Resumen

This PhD Thesis emphasis different perspectives. Effects of coastal eutrophication on seagrasses was studied under laboratory and field conditions. Direct effect of nutrient addition to the water column was determined, indicating that ammonium have a toxic effect over seagrass growth and production depending in season, carbohydrate pool, ammonium concentration, phosphorus availability and frequency of the ammonium addition (dose). Moreover, indirect effects (i.e. promote ephemeral algae growth) were also determined. Searching for a biomedical indicator (chlorophyll fluorescense, enzymatic or proteolytic activities) of plant stress was also assays in this thesis. Field data were used in conjunction with experimental data to develop a predictive model for seagrass growth and meadow spreading (PREMOSGAMES v 1.0). Finally, some recommendations to manage the seagrass ecosystems and adjacent littoral are given using this predictive model for the seagrass Zostera noltii.
