Molecular analysis of geographic patterns of eukaryotic diversity in Antarctic soils
We describe the application of molecular biological techniques to estimate eukaryotic diversity (primarily fungi, algae, and protists) in Antarctic soils across a latitudinal and environmental gradient between approximately 60 and 87degreesS. The data were used to (i) test the hypothesis that divers...
