Analysis and impact of antibiotics in marine organisms. Laboratory experiments and field studies

Serra Compte, Albert (Date of defense: 2021-03-26)

Antibiotic residues in the environment are amongst the most concerning micropollutants due to their potential impact on the natural ecosystems and human health. In this thesis, laboratory and field studies were conducted ...

(Bio)monitoring of pharmaceuticals in the Mediterranean aquatic environment and interactive effect with microplastics. Insights from field and laboratory studies

Castaño-Ortiz, Jose Maria (Date of defense: 2024-12-16)

ENG- Pharmaceuticals have been broadly detected in aquatic systems, including rivers, lakes, and coastal areas. Their widespread occurrence and accumulation in aquatic organisms have raised concerns about their ecotoxicological ...

Biofilm responses to flow intermittency in Mediterranean rivers

Colls Lozano, Miriam (Date of defense: 2020-07-31)

Currently, global change is promoting the spatiotemporal occurrence of temporary streams, altering fluvial ecosystem function and structure, and the ecosystem services they provide. To effectively protect fluvial ecosystems, ...

Factors affecting the distribution, abundance and diversity of uncultured archaeal groups in freshwater sediments

Compte Port, Sergi (Date of defense: 2018-07-03)

Archaea are abundant in extreme environments but they are also a prevalent component of microbial communities in soils, marine or freshwater plankton and sediments. Many studies highlighted the prominent role of marine ...

Flow alteration and wastewater inputs effects on freshwater communities in Mediterranean rivers

Mor Roy, Jordi-René (Date of defense: 2019-09-19)

Mediterranean rivers are characterized by high hydrological variability and heterogeneity of habitats, placing themselves amongst arid and temperate climates, and are associated with high biological diversity. On the ...

Flow intermittency patterns, organic carbon dynamics, and cultural ecosystem services in the Mediterranean

Llanos Paez, Oriana Lucia (Date of defense: 2024-02-07)

Non-perennial rivers and streams are defined as systems that cease to flow at some point in space and time along their course. These systems are widespread globally representing more than half of the global river network, ...

Influence of anthropogenic pollution on the prevalence, maintenance and spread of antibiotic resistance in aquatic microbial communities

Subirats Medina, Jessica (Date of defense: 2018-07-24)

This Thesis demonstrates that microorganisms derived from wastewater are the 2/2 main contributors to antibiotic resistance (AR) in the environment. Once there, the background chemical contamination with antibiotic ...

Stream biofilm responses to flow intermittency

Timoner Amer, Xisca (Date of defense: 2014-05-05)

Streams experiencing a recurrent non-flow phase (i.e., flow intermittency) are characteristic of world regions with arid and semi-arid climates, where Mediterranean regions are part of. During non-flow streambed sediments, ...

Towards benefit oriented rehabilitation to make degraded lakes more resilient to extreme climatic events

Armstrong, Margaret Rosé (Date of defense: 2024-10-25)

ENG- The delineation of the current geological epoch as the “Anthropocene,” derived from the prefix “anthro-” meaning “human,” aptly summarizes the sheer magnitude in which humans have affected the biosphere. For many ...
