Factores ambientales controladores del fitoplancton con énfasis en las cianobacterias potencialmente tóxicas en un lago somero utilizado como fuente de agua para potabilización: Laguna del Sauce, Maldonado, Uruguay

Abstract

Laguna del Sauce, principal fuente de agua para potabilizacion en Maldonado, Uruguay, ha registrado recurrentes eventos de floraciones de cianobacterias potencialmente toxicas, que comprometen su uso como tal. Esto ha denotado la necesidad de un mayor conocimiento de los factores ambientales asociados a la composicion fitoplanctonica y, en especial, a la ocurrencia de floraciones de cianobacterias. Mediante muestreos semanales estivales (2015-2016) de variables fisicoquimicas, nutrientes y fitoplancton, en seis sitios de Laguna del Sauce, se analizaron los factores ambientales asociados a la biomasa y composicion fitoplanctonica, particularmente de cianobacterias. La alta variabilidad temporal y espacial observada en la composicion fitoplanctonica presento alternancia de floraciones de cianobacterias: Dolichospermum crassum, Cuspidothrix issatschenkoii, Microcystis aeruginosa, Microcystis panniformis y Sphaerocavum brasiliense. La turbiedad fue clave para regular la biomasa fitoplanctonica, mientras que la relacion Nitrogeno total (NT):Ortofosfato (PO4) se asocio a la presencia diferencial de especies de cianobacterias. El analisis de las relaciones entre estos nutrientes puede contribuir a anticipar la ocurrencia de floraciones de diferentes especies de cianobacterias en este ecosistema, posibilitando la implementacion de medidas de gestion orientadas a disminuir sus efectos adversos y, en particular, a asegurar el proceso de potabilizacion.
