| phylogeography of the circumpolar paranoplocephala arctica species complex (cestoda: anoplocephalidae) parasitizing collared lemmings (dicrostonyx spp.). | the paranoplocephla arctica complex (cyclophyllidea, anoplocephalidae), host-specific cestodes of collared lemmings dicrostonyx, include two morphospecies p. arctica and p. alternata, whose taxonomical status now must be considered ambiguous. the genetic population structure and phylogeography of the p. arctica complex was studied from 83 individuals sampled throughout the holarctic distribution range using 600 bp of the mitochondrial cytochrome c oxidase subunit i gene (coi). the mitochondrial ... | 2003 | 14629352 |
