Influence of soil texture, climate and vegetation cover on secondary soil salinization in pampas plains, South America. by Milione, German, Mujica, Claudio, Dominguez Daguer, Diego, Bea, Sergio, Fernandez, María Elena, Gyenge, Javier

“…Land-use change from herbaceous to woody cover -or vice versa- largely affects water fluxes, which in turn can mobilize existing salts dissolved in the soil, and thereby negatively affect soil and/or water quality and site productivity. The objective of this study was determine the occurrence of the soil salinization process associated to the afforestation in the Austral Pampas, considering the differences in water balance, soil texture and the presence of petrocalcic horizons that differ from the sites where secondary salinization was observed at the Northern and Eastern subregions of the Río de la Plata Grassland. …”

Floristic associations and filtering ability of riparian vegetation strips = Asociaciones florísticas en franjas de vegetación ribereña y sus capacidades de filtrado by Giaccio, Gustavo Carlos María, Laterra, Pedro, Cabria, Fabian Nestor

“…The analysis of lateral flow runoff of superficial nutrients and sediments from an agricultural origin and their retention by infiltration of riparian vegetation strips are of great importance in reducing the agricultural externalities on surface water quality. The aim of this study was to relate soil infiltration to the main biophysical properties of riparian environments in the Pampa Austral of Argentina, defined by the composition of its plant community and the coverage of exotic species. …”

Effects of livestock on the quality of the riparian forest, soil and water in Nothofagus silvopastoral systems by Gomez, Federico Antonio, Tarabini, Manuela Mabel, La Manna, Ludmila Andrea, Von Müller, Axel

“…In addition, livestock contributes faeces and urine into streams, producing the entry of sediment, nitrogen, phosphorus, and bacteria that negatively affect the quality of the water. The decrease of water quality is particularly accentuated in hot and dry years. …”

Freshwater pearl mussel as indicators of Swedish streams - a comparison between freshwater pearl mussel and biological quality elements by Forsell, Kristin

“…Because of its sensitivity to human impact, such as eutrophication, acidification and alterations of hydromorphology, the species is considered as a robust indicator of stream water quality and biodiversity. Moreover, due to the species complex life cycle, including a larval stage on the gills of salmon and trout, and sensitivity of early life stages, regeneration is often used as an indicator. …”
