    Modelling the relationships of medium and long-term variations of the anchovy and sardine catches in the Catalan Sea (NW Mediterranean) with the environmental drivers 

    Quattrocchi, Federico (Date of defense: 2017-10-24)

    The understanding of the driving forces involved in the abundance fluctuation of fish populations is an important requirement for conservation and management, especially in the context of environmental changes. In the North ...

    New observational approaches for optically complex waters based on high-resolution transmissometry 

    Ramírez Pérez, Marta (Date of defense: 2017-06-09)

    There is a growing concern for protection and conservation of coastal ecosystems, which require a proper understanding of ecosystem dynamics and the ability to detect and predict changes in the ecosystem state. For this ...

    Nuevas aproximaciones toxicológicas para la detección de disruptores endocrinos y lipídicos en ecosistemas mediterráneos y sistemas celulares 

    Blanco Rubio, María (Date of defense: 2018-03-20)

    Chemical compounds derived from human activities continuously reach aquatic systems, where they are available to the organisms that inhabit them. Traditionally, environmental risk assessment has been based on the chemical ...

    Opening the black box of coastal inshore waters in the NW Mediterranean Sea : environmental quality tools and assessment 

    Flo Arcas, Eva (Date of defense: 2017-11-20)

    Coastal inshore waters (CIW) are defined as the area of coastal waters between 0 and 200 m from the shoreline. They only represent < 1% of coastal waters, even though they are of main ecological, social, and economic ...

    Optimización de la reología de componentes fotocatalíticos para aplicaciones avanzadas en elementos de fachada 

    Elkoro Ugarteburu, Ander (Date of defense: 2018-10-26)

    This thesis discusses the development of a new methodology for 3D printing of TiO2 nanoparticles and its applications in air purification and hydrogen production. A dosage has been obtained that allows 3D printing by DIW ...

    Productos de cuidado personal en el medio ambiente : presencia, destino y efectos 

    Molins Delgado, Daniel (Date of defense: 2017-12-01)

    In this PhD. Thesis the results of eleven studies about the presence, distribution, and effects of personal care products (PCPs) in the environment are presented with the intention of giving a consolidated vision and to ...

    Saharan dust deposition effects on production in the Mediterranean Sea 

    Gallisai, Rachelle (Date of defense: 2016-11-04)

    The potential capacity of fertilization of surface oceans by atmospheric deposition is of scientific interest. This is especially true in the oligotrophic Mediterranean Sea. Its surface waters are extremely poor in nutrients ...

    Seawater intrusion, transition zone dynamics and reactive mixing : example of Argentona coastal alluvial aquifer 

    Goyetche, Tybaud (Date of defense: 2021-07-19)

    Freshwater quality and availability in coastal areas are affected by seawater intrusion into coastal aquifers. While coastal water quality and coastal ecosystems can be significantly affected by pollutants discharged into ...

    The structure and dynamics of complex microbe-host interaction networks 

    Björk, Johannes (Date of defense: 2016-06-03)

    Microbes form intricate and intimate relationships with most animals and plants, many of which are crucial for host development, health and functioning. Microbe--host symbiotic associations are poorly explored in comparison ...

    Study of near field processes involved in the oxidative dissolution of the spent nuclear fuel and radionuclides release 

    Espriu, Alexandra (Date of defense: 2017-07-17)

    Nowadays nuclear power plants (NPP) and dedicated facilities are storing the spent nuclear fuel (SNF). In the case of Spain, the NPP have enough space in their pools to keep storing the SNF produced from their activity; ...

    Syntrophic acetate oxidation in the anaerobic digestion of nitrogen-rich wastes : from microbial interactions to process optimization 

    Ruiz Sánchez, Josep (Date of defense: 2018-11-09)

    The anaerobic digestion (AD) consists of a cascade of syntrophic interactions between several microbial groups that result in the breakdown of biodegradable organic matter in the absence of oxygen, resulting in the production ...

    The use of integrative approaches to characterize new mechanisms of toxicity of pollutants in the aquatic environment 

    Rivetti, Claudia (Date of defense: 2017-05-19)

    Anthropogenic pollution represents a major concern for aquatic ecosystem, which has been affected by a complex cocktail of heterogeneous compounds that may provoke significant toxic effects to the living organisms. Among ...

    Variability of the planktonic cnidarian community at different spatio-temporal scales along the Catalan coast (Northwestern Mediterranean) 

    Guerrero, Elena (Date of defense: 2017-07-14)

    Planktonic cnidarians are those species or their stages in the phylum Cnidaria that spent their life in the water column and therefore, are tightly linked to oceanographic dynamics and water mass structures, such as fronts ...
