| genetic variation in the mitochondrial cytochrome c oxidase subunit 1 within three species of progamotaenia (cestoda: anoplocephalidae) from macropodid marsupials. | sequence variation within 3 morphologically defined species of the anoplocephalid cestode genus progamotaenia (p. ewersi, p. macropodis and p. zschokkei) was investigated using the cytochrome c oxidase subunit 1 gene. the magnitude of genetic variation detected within each morphospecies suggests that, in each instance, several cryptic species are present. within p. ewersi, 5 genetically distict groups of cestodes were detected, 1 shared by macropus robustus and m. parryi in queensland, 1 in m. a ... | 2005 | 15700763 |
