Phylogeographical pattern of Euplotes nobilii, a protist ciliate with a bipolar biogeographical distribution
Abstract Nuclear (18S and ITS ) and mitochondrial (16S) ribosomal RNA gene sequences were determined from genetically distinct wild‐type strains of Antarctic (nine strains), Fuegian (four strains), Greenland (nine strains) and Svalbard (three strains) populations of the marine ciliate, E uplotes nob...
