Canals Merseburger, Mª Goretti (Data 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 (Data 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 (Data 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 (Data 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 (Data 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 (Data 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 (Data 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 ...
