Genetic variation in the lichens Buellia frigida and Xanthoria elegans from the Vestfold Hills, eastern Antarctica
Entry ID: PSD1-Nottingham

[ Update this Record ]

Abstract: Antarctica is a desert continent dominated by micro-organisms. The seals and penguins, which are conspicuous around its margins, depend upon the sea for their food resources and are effectively part of the marine food chain. Life depends upon the availability of free water. In Antarctica water is usually locked up in ice, only in summer is there free water in the terrestrial environment. Not only ... View entire text

Quality DNA sequences were all double strand sequenced to ensure reliability of data. All Buellia frigida isolates gave similar results. Samples of Xanthoria elegans were more variable, suggesting an underlying taxomonic problem.
