Resumen:
We characterized land use, dissolved nutrients, and periphytic biomass in 23 Patagonian Andean streams. Nutrient export, especially dissolved nitrogen increased 24 with human population density. However, no correlation between nutrient concentration 25 and algal biomass was found, which could instead be limited by riparian vegetation 26 cover. Our results suggest that local N-limited ecosystems are liable to eutrophication 27 by increased demographic pressure and that alternative wastewater treatment strategies 28 are necessary for sustainable growth.
