| differences in straggling rates between two genera of dove lice (insecta: phthiraptera) reinforce population genetic and cophylogenetic patterns. | differences in dispersal abilities have been implicated for causing disparate evolutionary patterns between columbicola and physconelloides lice (insecta: phthiraptera). however, no study has documented straggling (when lice are found on atypical hosts) rates within these lineages. we used the fact that the galapagos hawk, buteo galapagoensis (gould) (falconiformes) feeds on the galapagos dove zenaida galapagoensis gould (columbiformes) within an ecologically simplified setting. the galapagos do ... | 2004 | 15380682 |
