n1_4mer:GRV/n1_4mer:RV = (Global Relative Variance of OU patterns) / (Local Relative Variance of OU patterns)
n0_4mer:D = Distance between local and global OU patterns
n0_4mer:PS = Distance between 2 strands of same DNA molecule
Selected loci indicated by large D, increased GRV associated with decreased RV and moderate increase in PS

Host Lineage: Sulfolobus islandicus; Sulfolobus; Sulfolobaceae; Sulfolobales; Crenarchaeota; Archaea
General Information: Sulfolobus islandicus is a thermo-acidophilic archeae commonly identified in hot, acidic sulfur springs. This organism can grow both chemoautotrophically, using sulfur or hydrogen sulfide, and heterotrophically. S. islandicus can play host to a number of plasmids and viruses which may be useful in developing tools for genetic analysis. In addition, Sulfolobus islandicus isolates from different areas in Russia, Iceland, and the USA have been shown to be genetically distinct from each other making this organism useful for comparative analysis.
