Has been part of 2 CREAF projects Projects involved in TRANSFER Keys to understanding the transfer of atmospheric fluctuations to the dynamics of lake plankton REPLIM A network of observatories of ecosystems (lakes and peatbogs) sensitive to the climate change in the Pyrenees View projects Research groups this member belongs to GECA Grup d'Ecologia dels Canvis Ambientals firstname.lastname@example.orgOffice: C5b/-152I graduated in Biology at the University of the Basque Country in 2012. After it, in 2013 I hold a Master degree in Biodiversity and Ecosystem Functioning and Management at the same University mentioned above. In early 2015 I obtained a FPI scholarship in order to develop my PhD in one research area of the project LACUS. This PhD is supervised by Jordi Catalan and Marisol Felip. The study area of this thesis is focused in the Pyrenean high mountain lakes with a particular emphasis in the lake Redon, and the main goal is to analyze the changes in the microscopic communities at the boundary between nitrogen and phosphorus limitations. These high mountain oligotrophic lakes are largely limited by phosphorus greatly due to high nitrogen deposition of the last decades; however the situation may be reversing because of increased phosphorus deposition.Assuming that changes in the limiting nutrient should imply huge rearrangements in the microscopic communities, we use microscopic and molecular techniques to analyze the changes in planctonic and the epilithic biofilm communities.
