Assessment of the environmental quality of two urbanized lotic systems using multiple indicators
(John Wiley & Sons Ltd, 2017-09-03)
Urbanization impacts ecosystems, generating habitat loss and fragmentation, loss of diversity, increase in runoff and contaminant discharges, and the establishment of exotic species. Potrero de los Funes Village (San ...
Phosphorus and nitrogen fractions during base flow conditions of a Pampean stream and their relationship with land use
(Asociación Argentina de Ecología, 2020-12)
During the last decades, population growth and the associated intensification of anthropogenic activities (agriculture, industrialization and urbanization) increased nutrient inputs to Pampean lotic waterbodies. However, ...
