Changes in the phytoplankton of Lake Planetario after a restoration process

Mostrar todas las versiones(2)

Lake Planetario is an urban recreational lake that suffered a Microcystis aeruginosa bloom in March 1999. At the same time the birds and fishes that inhabited the lake died, probably affected by microcystin, hepatotoxin that some strains of Miycrocyistis produce. The City of Buenos Aires requested A...
