing evidence that the presence of many emerging pollutants in aquatic ecosystems may have detrimental effects on aquatic biota. Of special concern are those emerging pollutants that may act as putative ...

    Distribució i caracterització de les proteïnes espermàtiques bàsiques a peixos, agnats i procordats 

    Saperas Plana, Núria (Data de defensa: 1992-12-17)

    En aquest treball es caracteritzen les proteïnes espermàtiques bàsiques (PEB) que condensen el DNA de l'espermatozoide de diferents grups de deuteròstoms, tant procordats (tunicats o urocordats i cefalocordats) com vertebrats ...

    Distribution and partitioning of organic pollutants and effects in coastal birds 

    Vicente de Bobes, Joana (Data de defensa: 2013-11-14)

    Coastal areas are very susceptible to contamination due to the interaction of marine and anthropogenic processes. Persistent Organic Pollutants (POPs) are organic compounds very resistent to photolysis and chemical and ...

    Optical propertiers of the dissolved organic matter as tracers of microbiological and geochemical processes in marine ecosystems 

    Romera Castillo, Cristina (Data de defensa: 2011-10-07)

    Oceans store 685 Pg of organic carbon of which 662 Pg are in a dissolved form. The diversity of compounds that make up the dissolved organic matter (DOM) pool and the low concentration of each compound make the chemical ...

    Sediment dynamics and associated heavy metals in small river-and wave-dominated inner shelf (Barcelona city, Nw Mediterranean) 

    López Fernández, Laura (Data de defensa: 2013-10-24)

    Wave storms and river inputs have been found to be the dominant forcing mechanism of sediment transport in continental shelves dominated by medium to large rivers around the world (e.g. Drake and Cacchione, 1985; Sherwood ...
