| phylogeography of the new zealand cicada maoricicada campbelli based on mitochondrial dna sequences: ancient clades associated with cenozoic environmental change. | new zealand's isolation, its well-studied rapidly changing landscape, and its many examples of rampant speciation make it an excellent location for studying the process of genetic differentiation. using 1520 base pairs of mitochondrial dna from the cytochrome oxidase subunit i, atpase subunits 6 and 8 and trna(asp) genes, we detected two well-differentiated, parapatrically distributed clades within the widespread new zealand cicada species maoricicada campbelli that may prove to represent two sp ... | 2001 | 11525463 |
| evaluating hypotheses on the origin and evolution of the new zealand alpine cicadas (maoricicada) using multiple-comparison tests of tree topology. | the statistical testing of alternative phylogenetic trees is central to evaluating competing evolutionary hypotheses. fleming proposed that the new zealand cicada species maoricicada iolanthe is the sister species to the major radiation of both low-altitude and montane maoricicada species. however, using 1,520 bp of mitochondrial dna sequence data from the cytochrome oxidase subunit i, trna aspartic acid, and the atpase subunit 6 and 8 genes, we inferred that both m. iolanthe and another low-alt ... | 2001 | 11158381 |
