Resumen:
In
northwestern Argentina, from the border with Bolivia up to the north of
Catamarca province, there are two overlapped landscapes: the Puna plateau with
an altitude over 3500 m a.s.l., and the High Andes, known by their steep slopes.
In these regions, it is possible to differentiate diverse types of wetlands of
high biological value. They represent patches in desert regions. They also
exhibit a rare biodiversity and endemic species while serving as habitat for
many birds. This article outlines the results of studies made both on
phytoplankton and on the physical and chemical characteristics which typify
wetlands in general, showing that in these shallow lakes, rather than a true
plankton development, there is a frequent proliferation of forms adapted to the
lack of moisture. Diatoms were recognized as the most important group, both in
abundance and species richness, followed by cyanobacteria and chlorophytes.
Euglenoids, represented only by two species, were observed in very few sites.
Due to the region?s limited available information, the results from these
surveys contribute to increase signifi cantly the number of new records for
that region and for Argentina, as well as the proposals of new species to
science.
