Biodiversity and biogeographical implications of silica-scaled chrysophytes (Chrysophyceae and Synurophyceae) of the northeast wetlands of Argentina
Wetlands and water bodies in the Paraná Delta River and Iberá System of northeast Argentina were studied for scaled chrysophytes. The Delta region of the Paraná River is composed of a series of braided channels, streams and lagoons that extend over 17,500 km2. Although the Delta is situated in the t...
