Research lines

Study of macroalgae and marine invertebrate communities to understand the role of habitat-forming species (such as Fucus serratus) in the composition and abundance of associated communities. The aim is to determine if the transformation of these communities is due to the loss of habitat formers and / or environmental changes. In addition, the changes caused by invasive species (such as Undaria pinnatifida) in the primary production and composition of epifauna (secondary production) of the intertidal and shallow subtidal communities will be evaluated, comparing the processes of change that occur in these areas along the NW coast of the Iberian Peninsula.
