It is predicted that climate change will affect the natural flow regime and increase the frequency and intensity of flood events that will affect freshwater communities, aquatic ecosystem functioning, and associated ecosystem services. Altered flow regimes might affect ecosystem functioning through changes in key species such as fish predators, which may cascade down to basal consumers and primary producers. My project will answer the following questions: 1) how the alteration of the frequency and magnitude of floods may affect stream ecosystem functioning; 2) what is the role played by fish on these effects; and 3) how changes in stream functioning will affect the provisioning of ecosystem services. This will be a multidisciplinary project that will combine field and mesocosm studies. On the one hand ecosystem processes will be measured every two months in 3 streams upstream and downstream flood control dams to investigate the effect of the different intensity of floods. In the other hand we will measure the same ecosystem processes in a mesocosm study where flow regimen and fish presence will be manipulated to test the interactions between floods and presence of key species. Ecosystem processes directly linked to ecosystem services will be measured, paying special attention to services related to water purification (nutrient retention), opportunities for recreation (angling, fish abundance), and food provisioning (fish secondary production). An important aspect of this project is that we will try to link ecosystem process rates with ecosystem service values.
I coursed my degree in Biology between 2003 and 2008 at the University of the Basque Country (Spain). In 2010 I obtained my Master’s degree on Ecosystems biodiversity, functioning and management at the same university. I obtained my PhD degree in May of 2014. During my Masters and PhD degree my research was mainly focused on applied ecology testing the effects of dead wood restoration on the dynamics of organic matter and on macroinvertebrate communities in streams. I did two short stays during my PhD studies, one at the University of Minho (Portugal) and the other at Roehampton University (London, UK) under the supervision of Dr Claudia Pascoal and Dr Julia Reiss respectively. After I obtained a short postdoctoral grant from the University of the Basque Country for 9 months (20142015). I realized my second post doc at INRA ST Pee sur Nivelle, thanks to the AgreenSkills fellowship program during 2 years (2015-2017). Currently I am working as an independent researcher in collaboration with the University of Cadiz (Spain), University of the Basque Country (Spain) and the CNRS from Toulouse (France) within the Aguamod SUDOE project.
