Pascual Barrera, Alina E. (Date of defense: 2013-06-26)

Actualmente, la problemática que enfrentan las zonas costeras del Mediterráneo en general y la Comunidad Valenciana en particular, es la generación de grandes cantidades de agua residual urbana, principalmente durante la ...

Biogeochemical controls of the transport and cycling of persistent organic pollutants in the polar oceans

Galbán Malagón, Cristóbal (Date of defense: 2013-09-20)

Humanity is currently using more than 200000 synthetic organic compounds in many industrial, agricultural and domestic applications. Many of these chemicals reach the environment and have a harmful effect on ecosystems and ...

Expressió gènica en microorganismes marins

Coll Lladó, Montserrat (Date of defense: 2013-09-27)

Ara que es comença a treure l’entrellat -o si més no a tenir una nova perspectiva- de la diversitat de microorganismes present als oceans gràcies a la biologia molecular i a la metagenòmica, el següent pas és esbrinar ...

Ecology of the marine copepod genus Oithona

Zamora Terol, Sara (Date of defense: 2013-09-29)

Copepods have a crucial role in the pelagic marine ecosystem, for their participation in the nutrient cycling and carbon export in biogeochemical cycles, and their role as link organisms between primary producers and higher ...

Sediment dynamics and associated heavy metals in small river-and wave-dominated inner shelf (Barcelona city, Nw Mediterranean)

López Fernández, Laura (Date of defense: 2013-10-24)

Wave storms and river inputs have been found to be the dominant forcing mechanism of sediment transport in continental shelves dominated by medium to large rivers around the world (e.g. Drake and Cacchione, 1985; Sherwood ...

Coral reef ecosystem services economic valuation experiences from the South Pacific

Pascal, Nicolas (Date of defense: 2013-11-11)

Economic approaches through ecosystem services (ES) valuation are increasingly recommended by conservation organisations to face main market externalities affecting biodiversity in general and coral reef ecosystems. In ...

Distribution and partitioning of organic pollutants and effects in coastal birds

Vicente de Bobes, Joana (Date of defense: 2013-11-14)

Coastal areas are very susceptible to contamination due to the interaction of marine and anthropogenic processes. Persistent Organic Pollutants (POPs) are organic compounds very resistent to photolysis and chemical and ...

Distribution and population biology of pelagic decapod crustaceans of the western Mediterranean

Silveira Simão, Daniela (Date of defense: 2013-11-22)

The present thesis provides new information about pelagic decapod crustaceans, specially so concerning the Mediterranean pasiphaeids. Remarkable differences in the pattern of distributions of the pasiphaeids were observed ...

The diversity of dinoflagellates belonging to the gymnodiniales from the catalan coast (NW Mediterranean Sea)

Reñé Vicente, Albert (Date of defense: 2014-02-28)

Dinoflagellates are one of the most abundant and diverse groups of microalgae. Many dinoflagellates are covered with cellulose plates, whereas others lack these plates and are hence referred to as athecate or unarmoured. ...
