An assessment of the value of nuclear and mitochondrial genes in elucidating the origin and evolution of Isotoma klovstadi Carpenter (Insecta, Collembola)
In order to infer the origin and the evolution of Antarctic Collembola, a correct phylogenetic analysis depicting relationships among Antarctic and non-Antarctic species is required. A preliminary assessment of the value of DNA sequences in reconstructing phylogenetic relationships among the Antarct...
