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 ...

    Estudio de la red trófica microbiana en lagunas someras: autotrofia versus heterotrofia 

    Àvila Izquierdo, Núria (Date of defense: 2017-05-26)

    Autotrophic and heterotrophic microorganisms are two essential functional units in the microbial food web of aquatic ecosystems. They play a key role in nutrient cycling and carbon flow and influence the structure, composition ...

    Leaf litter decomposition in Mediterranean streams: microbial processes and responses to drought under current global change scenario 

    Mora Gómez, Juanita (Date of defense: 2014-12-19)

    This thesis studied the principal environmental controlling factors and microbial mechanisms involved in leaf litter decomposition in Mediterranean intermittent streams. Additionally, drought disturbance in both Mediterranean ...

    Microbial community assembly and biogeography in the Pyrenean lacustrine district 

    Ortiz Álvarez, Rüdiger (Date of defense: 2018-05-18)

    The microbial metacommunity of the Pyrenees mountain range has never been studied at the regional level. In this PhD thesis, the main goal is to describe the taxonomic diversity and reveal the ecological processes (biotic ...

    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 ...

    Zooplankton structure and dynamics in Mediterranean marshes (Empordà Wetlands): a size-based approach 

    Brucet Balmaña, Sandra (Date of defense: 2003-11-04)

    Zooplankton community structure (composition, diversity, dynamics and trophic relationships) of Mediterranian marshes, has been analysed by means of a size based approach. <br/>In temporary basins the shape of the biomass-size ...
