Aquaculture effluents are rich in organic and inorganic nitrogen compounds that may support and enhance local primary productivity, eventualy inducing eutrophication conditions that may lead to the development of harmful algae blooms.
Submarine groundwater discharge (SGD) occurs in intertidal areas, representing a largely unquantified source of solute fluxes to adjacent coastal zones, with nitrogen being constantly the keynote chemical of concern. In Olhos de Água SGD is present as groundwater springs or merely sub-aerial runoff. The occurrence of the flatworm Symsagittifera roscoffensis is described for the first time in Olhos de Água in co...
Temperature, salinity and the availability of dissolved inorganic nutrients are amongst the most important abiotic factors driving macroalgae produstions in estuarine and coastal ecosystems.
