Canals Merseburger, Mª Goretti (Fecha de defensa: 2006-04-24)
A full understanding of nutrient cycling in lotic ecosystems is crucial given the increasing influence of human activities on the eutrophication of streams and rivers. However, existing knowledge about ...
Nikolakopoulou, Myrto-Georgia (Fecha de defensa: 2021-01-29)
Freshwater degradation has been largely attributed to excess nutrient concentrations of anthropogenic origin. Freshwater degradation in combination with water scarcity are the reason of severe stress ...
Bernal Berenguer, Susana (Fecha de defensa: 2006-06-30)
The amount of dissolved inorganic nitrogen delivered to streams and groundwater has substantially increased in the last decades due to anthropogenic impacts. This fact has stimulated research on processes ...
Vázquez Garcia, Eusebi (Fecha de defensa: 2013-10-11)
The studies presented in this thesis focus on the biogeochemistry of dissolved organic matter (DOM) in an intermittent stream in a Mediterranean climate zone, with great emphasis on extreme hydrologic ...
Lupón i Navazo, Anna (Fecha de defensa: 2015-11-16)
Riparian areas are recognized to be natural filters of nitrogen (N) because they can substantially diminish the N delivery from terrestrial to aquatic ecosystems. However, understanding the influence ...
Pastor Oliveras, Ada (Fecha de defensa: 2014-06-13)
The overarching goal of this dissertation was to explore relationships between streamwater nitrogen (N) and the most representative primary uptake compartments (PUCs) in stream ecosystems (e.g. microbial ...
Ejarque Gonzalez, Elisabet (Fecha de defensa: 2014-11-17)
Rivers play a key role in the global biogeochemical functioning, as they link the biogeochemical cycles of the terrestrial and oceanic systems. In the framework of the carbon cycle, streams and rivers ...
