Periphytic and planktonic bacterial community structure in turbid and clear shallow lakes of the pampean plain (Argentina): A CARD-FISH approach

Mostrar todas las versiones(2)

Bacterioplankton and bacterioperiphyton composition was analyzed using the CARD-FISH technique in three shallow lakes of the Pampean Plain (Argentina) with contrasting regimes: clear vegetated, turbid due to phytoplankton and turbid inorganic, due to inorganic particles. We postulated that these dif...
