Marcé Romero, Rafael (Date of defense: 2007-05-29)
The role of the materials coming from the watershed on the reservoir water quality is an emergent area of high scientific interest with many practical implications. In this study we investigated the influence of the materials ...
Rovira Torres, Laia (Date of defense: 2013-11-21)
The general aim of the thesis was to improve knowledge of the ecology and taxonomy of estuarine benthic diatoms in a highly stratified Mediterranean estuary, in order to evaluate their potential use as bioindicators of ...
Caraballo López, Tatiana (Date of defense: 2013-12-13)
Phytoplankton embraces a large diversity of life forms, from pioneer oxygenic photosynthetic cyanobacteria to a broad spectrum of phylogenetically distant eukaryotic organisms. In many of the evolutionary branches, colonial ...
Lupón i Navazo, Anna (Date of defense: 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 of riparian zones on ...
Peipoch Güell, Marc (Date of defense: 2014-06-25)
The main goal of this thesis is to investigate how (15)N natural abundances can help understanding the role of different primary uptake compartments (i.e., biofilm, filamentous algae, bryophytes, macrophytes; PUCs) on ...
Roca Carceller, Guillem (Date of defense: 2015-07-06)
Nearshore marine ecosystems like seagrass meadows face a wide range of anthropogenic influences, impacting the system at different spatial and temporal scales. Managing these systems in the face of these pressures requires ...
Fabrés Francés, Joan (Date of defense: 2002-11-19)
El desenvolupament de models acurats pels cicles biogeoquímics d'elements clau, especialment pel carboni,depèn del coneixement dels fluxos d'aquests elements a través dels límits de l'oceà. La quantificació delsfluxos entre ...
Costalago Meruelo, David (Date of defense: 2012-12-10)
In the northwestern Mediterranean anchovy and sardine are among the most ecologically and economically important species. Both species are planktivorous during all their life stages, which could alledgedly lead to expect ...
Verkaik, Iraima (Date of defense: 2010-12-09)
Wildfire effects on macroinvertebrate communities have not been intensively studied in other areas than the Western US, and the results in fire prone areas like NE Mediterranean and SE Australia are scarce. In this study, ...
