    Function and structure of river sediment biofilms and their role in dissolved organic matter utilization 

    Freixa Casals, Anna (Date of defense: 2016-02-18)

    The objective of this thesis was to study how sediment microbial communities in Mediterranean rivers used dissolved organic matter at different spatial and temporal scales. Results from the two field studies, showed that ...

    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 characteristics generate ...

    Trace elements biogeochemistry in high mountain lake catchments: identifying anthropogenic versus natural components from the atmospheric contamination legacy in remote natural areas 

    Bacardit Peñarroya, Montserrat (Date of defense: 2011-06-01)

    Human activities have been interfering with the natural biogeochemical cycles of trace elements since the ancient civilizations. Although they are inaccessible and remote, high mountain lake catchments are irrefutably ...
