Postdoctoral researcher at Cadiz University with a project about seagrass meadows, carbon dynamics and food webs.
Cádiz University (UCA), Spain
Research Experience
PhD student (2013-2017). Advisors: Dr. Juan José Vergara and Dr. Fernando G. Brun. Conducted PhD thesis about herbivory on seagrass communities. I worked on mesocosms and fieldworks experiments to evaluate the role of leaf strategies, plant reponses and effects of abiotic (i.e. temperature, acidificacition, eutrophication, hydrodynamic) and biotic factors to seagrass grazing. Conducted experiment to study the eutrophication effects on Cymodocea nodosa communities in two consecutive years. Co-authored a paper on the first study that revealed the inhibitory effect of ammonium on phosphate uptake in seagrasses. Co-authored of several works about carbon metabolism and dissolve organic carbon on coastal communities in Cadiz bay. Conducted experiment to examine the existence of and internal plant clock leading to leaf loss using a biomechanical analyses.

Research stay (July 2014-Ocotber 2014)
Race-track flume experiment about hydrodynamic effects on feeding rates and swimming behaviour of seagrass mesograzers. Controlled mesocosm experiment to asses the hydrodynamic effects on carbon metabolism and dissolved organic carbon in seagrass communities. Guest researcher (August 2011) Mesocosms experiment to gaining insight into the mechanisms controlling the availability of resources for filter feeders inhabiting seagrass canopies, both from physical and biological perspectives. Fieldwork to address the effects of variation in vegetation complexity on associated macrobenthic infauna with respect to abundance, species richness, composition, weight and body type.
