| deep mitochondrial dna lineage divergences within alberta populations of dermacentor albipictus (acari: ixodidae) do not indicate distinct species. | the winter tick dermacentor albipictus (packard) has a single-host life cycle that allows it to reach severe infestation levels on ungulates, particularly moose. genotypic variation within these and related ticks has been a source of taxonomic confusion, although the continuity in their morphology and life history has generally been interpreted as indicating the existence of a single species. to further investigate this variation, we sequenced regions of two mitochondrial dna (mtdna) genes (coi ... | 2010 | 20695271 |
