Microbial communities responses in fluvial biofilms under metal stressed scenarios 

Argudo Fernández, Maria (Date of defense: 2021-02-08)

This thesis shows how the metals of natural and anthropic origin change significantly the composition of the prokaryotic communities (mainly the composition of bacteria). The β-diversity is the most ...

Food webs of Mediterranean coastal wetlands 

Compte Ciurana, Jordi (Date of defense: 2010-07-21)

En aquesta tesi doctoral s'han estudiat els efectes directes i indirectes de dos tipus d'espècies claus de la comunitat aquàtica dels aiguamolls de l'Empordà (aiguamolls costaners mediterranis amb una ...

Metacommunities and biodiversity patterns in Mediterranean temporary ponds: the role of pond size, network connectivity and dispersal mode 

Tornero Pinilla, Irene (Date of defense: 2020-03-13)

We sampled the macrofaunal metacommunities in four networks of Mediterranean temporary ponds covering a wide range of pond sizes and different spatial extents. 1) In the smallest pond network, pond size ...

Reproductive and condition status of “cold water” marine fish: new insights from a changing environment 

Serrat Llinàs, Alba (Date of defense: 2019-04-10)

Exploited marine fish species with an affinity for cold waters inhabiting close to the warmer edge of their distribution area are exposed to stress caused by fishing and climate change. Three case ...

Fate and effects of copper in fluvial ecosystems: the role of periphyton 

Serra Gasa, Alexandra (Date of defense: 2009-07-03)

L'activitat humana és una de les majors causes d'elevades concentracions de nutrients i substàncies tòxiques en els ecosistemes fluvials. Entre la gran varietat de factors que alteren aquests ecosistemes, ...

Ecological interactions between an invasive fish (Gambusia holbrooki) and native cyprinodonts: the role of salinity 

Alcaraz Cazorla, Carles (Date of defense: 2006-10-02)

Actualment una de les principals amenaces a la biodiversitat és la introducció d'espècies. Revisant 26 variables de les 69 espècies de peixos continental de la Península Ibèrica concloem que la filogènia, ...

Towards the implementation of a biotechnology for biogas upgrading: role of bacteria in siloxane removal 

Boada Cahueñas, Ellana (Date of defense: 2020-07-20)

Biogas is a highly recognized alternative to fossil fuels towards a sustainable energy production. Massive use of biogas depends on the removal of contaminants that may affect performance of processing ...

Linking river sediment physical properties to biofilm biomass and activity 

Ann, Vannak (Date of defense: 2015-06-30)

River sediments are composed by a variety of grain sizes which determine their permeability and biogeochemistry. The aim of this thesis was to test whether differences in river sediment physical ...

A study on the phylogeny and the ecology of ammonia-oxidizing bacteria using a new molecular marker based on the gene amoB 

Calvó Perxas, Laia (Date of defense: 2005-05-12)

L'agricultura i la industrialització han causat un augment significatiu del nombre d'ambients rics en amoni. La presència de compostos nitrogenats redueix la qualitat de l'aigua, causant problemes de ...

Influences of toxicants on freshwater biofilms and fish: from experimental approaches to statistical models 

Tuulaikhuu, Baigal-Amar (Date of defense: 2016-06-10)

The main aims of this thesis are: i) to evaluate arsenic toxicity in two major, interacting components of the freshwater ecosystem, biofilm and fish, to provide information on environmentally realistic ...
