Influence of flow alteration and metal pollution on stream biota: from species to community-level responses 

Rubio Gracia, Francesc (Date of defense: 2021-10-27)

This thesis aimed to assess the responses of stream biota to flow alterations, in terms of water velocity increments and reductions of discharge, and to metal pollution. The investigations performed encompassed (i) ...

Ecosystem functioning of Mediterranean confined coastal lagoons: ecosystem metabolism, main drivers and phytoplankton community 

Bas Silvestre, Maria (Date of defense: 2021-10-19)

Confined coastal lagoons are shallow and dynamic water bodies that play an important ecological role. Considering the severe degradation they have been facing in the last years, understanding the functioning of these ...

Stochastic models and the temporal dynamics of ecological communities 

Jiménez Ontiveros, Vicente Luis (Date of defense: 2020-06-29)

This thesis develops a quantitative approach to understanding and predicting the spatiotemporal distribution of biodiversity, based on a stochastic version of the theory of island biogeography. Here, I present R package ...

Agricultural practices, biodiversity and ecosystem services provided by bats in Mediterranean crops 

Puig, Xavier, 1975- (Date of defense: 2021-07-09)

We study the effect of organic farming practices on several taxa in olive groves and vineyards. Sessile organisms show a stronger response to treatment, their diversity being higher in organic vineyards. Vagile organism ...

Effects of environmental conditions on phenotypic plasticity of fishes in Iberian waters: life-history, physiological and morphological traits 

Latorre Espeso, Dani (Date of defense: 2019-10-17)

Phenotypic plasticity is the adaptive response of a genotype to presenting different types of phenotypes in response to environmental changes. These adaptive responses can contribute to a particular species being able to ...

Distribución geográfica, predicción espacial y diversidad de los hábitats litorales en la costa catalana 

Cefalì, Maria Elena (Date of defense: 2019-03-07)

According to the Habitats Directive (92/43/ECC) a habitat is defined as “the terrestrial or aquatic area, whether entirely natural or semi-natural, differentiated by its geographical, biotic and abiotic characteristics, ...

Disentangling the complexity of chemical and physical stressors impacting river systems 

Sabater Liesa, Laia (Date of defense: 2021-01-29)

At the edge of aquatic systems: intermittent streambed microbial communities’ responses to hydrological alterations 

Gionchetta, Giulia (Date of defense: 2019-10-25)

Hydrological drought is a process of natural desiccation mainly due to large shortage of rainfall events. Reduced precipitations and prolonged droughts are spreading worldwide and threaten the integrity of aquatic ...

Soil and vegetation carbon dynamics (stocks and fluxes) and litter decomposition in a Mediterranean non-tidal salt marsh 

Carrasco Barea, Lorena (Date of defense: 2020-10-09)

Biofilm responses to flow intermittency in Mediterranean rivers 

Colls Lozano, Miriam (Date of defense: 2020-07-31)

Currently, global change is promoting the spatiotemporal occurrence of temporary streams, altering fluvial ecosystem function and structure, and the ecosystem services they provide. To effectively protect fluvial ecosystems, ...
