Phytoplankton and water quality in a shallow lake: A response to secondary salinization (Argentina)

Mostrar todas las versiones(2)

This study analyzes the phytoplankton structure and dynamics, as well as the main limnological characteristics in Los Coipos Lake, located in the Reserva Ecológica Costanera Sur (Buenos Aires, Argentina). Phytoplankton generic composition was studied before (April-June 1998), during (July 1998-Decem...
