Patterns of population genetic structure for springtails and mites in southern Victoria Land, Antarctica
We sequenced the mitochondrial (mt) DNA cytochrome c oxidase subunit I gene to examine comparative phylogeographic patterns for the springtail Gomphiocephalus hodgsoni and the mite Stereotydeus mollis throughout their ranges in southern Victoria Land, Antarctica. Our aim was to extend previous genet...
