A. MORALES, Eduardo; L. VIS, Morgan; FERNANDEZ, Erika  and  KOCIOLEK, J. Patrick. Epilithic diatoms (Bacillariophyta) from cloud forest and alpine streams in Bolivia, South America II: A preliminary report on the diatoms from Sorata, Department of La Paz. RevActaNova. [online]. 2007, vol.3, n.4, pp.680-696. ISSN 1683-0789.

A total of seven epilithic samples were collected from streams along an altitudinal gradient within the Bolivian Cloud Forest region near the capital La Paz. The diatom flora is diverse and no clear altitudinal trends were found.  The flora is composed of cosmopolitan species and taxa restricted in distribution to the Andes with the genera Gomphonema, Nitzschia, Encyonopsis, and Encyonema containing the greatest number of species and individuals with higher frequencies in samples.  Diatoms from this region are also represented by several alkaliphilous and alkalibiont taxa reflecting the high pH of the streams. General characteristics of the sampled sites as well as a list of taxa and figures of representative taxa are presented herein.
