Periphytic diatoms of a mountain river (Tucumán, Argentina)
In the framework of the study of the periphytic diatomoflora (epiliton and epi- phyton) of the San Javier River (Tucumán, Argentina) we identified 40 genera and 115 infrageneric taxa of which 5 are new records for Argentina: Gomphonema lippertii, Navicula densilineolata, Placomeis neoexigua, Stauroneis adamsiana y Ulnaria ramesi. In addition, 6 are new records for Tucumán: Encyonema neomesianum, Halamphora normanii, Hantzschia abundans, Navicula antonii, N. rostellata y Placoneis symmetrica. We observe that the increase in conductivity produced by the water input from a tributary caused a decrease in the specific richness of the epiphyton and in the abundance of both communities.
