Farina, Simone (Data de defensa: 2015-07-10)
Many nearshore temperate coastal ecosystems are strongly regulated by top-down control. This is particularly true of shallow macrophyte communities, where habitat structuring is heavily dependent on the ability of predators ...
De Pedro Puente, Xavier (Data de defensa: 2007-11-26)
En aquesta tesi doctoral s'han estudiat les causes de l'aparició de fenòmens hipòxics i anòxics en un sistema costaner estuarià micromareal com la badia dels Alfacs (Mediterrani NW), pel període comprès entre el final dels ...
Catalán García, Núria (Data de defensa: 2013-09-13)
Dissolved organic matter (DOM) is a primary source of organic carbon in aquatic ecosystems. Inland waters actively transform DOM, having a relevant effect on the regional and global carbon budgets. DOM quantity and quality ...
Vilalta Baliellas, Elisabet (Data de defensa: 2004-07-26)
The role of natural biofilms affecting the water quality in rivers has been the main theme in this study. Firstly, the study developed the capacity of biofilms in retention and/or production of DOC. Secondly, the study ...
Marcé Romero, Rafael (Data de defensa: 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 (Data de defensa: 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 (Data de defensa: 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 (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 of riparian zones on ...
Peipoch Güell, Marc (Data de defensa: 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 (Data de defensa: 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 (Data de defensa: 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 (Data de defensa: 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 (Data de defensa: 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, ...
