Diatoms from a patagonic-antarctic transect
This study analyses the geographical variations in the floristic composition and in the species richness of diatoms taken from 85 water bodies along a transect included in the southern Santa Cruz province, south of Tierra del Fuego province and maritime Antarctica (South Shetland Islands and Antarct...
