Phytoplankton chlorophyte structure as related to ENSO events in a saline lowland river (Salado River, Buenos Aires, Argentina)

Abstract: We analyzed the phytoplankton present in the lower sector of the Salado River (Buenos Aires, Argentina) for 10 years (1995–2005) and detected significant changes occurring in chlorophyte abundance and species richness during La Niña event (1998–1999), which period was analyzed throughout the entire basin (main stream and tributaries). We compared the physicochemical and biologic variables between two El Niño–La Niña–Southern Oscillation (ENSO) periods – El Niño (March 1997–January 1998) and La Niña (May 1998–M… Show more

“…Therefore the flushing effect that is generated during periods of El Niño, due to a higher flow and lower water residence time, promotes the dilution of phytoplankton, changing its concentration. Variations in community structure were observed in others rivers of the region, also associated with fluctuations in the fluvial discharge (Zalocar de Domitrovic et al, 2007;Devercelli, 2010;Solari et al, 2014).…”

“…En general durante los "años Niño", se producen mayores precipitaciones en gran parte del territorio argentino (SMN, 1999). Los dos eventos El Niño más intensos se produjeron en 1982-83 y en 1997-98, resultando en importantes inundaciones en el área de la cuenca del río Salado y otras áreas del país; una situación opuesta se registró en 1988-89 con un evento La Niña extremadamente intenso cuyo impacto fue una sequía considerable (Camilioni y Vera, 2006;Solari et al, 2014).…”
