| lack of host-dependent genetic structure in ectoparasites of calonectris shearwaters. | we compared patterns of mitochondrial dna (mtdna) differentiation in three host-specific lice (halipeurus abnormis, austromenopon echinatum and saemundssonia peusi) and one generalist flea (xenopsylla gratiosa), parasitizing 22 colonies of cory's and cape verde shearwater (calonectris). the shearwater hosts show distinct phylogeographic structure corresponding to the three taxa calonectris d. diomedea, c. d. borealis, and c. edwardsii. the host-specific lice appeared undifferentiated among the t ... | 2007 | 18028307 |
